Re: Disc Brake swap for a 3/4 and 1 ton
I did a little more on the spindle spacer. Its made from 4130 Steel 2.25 diameter round bar.
The spacer dimensions are as follows
Seal journal diameter 2.110", The seal National 40973S ID is 2.093" OD 3.150" x .250" thick and leaves us with a .017 interference fit or seal lip stretch
Seal surface width 0.845" , this may be trimmed later
Spacer ID is 1.406" use 1.404 if you want a very snug fit, Measure your spindles first
Spacer bearing seat is 1.495" OD and 1.100" long
OAL 1.950 This may change.
