Axle Hub and Driveshaft - Dismantling
!!
WARNING
A raised and badly supported machine can fall on you.
Position the machine on a firm, level surface before
raising one end. Ensure the other end is securely
chocked. Do not rely solely on the machine hydraulics or
jacks to support the machine when working under it.
Disconnect the battery, to prevent the engine being
started while you are beneath the machine.
GEN 1-1
1 Disconnect the steer ram. Drain oil from hub.
2 Remove screws 1.
3 Lever off the planet gear carrier 2 at the levering points.
Remove and discard the 'O' ring 3.
4 Remove planet gears 4 only if defective. Note that
gears can only be removed as assemblies, which
comprise the gear, the bearing and two 'L' shaped
circlips. To remove a planet gear, first remove the
external circlip 5.
5 Pull off the planet gear assembly 4.
6 The driveshaft thrust pad 6 is drilled and tapped M6 for
removal purposes.
7 Remove circlip 7 to allow the sun gear 8 to be slid off
the drive shaft.
8 Remove Verbus Rip bolts 10. These bolts are very tight
and care must be taken not to distort the bolt heads.
Use as short an extension bar as possible with a six
sided socket. Discard the bolts after removal.
Note: Fretting between the hub swivel and annulus carrier
mating faces might be evident; this condition is normal, do
not attempt to repair.
If the hub swivel and annulus carrier are to be renewed they
must be renewed as a pair, not individually
9 Remove retaining plate 11.
10 Mark the relationship between the annulus carrier,
annulus ring and hub swivel, remove the annulus carrier
12 with annulus ring 13.
11 Remove circlip 14 to separate the annulus ring 13 from
the annulus carrier 12.
12 Pull off the bearing carrier 15 together with the outer
bearing 16.
13 Pull off the inner bearing 17.
14 Remove and discard combination oil seal 18.
15 Mark the position of top and bottom trunnions 19, undo
bolts 20 and remove trunnions 19. Withdraw the hub
carrier 21.
Note: Trunnions may be removed easily by pumping grease
through the grease nipple.
16 Using a puller, remove the trunnion seal 22 and bearing
23.
17 Remove seal 24 and needle roller bearing 25 from hub
carrier 21.
Note: Seal and needle roller bearing may be left on drive
shaft. Production axles may be fitted with foam ‘masking
rings’. These are used to protect the shaft from paint during
axle spraying. The rings can be removed and discarded.
