Section 04 ENGINE
Subsection 02 (LEAK TEST)
Check also small oil injection pump lines and fit-
tings; check for air bubbles or oil column going to-
ward pump, which indicate a defective check
valve.
If the above mentioned components are not leak-
ing, block both oil hoses of the rotary valve shaft
using hose pinchers.
NOTE: If leakage stops at this point, proceed with
Rotary Valve Shaft testing.
If there is still some leakage, remove the PTO fly-
wheel to verify outer seal.
If no leak is found on the PTO side outer seal, re-
move magneto flywheel and verify crankshaft
outer seals.
Proceed with the Rotary Valve Shaft testing if
the crankshaft outer seals are not leaking.
Rotary Valve Shaft
NOTE: It is preferable to drain the injection oil
from the rotary valve shaft, but it is not mandato-
ry.
Block oil return hose of the rotary valve shaft with
a hose pincher.
