Dismantling (cont’d)
56
Turn the track gearbox over again. Remove the three
snap rings
20
, marking each one so that it can be
returned to its original location during assembly.
57
Loosen and remove the three reamer bolts
19
.
Note:
Because thread locking compound is used on the
reamer bolts, thermal seizure can occur, making removal
difficult. Loosen the bolts as slowly as possible. If a bolt will
not release, retighten it and then try again. Patiently
persevere until the bolts unscrew.
Note:
Having been removed the reamer bolts should ideally
not be re-used. If circumstances force their re-use, they
should first be cleaned up and renovated as detailed at the
appropriate point in the assembly instructions which follow
later.
58
Make alignment marks on holding flange
3
and spindle
2
and then remove the flange. If either the holding flange
or the spindle need replacing, replace both.
59
Turn the track gearbox over and remove the hub/spindle
securing jigs fitted at step 55.
