Does anyone know if there is a cross reference part to another vehicle for a 1985 Mondial QV - clutch Slave Cylinder? Such as from Alfa Romeo? Ferrari part number is: 107867 ----- I know there is a cross reference for the clutch master cylinder, to an Alfa Romeo and is about 25% of the price for the identical Ferrari labelled part... Thanks Mike
In 2012 I paid about $75 for a clutch slave cylinder kit from AW Imports. Number was 07867KIT and this was for my 87 Mondial. Check with them. CB
I got the seals from Guido a few years ago. Didn't need them at the time but figured if they were available and inexpensive why not? Used them last year and they worked perfectly! Thanks Guido!
Why is the Mondial slave cylinder prone to failure, or at least that is what I hear, it is oft cited as one of the areas to be proactive with. Is it simply the seals perish, or is there some design flaw?
I would say location....it is between the exhaust manifold and the firewall. Ventilation in that area is probably less than ideal compared to the rear bank. I have a theory that the flywheel sensor for bank 5-8 (which is mere inches from the clutch slave) is more prone to failure than the one for either the tach or bank 1-4 because heat can degrade magnets...certainly the heat will play havoc on seals as well.
Also, I have noticed that the hose from the slave cylinder is a stainless braided one, covered with a black plastic outer cover (mine is flaking away so I can see the braided hose). This would also be subject to the heat, and mine is original. I think replacement hoses vary greatly in price as some just use a regular brake hose, rather than the braided hose? On the other hand they may all just use brake hose and charge different prices, so does anyone have a source for one that is confirmed to be braided and true OEM style?
You need to replace the boot or your new seals will fail prematurely, if buying just the seals, and that's the catch because boot is not sold separately and there is no match
My hose failed during an up shift and the car limped home in first gear. It was a rubber one and was obviously over cooked. I would recommend a SS braided replacement. Brock
Ok folks, thanks for the seal kit suggestions/offers.... However back to the.original question, is there a cross reference part available from another car?
Brock, you have confirmed my concern re: a plain rubber brake hose, assuming you replaced the hose with the correct replacement, where did you get the ss braided hose?
Unfortunately when it busted I was still living in Las Vegas and the car had been moved ahead of me to CO. The gentleman who was storing it for me (and was driving it when it failed) had a hydraulic shop make a replacement. It isn't braided SS or rubber but is a thermoplastic combo of sorts....Sad to say, I don't have any further details other than it is holding up well after 5 years with no signs of degradation.
Under NO circumstances use the Alpha parts. EYE did use them, for both the master and slave cylinder. It led to catastrophic failure of the entire system. At 90F and 8,000rpm I believe an hydraulic parasitic resonance did the following three things. 1) Scattered the clutch plate; 2) destroyed the slave cylinder; and 3) destroyed the master cylinder all at the very same time. I installed rebuilt hydraulic F parts myself [an heroic effort in and of itself] and my local wrench did the clutch plate thing. All at reasonable prices. I also believe you CAN use Alpha parts if you intend only to do parades or GT cruising. Which, actually, is all you need to do! Specifically, I ran my 1986 3.2 through a 1/2 mile speed trial four times. Each time shifting first at 7,500 rpm. Then 7,000 rpm; then 6,500 rpm. Then 6,000 rpm. The fastest time I achieved was shifting at 6,000 rpms at 115 mph. All the other shift points were slower. But not by much. All runs were within 1.5 mph. I believe my Alpha parts would have held up with shift points at 6,000 rpms. Perhaps even 6,500. But clearly not at the red line. Which, it turns out, is simple theatrics anyway.
I change that seal in the slave cilinder every 2 years....its easy to do and the seal is cheap. Also the brake fluid has no change to be contaminated with water. Guido
Guido, another kit left? While everything is out of the car. Mine is a 1982 Mondial 8 US model. Best Jurgen
