Cam nuts & Studs

[pathfinder]

You know I should never buy cheap tools. I bought an inch lb torque wrench. Set it to 7.5 to tighten the cam caps and thought I was putting more than 7.5 inch lb's. Felt like about 30 inch lb's to me. Anyway stripped 2 nuts and 2 studs before I thru the damn thing in the trash. Any hint on where to get studs and nuts and the BEST Tool to remove the bad studs? As you may have noticed I'm not having a good day. This entire rebuild has gone real well up to this point. Guess I had to run out of luck sometime.

Pathfinder, usually the studs are removed by placing two nuts onto the stud and tightening them to each other. You can then back the stud out of the head by turning the BOTTOM nut counter-clockwise.

I have a head sitting in my office right now that I just stripped the valves out of, for someone else on the list.
I can remove some studs for you, if that would help.

Let me know hoe many you think that you will need.
You can PM me with an address.

That usually works, but some are harder to get out than others. If the stud is trashed, you may not be able to get two nuts on it (this is getting kind of "Freudian"). But there might be enough threaded portion left near the top to do this technique. There is a tool called a stud extractor that I haven't ever used. I have removed them with a good visegrip.

I have a stud extractor. It works like a pipe wrench in that it tightens harder on the shaft the harder you pull. Mine is rather large as it is for automotive head studs. I can't see it working on the cam studs. Smaller virg....versions should be available

This might be a good place to weld on a nut if there's not enough threads left for the double-nut trick.

Hey Dave/Pathfinder,

As for the torque wrench, the setting should be 7.2 foot/lbs for the cam nuts. That would translate into 86~87inch lbs!?

Anyways, I used a standard flex rod gauge type, but smaller in the range, 0-75 ft/lbs, got it from Sears a few years back, about $25.00 or so IIRC.

Sorry for your bad luck, BTDT with my rebuild, had 2 bent valves found only after torqueing the head bolts and timing the cams! DOH!
