I took the outboard bearings out of the Dedion tube last weekend and found they were held in place with screw in rings - different from the normal retainers. I had to destroy them to get them out. The factory tool will not fit these retainers. OK, i decided I'd order some new retainer from Centerline.

What do they send - the wrong retainers. The picture on their website show the correct retainers but they don't have them.

Here is a couple of pictures we took. If you know anyone who has the correct retainer rings, I'd appreciate a PM.

GTV6 use the type as shown at top. Milano used the lower type. I think the Milano style can be used, just need a different tool. Bearings are the same for the Alfetta, GTV6 and Milano. Have a machine shop make a tool to fit the new retainer. That is what I did.

They are interchangeable. It is not a wrong bearing retaining ring. There is an Alfa tool for that type as well. Be aware that left and right are different. One side is reverse threaded and the other is regular threaded.

This guy makes the tool you need. Almost certainly cheaper than a machine shop could do it.

Whil the Milano retainers fit, and work, I would consider them the wrong type, and undesirable.

To remove them, the tool exerts some 'outward' pressure on the retainer, pushing the retainer against the threads. This can make removal more difficult.

The Alfetta/GTV6 style retainers work in such a way that the tool torques them without pushing the threads outwards.

I always try to use the Alfetta/GTV6 style retainer rings. And don't forget the Never Sieze!

I have both of the tools from these guys, still need to do them on my GTV6, I also might have a home made one from a 4wd axle nut which may be what you need. Let me know if you want to borrow them.

There are in fact two types of retainers. Sourcing either of them has become incredibly difficult. From our suppliers, it is often quite random which type shows up. Sorry if this causes any issues.

Joe:

It's not a serious issue, but I do like to have it "Right". It's one of the many things becoming hard to find. I really want to get the correct rings because of what Brian S. said; and also - I only need one tool for both of my Dedions. The Milano rings seem to have to be trashed to be removed. The factory pullers tear the bearing in half when used to extract it from the housing. I have removed these bearings, used a tiny screwdriver to remove the seal, and repacked them. Using the correct tools keeps the bearing serviceable.

I'll be there when you have the old style rings in stock and when you get some Radiator Overflow Bottles (2) for my GTV6.

Thanks

P.S. I wish someone would post a couple of good photos of that "Milano" Tool.

I will do that tomorrow for you.

Bud - would you mind taking a pic of what you are into? I could use a boost on the learning curve. The car has had - since delivery at the '10 convention - a really annoying jingle which appears to come from the left rear wheel hub assembly. Been all over the suspension including shocks and located sound by using a cardboard tube as a stethoscope...works for engine noises too...

I have a righty tighty one NOS $25+2s&h



Also have 2(two) retainer rings I think I know what they are P#11600 25.651 00....Does anyone need these ??

I'm just reassembling my hub now, and there seems to be another fundamental difference between the earlier and later retainer rings. The earlier notched ring is about 5mm deeper than the later octagon ring, and that 5mm is a tapered section that extends in toward the bearing. Since the bearing is only 37mm deep it looks like there'll be a few mm gap between the bearing and the back side of the new style ring once the ring is bottomed out on the threads. Certainly if I screw it in further to the bottom of the threads, the stake lip would no longer be over the stake notches. Should there be some kind of spacer associated with the new rings? I suppose it just gets torqued down against the bearing and is not staked.

I didn't install the new rings Centerline sent me, so I can't comment on what you have discovered. Sounds very plausible though. Between this potential problem, the torquing problem Brian Shorey has identified and the factory puller tools pulling the bearing apart through the larger hole, I don't think the new style retainer ring is a good idea to employ. The old style-with defined notches- is an extra heavy-duty way of securing the bearing and I think we should stay with it if at all possible. Those fine threads inside the hubs are very precious too. A Dedion axle would be useless without the threads. That says a lot for the proper serviceability of the unit. Hopefully, Centerline can secure some early type rings for us.
