Babbit Thrust Washers
Are there babbit thrust washers in a ruxtel axle? I have never had one apart and if there are, are there are, were they used on both the right and left sides?

Re: Babbit Thrust Washers
Yes, theywere installed in a T Ruckstell when new but should be replaced any time rear end is rebuilt. And they were used on both sides
I don’t know why I turned out this way. My parents were decent people.

Re: Babbit Thrust Washers
Ruckstell only has one thrust washer on the right hand side.

Re: Babbit Thrust Washers
Free advice, take it for what you are paying for it.
Ruckstell rebuild.
Replace the ball bearing and the bronze plate. Those two pieces are critical to the alignment of the ring and pinion. Virtually every one of the bronze plates is dished inward -- some slightly and some a bunch and do not hold the ring gear/carrier/axles, etc., in the correct position.
The correct ball bearing s SKF #7212becby . Size is in MM as all bearings are: 60 x 22 x 110.
There are some on ebay right now for $75-80. Best bearings in the world, USA made, last forever.
Best investment you can make rebuilding a Ruckstell.
Then put a bronze washer on the other side instead of the babbitt after you get the new parts in and you are good to go.

Re: Babbit Thrust Washers
are they really babbit? i tried to melt on once, nope. i think they are pot metal. explains how they expand & crack with time.
asking the experts. am i too old, F.O.S. or both??
p.s. agree on the bearings. must be 7212, or it wont thrust for long. have seen 6212's being passed off. costly mistake.
i have straightened the brass bearing support successfully, but, there is usually too much wear inside. (P145 locking plate)
supports all the weight on that side.

Re: Babbit Thrust Washers
7212 is the size, Becby is the 40 degree angular thrust designation necessary for the Ruckstell application .

Re: Babbit Thrust Washers
If you support the bronze plate while pressing on the ball bearing, they won't get dished.

Re: Babbit Thrust Washers
to stan. maybe you got that backwards.
example: 6212-zz. the 6212 is a radial thrust bearing (same dimensions as 7212)death to rux. the 7212 # indicates side thrust. in our example , the the alphabet soup part. -zz stands for double shielded. that other letter combination refers to other features like bearing cage - bronze, sheetmetal, phenolic. seals or shielding etc. one need not limit oneself to your specific alphabetic suffex. however, sulfer based lubes can eat the bronze bearing carrier & rux bronze plate. (seen it, looks like termites)

Re: Babbit Thrust Washers
SKF does not manufacture a ZZ bearing. What you are referencing may be a 2Z.
6212-2Z
Deep groove ball bearings
d= 60mm
D= 110mm
B= 22mm
C= 55.3kN
C0= 36kN
It is not an angular thrust bearing according to the SKF site. It is a radial thrust bearing, not suitable for angular thrust applications as in a Ruckstell.
https://www.skf.com/group/search-result ... tem=metric
7212 BECBY is the same size but is an angular thrust 40 degree bearing, which is what the first B designates. The other letters are construction indicators as to the type of seals, ball separators, etc.

Re: Babbit Thrust Washers
I have a five gallon bucket half full of Ruckstell bearings I've pulled out during rebuilds. I routinely replace the bearing and the bronze plate with very few exceptions. I've done over 70 Ruckstells over the years but have too much other stuff going on to fool with them other than the ones I'm trying to get time to work on to go under my 27 coupe.
Bought these yesterday. They will go in mine and one for backup in the drawer where the last 50 or so went through. =)

Re: Babbit Thrust Washers
Thankyou Burt for posting the video and to all of you for the information.I learned a lot. I am sure the grease in mine is as thick as in the video, has not been run in 50 years. I want to get the motor running and then go to the Ruxtell. I think I will not have excessive expense there as I have quite a few spare Ruxtell parts. Thanks again.

Re: Babbit Thrust Washers
I bought a '13 a few years back, and needed to pull down the rear end to change the ring and pinion. The old babbit thrust washers were perfect!

Re: Babbit Thrust Washers
yea, did you reuse them? thats amazing. did you at least give them the drop test? I have not even seen a N.O.S. one i would buy or use.

Re: Babbit Thrust Washers
I've mined several rear axles for parts. In all but one the thrust washers were in pieces or completely gone. Here's the single survivor I've found.

Re: Babbit Thrust Washers
if you want to know if is was usable do the drop test. hold it up about 5 feet. drop it on edge.
it will probably shatter like glass. i have only had a few pass the test.(maybe 2%) still WOULD NOT USE them.
but its amusing to see how close to failure the rear end was.
that one you show looks like it will shatter.

Re: Babbit Thrust Washers
I have had (still have!) several original thrust washers as nice as the one Steve J shows! However, oh so many years ago, the very first model T rear end I rebuilt, I found the nicest one you could ever find. I had set up a work station at the back of my parent's place. When I was done putting the thing together, including the new bronze washers (I had gotten and followed good advice!), I was walking back to the garage to put some tools and things away. In one hand were a couple tools, and this absolutely perfect looking original thrust washer. It was clean, and shiny, smooth and beautiful with its flawless oil grooves and Ford scripts. And I stumbled stepping in a gopher hole. My hand tightened a bit, fingers only on some wrenches and that perfect thrust washer. And the thrust washer snapped into three pieces!
I have never seen a definitive report of what they were made of? Babbitt is defined as a wide range of soft metals used as bearing surfaces. They clearly are not Babbitt in the sense of main and rod bearings. But they are in the Babbitt spectrum. And they do resemble pot metal.
From that day I stepped in the gopher hole, I would never trust an original Babbitt thrust washer in a model T rear end. With age, they just cannot be trusted. No matter how nice they look.
