With a dremel and a good quality scale you could balance them yourself.

They soak for close to a week until my new fav tool arrived. I got a great deal on a craftsman vintage stud puller. Several gave a sharp “CRACK” as the vintage tool over powered them. Others gave in without a fight, like a Lake Erie walleye. I almost bought the 38$ unknown brand from APE until I shopped evilbay and found the craftsman tool. $15 shipped and had it in 3 days. Worked 13 1/2 hour every day this week, quite tuckered. Tomorrow I’ll get them packed up and off to Vapor Hone Saturday.

Interesting tool. I think the studs are loctited in. Heat might be an alternative.

Worked great. I was able to grab the stub right at the case so twist was completely eliminated. The hardest part was getting the tool to release the stud. I quickly figured out that leaving the stud still a few threads in the case and then grab the stud with a vise grip allowing me to reverse the rotation will holding the stud and the tool released.

True or not I was advised not to heat. Success nunthless.

Open flame not so much, heat gun no problem. Trick with a heat gun is to attack the part quickly after heating it up before the heat dissipates. Good heat guns are a blessing few use. Glad yours worked out Mikaw. Just shows how nice it is to be able to find old tools.

You mentioned Loctite Matt, i've never used locking agent on studs. Maybe some Yamabond or equiv. on the LONG center 4, just a bit on threads. These "can " weep oil because the threaded bore is open to the inside of crankcase.

There was no locking agent on the studs from the factory, what was done after that is anybodies guess. I do seem to remember a service bulletin concerning oil leakage at the base gasket that recommended Kawabond on the threads of the studs that went through into the crankcase. Nice purchase of an "old school tool" Matt!

Looks like I was wrong on the loctite. But I've spent hours cleaning grit out of the area between the stud and the hole, and I came to the conclusion that at least some of them had some very hard material placed in there, presumably at the time of installation.

I have a question for krazee....when the engines arrived on the shop floor were the studs already installed?
