Repair instructions
Checking of the oil pressure
The oil pressure can be checked by connecting a ma-
nometer with hose to the connection for the oil pressure
contact (thread size in cylinder head = 1/8"). The oil
pressure should at running speed and temperature be
150-500 kPa (1.5-5 kp/cm , 21.3-71.1 lbf/in
2
If the oil pressure is too high or too low the reducing
valve can be replaced first and then the oil pressure
checked again.
The valve is fitted on the right-hand side of the cylinder
block in front of the oil filter (Fig. 83).

Dismantling of the oil pump
1.
See under the heading "Dismantling of the timing
gears" on pages 40 and 41. Carry out the work
steps 1 to 9.
2. Remove the circlip for the intermediate gear. Take
care of the circlip, sleeve washer, spring. shims
and oil pump cover.
I nspection of the oil pump
1.
Check that the oil pump cover and the inner and
outer rotor are not worn or damaged.
2. Check the clearance between the outer and inner
rotor (Fig. 84). Max. permissible clearance
0.25 mm (.0098 in).
Note. Contact Volvo Penta service department if the
shaft journal for the intermediate gear and oil pump
needs to be replaced.

Fitting of the oil pump
When fitting the oil pump follow the items 4-10 and
12-17 under the heading "Fitting and adjustment"
(transmission) on pages 42-44.

Replacing the oil filter

A
WARNING! Hot oil can result in burn injuries.
1.
Place a collection vessel under the oil filter.
2.
Unscrew the oil filter and discard (watch out for oil
spillage). Use a filter extractor.
3. Moisten the new filter's rubber gasket with oil and
check its mating surface on the bracket.
4. Screw on the new filter by hand until the gasket
makes contact with the sealing surface, and then
tighten the filter an additional 1/2 turn.
5. Replenish if necessary the oil in the engine and
start it. Check that no leakage occurs.
Oil channels
Clean up and flush the oil channels in the engine with
cleaning liquid and then with steam or flushing oil at a
pressure of 300-400 kPa (3-4 kp/cm
i n connection with more extensive engine overhaul.
Note: Do not forget to clean the oil pressure pipe be-
tween the cylinder block and cylinder head.
Clean the drilled oil channels in the cylinder block,
crankshaft and in the connecting rods with a cleaning
brush.
