Every 10.000 Km (and also after the first 2,000-3,000 Km if the car is new), check and
adjust, if necessary, the clearances in the front wheel hub bearings. For this purpose, proceed
as follows:
•
Place the car on a level ground, apply its parking brake, loosen the wheel fastening nuts,
jack up the wheel and remove it, having turned off the wheel nuts
•
Remove hub cap 8 (Fig. 51), secure a device with an indicator on steering knuckle 15 so
that the indicator finger contacts the end face of hub 2 near the tapered hole;
•
Pull the hub to yourself by hands, and set the indicator pointer to zero;
•
Measure the clearances in the hub bearings, for which purpose push the hub axially away
from your- self. If in this case the indicator readings exceed 0.15 mm, adjust clearances in
the bearings in the following way;
•
Remove the indicator, screw off nut 7 and replace it with a new one;
•
Tighten nut 7 to a torque of 20 N·m(2 kg m), rotating the hub in both directions;
•
Loosen the nut and retighten it to a torque of 7 N · m (0.7 kg · m); then, screw it off
through 20-25";
•
Install the indicator and measure clearances in the bearings. If clearances exceed 0.07 mm,
repeat the adjustment. If clearances are within 0.01-0.07 mm, fix nut 7 by staking the dents
on the nut shoulder into the slots on drive end 9 of the propeller shaft.
•
Remove the device with the indicator, install cap 8, fasten the wheel, jack down the car,
and tighten the wheel nuts all the way home.
Every 20.000 Km. replace grease in the bearings of the front wheel hubs. For this purpose
proceed as follows.
•
Remove the wheel, disconnect the brake calliper from steering knuckle 15, and take it off
brake disc 1;
•
Remove hub cap 8, screw off nut 7, take out tapered bushing 6 and remove hub 2 complete
with brake disc 1;
•
Place a support under lower wishbone 17 and screw off the nuts securing ball support 16 to
the wishbone;
•
Disconnect the shock absorber from the lower wishbone and the side steering rod from the
arm of steering knuckle 15;
•
Shift propeller shaft 18 to- wards the front axle as far as it will 90;
•
Turning steering knuckle 15 about upper wishbone ball support 19, remove the former
from the propeller shaft drive end;
•
Use the puller to remove the cones of bearings 3 and 11 with demounting rings 10 and 12
and seals 5 and 13 from the steering knuckle space. Mark the bearing cones in order to
reinstall the cones in their proper places during the assembly;
•
Remove the used grease and wash with kerosene the inner space of the steering knuckle,
outer and inner spaces of the hub, propeller shaft drive end, and bearing cones;
•
Pack 40 g of fresh grease nHTon-24 into the bearing cages, apply a uniform layer of grease
to the steering knuckle spaces between the bearings, and lubricate the splines of the
propeller shaft drive end;
•
Reinstall the bearing cones and demounting rings, and press- fit the seals;
•
Mount the steering knuckle on the propeller shaft drive end, connect the ball support to the
lower wishbone, secure the shock absorber, and connect the side steering rod to the
steering knuckle arm;
•
Install the hub complete with the brake disc on the propeller shaft drive end, and install
tapered bushing 6; screw on new hub nut 7 and adjust bearing clearances, as described
above;
