Connect the water hoses to the pump.

MD2O10, MD2020: Remove the gear for the
mechanical tachometer drive�.
Fit the drive belt to the alternator.
� Note: Mechanical tachometer driving is not used by Volvo
Penta. The gear must, however, be in position.
Note: If the tension is correct the belt should be
able to be pressed in approx. 10 mm (.40 in) be-
tween the pulleys.
16.
Open the fuel cocks. Bleed the fuel system as per
the directions on page 59.
Inspection of valve lifter and camshaft
17.
Connect the battery leads.
NOTE! If the lifter is worn over the lift surface the lifter
must be scrapped. The "dike" shows that the lifter has
not rotated. A dark stripe on the outer lift surface shows,
however, that the surface is not worn.
It is the condition of the valve lifters that determines
whether further checking of camshaft wear is
necessary.
Camshaft
Dismantling the camshaft
The cam for example may be skew worn in an axial di-
rection. This can in less severe cases be adjusted by
grinding the cams. Replace the camshaft in the event of
further damage or wear.
1.
Dismantle the cylinder head. See "Dismantling of
cylinder head" on page 25. Lift out the valve lifters
and place them in order in a rack.
Note: When replacing the camshaft all the valve lifters
must be replaced.

3.
Remove the timing gear casing. See under heading
"Dismantling of timing gear" on pages 40 and 41.
Remove the regulator sleeve from the camshaft.
