Re: Pinion diff bearing #18

Chris- My reverse scroll on the original cap had no damage, so I simply put it back in service. It does not leak. My pic above shows what the undamaged "seal" looks like. Checking and replacement of the carrier bearings is routine maintenance on a gearset like this. It can be done with the diff in t...

Re: Pinion diff bearing #18

Chris, you will find that the #18 original bearing can be replaced with a 5305. 62 x 25 x 25.4 (1"). I used a SFK5305A along with the original undamaged scroll seal cap (#20). The bearing is/was a double row angular contact bearing. The other (roller) pinion bearing #15 can be replaced with the SKF ...

Doug is a great source of parts, and his "tech tips" are full of useful info. He will not mind if I take issue with how he has assembled the cap.

Re: front wheel bearings.

Sounds like the hub "races" are ovaled out as described above, and the bearings got glued in off center.

Re: front wheel bearings.

Thanks for the end float correction, Steve. I used the Jim Buell article http://www.mg-tabc.org/library/Buell-TC-Frontend-3rd-ed.pdf as a guide when I converted my new hubs. Last page. It calls for 0.002" - 0.005" end float with tapered bearings. Easiest if checked on a dry (no grease yet) assembly....

Re: front wheel bearings.

Probably bad adjustment or not exact spindle/bearing spacer length lends to the ovaling out of the hubs. Needless to say, bearings that are not perfectly centered (or moving around slightly) in the hub are going to make it quite impossible to ever set up the steering in a satisfactory way, whether u...

Re: front wheel bearings.

Most people with any mechanical knowledge know what a race is, but few can imagine a front hub without any race. British refer to races as cups. Steve, I was talking about races in hubs, not in bearings. Any of us that have converted our hubs to use tapered roller bearings-- have races in our hubs. ...

Re: front wheel bearings.

The TC front hubs are different from "modern" hubs. They have no (ultra hard steel) bearing races that are pressed into the hubs. Instead, the hub acts as the race, and the bearing is simply pressed into the hub. What seems to happen to TC front hubs is the hole where the bearing goes into gets oval...

The ability of typical (DOT 3/4/5.1) brake fluid to evenly absorb moisture is actually a desireable characteristic, as long as the fluid is flushed every few years.

Re: Parts needed for internal TC Differential

Where is that diagram from? Does not look like TC. For instance, where are the oil seals? Bearing #15 shows an unnumbered bearing race next to it that does not exist. Moss catalog diagram is more accurate to original.

Re: Wheel bearings

Norman, I think you replaced your pinion bearings (double row angular contact ball bearing, and a roller bearing) around the same time I did. Hopefully you got some good bearings in there. Or did you go with the tapered conversion? So far I only have used tapered bearings on the front axle.

Re: Wheel bearings

Norman- Not sure if you are using old front hubs. TC front hubs had a way of ovaling out the opening where the bearings fits in. I had to buy new F hubs, as the originals were ovaled out. Original ones did not have bearing races as we now have, rather the hubs were simply machined to accept a presse...

If you want to run the copper wires you will need to upgrade to a more robust ignition unit with an external "box" like Crane, or run points/condenser. Pertronix/Powerspark type magnet units are inexpensive and usually work fine as long as you follow all the fine-print instructions. Things like pola...

Are you using standard T-type spark plug wires? The Pertronix/Powerspark type unit is not made to work with copper wire.
