torque wrench

Torque wrenches are most accurate or calibrated about mid scale, a 0-150 foot lb wrench is not going to be suitable at 1 pound torque range. Something like a 0-15 with analog dial would be what you want.
 
Set the carrier (side) bearing pre-load first, while the pinion is not affecting the feel. Do as Tom says. New bearings should be set tighter than used bearings. I set carrier bearings with the axles in the vertical position, and use feeler gauges in place of gaskets to adjust things. Use feelers under the housings to adjust back-lash too, then on final assembly replace the gauges with appropriate thickness of gaskets. Do not tighten side-housing bolts without feelers or gaskets in place or the housings will bend and you'll have leaks. Use care, go slow, and have fun!
 
I realise the end of this thread is a year gone by ,,but can I ask when setting the pinion and side bearings preload do we do them dry and clean of any lube ,,,as when dry and clean there appears to be less drag ,,,thanks ,,
 
Just be sure that you do NOT try to use the "click" type to measure preload! Preload is measured while the shaft is rotating, thus the need for a beam or dial type wrench.
 
"I would never go back to a beam style, yuck."
You you can't set preload with a click type. Someone back in the string made it sound like you could give a good pull on the gear and it would spin one or more full revolution by it self! That would be way too loose. That would be like -20 inch pounds. :)
(Yes I see this is an old one brought back up)
 
Search for bicycle tool suppliers. They use torques in this range and they will be a flex beam. Be not afraid, no moving parts, whats to go wrong. Why spend $375.00 when $39 will do. After 10 minutes you will know the feel.
