When installing spindle bolts and bushings in a model T, to fit the spindle to the axel does one face off the top bushing, the bottom bushing or equally off both?? Thanks for your help.
It probably doesn't make much difference, but I only took enough off the top one to square it up, then took the rest off of the bottom one.
I figured the top one takes all the weight and could use all the thickness it can get.
Normally both are faced equal, the Service Bulletin, May 1927, states:
"when facing off the spindle body bushings, an equal amount of stock should be removed from both bushings..."
Repair methods vary if the axle yoke or spindle body faces have been worn and then filed or machined away more on one face than the other.
I face only the bottom as all the wear is on the top
I do like Mark for the same reason he posted. I do feel the clearance will last longer if the top is squared up. Imagine if it is only making partial contact on the top, it will wear quickly increasing the clearance. I take just enough off the top to square it, the cut the bottom to fit it.
Bob is correct, BUT, if you have new bushings, the bottom should still be faced off to be parallel to the top.
