Starter Torque Specs.
Hey does any of ya'll know what I should torque my starter attachment bolts to. I have a 1989 5.8 351 Windsor 4x4. The Haynes manual says to tighten them "securely". The reason I ask is because I guess I don't know how "secure" securely really is and I ended up overtightening them and stripping out the threads. So now I have tapped in threads one size bigger and was just wondering if any of ya'll could give me a good torque spec. Thanks guys!

Geez, what did you use to tighten it down: 1/2" drive impact? I tighten them with a 3/8" drive ratchet. When it is snugged down I'm done. I found a torque spec of 15-20 lb. ft. One other thing is that I probably would have repaired the threads with a Helicoil and not a bigger bolt. Have you checked to make sure the larger bolt will fit through the starter?

Well I only stripped out the threads on one bolt so what I'm going to do is drill the hole out and put a bolt through there with a nut on the back of it. Luckily though, there is room for a nut on the back. Do you think this is a good idea? And yea a bigger bolt wont work. I haven't tapped the threads out yet for a bigger bolt I just drilled out the existing threads.

They make some neat thread repair options. Either helicoils or thread inserts. The insert might be better in this situation.

Don't have to worry about them coming apart like a heli coil could from repeated use. I've used them in alum transmission cases.
