what kind of torque wrench?

[rustybronco]

1/2" craftsman micrometer 20-150 ft-lb click style (74-ish), 3/8" craftsman microtork 25-250 in-lb click (newer), 3/8" snap-on beam in-lb (70's) great for checking pinion gear rotating torque.

I've been using a 800 in/lbs Proto clicker for years. I'm happy with it. It would be nice to have a bigger ft/lbs wrench for the rotor nut and counter shaft sprocket.

Tell that to the guy whom last week was asking about his snapping off of oil sump bolts and the few stripped drain plugs mentioned in the last week.

i would have told that guy that on those bolts i go only "snug" by hand, then check for leaks after riding the bike and tighten a bit more if needed

I was that guy. The service manual had the wrong torque spec and the other manuals copied it (like they copy everything else).

yeah, i remember your thread, cant remember if i said anything but the torque spec you mentioned seemed too high for 6mm bolts in alu threads

I downloaded the service manual for the '83-'86 GS700/750 and it specced 7 ft lbs for the oil pan like all the other 6 mm bolts, so I put it together.

A guy on another forum seized his brand-new top end because the manual had the bore specs swapped for the smaller and larger bore version of the same engine.

yeah, when put in a perspective you're the lucky guy!

but i would have thought that a good machine shop would ask for a piston and rings when doing a re-bore and not go by the numbers only

The bolts snapped just below the head and I had a parts engine. No big deal, just annoying.

The numbers on the bore were only off by a thousandth of an inch. The machine shop here mainly works on tractors and huge V8s--they do motorcycle cylinders but very rarely so I think they'd be lost without the numbers. Actually the machinist couldn't remember the last time he had worked on something so small.

PS,
When your thread was going and you were working at 10# or so on a 6mm bolt, I said that is stupid. 6mm bolt go to 5-7 at the max, so I pulled out a few manuals and they were calling for 7 - 11#. Some times doing it by the book doesn't work if the book is wrong.
I did not post anything since it appears the error in the manuals is now known by a few at least.
