RUBBER COUPLING INSPECTION AND REPLACEMENT INSTRUCTIONS
Note: This procedure is a two person
operation and must only be attempted with
the engine completely COLD!
The rubber coupling is part of the transmission
system of the Evo-engine. It is a 'wearing part'
and should be checked every 250 hours for
serviceability. The following instructions are
intended for owner/operators who are familiar
with and have competence/experience in the
maintenance procedures required for small
capacity 4 stroke petrol engines. If you do not
feel completely confident with the following
instructions, please contact our helpline for extra
advice.
• Note the position of the recoil starting handle
for future re-installation. Remove the recoil
starting system by undoing and removing the
3 x ø8 mm (Evolution Engine) or 3 x ø10 mm
(Mitsubishi Engine) securing bolts and washers.
Store these and the recoil system safely.
Removing the recoil starting system will give
access to the ø21 mm nut on the end of the
engine crankshaft.

ø21 mm
This nut can be held with a spark plug spanner
to prevent the crankshaft from rotating.
• Hold the crankshaft securely to prevent it
from rotating.
• Loosen the ø19 mm AF bolt on the opposite
end of the crankshaft by using a 19mm socket
with a tommy bar attached. The socket can
be 'pushed' into the machine to gain extra
security for the socket on the bolt head.
The ø19 mm bolt is tightened to a reasonably
high torque and may need to be 'shocked loose'
by subjecting the socket tommy bar to a sharp
blow (use a rubber mallet).
