A couple of weeks ago I installed my rebuilt motor. I bought motor mounts from Ames, these were the mity mounts. I tightened them down to around what I thought was snug. I sent an email to the tech-support at the engine mount company, and they said 40 to 50 pounds was sufficient torque. Today I went back to snug them up, and the passenger side spun. I removed the bolt and saw that the threads were a little messed up. I do remember hand threading it in but the butchering of the threads was more than a couple turns up, and this I missed during assembly. I’m not sure if I should run a tap over the bolt and insert a tap into the mount to clean up the threads on each, or just tap it to a bigger bolt. The original bolt was 1/2†x 1 1/8-20. I know I can change the mount, but this would involve me getting an engine hoist back after I returned it. Is it recommended to change The entire bolt, or re-tap with old bolt and threads in mount, or order a new mount? I’m not sure how much stress these bolts that connect the frame and the mount receive.
