Starting Crank Bearing

Post by Dan 82-A »

Is the Starting Crank Bearing for a 29 AA the same as a 29 A? This would be part number A-5461-B.

I see there is an AA-5461 listed for 30-31 in the Parts Price List, Effective July 1, 1931, but I don't see a listing for a 28-29 Starting Crank Bearing.

The reason for the question is that there is a Starting Crank Bearing in place on a 29AA which looks a larger/taller A version. This is one with the U bolts. The problem is that the hand crank won't fit into the crankshaft nut, the bearing makes it too high. The motor mounts are all stock and in good shape.

The 1929 AA used A-chassis, A-5461 starting crank bearing. This bearing has flat flanges for the square-design spring clips. Starting June 1929 an oil hole was added to this bearing (this was the design 3 bearing). A bearing which requires u-shaped clips is incorrect.

The A Starting Crank Bearing will be easy to find.
I'll have to start looking for a couple of AA-5455 spring clips to fit what ever spring is under there, I may have one.
Thanks Neil!

More than likely, your 1929 AA has the front cross member with a slightly wider channel (1/29 Ford Service Bulletin). Consequently, it requires the AA-5455-B clips to be used with the AA-5458 design 2 clip bar (see attached). I don't yet have a drawing the the AA-5455-B clip (but, it will be slightly wider than the AA-5455 clip). This drawing will be orders in the near future.

Ok, I will check out the measurement of the clip bar when I get it off.
The crossmember does have a reinforcement riveted on the underside area that meets the spring.

Your #1 cross member is most likely a replacement. Ford upgraded the service cross members to include the reinforcement (like the 30/31 cross member).

Thanks Neil.
Yes, I took a closer look and the crossmember is bolted in.
