balinwire created the topic: Caution on reassembly
The Cord front bearing and Rezeppa joint housings are different between the 810 and 812. The 810 had Lockheed brake backing on most models. Another difference is apparent and that is the bell housing seal.

On the 810 it had a large right hand thread brass castle nut that was effective. On the 812 they changed from the large castle retaining nut to a four ? in. flathead screw seal plate. I can only imagine that this was changed because most mechanics did not have the proper spanner for removing the large brass-retaining nut.

On opening the housing and setting the grease filled Rezeppa joint axle on a pad in a safe place on the garage floor. I then did an inventory of all the loose parts and found that one 1/4in. screw was missing. Well if something had to get lost that was a good thing to loose as they are hardware items.

The grandson was to blame as usual. Missing toys, missing screws of course. I proceeded to collect the parts and reassemble new bearings seals, etc. I got to the Axle coated with 1 lb of grease and was going to put it back with the old grease but said I would clean all the grease off it just for good luck as it seemed clean and free of dirt and sand. Well what do you know, there was the missing screw in the blobs of grease! If it had stayed it would have tore the joint all up when it was spinning. The screw is steel not brass.

So the extra time cleaning was well spent and check those joints before reassembly! Any ideas why Cord redesigned this part <!-- s:?: --><img src="{SMILIES_PATH}/icon_question.gif" alt=":?:" title="Question" /><!-- s:?: -->

My theory is that they ran afoul of the original vendor $$$ wise and had to locate another. My 2nd theory, which holds water, is that the later design was cheaper! Either worked well enough. Just think, all they had was leather to make seals out of. In our shop we use modern lubricants designed for FWD and never use more than 12-14oz. The new stuff doesn't channel, seeks heat, and doesn't make any pressure. Originally Cord used liquid lubricant in the joints and couldn't keep it in!
