NT 60 Patrol hunting rig project

[Esteban]

Well... Team Ferrari has not had too much luck recently in F1, so probably for a couple of days you shoul switch teams. Team G60 will do it.

You shouldn't require to pump various times to get some action. It should go at first try, and as RiverPatrol tip goes, try to observe if there's a corresponding movement of the linkage coming out of the slave.

Once you sort this out, then check the operation of the clutch disk.

Maybe the other members in Aussie are fans of Red Bull, since they are silent. Most of their Patrols have the hydraulic clutch and can give you some specific pointers on how to properly bleed this system.

And at the end it's going to be a simple issue, I'm sure.

Thanks for the feedback Esteban . It's strange one this problem we're having. Never had this happen to me before (even when I used to work on old Alfa's and Fiat's, yep real sucker for punishment) but like you said it shouldn't be anything major that can't be fixed, just puzzling. But it is odd that we are definitely getting movement at the slave cylinder with no leakage and weirdly, hardly any pedal feel. Will try your idea of reverse bleeding on the weekend and see what happens. I have a feeling that there could be an air pocket inside the master cylinder or that because the clutch plate is stuck to the flywheel that we're getting funny things happening when we try to bleed the system before we have released the (possibly but likely) rusted on clutch plate.

But......the thing is.....If we keep doing this without letting the clutch pedal all the way out we can maintain some feel in the pedal and it doesn't loose any, or much maybe 4-5mm at most is lost, of the travel we are getting in the clutch arm.

If we let the clutch pedal all the way out we loose all pressure at the pedal and the clutch arm movement is greatly reduced. The only way to get pressure back is to pump the pedal again.

This reaction is very curious. It almost seems as if it may be related to the movement of the piston in the master cylinder. From this description it would seem as if the piston were returning too far when the pedal is released. It doesn't seem possible because there is a clip in the master to keep that from happening (see diagram). That's what I would take a look at though. The clutch hydraulic system is pretty simple, there isn't many places for air to stay trapped in the system. If you have gone through a whole bottle of fluid I truly doubt there is any air in the system. It sounds more like a mechanical issue.

I agree, i would double check the clutch rod to master for excessive play.

Gday RiverPatrol, yes it's got me stuffed that's for sure. It's pretty hot outside to work on the car at the moment but I will be taking the master cylinder out again later on and I want to check a few things. Good idea on the spring clip, it is in there but it may be loose enough to cause some trouble so i'll have a look at it and see. I thought that the piston is held in its place with the screw/bolt that comes up from underneath (I think it was part no 7 in your diagram), it goes up in the slot of the piston. I also want to check that when we swapped the master cylinder with the metal tank and replaced it with the one from the blue patrol that had a plastic tank that we have the correct pushrod in place and to check both push rods side by side to see if there are any obvious issues there.
We're keeping at it, I just want to be able to get her moving and stopping safely so we can bring her into and back out of the workshop easily instead of working outside in the heat. I use the workshop for my business so keeping it in there is not an option.
