I am putting in a new five lobe Milodon pump body, which is aluminum, with an aluminum cover. I thought i read that is easy to over torque the bolts, and bind up or seize the pump? What should this combo be torqued to? Thanks in advance!!

The spec is 30 ft lbs. but I have heard of people having binding problems on some pumps, so after you torque it down stick your priming rod in there and turn it over to make sure it feels fine.

If you really want to know where you are at, torque the pump down to 5 lbs, then put a dial or beam type torque wrench on the priming shaft and get a baseline, then torque down the pump and recheck the priming shaft.

Thanks, will call Tom. I have time anyway, the new pump body takes a longer distributor/oilpump drive shaft. Its on the way, hope to run on Saturday, provided i figure out why #3 isn't firing!
