5 Check the gap clearance
by fitting the rings into a new
cylinder liner before installing new piston rings. Check also the
vertical clearance in the ring grooves (chapter 06., section 06.2,
pos. 11). When installing the rings, use the piston ring pliers.
The ring joints should be located 120° in relation to each others.
Old piston rings should always be placed in the same groove
and the same way around as when taken out.
6 Clean the piston,
cylinder liner, connecting rod bearing
bore and crank pin carefully.
7 Wash the big end bearing (3).
When changing bearings,
both bearing shells should be marked with the cylinder number
in the same way as the replaced one.
8 Oil the piston and crank pin
with lubricating oil. Place
the clamp device 843002 for the piston rings around the piston.
Check that the piston rings slide into the grooves without being
damaged.
9 Turn the crankshaft.
In-line engine: Turn the crankshaft 95° from the TDC towards
the operating side of the cylinder in question.
V-engine A-bank: Turn the crankshaft 95° from the TDC
towards the A-bank of the cylinder in question.
V-engine B-bank: Turn the crankshaft 95° from the TDC
towards the B-bank of the cylinder concerned.
In V-engines, mount the upper bearings shell and the protect-
ing rails 835003 and 835004.
10 Lower carefully the piston.
Turn the piston and connect-
ing rod so that the side with the cylinder number faces the
camshaft.
In-line engine: When the connecting rod is lowered to the vicinity
of the crank pin, apply the upper bearing shell in the bearing bore
observing that the guiding flap slides into the recess of the
connecting rod.
11 Lubricate the threads
of the big end bearing screws (7)
with oil.
12 Lift the bearing cap (2)
together with the lower bearing
shell in place. Attach the connecting rod screws and tighten to
stated torque by using the stud tool 803011.
13 Screw on the nuts (1)
and tighten by hand until the
lower joint face of the big end bearing cap contacts that of the
connecting rod, starting with the lower nut.
14 Lift the distance sleeves,
861033 for the in-line engine
and 861026 for the V-engine, on to the connecting rod screws.
15 Screw on the hydraulic tools;
for the in-line engine the
hydraulic tool 861027 with the distance piece 861032 screwed
on to the hydraulic piston, for the V-engine the hydraulic tool
861027.
