Guest Posted December 20, 2004 Share Posted December 20, 2004 Well thank you auto zone for the 2nd torque wrench that was broken. My friend I was showing how-to do this with, was doin what he was instructed while I was on the phone. In doing so the defective torque wrench wayyyyyyyyy wayyyyyyy to much by far over torqued the bolts on the side mounted seperator plate or force plate whatever you guys perfer to call it. It took the heads right off 2 bolts and stripped the housing of a few others. I was able to use a chizzle and get the 2 bolts out but I am so unclear what 2 do next with this. Re-tap or re-thread whatever I dunno please instruct. 2nd would be my pan i stupidly left off and my friend came over and picked it up thinkin I was talkin about that one yada yada. Long story short the tranny hasn't had a pan on it for 2-3 days, the valve body is not on and is safe, will dust and or moisture be a problem? And how do I resolve this before I destroy my $$$ tranny Quote Link to comment Share on other sites More sharing options...
alex's72fgmc Posted December 20, 2004 Share Posted December 20, 2004 OUCH, well with the threads chase them with a thread chasing kit. the ones that are stripped out you might be able to rethread the next size up and helicoil them with a helicoil set. Take back that pos torque wrench and have them test the torque wrench "they should have a machine to do that with at the store you bought it from" if it fails the test demand a new one "and if the rethreading/helicoils dont work out then demand a new transmission from them" or have them pay for a machine shop to weld up and rethread the holes. now of course i would have stopped after the first one broke and thought something aint right with it. j/k Quote Link to comment Share on other sites More sharing options...
Rob Peters Posted December 21, 2004 Share Posted December 21, 2004 OUCH, now of course i would have stopped after the first one broke and thought something aint right with it. j/k I was thinking the same thing. After one of them I would have considered having the torque wrench checked for accuracy. I don't think they will pay for the damage. They would more than likely tell you to contact the manufacturer of the wrench Rob Quote Link to comment Share on other sites More sharing options...
wallaby Posted December 21, 2004 Share Posted December 21, 2004 I just had a thought. I believe all the trans fasteners are torqued in INCH POUNDS. If you tried to torque them in FOOT POUNDS that would explain why the fasteners broke. Double check those torque values, it may not be the fault of the wrench.

alex's72fgmc Posted December 21, 2004 Share Posted December 21, 2004 I would seriously hound autozone for it. its the second one you got that was bad they should have better quality control than that. push the issue with the store or regional manager. dont settle till you get what you want. alex oh and wallaby has a good point was it inch or foot lbs? trans bolts are in inch pounds "well for my 4L60e in my truck 80-120 inch lbs = 6-10 ft lbs" Quote Link to comment Share on other sites More sharing options...
OutLaw !!! Posted December 21, 2004 Share Posted December 21, 2004 Mark the new transmissions are in.lbs. The specks for the older transmissions should be 12 ft.lbs & 8 ft.lbs for a powerglide. That is right form the shop manual.Hope this helps. Roman!!! Quote Link to comment Share on other sites More sharing options...
Guest Posted December 21, 2004 Share Posted December 21, 2004 You could always drill a slightly larger hole and then put a 3/8 thread size. You would have to enlarge the pan hole that size as well. Remember when running a tap the hole must be slighty smaller that the tap size I just used a garbage bag and put some holes in it and "bolted" it to the tranny. It should protect your valve body etc. Quote Link to comment Share on other sites More sharing options...
AndyBill402 Posted February 25, 2005 Share Posted February 25, 2005 On the bunged out bolt holes, you can get a heli-coil kit at ACE and put the exact same size bolt back in. That's because the hole is drilled and tapped for the heli-coil. an original size bolt then screws into the heli-coil. The fix will be stronger than the original metal if you do it right. As for the torque wrench, here's a suggestion. Don't use one on your tranny pan. It's not necessary. Using a socket wrench, put your hand on the wrench up close to the socket and, using your wrist only, tighten the bolts in a criss-cross fashion. If you use the right gasket, it won't leak, you'll get done in time for diner, and you won't ever break a bolt. On items that do require a torque wrench, I use the old pointer kind. It lasts forever, and never goes out of adjustment. I have a clicker torque wrench, but I'm afraid to use it, although I would use it if I had an easy way of checking it.

Guest Posted February 25, 2005 Share Posted February 25, 2005 Andy, Check your clicker using the pointer torque wrench. Torque a bolt to say 30 lbs. with the pointer and then set the clicker to 30 lbs. and it should click right off or very close if it's correct. I've never tried this but the idea just came to mind. Worth a try. Quote Link to comment Share on other sites More sharing options...

I sencond that!!"It could have been the torque wrench operator" Or you could just apply "Alabama torque". Quote Link to comment Share on other sites More sharing options...
AndyBill402 Posted February 27, 2005 Share Posted February 27, 2005 Mo, Your idea of checking the clicker torque wrench might just be brilliant. The next time I install some cylinder heads, I'll try your trick. I don't see any reason it shouldn't work. Thanks, Andrew Offutt Quote Link to comment Share on other sites More sharing options...
