Clutch Had master and slave cylinder replaced now finding clutch slipping is there an adjustment?

stick shifts are my love. for over 50 years,
ok if the slave cycl released 100% does it? ( look and see it fully retracted)
the clutch is bad if it slips. (linkage /slave good)
no matter what car it is.
that is right warm clutches slip more hot.
a physics thing. (disk surfaces)
here is what can be bad. (all)
bad throw out bearing actual or it sticks from worn out pinon surfaces.
bad PP bad pressure plate, spring weak.
bad DISK , worn thin it hits brass rivets and SLIPS
oil on disk from bad seal front end of tranny
front of tranny pinion shaft a wreck, galled and rusted. and makes the throwout bearing stick and not release.
(all the above is moot, if slave is ok, and master cyc.
moot in the the transmission is now pulled and all above is discovered. and in truth all is just changed out 3 part klt.
done many even 4wd a 10 hour job on those.
first one done was 1964. by me and before that motorcycles and after too.
hint #2 (other) on manual linkage , no slave
the clutch free play must be kept to spec or 1/2" or clutch will slip ignored say for years.

check the slave cylinder adjustment as normally there is no adjustment on the piston rod
There should be about 1/4 " free play between rod and throw out arm
the pivot bolt for the throw out arm should never be adjusted
what you have indicates air in the system or a faulty clutch master cylinder
you can get the clutch slipping indication if the compensating port in the master cylinder is blocked which holds the fluid in the system and keeps the clutch from fulling engaging
no resistance is air in the system and that can be from a faulty master cylinder

check the push rod coming out of the slave cylinder and see if there is a threaded section of bolt into the 1/2 ball at the clutch throw out arm. If it is a one piece rod with no thread then there is no adjustment. With this application if there is a problem indicated by a slipping clutch or the pedal has to come well off the floor before engaging, the cheapest fix is to replace the clutch master cylinder as the compensating port is normally the culprit. If it is adjustable then the adjustment is with the rod pushed fully into the slave cylinder there should be about 1/2 inch between the clutch throw out arm and the 1/2 ball Worst case if you have this adjustment and the slave cylinder piston will readily return fully into the cylinder then you will have to consider the clutch

Hi Timothy, The clutch plate is fitted between the gearbox and the engine. Adjustment is carried out by lengthening or shortening the push rod. Some manufactures have adjustments between the slave cylinder and the clutch folk (underneath the vehicle) while others have adjustments between the top of the clutch pedal and the master cylinder, and others require replacement of the rod with shorter or longer, depending if the clutch is engaging to low or too high. If the clutch is slipping it will probably be too late for adjustment and require replacement of the clutch plate and possibly the clutch cover (pressure plate) and maybe the thrust bearing, Regards John

Given what you're describing, I'd say that you air in the hydraulic system. Did you bench bleed the master and slave before installing them? If you can get a hold of a vacuum bleeder, you can simply do a fluid flush/exchange using it. Good luck! Sometimes getting those pockets of air out can be quite time consuming!

The whole idea behind the Hydralic Clutch is there is no adjustment.If the clutch is slipping then you need a new one.If you are having trouble getting it into gear then you may have a bad clutch master and or slave cylinder.Let me know if i can help.

YOU HAVE HYDRALIC CLUTCH WHICH IS A CLUTCH MASTER CYLINDER WITH SLAVE CYLINDER.IF YOU HAVING CLUTCH PROBLEMS.CLUTCH IS WORN AND SLIPPING OR YOU HAVE LOW FLUID LEVEL IN CLUTCH MASTER CYLINDER.WHICH CAUSES AIR GET IN HYDRALIC SYSTEM.CAUSING CLUTCH PROBLEMS.IF CLUTCH MASTER CYLINDER IS LOW ON FLUID.CHECK HYDRALIC LINE ON SLAVE CYLINDER TO CLUTCH MASTER CYLINDER FOR FLUID LEAKS.

Replace both clutch slave and master cylinders, and bleed well. I've also had this happen.

Sorry, there are no adjustments on your vehicle., The clutch is activated via hydraulic pressure. The master and slave cylinders are "self-adjusting". If the clutch is slipping, you are going to need to pull the trans and replace the clutch assembly. Changing the hydraulics will not help a slipping clutch at all.

Thanks for choosing FixYa for advice!

Hi Jackiaria

Unfortunately you have a hydraulic clutch, which is self adjusting on your car.

The problem you are experiencing is the excessive wear to your clutch, or oil contamination on the clutch plate.

Both these problems can only be fully diagnosed once the gearbox is removed and the clutch is inspected.
There is also a possibility of excessive wear, or scoring, on the flywheel surface, the longer you drive the vehicle with a slipping clutch, possibly requiring the flywheel to be skimmed.

Shop around for a best price, and a trustworthy garage !

Good Luck !

A FixYa rating would be Nice....Thanks.....John.
