Hi all,
Right pissed off...
I got a yamaha XT600 i have been putting back together. I wanted to do things properly, so i bought a couple of expensive torque wrenches. Trouble is, the torque settings given by the maker are simply a load of rubbish...
Take the M6 exhaust stud bolts into the head, Yamahe seem to think you should do them up to 8Ft/lbs Absolutely no chance, they would just snap off.
It seems to me that they have just reproduced a table of standards tightening torques for HT bolts in the various bolt sizes and think that is ok... Take the exhaust clamp halfway along the exhaust, you know, a bit of a pressed steel thing. Yamaha seem to think you should do this up to 18 ft/lbs !!!!! this would just demolish the clamp..
This afternoon i was fitting a new rear sprocket [10 x 1.25mm nuts] According to yamaha, you need to do these to 43 ft/lbs. Well, there I was doing this. It seemed madness to me, but i thought, "well, that is what the makers say" when i was doing it i thought, "never in this world" but i perservered and what happens?? Strips the thread.... Not happy..
What you all think??
I think forget the torque wrench and just use some judgement.
Tell you one thing though, NEVER buy a yamaha... Mistakes in their parts books with drawing with glaring errors showing items in the wrong place, part numbers transposed, cannot even write their parts books properly.
john..
