I dug into another rear axle today to see what I could find.
Some nuts take a bit of extra leverage...
...and some bearings need a little persuasion to come out.
This one was early enough to have the enclosed spool held on mostly by studs (one bolt).
The differential carrier was held by studs, not bolts.
This was the first one where I've found both babbitt thrust washers intact.
Original Ford equipment.
Also genuine Ford. (Avoid those spurious parts.)
That's pretty cool, Steve. I had no idea babbitt was so porous.
I didn't realize that Ford made a 12 tooth pinion. I thought they were all aftermarket. How many teeth are on the matching ring?
No keyway so not pinion, spider gear.
Thanks Kerry. I knew it didn't make sense.
Maybe it didn't make sense but here is a for real Ford script 12 tooth pinion. Early sedan gears 12-48 that were offered before Henry started cutting the infamous 10 tooth. The other larger 12 tooth is an aftermarket 12-39.
I believe that BR stamped on the script gear is the beginning of a telephone number.
Note that on the aftermarket gear the keyway location is off 1/2-tooth, putting the corners in line with the valleys between the teeth. Those have been known to break there.
Daniel, the babbitt in the rear axles isn't the same as the babbitt used in the engine. The color suggests lead content. No lead in the engine. The lead may contribute to the tendency for old thrust washers to break, might be some kind of internal corrosion just like in old pot metal parts.
Mike, i think you are right "BR 549"
Thank goodness! I was beginning to wonder whether you guys were paying attention.
Especially after "no comments" on my mention of "Bye-bye, Miss American Pie" on Feb 3rd.
Ah...thanks for the clarification, Roger.
Mike sometimes when I think of a good one people who know me just roll their eyes and make no comment.
You did have two follow ups that day.
Is there a emoticon for that situation?
