TC differential

[Franz]

Hello, I need some help for the rear axle for my TC.

My car grows up in Australia and I think in the unknown last 70 years the differential was broken and they changed it to a Holden one. The last owner in Germany died before I bought the car, so I can't ask him. I got with the car a lot of bills and papers, so I think to know that it is from Holden. I found also a bill from custom made half shafts because have different teeth.

In this Holden differential the part where you mount the prop shaft is not in the center. It is some centimeter to the right side and so the prop shaft tries to pull the rear axle to the right side. I fixed the front parts from the rear springs.

So I'm looking or a TC differential and hope someone can help me to find one.

I also read that it is possible to use a Morris Minor differential (pumpkin), but have to make a lot of machine things I don't know how to do.

Hello from Vienna

Hopefully someone has a spare. I know you can buy them from Roger Furneaux and Doug Pelton but they will not be cheap. The Morris conversion does require machining the differential but no modification to the TC axle housing. You have to remove material from the mating face of the differential housing to move the center of the spider gears farther into the axle. Then drill some new holes, and make a stiffening ring to go onto the differential to make up for the metal you took off the back.

Someone here did a write-up on the conversion but I can't remember who it was.

Thank you Steve,

I prefer the original differential, how much will it cost when I find one

hello Franz - it is possible that somebody has a spare one, but only because it is broken in some way!

I have enough parts to build you a "new" differential, but as Steve says, it is not cheap...because the cause of failure is often breakage of the centre housing, that the Crownwheel bolts to, I have had them re-made from billet steel, These alone cost 450GBP, although I also have some repaired ones for 150GBP.

A complete diff. rebuilt with new gears and taper-roller bearings is thus 1300GBP or 1000GBP according to centre housing

If anybody has a spare diff. hiding in their garage, we would like to know!

Hello Roger,

some minutes ago I wrote you a mail about this, remembered your company, I bought some ago parts from you, everything was perfect.

Thank you, I will think about, because I also need new half shafts and rear hubs.

What ratio will the differential have ?

Excuse my english is not perfect.

Thank you Carl, very interesting, but I don’t know someone who can make this for me.
So I prefer to buy a original TC one.

Terry Sanders wrote that a very long time ago: he talks about visiting scrapyards to salvage diffs. from what are now long-extinct British cars! I have new CW&Ps in ratios of 8/41, 8/39, 8/37 and even 9/39 (a new high ratio I have had specially made, ideal for supercharged cars and Q-type replicas, which are much lighter than standard cars)
