Just picked up on this. Do you mean with a manual gearbox, or are you saying the ratios are shorter than normal?marc61 wrote: I’m now a very happy chap to be driving an XM again and to have a manual ES9 thats geared like a sports car is brilliant

Re: A conversion...
Not sure I know what normal is in terms of gear ratios for a manual ES9, but it accelerates real quick especially from 70-100 in fifth.

Re: A conversion...
The standard ES9 manual XM gearing is in my opinion a little short, you certainly notice that 5th gear is shorter than 4th on the automatic. It could do with all the ratios (or at least 5th gear) lengthening by about 15% to allow more relaxed cruising on European motorways.
I have not found much information about alternate gear sets for the ML5, although I think that the diesel versions have longer gearing.

Re: A conversion...
Somewhere in the shed Paul (citroenxm) has a recovered ML6 box.
It is the later 6 speed variant of the ML5.
There are quite a few technical issues about using it in an XM.
Some time ago I looked at the gear ratios for quite a few of the PSA boxes.
Surprised to find very little difference between petrol and diesel versions.
Also looked at crown wheel ratios to lengthen the gearing.
Seems to me quite a bit of modern improved economy comes from ratio lengthening.

Re: A conversion...
The ML6 uses a cable and colllar lift for reverse as its back up next to first in that box.. so that would be the first hurdle to jump if fitting it straight into the car..

Re: A conversion...
I am halfway through completing this job on my ES9 V6. Done the easy bit; engine gearbox out swapped the gearboxes etc, new clutch. Now about to enter the world of pain of gear leaver cables and hydraulic master and slave set ups! I've pm'd you Paul could really use picking your brains!!!

Re: A conversion...
Quick update. I started this last October but then got distracted by a bathroom refit that was at least inside when the weather turned! Fitted the manual gear linkage yesterday: Major discovery: the Pug 406 gear-linkage fits and works superbly with no modification to the mechanism! Just needs a minor mod to the gearstick if you want to fit the XM wooden gear knob.
Now the bad news. My complete sealed XM 2.5TD clutch master/slave has got a fractured pipe color on the master cylinder, so now looking for a complete replacement. Can anybody help?

Re: A conversion...
Hi James,
Can't help with a replacement unfortunately, but as a side note, does that mean you have an intact clutch fluid reservoir that might be going spare assuming you find a replacement? No reason for asking *whistle*
Thanks,
Miah

Re: A conversion...
Not at the moment. Midway through converting to Xantia type bleedable system! Xantia master cylinder installed and 406 V6 slave along lovely metal pipework. Waiting to bleed it as I've had to buy a vacuum break bleeder that hasn't arrived yet. Hoping all of this will work with XM reservoir. If it all works pictures to follow.

Could you not have filled the system from the slave cylinder? That should ensure a complete fill.jamesnoble wrote:Not at the moment. Midway through converting to Xantia type bleedable system!

If not, just use a bit of compressed air to pressurise the filled fluid reservoir.
A regular open reservoir strikes me as a much better idea than a closed, internally pressurised one, ala Xm 2.5TD.
Are you using brake fluid, or LHM as the hydraulic transfer medium. A tap from the LHM low pressure system to a master cyclinder would have worked, with no reguirement for any reservoir at all. If you want to get really tech-y, use the high pressure LHM system pressure and a doseur valve.
Having just cecked it appears a 406 or C5 master cylinder would have been easier to use as it has a remote reservoir, thus wouldn't have any issue bleeding it and could just use low pressure LHM as the fill.
Now, that's got me thinking for cable operated RHD cars...
Power steering...power brakes...power clutch...
How does the 406 slave cylinder interact with the clutch, is it via an arm, or is it a CSC acting directly onto the release bearing?
