Cable Clutch to Hydraulic conversion on a LHD 7


DB6

Recommended Posts

My '98 Crossflow Caterham has the hydraulic clutch. I'd give Ben a RMSCI a call. Not sure they will have the parts, but he should be able to point you in the right direction.

 

At one point I thought I might have to replace my Master Cylinder, and managed to find this site:

And I think this may be the slave cylinder I have (the blue one)

It's been awhile, and I'd have to look at my Master Cylinder to confirm which model it is.

 

I think the conversion is pretty straight forward. You also might want to search on BlatChat.

Ok here goes, Looking at the photo's I realize that my engine bay is a MESS!!!

 

 

Picture 1 shows the Blue anodized Slave cylinder mounted with spacers to get the right pull lenght. Yellow bush goes into the bellhousing and slave rod protudes thru and attaches with clevis to the clutch arm.

 

Picture 2 shows home made clevis attached to clutch arm.

 

Picture 3 shows the Clutch master cylinder with the braided hose snaking over to the slave cylinder.

 

Hope they help. Tom

Shouldn't be an issue assuming you have a way to anchor the slave cylinder. My bellhousing has a hole that the yellow bushing and slave cylinder are inserted into.

 

The attachment to the clutch arm is the other issue that needs to be addressed but shouldn't be too difficult to remedy if Caterham doesn't have standard parts for it.

Ian,

the car was set up for RHD with a short cable, say 10 inches

When they produced LHD cars the answer from Caterham was to loop a 5 foot plus cable like a big horseshoe, it stretches, it kinks, and eventually it snaps, always in the same place.Some ppl get lucky and run for thousands, others break within a couple of thousans miles.,to the point where they carry spare cables.See the pic I added at the top of the page.My cable had stretched almost 3 inches in 2000 miles.

Thanks for the info.

I've got one of those 5' long 'loops' around the front of the engine. No apparent stretch in 1500 miles so far.

Where do they typically break off? (I don't have quite the same terminal end and nylon 'block' on mine; is that pedal or engine end in your photo?)

thx again

Took a few quick photos of my Crossflow setup. Picture from above the slave cylinder is pretty fuzzy, and the one from below was taken blind, but thought these might help a bit.

The hydraulic setup was on the car when I bought it. At one point I did some internet research on it, and found this:

If you Google "Neal Pulling Slave cylinder" you'll find other companies that sell them.

 

It's not really attached to the bell housing, in that it just sits in that eye on the side of the housing - if that makes any sense.

thx

I guess I see how it 'hangs' there with its nose in the b/h hole, held in place by light tension in the pullrod, but personally wouldn't want it vibrating around all the time; maybe even just JBWeld to hold it firm.

cheers

Ian
