    How to clean motor before assembly

    So I have all my pieces now and am ready to put the motor back together, Since there were some metal shavings at the bottom of the cases I want to clean everything internal before It goes back together. What is the best way to do this?? And what can I use that will not distroy the rubber seals on the crank. Right now I have 3 ideas, 1. Purchase a Harbor Freight parts washer and do it that way, 2. Use a large oil pan and alot of 2 stroke oil and just drench everything there is, 3. Find a shop that has a "Dish washer" type parts washer and see what they would charge to put everything into that. Do any of these sound like a way to go??

    Zep i.d red

    flyguytki, (see link)

    This stuff is incredible (ZEP I.D RED). We use at Carrier A/C for cleaning our chillers when overhauling them and cleans surfaces spotless.

    When I overhauled my 787 I used it and worked great, I also use it when rebuilding my carbs.

    I'll check my van, if I have a spare can I'll send it to you.

    Hope this helps.

    Kerosene or diesel makes a nice cleaner that is not overly flamable for safety.

    Is the bottom end split apart or still assembled??

    What can you use to remove black RTV? I've got that crap all over inside my block and it needs to come out. FYI, I didn't put it there... SBT did. They must use a whole tube of the crap on the crankcase of thier motors. Any thoughts on removing old gaskets?

    Use a cotton terry cloth rag. The roughness pulls the RTV right off. I use carb cleaner to clean and prep surfaces. It cleans better than brakeclean.

    I'll give that a try. The problem is that the black RTV is oil and gas resistant. I tried to clean it off in a parts washer, but it didn't work. I've tried carb cleaner too with no luck.

    Use no cleaner. Just the rag, or a wire brush on the rough cast areas. And the rag on the machined smooth mating surfaces.
