AS some people know I've been going thru the parts bin looking for XR parts. I have several hydraulic brake rearends in stages of assembly. One I took and removed the center section in order to straighten the axle tube. I talked to "GEORGE" the owner of ' THROTTLE MASTERS" about this and in the interim we never discussed reassembly. How does one index the center section housing to coorelate with the axle tube? ( In other words,how do you press the splines back together to ensure the three rivet holes line-up?,or make sure the chain doesn't chainsaw it's own clerance?) ALTHOUGH I have my own ideas on this subject, it would be interesting to hear some different opinions.
