Overhaul

Connecting rods

25. Check the connecting rods for straightness and

twisting.

26. Check the connecting rod bushings by using the

gudgeon pin as a gauge. There must be no play. If the

bushings must be replaced, use a suitable mandrel for

the removal and installation. Make sure to install the

bushing with the oil hole coinciding with that of

the connecting rod. Ream the new bushings. The fit

is correct when an oiled gudgeon pin by its own weight

can slowly slide through the bushing.

Sea-water pump

27. The pump is equipped with two ball-bearings (1).

When disassembling, remove the locking-ring (2) in

the housing and push out the shaft, whereby the bear-

ings are following. Use a suitable mandrel to remove

the bearings from the shaft.

NOTE! Do not forget the spacer sleeve (3). Replace

the sealings (4).

NOTE! Turn the sealings correctly and make sure that

they do not block the drainage hole in the

pump-housing. Replace the O-ring (5). Install the ball-

bearings and the spacer sleeve onto the shaft and

leave a distance of 39.5 mm (1.55512 in.) from the

shaft end to the ball-bearing. Coat the shaft with

grease and “screw” it through the sealings and the

O-ring and take care not to damage them. Push in the

shaft as far as to allow the bearings to bottom and

then install the locking-ring (2).

Checking the thermostat

28.

Lower the thermostat into water and check when

heating with a thermometer if the thermostat opens at

the correct temperature. It should start opening at

60±2°C (140±4°F) and be fully open at 75°C (165°F).

With freshwater cooling (2002, 2003, 2003T). Starts

opening at 74±1°C (164±2°F), fully open at 87°C

(189°F). A faulty thermostat must be replaced.
