Dismantling and Assembly
from machine number 807173
Assembly (continued)
Thoroughly degrease capscrews 15 and 11 and mating parts,
then assemble using JCB Threadlocker and Sealer.
Inspect the brake plates 8 for signs of wear or damage. Plates
should not be renewed individually, the entire plate pack
should be renewed.
If a new plate pack is to be fitted, the overall length of the
pack (when clamped) must be between 28.1 and 28.3 mm.
The desired dimension should be achieved using shims 9 and
10 fitted between the end of the plate pack and the rear case
13. One or two additional brake outer plates may be used to
reduce the number of shims if required.
The contact surfaces of spring disc 4 should be coated with
JCB Special MPL Moly grease.
