Were can I get crankshaft seals and rings for my zip. It is in real good shape but the compression is only 90. It does not have spark but the other one I got has great spark. Thanks
Armed with a dial calipers, measure the shaft dia., housing bore and the width. Then, go shopping at your friendly, local, auto parts store. Or, your local industrial drive train supplier (bearings, belts, roller chain etc.)
Most are single lip with garter spring.
I learned to buy rings from 'the Greek' on evilbay. All you need is bore dia., width and end condition (if it requires notch for locator pin).
