Pistons in Cylinders, Installation

NOTICE! After replacing the crankshaft, piston or pis-
ton pin, the weight difference between connecting rods
with piston and piston rings must not exceed 10 g
(0.0022 lbs) between cylinders. Also refer to Pistons,
Installation page 68 and Assembling Piston, Piston
Rings and Con Rod page 89.
1 Lubricate the pistons and piston rings with engine
oil and rotate the rings so that the oil finds its way
into the piston ring grooves. Rotate the piston
rings so that the ring gaps are staggered 90° from
each other.
Make sure that no piston ring gap is placed in line
with the piston pin.
2 Put the bearing shells in their places in the con-
necting rods and caps. Oil the bearing journals
with engine oil.
3 Check that the markings on the piston crown or
inside the piston tally with those on the connect-
ing rod.
Use a piston ring compressor (1) and install the
piston with connecting rod in its cylinder, starting
with cylinder no. 1 (front).
IMPORTANT!
Make sure that the connecting rod studs to not
strike the crankshaft when tapping down the pis-
ton.
The connecting rod with the lowest number must
be installed at the front (in cyl. no. 1) and the con-
necting rod with the highest number closest to the
flywheel.
The connecting rods must be turned so that the
mark (number / color mark) is facing towards the
injection pump (camshaft side).
4 Install the bearing caps (2) and tighten the con
rod bolts. For tightening torques, refer to Tight-
ening torques page 9. Big end bearing caps must
be installed so that the number markings / paint
marks on the connecting rod and cap tally.
Undamaged connecting rod bolts do not need to
be changed, but may be reinstalled.
5 Install the oil suction pipe (3) and oil strainer (4).
For tightening torques, refer to Tightening tor-
ques page 9. Use a new O-ring.
IMPORTANT!
Do not press the oil suction pipe down to the bot-
tom of the hole. There is a risk that an oil duct
could be blocked.
6 Install the oil pan together with a new gasket. For
tightening torques, refer to Tightening tor-
ques page 9.
