Doe anybody knows torque specs for clutch basket top plate five bolts? Model DT 175 G . Thanks in advance.

Not off the top of my head, but I think we might have a service manual in the Workshop Downloads which would have that specification listed.

Can't find service manual. Anybody have one?

Yamaha wrote one manual for the 1978 model and then added supplements for the later models. (The supplements show the differences from the 1978 model.)

The 1978 DT125E - DT175E manual can be found here using the menus at the top of the page. Go to workshop > service manuals.

The supplement I have does not list a different torque spec for the G model clutch spring bolts so you'd use the same spec as the E model which is 5 ft-lb... that's not very tight. (The screws are only 5mm diameter)

It's hard to find an accurate torque wrench that goes down to 5 ft-lb so I use an in-lb wrench. 5 ft-lb times 12 in-lb per ft-lb equals 60 in-lb.

I just looked it up in the Clymer manual (which we cannot post up for copyright rules) there is no specific torque listed for those. It simply says to tighten the bolts in a crisscross pattern in 2-3 stages.

The proper clymer manual to cover that bike is M412 which covers models from 77-83 if you are looking to purchase a clymer manual

Oh... one more thing... Yamaha has an annoying habit of listing some torque specs in the assembly text of the manual and other torque specs in the appendix. Sometimes the spec is listed in both places. Sometimes it is listed only in the text. And sometimes it is only listed in the Appendix.

The clutch spring torque spec is only listed in the appendix. Going by the manual page numbers it's page 154 of the manual you can download from this website. (Going by the pdf page numbers, page 159 of the scan)

Thank you all.

Just reassembled my DT175E.  Using a very accurate torque wrench I tightened the spring bolts to 60 in lbs but honestly think that's too tight.  As I approached 60 in lbs, it didn't "feel right". I'm thinking in this application, 50-55 inlbs would be good with blue Loctite for insurance.  The 60 felt like the threads were about to pull out or snap the head off of the screws.  

 

These days, I just snug them down.  No loctite  Never had one come loose. 

I have stripped/broken them previously by going too tight. 

5 ft-lb (60 in-lb) is the spec though...  but when I stripped one (with a torque wrench!) years ago I just started snugging them down. 

My father taught me, just go til your elbow pops once. Then they are tight!
