bowcop Posted February 12, 2008 Share Posted February 12, 2008 Last night I took off my rear tire to just see how it was done, never having tinkered with it before....It was a bit of a struggle to line the bolts back up for putting it back on. My question is....Is there anyway to screw this up? I have not ridden it since I put it back on. Forgive my ignorance on this! Link to comment
GordonB Posted February 13, 2008 Share Posted February 13, 2008 The big issue is to pretorque in a criss cross pattern per your riders manual, then do a full torque criss cross pattern. Do not fully torque on the first go around! And no lube or anti sieze on the bolts! Link to comment
bowcop Posted February 13, 2008 Author Share Posted February 13, 2008 I did do the criss cross tightning, and them all 4 in a circle.....It seemed to spin ok.......Should I go for a quick test ride before embarking on a long ride? Link to comment
Jeff from Massachusetts Posted February 13, 2008 Share Posted February 13, 2008 If you torqued the clean bolts you are good to go. Link to comment
Mr. Frank Posted February 13, 2008 Share Posted February 13, 2008 Everything is supposed to be clean and dry before you put it all back together -- bolts, spacer, wheel mating surface. Be sure to use proper torque. Link to comment
bowcop Posted February 13, 2008 Author Share Posted February 13, 2008 I just used the air gun to torque them down....is this bad? Before I ride........Please advise! Link to comment
Jeff from Massachusetts Posted February 13, 2008 Share Posted February 13, 2008 I just used the air gun to torque them down....is this bad? Before I ride........Please advise! Your BMW has many aluminum parts that will strip if over tightened. If you plan to do work on your bike go out and get a Haynes or Chalmers repair manual. When we all said that you need to torque your lug bolts, what we mean is that there is a specific torque settings. For example on my 2000 R1100RT the torque settings are to tighten rear wheel bolts initially to 50 NM (nanometers) or 37 foot-pounds then tighten again to 105 nm (77 foot-pounds) This is done with a torque wrench. I would say the rear wheel bolts are forgiving and you most likely did not do any damage but you should loosen the bolts and torque them correctly Link to comment
bowcop Posted February 13, 2008 Author Share Posted February 13, 2008 Thanks Jeff, I need to buy a tourqe wrench....... Link to comment
Mr. Frank Posted February 13, 2008 Share Posted February 13, 2008 For that application a beam style torque wrench works well. Link to comment
GordonB Posted February 13, 2008 Share Posted February 13, 2008 I did do the criss cross tightning, and them all 4 in a circle. Just be sure you did the preload/torque first (I beleive around 40ftlbs,, then you torqed them to full value (I'm guessing....70+ ftlbs) Link to comment
AndyS Posted February 13, 2008 Share Posted February 13, 2008 I just used the air gun to torque them down....is this bad? Before I ride........Please advise! Yes, very easy to apply way too much torque (or too little). I personally would loosen them and retorque using a torque wrench (I use a beam type cos they are hold their accuracy for longer and with more abuse). Andy Link to comment
AviP Posted February 13, 2008 Share Posted February 13, 2008 My question is....Is there anyway to screw this up? Not unless you are a total dork when it comes to wrenching. Just follow the star (criss-cross) pattern for torquing this wheel (or any car wheel) to the spec and you should be fine. Link to comment
BFG Posted February 13, 2008 Share Posted February 13, 2008 ...tighten rear wheel bolts initially to 50 NM (nanometers) I believe that's newton meters. You'd need an awful small torque wrench to apply one billionth of a meter! Link to comment
Jeff from Massachusetts Posted February 13, 2008 Share Posted February 13, 2008 Right Newton meters for lug bolts nano meters for windshield mounting screws. Link to comment

Wooster Posted February 14, 2008 Share Posted February 14, 2008 bowcop, As you may surmise, using an air wrench to "torque down" any bolt (rear wheel, for example) may save time and energy yet does nothing to the cause of "application of a specific torque value, e.g., 75 ft lbs" to the fastener. I strongly recommend chucking the air wrench and its chuck and employing an actual torque wrench when "torquing down" a fastener; only in this manner will you confidently apply the specific torque value.
