The 8-5-28 parts book lists the brake rod clevis and the low pedal clevis as the same part. As is often the case, it doesn't differentiate between the early version and the late version, but I don't think any of mine are either. My non-Ford (or Model A?) ones work just fine, but I want to watch for some correct ones at swap meets. Anybody have some good pictures of the 1909-1919 clevis and the 1920-1927 one?
Non-Ford? Model A?
I might have a few of the short T-3447 clevis, I will look, Bob
When they were two factory numbers...T802/FN3447 was 1-3/4" long...and actually used from 09-27 according to Bruce listings...
There was a T802/FN3467, the one for the brake, and that one was 2-1/16" long. But that only made it to the 1915's...then apparently T802/FN3447 became used in both places. There was also a T47/FN3467 Brake Clevis that was used from '09-'11, and that one was 1-3/16" long.
Sorry for the mixed number nomenclature, I always quote both part and factory number to folks when referencing part...some stay in the part number domain...others stay in the factory number domain...some just get confused...and the reason I always use both is again evident in this question...see a part number change for the same factory number on the brake clevis?
I also don't have the drawings for something like this so someone else will need to show a pic or identify for Steve what is what. I'm not sure where the dimensions mentioned apply to either. In the era it was common for clevis 'size' to be from the centerline of the hole to the edge for some folks...overall length for others.
These are examples of the early low clevis.
The T-3447 Slow speed clevis, Factory # 802, is listed in all the parts books from 1920 and up as substitute for the T-3467 Hub brake lever clevis.
For the earlier brake rods, the clevis is a forged part, with Fac# 802 on the clevis. Use this for slow speed or brake rod. Correct for the forged end brake rods.
Then the T-3447 was changed to a rolled part, with split, and was used on the later up to the end of production.
Excellent! Now I'll know what to watch for.
You will notice the clevis pin that Royce posted. That is the type used on the early T's, but I'm not real sure when they changed to the later style. The clevis's that Steve posted are very common, but were not used on T's.
Lang's catalogue says 1920. Rodda doesn't cover them. I haven't done any other digging to find out if 1920 is correct.
Rodda's picture book says the split type brake rods were 1919. MTFCI Judging Standards. says Aug 1920 the split brake rods were first used.
Those forged clevis were used with the forged brake rods, so that would be those forged parts were used up to Aug 1920. After that, the simple split end brake rods, and the split type rolled clevis were used.
Good example of Ford's engineering ways to find a good design at lower cost, that is what made the Ford so successful. Better and cheaper!
Yep, I saw the rods in the book, but it didn't occur to me that the clevises would match them. That makes sense.
The earliest brake rods had an angle bent end at the rear wheel hub. That angle bend was NOT in the brake rod but was in the end clevis part. Used at least through early 1911.
