Default Rear Bearign Rebuild

Hi Guys,
Since this is always a favorite here and I'm rebuilding a set of arms now I'll post some pictures along the way.
These are off a 69 BB car and someone has been in there before. I found one strut rod was changed over to the larger head. The right arm was never apart- still had the factory seal and NDH bearings.
The left one had .030" endplay and a new cotter pin- bad sign. The threads were rolled and the inner bearing journal was crap after Bubba hammered the replacement Timken bearing on the journal.

Here is the spindle with the bad journal and threads



Here the race starting to go bad:




Here are the parts of the right spindle.





Gary

The races in the housing are removed by hammer and drift. There are spots to hit the race and drive it out.



Here what the front bushings look like- dry rotted and falling out:

Sure hope the rest of the car is in better condition! After seeing those bushing the owner may want someone to look at the front end as well.

Here is the press setup I use


Gary,

I am getting ready to press my rear bearings apart and have the same press setup as you have. I'm curious how you managed to get those two plates in between the spindle and the bearing housing to press the two apart. I'm having trouble making that setup. Thanks.

Mike, This car is being worked on by a local garage. I saw a lot of things that need to be fixed but the garage guy is calling the shots. I'm just rebuilding the rear end, T arms,and 1/2 shafts.


Rip, yes the endplay was pretty bad but it was a result of poor workmanship from a previous "mechanic" I doubt it was driven much in that condition. That's probably why I got the call- to fix someone else's mistake.

Steve, I strip the PB shoes out and always replace the backing plate so I can get the black plates under the plate and use a spindle knocker to protect the threads and press apart. This job the right came apart without much force build up and the left was so screwed up it came out as I was tapping off the spindle support.

Thanks Gary, that makes sense.

Worked on the arms today. removed the bushings, stripped, washed, and painted with Eastwoods rust encapsulator. This is the 1st time using the eastwood product,usually I use POR15.

Gary, I've always been curious about something. Do you ever find the spindle journals to be slightly egged? Mine were close to half a thou egged to the plus side.....at least according to my bearing charts. The finishes were still near perfect......just egged....which is not terribly uncommon on a shaft ground between centers. Half a thou doesn't sound like much, but it essentially doubles the amount of interference on two sides of the journal.

Hey Gary,

What do you get for a TA rebuild (assuming spindles are OK)? I may be interested in running mine down to you this spring. PM me if you want.

Thanks,

I do remember you telling me that last year. I know you know your machining trade very well, so I would doubt it. I haven't go beyond checking for damge to the journal or surface but will check and see. I have the used spindles here and a new one on the way. It will interesting to compare the two.

If you want to get the races out without a chance of damaging the housing use a tig welder and lay a bead on the race, it'll practically fall out. If you don't have tig but a mig it'll work too as long as you leave the housing a bit greasy to avoild splatter from sticking (or use anti splatter spray)

The races in the spindle housing should come out without much effort since they were sealed against the elements.

The Eastwood paint doesn't self level as good as the POR15. It sets up much faster and has a satin/flat sheen. I may or may not top coat it.

Steve I PM'd you some info this AM.

Installed the front bushings this AM. I touch the sides quick on a belt sander to remove any hgh spots.

Gary











Here are the Right side parts cleaned and ready to set the end play and assemble.
