filter. If water is relatively clean or if several
10 hour checks indicate cleaning is not nec-
essary at this interval, schedule cleaning at
25 hour intervals. Unscrew cover (should
come off by hand) and remove gasket and
filter basket. Clean basket with soap and
water, rinse and replace. Make sure gasket
is installed properly and replace cover hand-
tight. When engine is started, check cover
for leaks and tighten if necessary.
Check crankcase ventilation air filter and
oil valve. If vent air, mixed with oil, starts
to flow out at oil valve, this indicates
crankcase ventilation air filter is clogged
and must be changed. Unscrew old filter
and discard. Screw in new filter.
Change crankcase oil.
Run engine until operating tempera-
ture is normal.
With engine turned off, suck oil
through tube of drain pipe located on
top of engine next to oil dipstick.
Without a filter change (normally
scheduled every 200 hours), use 10 qt
to bring oil level to between marks on
dipstick. Fill through oil filler cap on
top of engine. Use diesel lubricating oil
CD (MIL-L-2104), SAE 20W30, above
50 °F and oil CD SAE 1 O0W, below 50
F. With filter change, use 11 qt of oil.
Change oil filter.
After draining oil, place a cloth
beneath oil filter and screw off old fil-
ter. Do not spill oil. If filter is difficult to
remove, use oil filter wrench or punch
a hole in filter and use long screw-
driver to remove filter.
Discard old filter. Remove old rubber
seal with old filter.
