Disassembly - Sea-doo RX Shop Manual

MAINTENANCE
There are no wear parts anywhere in the system
and there are no adjustments to be periodically
checked. The only possible maintenance required
would be cleaning of carbon deposits from the
guillotine slide. Cleaning intervals would depend
upon the vehicle usage. We would suggest annual
cleaning of the valve. If a customer uses a lower
quality oil, more frequent cleaning may be re-
quired.
No special solvents or cleaners are required when
cleaning the valve.
BORING PRECAUTION
In its stock configuration the RAVE valve guillotine
has a minimum of 0.5 mm (.020 in) clearance to
the cylinder bore measured at the center line of
the cylinder. This is the minimum production clear-
ance.
There is only a first oversize piston available for the
947 engines. That piston is 0.25 mm (.010 in) larg-
er in diameter than the stock piston. When the
oversize is installed, the guillotine will have a min-
imum clearance of 0.375 mm (.015 in) with the
cylinder bore. This is the minimum operating clear-
ance the guillotine should be used with. Clearance
less than 0.375 mm (.015 in) will require reworking
of the guillotine to achieve the proper clearance
and radius.
