Thread: Rusted Flywheel

  1. #1

    Rusted Flywheel

    End of last season my polaris 94 sl750 was hydro-locked. I got it started again and rode for a couple of weeks. When I tried starting it again this year it would not start. I can hear the solenoid clicking, but, the engine will not turn over. I removed the crankcase cover and found that the flywheel is pretty rusty. I pulled the spark plugs and could not turn the engine over by hand. I am no mechanic, but, would like to try and fix this myself. What are my next steps?

    sorry...

    I'd suggest becoming a mechanic quickly, even if you did manage to get the engine started again, the results wouldn't be pretty after a few hours.

    getting the engine out was a bit of a challenge for me and I had some idea of what I was supposed to do.

    Sounds like there is/was moisture inside the engine, and the crank shaft and/or bearings have rusted.

    How much money are you willing to put into repairing the engine?

    I paid. $1500 for it three years ago. Not sure what it is worth. What would it cost to have the engine rebuilt?

    Depends on who is doing the labor - yourself, or a shop?

    At shop labor rates, it probably is not worth the cost.

    You might want to check out the KBB used values on that model, just so you know what it might be worth in running condition.

    And have a look at what others have been asking for, and paying for, decent condition running SL 750 examples.

    Just for giggles, pull the pump first and make sure it's not locked up. It seems to me if it were running at the end of last season you should have warmed it up enough to rid yourself of the water...no quarantee but a remote possibility.
