oil seals and prop shaft UJ

Valcuda · Post by **Valcuda** » Fri Jul 20, 12 10:30 am

After years of an oily garage floor below the Cape Town Cuda, I've decided to take action!

The pinion oil seal on the rear axle (7 1/4") needs replacing, as does the slightly worn prop shaft UJ. I assume these are standard American components and are thus obtainable from the usual suppliers, like American Autoparts, W-A-S-P, etc. Am I correct?

The guy who's going to press in the UJ for me said he could do the steering box oil seal while the car is up on the ramps---when I mentioned the almost irremovable Pitman arm, he wasn't fazed and said he had a hydraulic puller which would get it off. In that case I may as well go for it. However, as you'll see from the attached picture (of my spare box from a scrapped South African car), it's not an American steering box but an Australian Chrysler Valiant box--you Valiant guys will know the type. Where's the best place to get a replacement seal for this?

once you have the old seal out head to Orbic Bearing in croydon and he should have the seal or can get them.
I got mine from them.

its just a mopar saginaw box like a US box

but

the case is cast iron and different shape

and the ballnut fits onto the screw inside, upside down to make it compatible with a sector shaft that meshes with the ballnut tapered teeth on the left hand side away from the chssis rail in a RHD car rather on the right hand side away from the chasis rail in a US LHD car

other than that its a mopar box that shares a multitude of components with US mopars (not pickups)(passenger cars only)
and

many chevys and fords

so if anton has found a seal for a US box in croydon
and that US box has the same thickness sector shaft

you are onto a good thing, the same seal will fit
if not its a case as he states of going and finding one

otherwise it is

australia
or
US

suppliers

and the cost of a seal kit for a manual box varies hugely

jims autoparts in the US always has them when jim isn't spending the millions he makes by charging double what everyone else does for the most insignificant parts

try local or Rockauto

firm-feel in the US can probably help as well

or punt an email to Ray at pentastar parts and restorations in Australia...

or just fill the box with grease...mines been like that for 10 years now

I would take the punt and get one in advance considering you should be able to get it at a reasonable price.

Part number 2127154 from the Aussie parts book, images below.

Ebay search indicates this is a valid US part number too.

As Dave said likely to be the same as the US LHD, have a look at the dimensions in the pic below from Rockauto for a '69 Dart.
Very similar to the Aussie power steering one by the dimensions! So this may not be US manual steering... I can not seem to tell.
Would be good if you can find the dimensions for the part number 2127154 somewhere.

Note the Timken part number 8659S and dimensions and see what you can find from a local bearing shop maybe even an on line bearing shop.

Nothing to do with this question but just wanted to say, where else on the net does anyone get such knowledgeable, quick, friendly advice as this.... Awesome gents!

PS

note that the diagram VIP has put up is indeed from the aussie manual

BUT
its actually a US box with the K member mount rather than the chassis mount like on the aussie RHD one

That is true, CAL seemed to use quite a lot of the US diagrams throughout the service and parts manuals where the RHD was actually different.
But all the part numbers should be correct.

Has anybody got a pitman shaft in front of them or can remember, does it get larger beyond the splines as you go into the steering box?

On my spare box at the end of the splines is a peripheral groove and thereafter the shaft vanishes into the seal. But the diameter of the shaft between the splines and the groove is 1.125", measured on callipers. This differs from the shaft diameter of 1.247" mentioned on the Timken specification that VGVIP posted.

I've emailed Pentastar to see if they can give me some seal measurements.

I suppose I could get the old seal out of my spare box and take that to Orbic Bearings as Anton suggests. (At the same time, I'd see if the pitman shaft increases in diameter!) But if any of you guys already know......

Seems like the seal I posted before from rockauto is for powersteering then.
Just found this when searching on the part number I posted from the Aussie parts book....

power steering sector is either fatter or thinner

i know the pitman arms don't swap over

If its leaking trot along to your local Landrover place and buy some "one shot" steering grease it goes in the steering ball on the front axle, its runny grease but not to runny for your box , had some in mine for years and it dont leak !
