I need to dismantle one of my rims and rebuild it. Where do I find the correct torque settings for the nuts?
BBS RM bolt torque is 12-15 lb/ft BBS RS bolt torque is 40 lb/ft NOTE: Some people have reported that when re-using old wheel bolts that they have experienced breakage to the bolt at 40 lb/ft torque specs. This number was provided by BBS for new and unstretched OEM bolts. Some individuals have suggested that 18 lb/ft is a more reasonable torque setting when re-using old bolts on BBS 3-piece wheels. Use these numbers at YOUR OWN RISK. <?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /> Disassembly and Assembly information: Taking apart your wheels is a piece of cake. It only requires common sense and a little patience. We have yet to have anyone that hasn't been able to do it on their own. It is important to make sure that the parts are clean when they are reassembled. <B style="mso-bidi-font-weight: normal">Warning: - before splitting the wheels, spray wd40 into the thread holes at the rear of the BBS rm wheels, or if BBS rs onto the nuts.[/B] <B style="mso-bidi-font-weight: normal">You snap a BBS rm stud its a nightmare to sort.[/B] Use a 12pt 8mm socket on the bolts and heat the lips up with a heat gun for 5-10 minutes before going at them with a rubber mallet. It should take no longer than 2 hours to have them all apart. Use a decent 3/8 drive torque wrench and use a crossover method for tightening. After you torque the wheels put a bead of silicone adhesive over the seal and smooth it out. If you are really worried about leaking just put a very thin coat on one day and follow it up with a second coat 24 hours later. Sealing Wheel Shells: 1. clean the mating surfaces with lacquer thinner and let dry. 2. Bolt the two shells together "DRY" and torque to spec. and leave to settle for a few hours, re check torque setting. 3. Lay thin bead of silicone in the crack between the mating surfaces and smooth. Let it dry overnight. 4. Re-apply a bead over the first and smooth out to about a 1.0" bead width and smooth. If you follow this procedure your wheels will never leak. The reason you don't want silicone between the halves is because all silicone shrinks as it cures. As is shrinks the pressure between the shells changes and your torque changes. BBS use a different system. I wouldnt worry about how the silicone looks. Once you put a tire on you cant see it anyway. The last thing to want is to be driving down the road and get a flat because you didnt use enough sealant. Use a good quality silicone sealer, about 5 a tude. Torque settings BBS RM bolt torque is 12-15 lb/ft BBS RS bolt torque is 40 lb/ft We advise the use of new studs etc when refurbing splits, in all cases we offer to chrome or 18k plate the original studs as long as they are in serviceable condition. But Schmidt do aftermarket ones and they are good quality. Have been polishing on and off for the past 20 years or so, but only really got right into it in the last 5 years. Mostly the polishing side is very very time consuming as we go all the way to 50000 micro grit, this gives a finish of chrome and the finish is absolutely flawless as is no marks what so ever, but as I said it takes ages, about a full two weeks per set of 4 wheels, but thats the whole wheel, front, rear and through the windows and at 1000 per set its not everyones cup of tea. We use a hub to clamp the wheels onto and a motor spins them up to about 2500 rpm and we go through the stages that way and then onto the polisher for finishing off. cheers mike
