2 Install a dial indicator in 9992479 Retainer. Place the holder

with the dial indicator across the cylinder liner. Reset the dial
indicator to zero with a couple of millimetres preload against
the cylinder block's face.

3 Measure the height between the cylinder liner and the

cylinder block's face. Measure the liner's height at two
different points diagonally opposite to each other.

NOTE!
The sealing face is convex. Always measure at the highest
point on the sealing face.

Calculate the average value of both measurements.
For correct liner height over the block face, see

block, specifications page 7

.

Cylinder

If the liner's height over the block face is higher than the
stated tolerance, then the liner shelf in the cylinder block has
to be milled. Milling should take place at an authorized
workshop.
See

Cylinder block, liners removed, milling of all liner

locations page 82

.
Mark the liner's position in the cylinder block with a magic
marker, so that it ends up in the same position when
installing. Repeat the procedure for the rest of the cylinder
liners.

NOTE!
The violet seal ring shall be installed in the bottom groove.

If the cylinder liner is installed without shims, a uniform

6

sealant bead approx. 0.8 mm (0.031 in) thick shall be applied
on the underside of the cylinder liner's collar. Leave a gap
of 1-2 mm (0.039-0.079 in) in the bead. Note that when
replacing cylinder liners, use the sealant that is supplied in
the cylinder liner kit.

NOTE!
No sealant between the adjusting shims and the cylinder
liner collar.

8 Install one of the cylinder head's bolts. Place 9992955 Puller

plate on top of the cylinder liner together with a 90 mm (3.54
in) spacer. Press down the cylinder liner with a pry bar. Install
two 9996966 Press tool to lock the cylinder liner in the

Carefully lift the crankshaft into place in the engine block.
Weight: approx. 125 kg (275 lbs)

NOTE!
Make sure that the crankshaft faces the right way in relation
to the block.

11 When the crankshaft is lowered against the main bearings,

check that they are still in correct position. Install the thrust
bearing washers so that the guide pin ends up in the
intended slot.

12 Fasten the other two thrust bearing washers with grease on

the corresponding main bearing cap. Turn the washers so
that the surfaces with oil grooves face the crankshaft's axial
bearing surfaces.

NOTE!
The thrust bearing washers are available in three different
oversizes, see

Crank mechanism, specifications page 23

NOTE!
The fixing slots mean that the thrust bearing washers can
only be installed in one position.

13 Check that the slots in the main bearings shells are located

directly opposite each other on the main bearings in the
cylinder block and bearing caps, respectively.

Install spacers approx. 40 mm (1.6 in) on the bolts for the
bearing brackets to fixate the camshaft.
Torque-tighten the bolts temporarily with approx. 60 Nm (44
lbf ft).
Check that the camshaft can be rotated while tightening.

17 Loosen the bolts for the upper transfer gear so that it can be

moved. Check by turning the camshaft gear back and forth.
When the camshaft gear is turned clockwise until it stops the
transfer gear is moved to the left so that a big backlash (gear
flank clearance) is obtained between the camshaft gear and
the transfer gear. When the camshaft gear is turned counter­clockwise until it stops the transfer gear is moved to the right
so that no backlash (gear flank clearance) is obtained
between the camshaft gear and the transfer gear.
Insert a feeler gauge 0.10 mm (0.0039 in) between the gears
and turn the camshaft gear counter-clockwise until it stops.
Then tighten down the upper transfer gear's bolts as shown
in the figure, then remove the feeler gauge.

18 Check the backlash with a rocker indicator.

Hold the transfer gear in place and turn the camshaft gear
back and forth, then compare the result with the specification
for backlash. See

24 Install the rocker arm shaft's bolts.

Check that the valve yokes are in correct position on the
valve stems.
Tighten the bolts according to the diagram in the
specifications so that the rocker arm shaft does not bend.
Make sure that the shaft is guided in the guide sleeves on
the bearing caps.
Tighten down the rocker arm shaft.

1 Hold

up the lock rod and install the cutting tool. The serrated

edge

shall face the electromagnet and the centring roller on

the side of the spindle marked R.

2 Place 9812524 Milling tool so that it is slightly displaced in

relation to the middle of the cylinder.

NOTE!
When milling with 110 V outlet, use 88890113 Milling tool
instead.

3 Set the switch to position 1 to activate the electromagnet.

4 Screw the vertical feed sleeve upwards so that the cutter can

pass freely over the liner shelf.

5 Press down the lock clamp and place the centring roller

against the liner seat's wall, where the distance to the wall
is the longest.

6 Lock the lock clamp and set the switch between position 1

and 2.

Centre the tool by turning the crank clockwise while holding

7

the horizontal feed ring in place.

8 The centring roller shall always have contact with the liner

position's wall.
If the tool loses contact with the wall:
Turn the crank backwards (counter-clockwise) while holding
the horizontal feed ring in place.

9 The tool is centred when it stops moving.

10 Then set the switch to position 1.

11 Press down the lock clamp.

12 Move the cutter so that is passes over the liner shelf without

touching the liner wall.

13 Turn the crank and the vertical feed sleeve until the cutting

tool comes into contact with the liner shelf.

14 Reset the scale ring to zero and read off on the scale.

Fig.173

15 Press down the lock clamp and move the cutter so that the

edge ends up just inside the edge on the liner shelf (the
inside diameter).

NOTE!
Set the

scale ring to max. 0.05 mm (0.002 in) for the first reworking
to check that the cutter mills evenly all the way around the whole
cylinder.
Then rework the cylinder with max. 0.15 mm (0.006 in) per
reworking.

16 Turn the vertical feed sleeve so that the cutter starts to work

against the liner shelf.

Fig.174

86

Fig.175

17 Rework the liner shelf by turning the crank clockwise while

holding the horizontal feed ring in place.

NOTE!
To avoid

collection of dwarf and chips, release the feed ring

and let the cutter rotate without feed every fifth revolution.

NOTE!
Turn the crank carefully and let the ring slide a little between
your fingers when the cutting tool approaches the liner
shelf's wall so that you can stop exactly when the cutting tool
reaches the wall.

18 Repeat the process until the desired result is obtained.

19 Loosen the electromagnet by setting the switch to position

2 and remove the tool.

20 Check the depth with a dial indicator, set for each cylinder.
