Refitting the pump head
Fig. 59: Refitting the pump head
1. Place the sealing washers (
4
) in the appropriate recesses of
the connecting plate (
3
) and spacer plate (
8
).
2. Place the O rings (
6
) and valve disks (
7
) on the valve seats (
5
)
(see Fig. 60, middle). Check that the O rings and valve disks
are correctly positioned.
3. Place the assembled valve seats (
5+
) to fit snugly into the
connecting plate (

).
Jammed valve seats may cause the valve to malfunction.
Meticulous care is required for this assembly step.
4. Join the connecting plate (
3
) with the spacer plate (
8
), place
the cover plate (
2
) in position over them and insert the four
head bolts (
1
) in the threaded holes.
5. Push the assembled components onto the crankcase housing
with finger pressure.
6. Fasten the pump head to the housing by tightening the 4 head
bolts (
1
) alternately. Hand-tighten the head bolts.
