Early Rear Hubs

[Ed Saniewski]

We were having our club garage clinic over the week end and when I went to pull a rear hub on an early 28 car I found no axle hub gasket. There was no recess in the hub for the seal to sit in. Was this something on the early cars? I put a little Permatex sealer on the washer and torqued the nut. Thanks.

Yep,...that's the way they were..

When did they start casting a recess in the hub for the seal?

The Castle Nut (a Special hardened 5/8-18 so it will take at least 100 lbs. torque without damaging the axel threads) does not use a hardened washer but torques directly to the end of the early 28 drum. If you install a washer there is not enough room when the drum is torqued to install the cotter key.

I thought it was in the Service Bulletins,..but I didn't find it. I would guess and say about
the change in the brake system..

Ron,...I have an NOS rear drum(which I'm sure carried the "AR" part number.
It has the late style hub, lug studs and has the counter bore for the gasket
at the axle nut..

What we found was we could install the steel washer and torque to 100 and install cotter but not if we used the steel washer and the seal.

I think we also noticed that the brake roller pins were smaller in diameter - we had to open up the hole in the brake shoe for new ones to fit.

Matt,

To my knowledge the brake shoe roller pin diameter has always been the same. Is it possible that the new ones you got my have not been made to the original diameter ?

Ron

[Tom Wesenberg]

I was thinking the same as Ron, and wondering if the new pins are oversized?

[mlp623]

Brattons pins, so I don't think so. Definitely would not fit though. I guess it is possible that the shoes were not correct? I will take pictures of the pins to compare.

[Ed Saniewski]

Matt, do you have a picture of the pin's I removed from the Shoes? The holes in the shoes may have been welded up the last time they were redone.I gust reamed them out ever so lightly to fit the new pin. The old pins had an unusual oversize head with what appears to be one flat side.

Ron, When I removed Matt's Hub, there was only a castle nut. I thought all cars had the washer under the nut. As Matt said, I was able to get the nut torqued to 100 ft./lb. with the washer and a cotter key.

Matt, Nick and I made it to Flint for the membership meet, but the forcast is for rain and snow most of the weekend.

Matt,

My A1276 had the flat side brake shoe pins.

The flat side pins were released Dec. 7, 1927 and only used thru Jan. 1928, when the pins, adjustment clevis, mounting bolts, brake shoe wedge, and dust cover were changed to the design used through end of production.

There were lots of changes to the braking system Ford made from start of production thru Jan. 1928; the Engineers were trying to solve a front wheel lock up problem; when they finally changed the adjusting wedge so it would only move up and down and not sideways was the problem solved.

Ron, the brake shoe wedge on Matt's car has a large washer holding the wedge in place and allowing it to slide up and down. Was this also part of the early brake system?

[Gary Karr]

My A3261 also came with the early brake pins with a flat side, making them look like a "D" shaped head.

[Tom Wesenberg]

Since the pin slides without turning, it seems like a flat side for a larger contact area would be a better design.

Do you fellas have a photo(s) of EXACTLY what your talking about,..please?

I do have some of the v-early brake parts..

[Ron in Quincy]

Attach are some photos.

[d.j. moordigian]

Thanks Ron...

[Ed Saniewski]

Ron, Matt's pins were a large D shape, the photo you posted shows an oval shape. I hope Matt can post some photos.

[mlp623]

Ah - That makes a lot of sense. We thought the D shape was an improperly installed pin. They are over at the garage, I will grab them tonight to take pictures. Should have them up in the AM.

Ed - Good luck at the membership meeting. Hope you sell that fordor.
