Yamaha TRX850 Enthusiasts Forum

Thought it about time I said hello as I joined some months ago and, while I've been 'on' a couple of times - mooching about - I'm only now getting round to fettling the TRX I bought from a friend-of-a-friend toward the end of last year.

The bike has YZF750 front and rear end with a 600 tail unit. At the moment it's fully stripped and the frame, swingarm, wheels etc have been powder coated. Although I've yet to paint the engine (next job) I am starting the rebuild (can't wait!) and cannot for the life of me find the torque settings for the four frame bolts that attach the engine bracket (as I believe it is called) that carries the swing arm. I was simply wondering if anyone can help as I'm buggered if I can find it in either the Haynes manual or the parts manual (that has a list of torque settings) and keep going through them in a state of total denial! Something of a hindrance to progress....

Grateful for any direction/ information anyone can provide.

Cheers, Johnners

Ey up. I just whipped mine up to within one grunt.

If you know the bolt diameter and thread pitch, a look online will fine you a generic torque figure that will be in the ball park.


Mark.

Thanks guys. Just realized I posted as a new member in the wrong section - doh!

Johnners,

See page 30 of TRX parts catalogue. Ref #2. Part # 4NX-21430-00. Rear arm bracket comp.
See page 2-13 of TRX service manual. Frame and Rear arm bracket. 55nm.
These two M10 bolts in frame.

Thanks Stu. Bang on the money. Clearly I can't see the wood for trees as I've checked your references and they are indeed there!

Thanks again.

No worries Johnners,
Happy to help.
Wack up some pics as you build, we like to see 'em going together

Will do. I'm taking the bodywork to my painter next week. He did a cracking job on my R1 doing an Yamaha Japan M1 race rep scheme. The TRX is going to be in Marlboro endurance colours. Hopefully I will get the engine painted and the rebuild completed before he gets the painting done (yeah right)!
