Filling oil in new or reconditioned engine
If your engine is new or reconditioned you should
besides the actual filling of new lubrication oil also do
the following:
1. Remove the rocker cover. Lubricate the valve
mechanism and fill the camshaft oil bath from the
cylinder head. Repeat the procedure for each cy-
linder.
2. Mount all the rocker covers. Refer to section
Tightening torques for proper torques.
NOTE! Avoid running or cranking the engine without
the rocker covers mounted.
3. Remove the lubrication oil pipe connected to the
turbo.
Fill the turbo through the opening with 2 or 3
pumps of oil from the oil fill can. This has to be
done to secure lubrication of the turbo during the
first start-up.
IMPORTANT! Do not bend the pipe. This can
block the oil supply to the turbo.
4. Reconnect the lubrication oil pipe to the turbo pro-
perly.
5. Crank the engine 3 times for maximum 10 se-
conds with the emergency stop lever in the stop
position and check if the oil pressure rises proper-
ly.
6. Start the engine and operate it for about 10 minu-
tes and check if the oil pressure rises properly.
Check the oil pan and related parts for oil leaks.
IMPORTANT! If oil pressure do not rise
immediately after start, stop the engine and
investigate. Do not restart until problem is fixed.
7. Check the oil level in the oil pan and add oil if ne-
cessary.
