7.1: Extraction of KP5AX Bearings from 1 Piece Link Assembly: Figs 3,4a,4b,4c,4d
Remove all the outer shield washers (4,5,6) and wipe off old grease from the Labyrinth
areas. Assemble the link as shown in Fig 4a on top of the jaws of an engineer’s vice, sup-
porting the link whilst allowing the KP5AX bearing to be drifted out between the vice jaws.
Slide the M8x65mm bolt (7) through the top KP5AX bearing, and drift out the Centre
Spacer (3) and KP5AX bearing (2) together as shown in figure 4b. Once the Centre Spacer
(3) has been removed from the assembly, the remaining KP5AX bearings can be removed.
To remove the remaining 3 KP5AX bearings (2) from the one piece link body (1) assemble
the components as illustrated in Figure 4c. Using an inner top hat washer (4) seated in the
bearing, slide the M8x65mm bolt (7) through the top KP5AX bearing, and repeat the pro-
cedure to drift out the lower KP5AX bearing. Once these bearings have been removed, it
should be possible to remove the remaining two KP5AX bearings with a normal size drift
tool.
