Supporting Member texscottyd Posted April 1, 2020 Supporting Member Share Posted April 1, 2020 Yes, 30mm. I just checked the part number on the GT, and it's the same as the replacement nut I bought for my 2015 FJ: 90179-22018-00 1 Link to comment Share on other sites More sharing options...
Clicknow Posted April 2, 2020 Author Share Posted April 2, 2020 Hi, is it the right thing to do and add copper grease to the sprocket nut,thread regards graham Link to comment Share on other sites More sharing options...
BBB Posted April 2, 2020 Share Posted April 2, 2020 I don’t think it’s needed there @Clicknow. It’s not in a weather exposed area, you won’t be taking it off very regularly and it actually affects the torque tightening value. Not a problem if you want to, but no need either. 1 Red 2015 Tracer, UK spec (well, it was until I started messing with it...) Link to comment Share on other sites More sharing options...
johnmark101 Posted April 2, 2020 Share Posted April 2, 2020 I would think that adding grease to any fastener would affect the torque value. With lubricant in place the nut would turn past the point where it would normally reach torque and run the risk of damaging or stripping threads. 1 There is nothing like spending a day riding with friends in the grip of a shared obsession.

That nut is staked and really should not be reused. Yamaha also calls for loctite on it, IIRC. -Skip 1 Link to comment Share on other sites More sharing options...

I didn’t even need a wrench, and just spun the nut off by hand... yikes! Definitely use a new nut. It’s cheap and safe insurance. Here’s how mine looked directly off the bike... no way to even consider reusing that one. 3 Link to comment Share on other sites More sharing options...

Down the road you won't need a puller to get the sprocket off. 1 He who dies with the most toys wins. Link to comment Share on other sites More sharing options...
Clicknow Posted April 3, 2020 Author Share Posted April 3, 2020 Hi can't seem to find the torque specs for the front sprocket nut,rear axle nut and rear sprocket nuts on my (GT,)would someone kindly point me in the right direction many thanks graham Link to comment Share on other sites More sharing options...
Supporting Member roadrash83 Posted April 3, 2020 Supporting Member Share Posted April 3, 2020 @Clicknow the front sprocket torque is 95N.m 70 lb-ft. 1 He who dies with the most toys wins. Link to comment Share on other sites More sharing options...
Clicknow Posted April 4, 2020 Author Share Posted April 4, 2020 Hi, the manual says the rear axle nut should be torque to 150Nm or 111lb-ft wow ! That is freking tight IMO. I have torque my GT to 95Nm-70lb-ft anyone any thoughts on this? regards graham 1 Link to comment Share on other sites More sharing options...
Supporting Member roadrash83 Posted April 4, 2020 Supporting Member Share Posted April 4, 2020 70-80lb-ft should be fine. 1 He who dies with the most toys wins. Link to comment Share on other sites More sharing options...

Like a lot of things in the manual - DISREGARD and use common sense instead. I have never used a torque wrench on the axle nut. 4 ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...

That is freking tight IMO. I have torque my GT to 95Nm-70lb-ft anyone any thoughts on this? regards graham I also find this to be quite a bit of torque. I always use a torque wrench when tightening fasteners when a torque value is available. But, 111 foot pounds is a lot for an axle nut. I worked in QC for a major auto maker for 28 years and there is a lot of thought and science that goes into determining a torque value for a given fastener. But to be honest, I set my wrench at 95 foot pounds for the rear axle nut and call it good.
