VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 Rear axle seals for 1927 LM (1 ton truck)

The rear axles seals are shot in Lurch, my 1927 cattle truck. The brakes are covered with a yucky oil/dirt/who-knows-what slime. The linings also paper thin, so they need to be replaced (winter project).

I've read postings on this site that suggest putting in new seals with neoprene, and separately, suggest replacing the bearings with sealed, new ones with one seal removed.

I think my bearings are okay, but I suspect the newer seals that are for sale are for the cars and 1/2 ton trucks will not fit the 1 ton trucks.

Your thoughts and opinions are appreciated.

Thanks! Dean

You need to purchase a reprint of the 1928 4-cylinder parts book. That, and many more questions, can be answered by that book. Also consider an Owners Manual and a Repair Manual. All in reprint.

Dean,

I think I have a set or two (NOS) rear seals for my '28. Let me know if you need seal numbers from a clean seal.

I would definatly go with modern seals. They are going to seal a lot better than the NOS felt or cork ones. I usually just visit my local bearing store with the old one in hand and they can usually find an equivalent that will fit. They are usually pretty reasonable in price as well. Sometimes you can take the old seal apart and just replace the felt part with the new seal.

Thanks guys. When I tear it down, I'll post what I come up with.

Cheers, Dean

Hi Guys,

I fully support Arends comments, go modern, on the inner axle seals also. Billy Possum makes neoprene versions. So much better than the original cork or leather or felt versions.

Howdy,

I finally got around to working on the '27 (been busy with the '28). I decided to replace just the outer bearing seal. I figure that if grease 'leaks' towards the differential, that's okay. Likewise, if a little heavy oil 'leaks' into the bearing, that's okay too.

I just don't want either oil or grease leaking onto the brakes.

Turns out that a SKF 16406 neoprene oil seal is a direct replacement for the felt outer seal on the '27 1 ton truck. The local King Bearing had them for $12 each. ;-)

B & A Friction company in San Jose is relining the brake bands for me. As per suggestions in other posts, they are putting 1/4 inch soft woven brake material on the bands. The cars and smaller trucks use the 3/16 inch, but old material on the bands suggest that the 1 ton needs 1/4 inch material (in spots, the old material has a thickness of .210 inch).

Cheers, Dean
