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 (3).
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.
Recommended torque: max. 0.55 Nm
