cross-reference 6 speed gearbox

[fanch]

Hello
Does anyone know the cross-reference of Caterham 6 speed gearbox parts (pinions, synchro etc) with Ford reference ? (Ford is the donor manufacturer of numerous parts of this gearbox)

Er no. All the parts are bespoke. They were designed by Flotech.

The lack of Ford parts means they do not continually break synchro rings and blocker bars as the Type 9 does.

however, mine knackers the baulk rings and suffers from general crap shifting between 4th and 3rd. Phil has seen it 3 times in the last 2 years. Not great when you really *need* to find 3rd at the 'Ring and you have to reselect 4th. I can't seem to sort this problem, despite having tried a number of different g/box oils.... very frustrating. When cold, it's also a real pain...

Not the best gearbox I've used. Also, although it is fairly close ratio, it could do with being even closer for circuit use. (and yes, I do have a 1.8 k series).

The sequentail box in my clio cup is far slicker...

I've had 4 cars with 6 speeds and every one has been different in feel and quality of change. I don't like the one in the R500 as much as the one in the SLR for example - I have the same issue as you on the 4th to 3rd change - not much fun when you arive at the end of the Revitt Straight and you wrong slot it...mine was rebuilt by Phil just before I bought the car.

I would have thought that Phil would have been able to make them all feel alike once he's reassembled them. That's the frustrating thing. Although the new quaife seq. box does look good. Trouble is, it's difficult to know where to stop on a car that only gets used around 10 times/year!!

Well he's rebuilt 2 of my boxes and it's difficult really to tell the difference pre and post rebuild. I bought a Quaife with the car but sold it on as I have driven cars with these boxes before and they are hellishly noisy.

I've driven the new Quaife 'box (QBE-60G) in a race CSR and its a very nice unit - very slick, very positive and feels bullet proof. However being a straight-cut dog box it ain't the quietest thing around. I did hear a rumour that they were thinking of doing one with helical cut gears (or whatever it is) that should be quieter. Perhaps a word with Quaife?

Could always fot one to the same spec as Caterham will use in the Eurocup this year....what propshaft would you recommend Fcat?

Took me 7 years to break my Quaife sequential. And then it was broken only by a mis calibrated full throttle shift system. Damage was minimal, and the rest of the box was in good order.

If you ahve broken a Caterham 6 speed, I'd suggest not rushing the box quite as much. The reason they feel different is there are options on the lever bias springing, and the syncros behave very differently on different brands/types of oil.

I contacted several seller (Caterham UK, SV in France, B&B (race team in France); but nobody has parts for this gearbox.
I ordered by Westerman in Germany, but I get only one pinion!!!

Who in UK supplies these parts ??

It's not broken, more that the shift quality is ste! It's as if I beat the synchros going from 4th to 3rd. I use redline MTL, but may switch to silkolene Syn5 to see if that improves things. I have the 'race' spring fitted in terms of lever bias...

The box is starting to put me off using the car (which only really gets used at the 'ring these days).

I've heard that R&RT use cheaper baulk rings and they are prone to wear...

PS anyone had any experience in the new 260hp Exige with decent suspension fitted?
