Careless Posted December 15, 2008 Share Posted December 15, 2008 anyone know which flywheel bolts to use? I can't find the ARP number as I don't have the internet at home and can't do a thorough search. I measured the stock VG30ET bolts at 24mm, and the VG33 bolts at 17mm (parts guy measured the ones in stock). I think I need them somewhere between 17 and 19 mm anyways, so I ordered the VG33 ones. I hope they's ok. 47 Bucks Quote Link to comment Share on other sites More sharing options...
260DET Posted December 15, 2008 Share Posted December 15, 2008 Sorry can't help but you don't need me to tell you that the fit and length of such bolts is critical. ARP may not do them anyway, the (Nissan) ones for the VG30DET looked to have a special fine thread. Quote Link to comment Share on other sites More sharing options...
Careless Posted December 16, 2008 Author Share Posted December 16, 2008 ARP carries pressure plate bolts in their "pro" series that are a UHL of just over 20mm, somewhere in between 20 and 21mm shank + thread. they are 10 x 1.0 fine thread. I'll be getting the VG33 bolts tonight, and they seem like they would work. if there is a thread or 2 less of engagement than the standard bolts, I will not be concerned. I'll friggen JB WELD Those bolts in there if it gotta!!!! LOL (just kidding) Quote Link to comment Share on other sites More sharing options...
Careless Posted December 17, 2008 Author Share Posted December 17, 2008 Summuna Onion! the VG33 bolts were waaay too short. I brought my flywheel with me to the dealership. The ordered two of the wrong bolts anyways, of which were the ones I currently have that are too long. the VG33 bolts only get about 3 threads out the back of the flywheel. Is it possible that the two VG30ET Turbo trans models came with different flywheel bosses? 240 vs. 250mm clutch packs = different flywheel bolt lengths??

260DET Posted December 17, 2008 Share Posted December 17, 2008 VG30DE/TT flywheel bolts are M10 fine thread. I had to buy a set from Nissan, they are expensive and from memory, thats from more than a year ago, ~30mm long. Alternatively, what do Fidanza say?

Careless Posted December 18, 2008 Author Share Posted December 18, 2008 LESSON LEARNED check threads for left over thread locker. By chance, the two bolt holes that I threaded into just to test were packed with old threadlocker. I took an old bolt and cut slits into it and threaded it back and forth with a power-screwdriver (low power @ 4v), and worked it in and out with some brake clean (whipe your main seal thoroughly if your brake clean is chlorinated). The bolts then completely threaded through. There was so much thread locker coming out that it felt like the bolts bottomed out, but they didnt. The flywheel is not balanced but I don't have the time to do that now, seeing as everyone around my hood doesn't balance stuff like this or tell me it's "not worth it", which is basically "nah, i dont wanna touch your shiney flywheel". I can't send it out, it will take too long. I'll cross my fingers that fidanza is under 8-10 grams imbalance. As for the bolts, the stockers were fine. Torqued them to 80 ftlbs with some red loctite. The small pack of green loctite gel that was supplied was definately not sufficient enough for even one bolt. they were probably for the dowel pins. Go figure! Man I feel like an idiot. I could have had the car running! V33 bolts are roughly 17mm VG30ET Z31 bolts are roughly 24mm VG30DETT Z32 bolts are rouhgly 27mm All are measured as UHL (under head length) Thanks for keeping me company in the thread, 260DET Quote Link to comment Share on other sites More sharing options...
emaster Posted April 1, 2009 Share Posted April 1, 2009 Where do I get some of these? Do they usually come with the flywheel? Quote Link to comment Share on other sites More sharing options...
Careless Posted April 1, 2009 Author Share Posted April 1, 2009 FALSE ALARM the bolts were fine. I ran a rethreader through the entire bolt hole and found that since they were fine thread, the thread locker was very very thick and encrusted inside the bolt hole. I ended up heating it up with a heat gun and go back and forth with an old flywheel bolt that I had cut at an angle with slits into a sort of cleaner, as the rethreader wasn't doing much. you can order some stock bolts for the exact car your engine came from and use those. I felt kinda stupid. Quote Link to comment Share on other sites More sharing options...
