    PRECAUTIONS AGAINST DAMAGE 
    1. Always fit covers  to protect  wings before 
    commencing  work in engine  compartment. 
    2. Cover  seats and carpets,  wear clean  overalls  and 
    wash  hands 
    or wear gloves  before  working  inside 
    car. 
    3. Avoid  spilling  hydraulic  fluid or battery acid on 
    paint  work.  Wash 
    off with water  immediately if this 
    occurs.  Use Polythene  sheets in boot  to protect 
    carpets. 
    4. Always  use a recommended  Service Tool, or a 
    satisfactory  equivalent, where specified. 
    5. Protect  temporarily  exposed screw threads  by 
    replacing  nuts or fitting  plastic  caps.

    Whenever  possible use a ramp  or pit  when  working 
    beneath  vehicle, in preference  to jacking.  Chock 
    wheels  as well  as applying  hand brake. 
    Never  rely 
    on a jack  alone  to support  vehicle. Use 
    axle stands  or blocks  carefully  placed at jacking 
    points  to provide  rigid location. 
    Ensure  that a suitable  form of fire  extinguisher  is 
    conveniently  located. 
    Check  that any lifting  equipment 
    uscd has 
    adequate  capacity and 
    is fully serviceable. 
    Inspect  power leads of any  mains  electrical 
    equipment  for damage  and check  that it is  properly 
    earthed. 
    Disconnect  earth (grounded)  terminal of vehicle 
    battery. 
    Do not  disconnect  any pipes  in air  conditioning 
    refrigeration  system, if fitted,  unless  trained  and 
    instructed  to do 
    so. A refrigerant  is used  which  can 
    cause  blindness  if allowed  to contact  eyes. 
    Ensure  that adequate  ventilation  is provided  when 
    volatile  degreasing  agents are being  used. 
    WARNING:  Fume extraction  equipment must be in 
    operation  when  trachloride,  methylene chloride, 
    chloroform 
    or perchlorethylene  are  used for 
    cleaning purposes. 
    Do not  apply  heat in an  attempt  to free  stiff  nuts  or 
    fittings;  as well  as causing  damage  to protective 
    coatings,  there is a risk 
    of damage  to electronic 
    equipment  and brake  lines from  stray heat. 
    Do not leave  tools,  equipment,  spilt oil etc., 
    around  or 
    on work area. 
    Wear  protective  overalls and use barrier  creams 
    when  necessary.

    Before  removing  a component,  clean it and  its 
    surrounding  areas as thoroughly  as possible. 
    Blank  off any  openings  exposed by component 
    removal,  using greaseproof  paper and masking 
    tape. 
    Immediately  seal fuel,  oil or hydraulic  lines when 
    separated,  using plastic  caps 
    or plugs, to prevent 
    loss of fluid  and entry  of dirt. 
    Close  open ends of oilways,  exposed  by component 
    removal,  with tapered  hardwood  plugs 
    or readily 
    visible  plastic  plugs. 
    Immediately  a component  is removed,  place 
    it in a 
    suitable  container;  use a separate  container  for 
    each  component  and its associated  parts. 
    Before  dismantling  a component,  clean it 
    thoroughly  with a recommended  cleaning agent; 
    check  that agent  is suitable  for all materials  of 
    component.  Clean  bench  and provide  marking  materials, 
    labels,  containers  and locking  wire before 
    dismantling  a component.

    Observe  scrupulous  cleanliness  when dismantling 
    components,  particularly when brake,  fuel or 
    hydraulic  system parts are being  worked 
    on. A 
    particle  of dirt 
    or a cloth  fragment  could cause a 
    dangerous  malfunction  if trapped  in these  systems. 
    Blow  out all tapped  holes, crevices,  oilways and 
    fluid  passages  with an air  line.  Ensure  that any 
    0
    -rings  used for sealing  are correctly  replaced or 
    renewed,  if disturbed. 
    Mark  mating  parts to ensure  that they  are replaced 
    as  dismantled.  Whenever possible use marking  ink, 
    which  avoids  possibilities 
    of distortion  or initiation 
    of cracks,  liable if centre punch  or scriber  are used. 
    Wire  together  mating parts where  necessary  to 
    prevent  accidental  interchange  (e.g. roller  bearing 
    components).  Wire  labels  on to all  parts  which  are to be  renewed, 
    and  to parts  requiring  further inspection  before 
    being  passed  for reassembly;  place these parts in 
    separate  containers  from those containing  parts for 
    rebuild. 
    Do not  discard  a part  due for renewal  until after 
    comparing  it with  a new  part,  to  ensure that its 
    correct  replacement  has been  obtained.

    							1051 GENERAL FITTING INSTRUCTIONS 
    INSPECTION - GENERAL 9. When fitting bearing  to shaft,  apply force only to 
    inner  ring of bearing,  and only  to outer  ring when 
    fitting  into housing. 
    1. Never  inspect  a component  for wear  or 
    dimensional  check unless 
    it is absolutely  clean; a 
    slight  smear  of grease  can conceal  an incipient 
    failure. 
    2. When  a component  is to  be  checked  dimensionally 
    against  figures quoted  for it, use  correct  equipment 
    (surface  plates, micrometers,  dial gauges,  etc.) in 
    serviceable  condition. Makeshift checking 
    equipment  can be dangerous. 
    3. Reject  a component  if its  dimensions  are outside 
    limits  quoted,  or 
    if damage is apparent.  A part 
    may,  however,  be refitted  if its  critical  dimension  is 
    exactIy limit size, and is otherwise  satisfactory. 
    4. Use ‘Plastigauge’ 12 Type PG-1 for checking 
    bearing  surface clearances;  directions for its use, 
    and  a scale  giving  bearing  clearances  in 
    0,0025 mm 
    (0.0001 in) steps  are provided  with it. 
    BALL AND ROLLER BEARINGS 
    NEVER  REPLACE A BALL OR ROLLER 
    BEARING  WITHOUT  FIRST ENSURING  THAT 
    1. Remove all traces of lubricant  from bearing  under 
    inspection  by washing  in petrol 
    or a suitable 
    degreaser;  maintain absolute cleanliness 
    throughout  operations. 
    2. Inspect visually  for markings of any  form on rolling 
    elements,  raceways,  outer surface 
    of outer rings or 
    inner  surface 
    of inner  rings.  Reject  any bearings 
    found  to be  marked,  since any marking  in these 
    areas  indicates  onset of wear. 
    3. Holding  inner race between  finger and thumb of 
    one hand,  spin outer  race and check  that it revolves 
    absolutely  smoothly. Repeat, holding outer race 
    and  spinning  inner race. 
    4. Rotate  outer ring gently  with a reciprocating 
    motion,  while holding  inner ring; 
    feel for any  check 
    or  obstruction 
    to rotation,  and reject  bearing if 
    action is not  perfectly  smooth. 
    5. Lubricate  bearing generously  with lubricant 
    appropriate  to installation. 
    6. Inspect  shaft and bearing  housing  for 
    discolouration  or other  marking  suggesting  that 
    movement  has taken  place between  bearing and 
    seatings.  (This is particularly  to be  expected 
    if 
    related  markings  were found  in operation 2.) If 
    markings  are found,  use ‘Loctite’  in installation 
    of 
    replacement  bearing. 
    7. Ensure that shaft  and housing  are clean  and free 
    from  burrs  before  fitting bearing. 
    8. If one  bearing of a pair  shows  an imperfection it is 
    generally  advisable  to renew  both bearings:  an 
    exception  could be made 
    if the faulty  bearing  had 
    covered  a low  mileage,  and 
    it could be established 
    that  damage  was confined  to it only.

    10. In the  case  of grease-lubricated  bearings (e.g. hub 
    bearings) 
    fill space  between  bearing and outer  seal 
    with  recommended  grade 
    of grease before fitting I 
    11. Always  mark components of separable  bearings +--* 
    (e.g. taper  roller  bearings)  in dismantling,  to 
    ensure  correct  reassembly.  Never fit new  rollers 
    in 
    a used  cup.

    seal. fa 
    OIL SEALS 
    1. Always  fit new  oil seals  when  rebuilding  an 
    assembly.  It is not  physically  possible to replace  a 
    seal  exactly  when it has  bedded  down. 
    2. Carefully  examine seal before  fitting to ensure  that 
    it  is  clean  and undamaged. 
    3. Smear  sealing  lips with  clean  grease;  pack dust 
    excluder  seals with grease,  and heavily  grease 
    duplex  seals 
    in cavity between  sealing lips. 
    4. Ensure  that seal spring,  if provided,  is correctly 
    fitted. 
    5. Place  lip of seal towards  fluid to be  sealed  and slide 
    into  position 
    on shaft,  using fitting  sleeve when 
    possible  to protect  sealing lip from  damage  by 
    sharp  corners,  threads or splines.  If fitting  sleeve  is 
    not  available,  use plastic  tube 
    or adhesive  tape to 
    prevent  damage 
    to sealing lip.

    6. Grease outside  diameter  of seal,  place  square  to 
    housing  recess and press  into position,  using great 
    care  and 
    if possible  a ‘bell  piece’  to ensure  that seal 
    is  not  tilted.  (In some  cases it may  be preferable  to 
    fit  seal  to housing  before fitting to shaft.)  Never let 
    weight  of unsupported  shaft rest in seal. 
    9 .I 
    ST1037M 
    7. If correct  service tool is not  available,  use a suitable 
    drift  approximately  0,4 
    mm (0.015 in) smaller  than 
    outside  diameter 
    of seal. Use a hammer  VERY 
    GENTLY on drift if a press  is not  suitable. 
    8. Press  or drift  seal in to  depth  of housing if housing 
    is  shouldered,  or flush  with face of housing  where 
    no  shoulder  is provided.  Ensure that the seal  does 
    not  enter  the housing  in a tilted  position. 
    NOTE: Most cases of failure  or  leakage of oil seals 
    are due  to  careless  fitting,  and  resulting damage to 
    both  seals  and  sealing  surfaces.  Care in fitting 
    is 
    essential  if good results  are to be  obtained. 
    JOINTS AND JOINT FACES 
    1. Always  use correct  gaskets  where they are 
    spccificd. 
    2. Use jointing  compound  only when  recommended. 
    Otherwise 
    fit joints  dry. 
    3. When  jointing  compound  is used,  apply  in a thin 
    uniform  film to metal  surfaces;  take great  care to 
    prevent 
    it from  entering  oilways, pipes or blind 
    tapped  holes. 
    4. Remove  all traces of old  jointing  materials  prior to 
    reassembly. 
    Do not  use a tool  which  could damage 
    joint  faces. 
    5. Inspect  joint faces  for scratches  or burrs  and 
    remove  with a fine 
    file or  oil  stone;  do not  allow 
    swarf  or dirt  to enter  tapped  holes or enclosed 
    parts. 
    6. Blow  out any  pipes,  channels  or crevices  with 
    compressed  air, renewing 
    any 0
    -rings  or seals 
    displaced  by air  blast. 
    FLEXIBLE HYDRAULIC PIPES, HOSES 
    1. Before  removing  any brake  or power  steering  hose, 
    clean  end fittings  and area  surrounding  them as 
    thoroughly  as possible. 
    2. Obtain  appropriate  blanking caps before  detaching 
    hose  end fittings, 
    so that  ports  can be immediately 
    covered  to exclude  dirt. 
    3. Clean hose externally  and blow  through  with 
    airline.  Examine  carefully for cracks,  separation  of 
    plies,  security 
    of end fittings  and external  damage. 
    Reject  any hose  found 
    faulty. 
    4. When  refitting  hose, ensure  that no unnecessary 
    bends  are introduced,  and that  hose  is 
    not twisted 
    before  or during  tightening  of union  nuts. 
    5. Containers  for hydraulic  fluid must  be kept 
    absolutely  clean. 
    6. Do not store  hydraulic  fluid in an  unsealed 
    container.  It will  absorb  water, and fluid 
    in this 
    condition  would be dangerous  to use  due  to a 
    lowering  of its  boiling  point. 
    7. Do not allow  hydraulic  fluid to be  contaminated 
    with  mineral  oil, or use  a container  which has 
    previously  contained mineral oil. 
    8. Do not re-use  fluid  bled from  system. 
    9. Always  use clean  brake  fluid to clean  hydraulic 
    components. 
    10. Fit  a blanking  cap to a hydraulic  union and a plug 
    to  its  socket  after removal  to prevent  ingress 
    of 
    dirt. 
    11. Absolute  cleanliness  must be observed  with 
    hydraulic  components  at all  times. 
    12. After  any work  on hydraulic  systems, inspect 
    carefully  for leaks  underneath  the vehicle  while a 
    second  operator  applies maximum  pressure to the 
    brakes  (engine  running)  and operates  the steering. 
    METRIC BOLT IDENTIFICATION 
    1. An IS0 metric  bolt or screw,  made of steel  and 
    larger  than 
    6 mm in diameter  can be identified  by 
    either  of the  symbols 
    IS0 M or M embossed  or 
    indented 
    on top  of the  head. 
    2. In addition  to marks  to identify  the manufacture, 
    the  head  is also  marked  with symbols  to indicate 
    the  strength  grade 
    e.g. 8.8, 10.9, 12.9 or 14.9, 
    where the first  figure  gives the minimum  tensile 
    strength 
    of the  bolt  material  in tens  of kg/sq mm. 
    3. Zinc  plated IS0 metric  bolts and nuts  are chromate 
    passivated,  a greenish
    -khaki  to gold-bronze  colour.

    METRIC NUT IDENTIFICATION 
    A A nut 
    with  an IS0 metric thread  is marked  on one 
    face  or on  one  of the  flats  of the  hexagon  with the 
    strength  grade symbol 
    8,12 or 14. Some  nuts with a 
    strength  4, 5 or 6 are also  marked  and some  have 
    the  metric  symbol 
    M on the  flat opposite the 
    strength  grade marking. 
    A clock  face system  is used  as an  alternative 
    method  of indicating  the strength  grade. The 
    external  chamfers  or a face 
    of the  nut is marked  in 
    a  position  relative to the  appropriate  hour mark  on 
    a  clock  face to indicate  the strength  grade. 
    A dot is used  to locate  the 12 oclock  position and a 
    dash  to indicate  the strength  grade. If the  grade 
    is 
    above  12, two  dots  identify  the 12 oclock position.

    HYDRAULIC FITTINGS - Metrication 
    WARNING:  Metric  and Unified  threaded  hydraulic 
    parts.  Although  pipe connections to  brake system units 
    incorporate  threads  of  metric  form, 
    those for  power 
    assisted steering are of  UNF type.  It 
    is vitally important 
    that  these  two thread  forms are  not  confused,  and 
    careful study should be  made 
    of the following notes. 
    Metric  threads  and metric  sizes are being  introduced 
    into  motor  vehicle  manufacture  and some  duplication 
    of  parts  must be expected.  Although standardisation 
    must  in the  long  run be good, 
    it would  be wrong  not to 
    give  warning  of the  dangers  that exist  while  UNF and 
    metric  threaded  hydraulic  parts continue  together in 
    service.  Fitting UNF pipe nuts into metric  ports and 
    vice
    -versa  should  not happen,  but experience  of the 
    change  from BSF 
    to UNF indicated  that there  is no 
    certainty  in relying  upon the difference 
    in thread  size 
    when  safety  is involved.

    AI1 metric  ports in cylinders  and calipers  have no 
    counterbores,  but unfortunately  a few  cylinders 
    with  UNF  threads  also have  no counterbore.  The 
    situation  is, all  ports  with counterbores  are UNF, 
    but  ports  not counterbored  are most  likely  to be 
    metric.

    The greatest  danger lies  with  the  confusion  of 
    10 mm and 2 in UNF pipe nuts used for in (or 
    4,75 mm) pipe.  The 3 in UNF pipe nut or hose  can 
    be  screwed  into a 
    10 mm port  but is very  slack  and 
    easily  stripped.  The thread  engagement  is very 
    weak  and cannot  provide  an adequate  seal. 
    The  opposite  condition,  a 
    10 mm nut in a  in port, 
    is difficult  and unlikely  to cause trouble. The 10 mm 
    nut will  screw  in 1; or 2 turns and seize.  It has  a 
    crossed  thread ‘feel’ and it 
    is impossible  to force  the 
    nut  far enough  to seal  the pipe.  With  female  pipe 
    nuts  the position  is of  course  reversed. 
    The  other  combinations  are 
    so different that there  is 
    no  danger 
    of confusion.

    slacken 
    it back to insert  split  pin  or locking  wire 
    except  in those  recommended  cases where  this 
    forms  part 
    of an adjustment.  If difficulty  is 
    experienced,  alternative washers or nuts 
    should be 
    selected,  or washer  thickness reduced. 
    2. Where  self-locking  nuts  have been removed it is 
    advisable  to replace  them  with new ones 
    of the 
    same type. 
    NOTE: Where  bearing  pre-load is involved  nuts 
    should  be tightened  in accordance  with  special 
    instructions. 
    LOCKING WIRE 
    1. Fit  new  locking wire of the  correct  type for all 
    2. Arrange wire so that its tension tends  to tighten  the 
    assemblies incorporating 
    it. 
    bolt 
    heads, or nuts, to which it is  fitted. 
    SCREW  THREADS 
    1. Both UNF and Metric  threads to IS0 standards are 
    used.  See below  for thread  identification. 
    2. Damaged thrcads must always  be  discarded. 
    Cleaning 
    up threads  with a die or tap  impairs  the 
    strength  and  closeness of fit  of the  threads  and  is 
    not 
    recommcndcd. 
    3. Always  ensure  that  replacement  bolts are  at  least 
    equal 
    in strength to those rcplaced. 
    4. Do  not  allow  oil,  grease  or jointing  compound  to 
    enter  blind threaded  holes. The hydraulic  action on 
    screwing 
    in the bolt  or stud  could split  the housing. 
    5. Always tighten a nut or bolt to the  recommended 
    torque  figure.  Damaged  or corroded  threads 
    can 
    affect the torque  reading. 
    6. To check or re-tighten a bolt or screw to a specified 
    torque  figure,  first slacken a  quarter 
    of a turn,  then 
    re
    -tighten  to the correct figure. 
    7. Always  oil thread  lightly before  tightening to 
    ensure a free  running  thread, except in the  case  of 
    self
    -locking  nuts. 
    1. Fit new split  pins  throughout  when replacing  any 
    unit. 
    2. Always fit split pins  where split pins were  originally 
    used. 
    Do not  substitute  spring washers:  there is 
    always  a good reason for 
    the use of a split pin. 
    3. All  split  pins should  be fitted  as shown  unless 
    otherwise  stated.
