I am at a loss to identify what appears to be a retainer ring for the differential carrier bearing in a 1966 Type 3 swing axle. The part in the attached images is the ring with the 3 holes. I wish to remove the axle but do no know how to remove the ring to access the circlip. Any ideas greatly appreciated!

I´ve never seen that before, and i looked at the parts diagram thats on here in the technical section and did not find anything there either.

But looking at it; it looks threaded and the two holes opposite each other i think they are for a tool, similar to the threaded nut on an angle grinder. Try to check closer and see which way the thread goes, put a center punch or something like that fits well into one of the holes and see if you cant get it to move some. Could be that the threaded ring is to set bearing pre-load?

But as soon as the US wakes up, i´m sure that you will get additional suggestions, and probably someone that knows exactly what it is and how to get it off! Smile

I have the same Diff, this has the threaded sides instead of clips. I did not install mine so I don't know of a special tool, but it is threaded for sure. Mine was installed with thread locker also so I can't image how hard that will be to remove.

You may be able to use a Bicycle Pin Spanner wrench from Park Tools, or you may have to make something.

Good Luck.

Aftermarket superdiff, remove large bearing, remove roll pin in diff housing, then unscrew threaded ring. There is no circlip.

Thanks for your help, I have the diff out of the vehicle and wish to swap long axles for short. Do I have to remove the large bearing to release the axles or can I simply unscrew the threaded ring?

I have assembled new ones of these myself. There must be something holding the ring to keep it from un-screwing, it does not screw down tight because it sets the diff gear set backlash, if you do that it would not turn and you would have a locked Diff/spool. Figure out how the builder locked it, most with the big bearing off drill threw the diff and into the ring and install a roll pin to keep the ring from spinning.

Correction, do you see a allen npt set screw in that split part of the ring? Remove it and that should allow you to un-screw the ring.

Hi Dan, You have been a great help. The problem was a small pin under the carrier bearing. I was unable to remove the bearing so had to hand over to a specialist. Anyhow job done, sorry I do not have any spares - the only parts over are two long axles, located in regional Australia. Rolling Eyes Rolling Eyes
