Checking for leaks
1.
Start the engine.
2.
Check for oil, coolant, fuel, air or exhaust
leaks.
3.
Tighten or renew leaking connections.
Check the overflow holes which show
whether the O-rings between the cylinder
liners and crankcase are leaking.
4.
Check whether the drain hole on the coolant
pump is blocked. If there is a leak, renew the
seal in the pump or the complete coolant
pump.
If serious leakage occurs, contact your nearest
workshop.
Checking and adjusting the
valve clearance
Checking and adjusting valve clearances should
also be done one more time after the first 500
hours of operation. Then the normal interval will
follow (every 2,000 hours).
Valve clearances should be adjusted when the
engine is cold, at least 30 minutes after running.
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
Readings can be taken from the flywheel through
openings in the flywheel housing either from
above or below depending on access when fit-
ting.
“TDC up” or ”"TDC down" is found on the fly-
wheel. Both openings are fitted with a blanking
piece on delivery.
Intake valve clearance 0.45 mm (0.018 in)
Exhaust valve clearance 0.70 mm (0.028 in)
