Verto to Pre-verto; clutch arm
Turbo Mini Forums

Howdy,

This is easier if I give a bit of backgorund; I've bagged myself a "new" (200-miles old) engine which has been built to the spec I was going to spend the next 2 or 3 years doing, only I've saved the time and effort and a fair wedge of cash getting it now. It has a pre-verto clutch. It's going to replace my "standard" metro-turbo engine, i.e. with a verto clutch.

My problem; I've fab'd my own brace bars; the offside one I'd made with a "little" clearance for the [short verto] clutch arm. The new engine with its longer clutch arm won't clear my brace bar. At this point a picture would be useful but of the several hundred pics I have of the car, none of them show this (and the engine is already out) here's the best I have



my question!
- Has anybody ever tried/ had the need to use the shorter verto clutch arm rather than the longer pre-verto?
- Is the bottom of the clutch arm significantly different between the two? The angle of inclination certainly looks different, but the profile of the end looks similar (I could just check these tonight myself) (verto pre-verto )
- Any ideas on arm travel/ slave cyl. stroke?

As you'd probably guessed, I'd rather keep the shorter verto arm if possible, or maybe even shorten the pre-verto arm, but that depends on arm travel to disengage the clutch. At worst it'll be a new brace bar I suppose.

Cheers!

PS In typing this I've almost convinced myself new brace bars are the way to go!

New brace bar.

you will never get enough lever action with the verto arm on a pre verto clutch. The clutch pedal would be rock hard!!

An expensive solution - sleeve down the bore of the clutch master cylinder and have a custum made piston made to take an appropriate common size seal. With the right size bore the verto arm arm would mimic release bearing travel and foot pressure of the pre-verto.

Otherwise, something I thought about ages ago, it may be possible to completely modify the pedal box to take the cable of the (later) A series Metro vertos. Cable verto arm on Metros is a different angle yet again (so may still have clearance issues) but the cable operation could be so much simpler.

Schrödinger's cat - so which one am I ???

The cable mounting thingy is quite big, not sure it would clear the servo and brace bar

New brace bar for me too.

If something is worth doing, it's worth doing half of.
