Torque Tube Bushing
Hello, I believe that I have the torque tube outer race bushing properly installed, but would like confirmation. The tit at the top must be engaged in the relief hole bored in the tube, as the outer edge of the bushing in flush with the bore. Also, the new replacement cartridge bearing is taller than what was removed. The old bearing with the thrust washer is exactly the same height as the new bearing without the thrust washer. Is the thrust washer to be discarded when using the new replacement bearing?

Re: Torque Tube Bushing
If you don't have the sleeve protrusion firmly seated in the dimple, once you have the torque tube installed you will not be able to get the roller bearing in. I make sure the dimple is perfectly clean before installing the sleeve. Take a punch and tap the sleeve in the dimple a couple times. Look to see there is no gap in the circumference of the sleeve.
Hopefully you installed the new grease seal in the torque tube before you installed the sleeve. Tom Endy |

Re: Torque Tube Bushing
OD of bushing follows circumference of bore. The reason I was questioning its installation is because the top edge of the bushing partially covers the hole machined for the speedometer drive gear housing. The housing does bolt up however with the driven gear installed.
What of the difference in height of the new and old bearings? |

Re: Torque Tube Bushing
Anybody run across this variation in bearing height??? Looks like the thrust washer it to be omitted, no such instruction given with new part....

Re: Torque Tube Bushing
Are these the bearings not to be used for the same reasons as in the transmission.

Re: Torque Tube Bushing
I agree with RedmodelT that the sleeve does not look fully seated in the torque tube. Have done many of these and have never seen part of sleeve protruding into drive gear opening

Re: Torque Tube Bushing
What's wrong with the original bearing ? It looks like the sleeve is not seated .

Re: Torque Tube Bushing
The original roller bearings with the spirals seemed to have survived very well as long as they were properly lubed. Apparently, there is not much pressure on them when in service.
About 90% of the differential overhauls I do, I find the original seal and race Henry installed when the car was new. The seals are always shot, but the bearing race is usually in good shape. Definitely stay away from the repos. Attached is how I go about replacing both. http://www.santaanitaas.org/wp-conte...-race-seal.pdf Tom Endy |

I have been known to "buy the bag of Model A parts" for small money on Ebay simply because there are a couple of the Hyatt-type spiral roller bearings in the bag. Joe K
