What is the difference between 2509 and 2509 B bearing sleeves? Is there a difference between the inner bearing sleeves as well?

From what I remember the 2509 is the right side and the 2509B is the left side. The inner and the outer sleeves are the same on each side, but the right and left are not the same.

You're close, Henry. :-)

Left inner and right outer are the same, and right inner and left outer are the same.

It sound as if you guys are comparing belly buttons
Innies and outies

Mike,
According to Mac's catalog the two on the left (both inner and outer) are the same and the two on the right (both inner and outer) are the same. It even says, "Hold the T2509 or T2509B sleeve so that you are looking at the "V" slot with the slot pointing down. If the hole is at the right, it is a right sleeve. If the hole is at the left, it is a left sleeve." There is no inner/outer distinction.

Doesn't it make sense that since the axle rotation is the same on a given side for both inner and outer bearings that the sleeves would be the same?

Also, I just noticed that there is an exploded view of the left side axle assembly. It clearly shows both the inner and outer bearing sleeves. Both are T2509B.

Actually the illustration uses T2509BTQ, meaning it's their "top quality" sleeve. But that has no bearing on the question of B designating a left side sleeve for both inner and outer bearings.

FWIW, my 1917 Ford parts book lists 2509 for the right and 2509B for the left.
