What should hyatt bearings measure for TT to be in spec? Thickness of race also?
Are those the bearings in the muffler or the radiator ?
Fender bearing withe the rolled edge
.562" for the TT axle Hyatt's. Up to .005" under is acceptable if not pitted.
Book only talks about physical signs of wear (a significant shoulder or lip near the top outer edge and should be replaced) for the sleeves is what I found.
Others may have differing experiences, but when I took my TT axle apart I found everything OK on the left and a badly worn axle bearing surface and bearing on the right. Even with the severe excess wear to the bearing and axle, the sleeve was OK.
I disassembled my TT rear end because of a lot of play at the right hub. The play was primarily caused by wear on the axle bearing surface, not the bearing nor the sleeve (the bearing had OK diameter at the center of the rollers but they were badly rounded at the ends). Since you obviously have concerns about the condition of yours, I strongly suggest you include checking the axle itself for proper size at the bearing surface.
If the Hyatt bearing is ungular in detent, will the Mutri bearing and
side vent shim pocket need disassembly and inspection ?
Burger, Dallas, you both should know darn well that Burger's method is AFTER the ball-unit introduction.
The Mutri bearing is just a clever disguise for the plain bearing (bushing style) if you would've read the history.
How are those Hyatt's and sleeves, Dallas?
Duey, they cleaned up well. Nice coat of gear lube should keep the rust away till I need them.
Plain bearings? You can only get those in Kansas. They have a large flat spot on them!
If the ball units use the Timken type overage dampeners, are those the
type that were introduced in late 1919 with the special finned cover ?
