Hi Mitch, I'd really like this not turn into an engine out although you should be able to sneak the transaxle out on it's own. Probabilities are 1) air in system 2) something wrong between the slave and clutch pressure plate fingers 3) defective clutch slave cylinder. If each slave was...

Hi Mitchell, If there's no visible damage to the seal or piston bore then the slave cylinder should work. If you have three cylinders acting the same way it's hard to point at the slave cylinder being the culprit. That doesn't explain why or how clutch fluid was getting past the seal and into...

Hi Dean, Be prepared to be the center of attention where ever you go the that car, looks fabulous! The front uprights are third generation and began appearing in the post s/n100 CAVs. The upper control arms also changed with the uprights. The front lower a-arms also changed, however the track...

I should add that some clutch master cylinders can be very difficult to bleed by the standard pump the pedal method. Mitchell have you tried vacuum bleeding the clutch circuit? Cheers

Hi Mitchell, By what your describing the clutch slave appears to be properly engaged at rest, if there's no fluid leaking anywhere then there must be air in the clutch circuit. That includes the clutch master possibly. I'd much rather have that be the problem than transaxle out to inspect the...

Hi Tim, Most likely misalignment between the crank and input shaft of the transaxle. Corrected by offset dowels as mentioned above. The internal throw out bearing will give you no problems if properly set up. An external slave cylinder and fork is no less fussy to set up but does look more...

Hi Cletus, My guess is Kellison. Jim Kellison was a major force in the early days of home built modified cars, "Google it Jerry!" I seem to recall seeing an add in the back of an issue of Road&Track around say... 1964-5 with a picture of a car that looks just like yours. The Kellison...

Hi Nick, We had a very similar thing happen here. A new GT40 owner who had recently purchased his car from the owner/builder, drove it a while and then brought it here to solve some cooling issues. Initially I thought air cooling system, incorrect piping to the rad or header tank or a...

Hi Mitchell Sounds like a plan, you will know how much the slave pushrod moved back into it's housing. That length is your available stroke to lift the clutch. Can't wait to hear what you find out. Cheers Ian

Nice work Jim, glad to see hear you're getting some miles on the car. How's the reaction from folks when you're out and about? Cheers Ian

Hi Mitchell, Compare the slave cylinder length in your picture to the length measured from the mounting hole to where the slaves' pushrod would contact the clutch fork inside the transaxle. The distance measured inside the transaxle should shorter than the bare cylinder by almost the length...

HI Mitchell, Lots of things happen you wouldn't imagine, until it does! If you look strait into the hole the clutch slave cylinder presses into, you should be able to see the end of the clutch fork and the small pocket the pin of the slave cylinder seats into centered in your line of sight...

All valid recommendations, especially given the many variables in hydraulic clutch slave actuation and transaxle types. In the case of the OE Audi application we went though in my shop, the complete clutch assembly and slave (just to be safe, it wasn't leaking) were replacred. I was surprised...

Hi Mitchell, When your looking at the clutch slave cylinder out of car, the piston is already fully extended, there is no more available to open the clutch. If the clutch slave cylinder pushrod is not pushed back into its retracted position by the clutch fork you will have no clutch action...

Hi Mitchell Getrag Transaxle? Is it possible the clutch fork inside the bellhousing has become misaligned? If the clutch slave cylinder pushrod doesn't engage the clutch fork there is nothing to hold the clutch piston in its proper resting position to start the action of pushing against the...

" And Peter, if you're on here: Thank you. That was THE most fun I've had all year! " Yes, it would be great to have the GT40 drivers recollection of the spin! Things happen very fast on the track, glad everyone came out OK:) Ian

Hi Paul, Do you have any more information on this pump? Compact size is a definite plus for sure. Is it rebuildable or are installing a brand new part? Used A/C pumps are risky, you could end up doing it all over again. Without an overhaul manual for the pump your next best reference would...

Chris, Neil offered how best to approach to the engine builder on post#14 "I'd approach Lance at Craft Performance with that dyno sheet in hand and ask him (not demand- things can go downhill in a hurry) why the numbers are so far off. Something was not right during that test and the engine...

Hi Steve, the question about the speed range in each gear is valid on the race track. On the street I have to believe you upshift each gear well below the redline, yes? The same goes for these cars. The motor if at all happy running on pump gas it will make tons of torque right off the idle...

Hi Steve, if the biggest concern you have after buying that car is wondering if 1st gear is too tall, you are the luckiest man on the planet! Cheers Ian P.S. no affiliation with the seller:)
