1. With a 30mm wrench, re-
move the six (6) plugs (48)
from the valve casing (43).
Inspect the o-rings (48A)
and replace if necessary.
Remove the complete valve
assembly (46A) by thread-
ing a 12mm bolt into the
spring retainer and pulling
straight out.
2. To disassemble the valve, screw the bolt into the retainer until
the valve plate (45) presses the valve seat (44) out of the spring
retainer. Examine all parts and replace if necessary. If the seat
doesn’t come out, use a valve puller to remove.

the manifold (43) with a
rubber mallet to dislodge
and slide off the studs.

crankcase. Remove the pressure rings (39&36A), v-sleeves
(40&36), support ring (41) and o-rings (35A) from the

fully and replace if worn. Clean all parts.
