Re: Micro Welding of bearing shell to rod housing bore
OK, I have no personal experience with this problem. But have talked with someone who I believe had a similar problem. He modified his rod bearings to give a little more clearance in just that area and that seemed to fix his problem.

Re: Micro Welding of bearing shell to rod housing bore
I have never had this problem. A long shot. Do you have your negative cable attached directly to the block? Ray

Re: Micro Welding of bearing shell to rod housing bore
Yes Ray the cable is connected to the block. I never considered an arcing or plating situation
Not sure on cycles on rods or bolts. Bolts are ARP 7/16 20NF 12 point. The big end of the rod stays rounder longer since we installed a clean neutral valve body in the trans. I use the brakes to stop the car without compression braking. Last edited by Larry Hill; 08-22-2021 at 07:27 PM. |

Re: Micro Welding of bearing shell to rod housing bore
Larry,
The design of the bearing is important. The size of the rod bore determines crush. You may need a bearing with more ellipse or a slightly thicker oil for the .003 clearance. It is a long read, but Mahle has a good read on bearings. All bearings are not created equal! https://www.speedperf6rmanc3.com/con...20Bearings.pdf

Re: Micro Welding of bearing shell to rod housing bore
Glenn I cant find the info on bolts or rods. Bolt stretch is .0055.
I need to finish my engine to race BG this weekend so my response time will be long until we are at BG. Thanks everyone for the help and input. |
