3.6 HOUSING
3.6.1 Transmission housing halves
Using an adequate drift punch, top the locating pins
(item 1, Fig. 6-1a and 6-1b) out of the housing.
Loosen and remove all hex head bolts and lock
washers (item 2 and 3, Fig. 6-1b). Using a plastic ham-
mer slightly top the split line of the case halves to break
the seal. Then remove the input side of the housing.
3.6.2 Shafts and gears
Take the gear set out of the housing
.
Intermediate shaft (item 2, Fig. 6-2).
.
Input shaft (item 1, Fig. 6-2).
.
Output shaft (item 3, Fig. 6-2).
Check all gears, bearings and three piston rings on the
input shaft (item 4, Fig. 6-2) for signs of wear or failure.
If any of the gears are damaged or showing signs of ex-
cessive wear ZF HURTH MARINE recommends repla-
cing the complete gear set.
When tapered roller bearings on the input shaft need to
be replaced, the butting rings and needle bearings
should also be replaced. To check for correct clutch op-
eration, rotate the gears on the input shaft. If it is hard
to turn the gears, the clutch is probably damaged.
