whichever is soonest, check the following :-
1)
Hub end float for excess.
2)
Planet pin bearing surfaces for signs of wear or pitting, renewing pins if damage is
evident.
3)
Planet and sun gears for signs of wear or pitting, renewing if damage is seen.
4)
Front wheel alignment see section no.28, page no.B35.
5)
Brake adjustment.
6)
General condition of nuts and bolts and casing.
7)
Joints / oil seals for signs of leakage.
8)
Drain and refill axle with clean gear oil - see lubrication section A for details.
Re-line brake shoes when brake liners wear down to 5/16" (8mm) thickness, measured at
9)
centre of brake shoe.
10)
Coupling flange for wear / damage.
11)
Pinion oil seals for leaks.
12)
Breathers for signs of leakage or dirt ingress.
13)
Leaks around joints.
14)
General conditions of nuts, bolts and casing.
15)
Tighness of all nuts and bolts.Adjust and replace as necessary.
Note :- Spicer Speciality Axle Divisioin recommend that brake springs are
replaced whenever brakes are re-lined.
Manufacturers of crimped metal or nylon ring locknuts recommend that they are
replaced after being re-used one time.
Note :- At the axle build, tracking is set to TD 186/1 i.e 'Toe Out'. However, where part time all
wheel drive is used the axle should be re-aligned to 'Toe In' as below:-
2.2
Check wheel alignment as follows :-
Set wheels in a straight ahead position, and at points level with wheel centre, measure distance
between edges of wheel rims both in front and behind axle centre.
For correct alignment front measurement (` A') shoul be 0" to 1/16 " smaller than that of rear (` B')
d
ie. toe-in. To allow for inaccuracies in wheels, same checks should be made with vehicle moved so that
wheels have moved a further half a revolution (see fig no. 1).
Adjust if required by slackening ball joint clamp bolts and rotating track rod tube.
DO NOT forget to re-tighten clamp bolts to 51 - 62lbs.ft. (69 - 84Nm.) after adjusting.
