loopchaser Posted May 12 Share Posted May 12 Hello Everyone I'm new and happy to be here. So I stripped the bolt holes torquing down my tensioner on my 97 legacy to 20 ft/lb(the one where the piston is separate from the pulley). Later I found out that the top end of the torque specs are 19.5... silly me. Im trying to figure out the bolt size to match up with a helicoil. I believe the part number for the bolt is 010508220, but cant find the size specs. Does anyone know? PS - I also just ordered the bracket it attaches to in case the helicoil fails... Thanks everyone, Loop Link to comment Share on other sites More sharing options...
lmdew Posted May 13 Share Posted May 13 12mm bolt. I've used longer ones as well. Ace will have them, just take the old one and match it, but longer. Link to comment Share on other sites More sharing options...
loopchaser Posted May 13 Author Share Posted May 13 Ah I didn't think about using a longer bolt... Thanks! Link to comment Share on other sites More sharing options...
lmdew Posted May 13 Share Posted May 13 If you have a tap, run it in to clean the threads. If you don't have a tap, make you own by cutting a groves down the threads from head to end of the bolt. Grinder, file, hacksaw. Link to comment Share on other sites More sharing options...
el_freddo Posted May 17 Share Posted May 17 Are these the block threads that the three bolts hold the bracket on to the block or the bracket threads that hold the tensioner piston to the bracket? If it’s the tensioner piston bolts to bracket thread that’s the issue try and get another bracket. Failing that get a bracket for the “newer” tensioner (which is said to be inferior but is used on all EJ engines since the mid to late ‘90’s so parts are plentiful) and run that newer style tensioner. If it’s the threads in the block a helicoil would be the way to go. Mind you, I can’t see how .5 of a foot pound would strip your threads out, I get the sarcasm side of things, but if your torque wrench was set and operating properly those threads must have copped some previous abuse, or you seriously over tensioned the bolt(s). How many are we talking about that need replacing anyway? Another thing to consider is that a cooked block from over heating will have softer metal meaning softer threads as a result. There may be other signs of serious overheating such as melted looking rear cam cover parts. Cheers Bennie Link to comment Share on other sites More sharing options...
nelstomlinson Posted May 19 Share Posted May 19 Which tensioner? We just did the timing belt on a '95 EJ22, and had to get a Helicoil set for M10x1.24 for a stripped bolt hole. I believe it was the bolt holding a pulley, not the one for the tensioner. Anyway, if you have the bolt, just carry it into the hardware store and find a nut that fits it, then you'll know the size. Get a Helicoil kit, fix the hole right, and it's better than new. Link to comment Share on other sites More sharing options...
loopchaser Posted May 22 Author Share Posted May 22 Thanks everyone. I just discovered the new iteration of the bracket involves a few different mounting screws that I need to get, along with the newer tensioner style. I tried to helicoil the stripped holes and did not execute it properly... so now im looking for the discontinued part (13086AA012). This engine is in pretty decent shape from what I can tell, has never overheated when ive had it. But I believe you are right, el_freddo that the threads had previously taken a beating. Its the 2 tensioner (not pulley) bolt holes that got stripped. Long story about the failed helicoils... ill spare you the details. Anyhow the dealership didnt seem to understand how to make the new bracket work for this car so I believe Im just going to pursue finding the discontinued part, if that doesn't work Ill look to "modernize". Thanks any tips on this part would be much appreciated. 1 Link to comment Share on other sites More sharing options...
lmdew Posted May 23 Share Posted May 23 www.car-part.com ebay.com I most likely have one in Colorado, but I'm in Hawaii. So it goes. Link to comment Share on other sites More sharing options...
lmdew Posted May 23 Share Posted May 23 You could have them welded up and then retap as well but a good used is the way to go. 1 Link to comment Share on other sites More sharing options...
