Focus on the ability to roll
The axel spacer limits the guess work and ability of over tightening bearing races effectively eliminating the possibility for one to remove built in clearances, improperly loading the wheel bearings. The spacer, a piece of chrome molly. tubing turned down in the center of two outer flanges removing extra weight. Two rubber O rings installed on the undercut area of the axel shaft support the spacer on center. The modified bearing races join up to the sleeve carrying the new ball bearing allowing the bearing to float a predetermined amount. I have allowed .010 axel end play. After final assembly and sufficient tourque applied I will re-measure the end play of the hub assembly and make adjustments I determine necessary.
On to the clutch, the original steel plate did not fit freely on the releasing disc. This would explain why the steels had some color in them. I determined the O.D. of the releasing disc to be at fault. Inserted into the Parker Majestic O.D. grinder and indicated to run true as possible about .005” I was able to remove a small amount of stock and allow the mating parts to fit without interference.
The Freewheel clutch outer plate is new old stock and for good reason, it also did not fit properly. Binding is the devil when it comes to assemblies. The three drive pins interfered with the holes in the releasing disc. Into the Monarch lathe to take a slight cut on the inner side of the pins. This did not work as well as anticipated so a little work with a hand grinder and a hand stone to finish polishing the faulty surface. A test fit found all the clutch parts cohabiting just fine.
Finally for the night was to introduce the throw out bearing components. The three holes in the Freewheel plate were tight to the mating triangular disc pins. Drilling the holes slightly oversize allowed for ample clearance and once again all parts are fit and ready for plating.
I thought it to be prudent introducing the gauging equipment, after all these instruments are the true unsung heroes of these machining and fitting operations.
