DISASSEMBLY/REASSEMBLY
A warped oil retainer may allow the introduction of air into the
engine thus causing crankcase ventilation problems.
Use genuine oil retainers with the KOHLER logo (see B).

Drive shaft oil seals

Oil retainer 1 is located in the gear cover on the timing side while re-
tainer 2 is located in the crankcase on the flywheel side.
Arrows a point to the crankshaft direction of rotation.
Press them into their seats by exerting uniform pressure throughout
their front surface.

Drive shaft, lubrication ducts, bore thread on flywheel side and p.t.o.

Remove plug C and check that the lubrication duct is perfectly clean.
Close with a new plug checking for proper sealing.
A = M14x1.5 (turn counterclockwise)
B = M8x1.25 (with standard shaft)
When the crankpin and main journal are ground, values R and
R must be obtained again to prevent the drive shaft from bre-
1
aking.

Drive shaft, connection radius

Radius R that joins the crankpin to the supports is 2.8-3.2 mm.
Radius R that joins the main journal to the timing gear is 0.5 mm.
