Title: crank identfication
Post by: dem3500 on June 17, 2015, 09:16:54 AM

i searched and i could not find either of the numbers or letters on the crank. i had the engine apart so i decided to verify the crank.

I do not know what crank webs you have but I think the rod is a IMS/ Hot rod.  Why is there water drops on the crank and rod.  If those water drops are also in the needle bearings or main bearings the crank will be junk in a day or two.  You need to get the water out of the crank case immediately!!!!!!!!!

the water was from a dash through the rain into the shop. it was cleaned up right away
