Re: RD-17 crank defects—-

Thank you 20merc-
My phone is pretty bad a taking pics- not good resolution…..
The pits are more or less scattered all the way round- but they are only about 2 mm at most. I have not yet cleaned it up yet to see how much
it might clear up- but i will need new needles for sure. The needles have very tiny stripes of pitts- about 1/3 of them. so they need
replacing. I looked again at the lower rod to crank- I can "tip" the piston about 3/16 but I really cant feel any slop " IN-LINE" with the rod.
i am wondering if the slop in the flywheel I could feel might have been comming from the mains on the crank. The crank pins look pretty
good. The lower of the 3 mains is the only one showing pitts.
I will try putting it in the lathe and use some abrasive paper on the pitted area and see if it improves any.
