GTC fuel pump and clutch work

While sorting out my clutch hydraulic system, I found a leak where the steel pressure line connects at the master cylinder, the flare and tube were damaged and not sealing, so I replaced the whole line. This tube has two different flares; the one at the master is an ISO/DIN type bubble flare, 115 de...

Re: New slave cylinder failure

Steve: In continuing our clutch discussion, you want to adjust the free play at the master (up under the dash) to about 1/8- 1/4 " at the pedal. You do not need more as all additional play does is reduce the overall clutch disengagement. As long as you have some free play at the master, you are fin...

Re: New slave cylinder failure

Tom, I believe you are correct, thinking back a few weeks I found quite a bit of clearance between the pedal rod and the master cylinder piston, so not questioning it, I adjusted the excessive clearance out, so maybe the master cylinder was not fully retracting causing the slave to not fully retract...

Re: New slave cylinder failure

What would prevent the slave piston from fully retracting? a miss-adjustment of the pedal plunger at the master? some other problem with the master?
Sorry about the multiple posts, but any advice would be appreciated.

Best Regards, --Tom

Re: New slave cylinder failure

I stand corrected about a "sleeve" being forced out, there is no "sleeve" it's just the boot seal groove machined in the body of the slave cylinder, an optical illussion brought on by my ingnorance, so why was the piston forced out?

New slave cylinder failure

As some readers have noticed, I recently did a clutch job on my 1968 330 GTC, just prior to that I had a leaking slave cylinder that I replaced with a new one bought from one of the usual suppliers. Attached are photos of the failure which shows the sleeve forced out of the housing with the piston a...

Re: Belated introduction and thanks

Kerry, thanks for the torque values. Tom W, I would like to attend the Concourse on Thursday, I hear it's open to the public. I would like to meet some like-minded enthusiast but I am concerned that it will be mostly newer (post 1980) cars. what can I expect? I'm working hard to get my car in good e...

Re: Belated introduction and thanks

Thank you for the welcome Tom, and the tip on removing the horn button. In regards to the flywheel and pressure plate tourque values, I suppose I can use about 25 ft Lbs, which is about right for the 8mm bolts but if there is some factory value, I'd like to apply it. Thanks again for this resource, ...

GTC revival

Attached are some progress photos of the revival of a newly aquired GTC. I'm doing a clutch job and the flywheel needs resurfacing, it looks worse than it is and I'll bet no more than .010" will be needed to clean it up. Notice the ring gear, extremely worn, each tooth is 1/2 way worn through into 1...

Belated introduction and thanks

I'd like to first thank Tom Yang and all the contributors to this website, it has been invaluable to me in the last several weeks as I massage my newly acquired 330. The car is an early 1968 330 GTC, I bought it from a private party in July of this year. The good news is this car is very original an...
