Same goes for this one, you find something amiss here let me know and I'll change it!

Martynn,
The spool at the rear does not show a couple of details. The front flange is narrower than the tops of the ridges through which the bolts pass, as though it has been machined down a bit. This is to allow it to nestle into a corresponding relief in the rear end of the torque tube, which has a raised edge around it. At the rear of the spoolthere are cast in 'ears' protruding outwards around each bolt. this feature distinguishes them from the earlier ones which do not have the 'ears'.

Allan from down under.

Allen do you have a picture of one of these things? I think I know what you're talking about...it's like a relief cut on the flange, right?

Like this?

The tubular bits through which the bolts pass are taller, making the front relief look more pronounced, and adding a raised section at each bolt hole on the rear of the housing. I have a phone camera, numerous housings but no idea how to post photos on this new phone, so a thousand words will have to do, unless someone else can post a photo. As I said, it is this raised section which distinguishes the later housings from the early ones.

Sorry Martynn.

Part # 2578E. There is one on top and bottom. Access the U joint pin.

Ok, was wondering about that....also made some changes to the bearing, seems the one I've got shown is a later style for 22-27.

At this time it is supposed to be independent balls and cup that holds them and an outer race (that looks for the world like a hardened washer), an internal retaining ring and the distance plate that takes the thrust stress off that retaining ring by fitting inside it against the outer bearing race.
