I have tried covering my clutch cable wheel and cable several different ways but nothing great....just changed my cable and it seems a shame to leave it out in the open like it is.....any good ideas to keep the road grit out? I think Mikey should be working on this but who am to say? Welcome ideas and it just makes sense to protect this vital area from contamination.....thank you for your thoughts,,,,

This is what I installed.
Still get dirty (but maybe a little less).
Better ground clearance for sure.

I bought a CSOB cable and it was rubbish,I had already bought the 914rubber delron roller and its a great part,but after fitting the original cable with proper nylon liner had a huge improvement in pedal feel so don't buy the cheap cable (IMG:style_emoticons/default/headbang.gif) .
IMO make sure you have the rubber boot on the cable and don't use any lube ,stock mounting is fine for road grime even without the plastic cover which I have back on now,however if you have the horizontal TR setup you may pick a bit more grime up but is no cover to fit that.

"VW+Porsche" article from the early '80s , I sourced a factory 916 transaxle, built the horizontal clutch pulley bracket and have run it sans grease with good results . Coco floormats were in !

I’ve had the same thought. My clutch cable seems to break at the wheel. I think it’s because the grease and sand abrade the wires as the tranny is shifted.

I have been told by a 914 expert that the cable ALWAYS breaks at the wheel. Allowing dirt and grime into the roller area and cable/roller contact area just does't make sense to us wear avoidance folks....gotta' be a way with a plastic bubble or something.....I have been using baggies and magnets....not great....there has got to be a solution....thank you,

Yes that was kinda my point about horizontal rollers,the road grime with collect in that area and has no where to go, the stock roller mount will collect less if you don't use grease and reduce cable wear @ that point because that's the weak point due to a fairly tight radius ,the delron roller (914rubber) is a great update as the stock nylon one wears out @ the centre bush and loads the action further...as my old one did.

Horizontal makes sense on a race car that has been severely lowered to aid ground clearnace. Not an issue on cars at or near stock ride height.

No grease on cable. A dab of grease at the wheel center pivot. Wheel needs to rotate.

If you're repeatedly breaking cables -- make sure you have a zero ohm ground connection between body and engine/trans. Otherwise the clutch cable becomes the ground and drastically shortens cable life.

Ok....I am hatching an idea here.....I took a close look at the clutch wheel area today and there is enough room for the little tiny magnets that Harbor Frieght sells all around the wheel...these are rare earth magnets and very strong...so if I put a womens nylon around the wheel and attach with these little magnets I may have a fine screen to help protect the cable and such. Can anyone suggest a better screen material than a woman's nylon? I am thinking 99 cent store for the nylon....Harbor Frieght magnets are $3 tops....I am not giving up on this until my new cable and wheel are protected so hang on......thank you for any input...

If you really need a project, rig up a hydraulic clutch.

No cable to break..

What are we talking about? 10-yr lifespan for a clutch cable? Even if it's 5 - and I'd find that very hard to believe - it's neither an expensive nor hateful replacement job.

And this will not resolve cable stretching, of course, which is a far more-common problem.

Chris designed the horizontal wheel bracket for clearance around his headers. It's not intended for any kind of "safety" or lifespan problems.

I printed a cover a while back but didn't mount it. I tried some clips but they didn't hold it on. Probably should have just used some tiewraps. Here's what it looks like now.

Wow....those last two replies really are thought provoking. Just how significant is the dirt contamination in the life of a cable? Great question....And then the picture of the actual cover is amazing.....I want one of those!! Especially if it was made out of clear plastic or softer clear rubber (hint hint Mark). Anyway.....I am on my way to the fabric store to buy some polyester cloth and see what I can come up with. Thanks you guys,

As much as I think it's a solution seeking a problem, that is great design work and you have at least one interested customer! Great job! I wish I had more time to play . . . Is that done in Inventor? Axis and the way planes are notated look familiar. Maybe some other AutoDesk product?
