hi, i dont think that is the answer i was expecting you are giving me clearences on conecting rod big end clearence and connecting rod radial clearernce,what i need is the standard size on the crankshaft and conecting rod so i know what over size bering i need to buy and how much the machine shop will remove on the crankshaft and rod side

sorry about that, the Polaris service manual does not give that spec. their manuals are very short on info.

 

I will opt out so another expert can help you

Connecting Rod: Polaris #3087016
Small end ID = 17.5 mm
Big end ID = 45 mm or 1.7716"
