Well i am getting ready to fully assemble my rebuilt 225 (bored .060 over). It has been sitting in pieces in my garage and basement room for a while, and i have noticed a thing or two: 1) The crank shaft has a bit of surface corosion on the smooth journals, I need to get rid of this before I install the crank correct? What is the best way to do this, and how do I store the crank until it is time to install it? 2) Uhhh errr, I guess there was only one issue, sorry. Help me out please. I was thinking a fine steel wool and some warm soap and water, then dry thoroughly and rub the journals with motor oil, and then bag it in a trash bag until I drop it in the engine. THe crank is not outside or even in the garage, so I didnt think to keep it in a box or bag. I apologize to the Mopar Gods. Gonna have to sacrifice me some tires. Caesar |

A good scrubbing with detergent and hot water to start, blow dry and spray with wd-40 or whatever you like to use instead. Then dry the journals with acetone, brake cleaner, carb spray etc. You can then polish them with 400 or 600 wet or dry paper. Cut the paper in strips to fit each journal, wrap each journal with one and tape them. Then you use a 1/4" piece of cord wrapped once around the journal to spin the paper by pulling back and fourth on the ends of the cord. Cotton sash cord will work better than nylon. It takes a little practice and you need to make sure the crank stays on the bench. Pulling up and down rather than towards yourself is safer. Count the strokes on the first one and check it after the paper starts to spin easy, about twenty strokes at the most. This is an old school way to do this but works very well. You need to clean and oil the crank again to get any grit off when done. Don't try to use the paper by hand otherwise, it won't turn out right. The alternative is to have a shop do it on a machine. |
