Finally ... Repairing a traction gearbox.

Hi Shane,
Would you like to tell us what is so special about this? It looks like a manual trans/axle. A crunch box.

Does this mean that you have finally got stuck into the TA box of your Dad's 11BL?
George, this is why this box is so special!
Shane; Sing out if you need any help!

Oh .... belongs to this.





It's out of my fathers traction. I've been itching to drive this car for about 15years, but it's always had a noise in the gearbox, so we have never been game enough to use it.

seeya,
Shane L.

A friend of mine restored one of those many years ago. He let me have a drive of it. He had fully restored the car , the engine, everything. It was a truely HORRIBLE experience. No synchro in any gear. You had to double clutch it, it was just no fun at all. I'd be taking those cogs out and replacing them with something user friendly.
Something at least with synchro mesh.

:roflmao: You sound like my father. The way they drive is the appeal. I enjoy trying to get double clutching right .... you forgot to mention the heavy steering, pathetic steering lock and drum brakes. It's all lots of fun :dance: :dance: :dance:

George you don't know what you are talking about. They are synchro on 2nd and 3rd. and only non synchro on 1st!
Have a look at Shanes pictures and you can see the synchro drum on the main shaft in between the 2nd and top gear pinions.
If your friends resto was a horrible experience maybe he did what a lot of people used to do and just prettied it up with out doing a proper job on the parts that really count!
I have driven pretty looking tractions that are horrible to drive simply because the approach I outlined was employed. My theory would be to do it all again and to do it properly!

George if you can't drive a crash gearbox with ease you need your license endorsed, like the modern auto girlies! NOT HORRIBLE. With practice it becomes easy.

I learned on an ALL gear crash box, and when I was successful the old man reckoned I still couldn't drive properly because there wasn't a manual advance. Needless to say he learned on something not far removed from a horseless carriage.

I thought you were talking about the CX wagon. We really need a gallery of all of your collection, inside the shed and outside please.

What is it that you people do not understand about synchro on 2nd and 3rd?

But I do understand. I can see the synchro. It's a half-girlie car; there are 1st and 2nd to master. In other prewar vehicles there might be 3 or 4 as well.

The only time one needs to double clutch is changing from 2nd back into first whilst on the move. Thankfully this is never really needed as 2nd is a good strong gear and can haul away from very low speeds. BTW have you ever needed to drive a D with a broken clutch cable? One starts the car with 1st engaged and then it is rev matching to accomplish all changes from then on once moving!

You have just listed all he cars that aren't mine... Mine are the worthless crap. The good ones are other peoples, the traction is my fathers, the 2cv is my mothers, the CX wagon is owned by someone down in Melbourne. The battered crap is mine :D

Those 3 cars are way too nice for me to own.

seeya,

I had the synchros removed from an MG TF. Actually, they just ground off the spiky bits to leave a nice brass ring as a spacer. Much quicker changing gears in a crash box than gears where the synchro is stuffed.

I always double clutch changing down in the 2CV as I can do it at higher revs so it is in 2nd gear for corners. To preserve the revs on corners when turning into another road, I declutch the gearbox halfway through and let the clutch out as I am accelerating.

Kind of a Fred Upstairs dance step playing those two pedals in concert.

Defence of Traction alert!
Heavy steering - yes at parking speeds but perfect at speed. can out handle most cars of the 60's and seventies. Brakes are big and if properly adjusted are fine. You can get through those gears pretty quickly when you get used to it. Got keep that heavy flywheel spinning. They get along fine. Only complaint is the low top gear / and freeways ! ( earmuffs might help) Thats why the four speed conversion was so popular. You should do one for your dad!

A 10x31 crown and pinion addresses the cruising speed issues. It is however a hefty investment and some engine mods would help to improve the performance so that the gear flexibility is not lost. Ask Rob Little what he has done to his Big 15 engine.

Nice replies guys, in my defense I'd forgotten that the lack of synch was only between 1st and 2nd. But it was in about 1977 that Tim registered the car after fully restoring it. That's when I last drove it. That's a darn long time ago.
Tim had FULLY restored everything, the car was showroom condition when he finished it. He personally fixed and re-engineered everything. He even had the white walled tyres. And it was the same colour as Shane's dad's car. He personally re-upholstered it too, he had his own industrial sewing machine. He also spray painted it.
I don't give a crap about having FUN trying to match the speed of the cogs. I'm not a psychic. It just didn't work for me. And you're right Shane, the steering was more like a truck, and the brakes were only just able to pull it up.
We take so many improvements for granted. They are called IMPROVEMENTS for a reason.
So having an all synchro box makes it a 'girlie' thing? that's amazing. While it's true that my grandmother could have mastered the art of driving a 'crunch box', she and her brothers had no option. I just thought it was really annoying, and it really was the only thing that let the car down.

If you fit the original riveted brake linings and properly centralise the shoes to the drums the brakes are excellent. The problem today is that people opt for bonded linings that are way too hard. My original 53 light 15 I had in 1966 was able to pull to a dead halt from 35MPH in 30 feet. They were always noted for having superior brakes to most other motor cars of the day. Sure pedal pressures are higher because the system is unassisted but highly effective in any case.
OMG white wall tyres?? How crass!
