marcusk Posted December 18, 2021 Share Posted December 18, 2021 Hi! How would I go about finding the torque for the rear wheel axle/nuts of my GSR 750? I recently bought a secondhand 2014 model and I need to adjust the chain tension and rear wheel alignment and it didn't come with a manual. I can't find anything online either or any Haynes manuals... Also, for ref, is the newer GSR-S750 principally the same bike as I am sure there wil be more info on that around?

Mississippi Bullfrog Posted December 18, 2021 Share Posted December 18, 2021 I usually just use an 18 inch breaker bar with the socket and turn it by hand until it's firm. Quote Link to comment Share on other sites More sharing options...

Bianco2564 Posted December 18, 2021 Share Posted December 18, 2021 Ring a dealer? On various cars I've had when I didn't know the front hub nut torque, I'd centre punch the end of the driveshaft and the nut inline with each other and aslong as I'd didn't change any parts, just retighten the nut until the marks lined up again. Obviously this assumes it was right in the first place but if it had been running ok, fair to say it wasn't far out. 1 Quote Link to comment Share on other sites More sharing options...

Keeper96 Posted December 20, 2021 Share Posted December 20, 2021 Tighten it till it goes loose then back it off half a turn is a good guideline… Quote Link to comment Share on other sites More sharing options...
husoi Posted December 20, 2021 Share Posted December 20, 2021 A torque wrench (TW) should be part of the must have tools for a biker that does his/hers own servicing/repairs. You can get all sorts of TW both digital or the traditional ones with prices from around £25 up to your annual salary torque wrench digital torque wrench Make sure you get the wrench(s) that cover the toque range for your bike. Usually something 2 - 200 nm should be good enough but check with your service manual. Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted December 20, 2021 Share Posted December 20, 2021 I prefer to use different torque wrenches for different ranges. I'm never happy using the same one for doing up crankshaft pulley bolts and camshaft journal bolts. So I have one for the lower range and one for the higher range. 2 Quote Link to comment Share on other sites More sharing options...

But which do you use for the middle range? Quote Link to comment Share on other sites More sharing options...
husoi Posted December 20, 2021 Share Posted December 20, 2021 Traditional spring load TW have always been limited to the short range which means doing as you do @Mississippi Bullfrog Newer digital TW have a different method for applying the torque allowing the range to be extended. About quality and reliability I can't say about the new digital ones while "old school" ones have more than proof their worth. Again, you will get what you're paying for, so do not to expect much from a £30 TW Quote Link to comment Share on other sites More sharing options...
marcusk Posted December 21, 2021 Author Share Posted December 21, 2021 Cool, thanks all! ta for the link to the user manaul (my bike didn't come with one) plus I mananged to find an old service manual on Ebay, so all the smaller torques should be in there. I I have a good 'old school' Clarke TW wrench up to 200nm but only have a super small TW for my (push)bike mechanicals, that only goes up to 15nm, so not much good on a motorbike Quote Link to comment Share on other sites More sharing options...
