Thread: 80" scraper

  1. #1

    Default 80" scraper

    I have a 1945 set of chief cases with t&o 80" flywheels. Question: has anyone done this type of set up and what did you use for a flywheel scraper or oil pickup? Thanks

    You can modify your cases to accept the 47 scraper.Cases must be notched out to fit,or can run the stock earlier pick up tube sump valve set up but not as good as the 47 scraper.(at least the factory seemed to think so)

    Doesn't the factory scraper hit the flywheels though?

    No, .010" clearance, skimming, not scraping.

    Right I just thought because the flywheels we're bigger it would actually hit on the scraper and I thought they were made out of aluminum so they couldn't be bent,is that right?

    The factory 80 and 74 wheels are the same diameter.The scraper is steel,and doesnt need to be nor do you want to bend it.
    All your work will be to modify cases.

    T&O should bolt in to your cases.
