O.K., I got the pattern set on the ring and pinion. My backlash is .009, now to dissasemble add the crush sleeve and set the pinion pre-load. Problem is that I can't find a beam style inch lbs torque wrench to beg, borrow or steal. None of the rental places even have them, is there a trick or something to get around this? I really don't want to buy one through the mail order to do this one job. TIA

When all else fails, you could probably make one and come pretty close. Think of this, 12 inch/lbs is a force of one pound applied one foot (or 12 inches) from the center of the pinion. I used a spring scale (that I checked by hanging a one pound weight off of) and a dowel affixed to a socket that fits the pinion nut that was one foot long. I oriented the housing so the pinion was hanging. That way you are not trying to overcome the effects of gravity. This is what I did and believe I got very close. HTH

Sounds reasonable to me. You should try to get between 19 and 22 inch pounds, if possible.

in a recent article in CHP (I think the one BGH was in on), they used a bar bolted to the pinion with a hole drilled 12" from the pinion centerline. They then hooked a fish scale through the hole and used it to measure.

You would probably want to check the fish scale first to make sure it was OK.

O.K, I cut a stick to 12 inches from centerline and hung 1 3/4 lbs of sockets from it. Tightened the yoke till it just barely spun, then checked the resistence by finger. It seemed to be really smooth, guess we'll find out. Thanks for all the help guys.
