Link Arms - Removal and Replacement
Removal
1 Fix the assembly on a locally made strip/rebuild bench
as shown.
2 Using two suitable open ended spanners at L and M
react against each other until one ball joint unscrews.
3 Unscrew the ball joint L until an open ended spanner
can be fitted on the rod N. Screw the ball joint against
the spanner to secure the spanner and to prevent
damage to the rod.
4 By reacting against the spanner at N and M undo the
other ball joint.
Note 1: Flats at ‘E’ are:
2 Wheel drive machines - 32 mm A/F x 4 mm wide.
4 Wheel drive machines - 40 mm A/F x 4 mm wide.
Note 2: The piston rod operates at full length, any damage
to the surface will cause fluid leaks. DO NOT attempt to grip
the rod diameter with pipe grips etc.
5 Repeat the procedure for the remaining link arm
assembly.
6 Where applicable remove the target disc G.
Note 3: If the inner or outer ball joints need to be renewed,
then a replacement link arm assembly must be fitted.
Replacement
Replacement is the reverse of removal but note the
following:
1 Remember to fit the target disc G (where applicable).
2 Use JCB Threadlocker & Sealer on the trackrod link
arms.
3 If the link arms have been renewed, the wheel
alignment must be checked as follows:
a Set the wheels to the straight ahead position and
measure dimensions X and Y (at the outer edge of
the wheel hub). Alignment is correct if the
difference between X and Y is a maximum of 1
mm.
b To adjust the wheel alignment undo the lock nuts
(H or K as applicable). Turn the threaded adjusters
J equally to obtain the correct alignment. Tighten
the lock nuts (H or K as applicable).
