    Removing Oil Pressure Regulator

    Does the engine have to be removed to replace OPR? I also notice there is not replacement part for the spring. Looks like it has to be purhcased as separate parts. Any one know if there is a "Kit"?

    This is from a BRP 2011 Technical file. Remove the engine for access and replace the individual parts as required with 2011 or newer parts. I simply ordered both of the newer springs and re-used the other parts and cap.

    I was think I may be able to pull the PTO off from inside the ski. But maybe it's easiler to remove the engine.

    I am sure you can do the job with the engine inside the ski, but it sure will be very messy and access will be difficult at best. I would use this opportunity to pull the engine completely, clean out the hull real well, replace engine mounts with Rhass mounts, pull the PTO housing inspect all the components, clean the oil pump screen, replace the OEM flywheel bolts with ARPs, remove the front scavenge pump housing and inspect parts and clean screen. Do a thorough realignment check and replace the drive line components as required. R&R the engine is really no big deal with the correct tools and shop manual.

    I recommend buying all the parts for the OPR, not just the dual springs. Sometimes the piston and cage can get dinged up from trash in the oil.....from bits of flywheel bolts and stator shavings or supercharger ball bearings/wheel pieces!

    Be sure to torque the cap screw and ensure the 0-ring is present.

    I intend on replacing the spring, cage, plunger and "O" ring. Just couldn't find the spring for the 2008. I'll look into the 2011 parts diagram.

    you have to drain everything and remove one side engine mount,drive shaft etc just to get the pto off and will make a huge mess so pull the motor its by far the easier cleaner way to do it.
    As above pay extra attention to the torque spec as over tightening will crush the regulator sleeve.
