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
Removal
1 Engage the parking brake and block the front wheels.
Use the stabiliser legs to raise the rear end of the
machine.
2 Using service tool 892/00822 remove bolts A to
disconnect the propshaft from the axle, refer to
Propshafts - Removing and Replacing.
3 Disconnect the brake hydraulic hoses B from the axle
centre casing and blank off the exposed connections.
4 Disconnect the hydraulic hoses C from the steer ram
and blank off all exposed connections.
5 Loosen the road wheel retaining nuts D.
6 Prop the machine on each side as shown at E.
7 Remove the rear road wheels.
8 Position a jack underneath the balance point (see Note)
of the axle and support the axle weight.
Note: Because the drivehead assembly is offset, the balance
point of the axle is not the centre of the axle. Attach a
'cradle' to the jack that will partially embrace the axle.
9 Remove nuts F, bolts G and washers H.
10 Lower the jack and remove the axle.
Note: Some machines may be fitted with a packer (6mm
thick) under the axle mounts on both sides, as shown at X.
Replacement
1 Replacing is the reverse of the removal sequence.
2 Apply JCB Threadlocker & Sealer to the threads of
bolts A.
