5. Put universal grease in the cavum of oil seal' s lip.

Assembly front oil seal.

6. Reassembly bearing gasket of drive gear, adjusting

gasket of bearing and drive gear on gear seat.

7 .Knock connecting flange by soft hammer softly and

assembly the flange on drive gear.

8 .Tighten the nut of drive gear by prescriptive torque.

9 .Turn driver gear repeatly and measure the preload

of  the drive gear bearing.

10.Assembly the differential housing which has the

outside track of half shaft bearing into the gear seat.

11.Turn adjusting gasket softly by special tool to lay

the gasket on a suitable screw thread connecting position of
gear seat.

12.Point at the marks on bearing cover and gear seat,

then assembly the bearing cover.

Do not screw too tight to lock the adjusting gasket of

bearing.

13.Tighten the left and right gasket of half shaft bear-

ing one by one and measure the windage and preload force
of driven gear. Tighten  the left and right gasket in turns to
get the prescripive windage and preload force.

When check preload force, turn the drive conic gear

repeatly to lay bearing in the right position.

14.Tighten the bolt of half shaft bearing's seat.

15.Assembly lateral locking pin.

16.Check the radial run-out of main reducer driven

gear (by micrometer).

If the difference of clearance on different position is

great, it may caused by other reasons beside driven gear
and differntial.

If the radial run-out amont of driven gear is inner the

prescriptive range while the clearance of differential hous-
ing on different position is great, replace the drive and
driven gear or differential housing.

17.Check gear contact area (refer to the explanation of adjusting).
