I would like to thank everyone in this tread who helped me out vary much with my clutch slave cylinder leak problem. It was easier then I thought it would be. I didn't drain the transfer case oil I just unbolted the clutch housing put it on the ground, pushed the thrust bearing back, removed the retainer clip, removed the thrust bearing, removed the old seals, put the new ones in. (which only cost $40.00 Canadian, for both) put the thrust bearing back in, bolted the clutch housing back up on the car, bled the system and presto, no leak. Reassembled the exhaust, attached the rear valiance and I'm done. The whole thing took about 8 hours. ( I was quoted $2000.00 to do the job). I can tell you this. Once it's time to do my clutch, I'll be doing that myself also. Once more. THANKS. Lou | ||

Lou -- do a search on "110860" for more info about plugging/repairing the exhaust sampling ports (110860 is the F PN for a plug that works well IMO). | ||

Those tubes are for gas analysing the exhaust pre-cat, not sure anyone actually does this anymore. I have also broken the tubes and capped mine off at the base. I can then place the non functional tubes back in place if I ever wanted to do concours. -Ben | ||

Joe After a lot of investigation I have determined that the clutch slave cylinder is leaking. I started to remove everything out of the way. I do have one question. There are four little tubes that come off the top of the exhaust system where the pipes bolt up to the headers. They run up the sides of the clutch housing, two on each side. When removing the exhaust I noticed three of them where broken and I busted the four removing the system. I know I can repair them later, just want to know what there for, or can I just plug them. Thanks | ||

Joe Just bleeded some of the fluid out of the system and it looks to be a clear yellow color, and there was no air pops. What do you suggest. | ||

Lou, Do the bleeding first and see the results. That will determine the direction you go. Sure the custom ramps would work. Just make sure though you get the car high enough off the floor to have room to work from underneath, especially when removing the underpinnings to get the exhaust off and then back on. Speaking of exhaust, in the pictures you might have noticed the donuts still stuck to the header ends. You will need all related exhaust donuts replaced if they give you problems during dismantling. Like fractured ones or plain stuck ones you have to scrape off. If you take good measurement, you can save BIG bucks here by getting the donuts from a locale muffler shop. Most of the stock ones are $18 and up, apiece! Also, George Evans or Trutlands have them in stock. Joe | ||

I haven't had a chance to bleed the system yet, but looking at the fluid on the ground it looks clear. | ||

Joe Would it be ok if I just pulled the car back wards up a set of custom car rams. | ||

Lou, Did you ever bleed the system again and if so, what was the color of the fluid that was removed, was there lots of air and will it engage properly? I apologies, but I forgot to mention a couple of other things to hopefully help. You should be sure to really stabilize the whole car with stands under the major frame members. Lift the car 15-20 inches off ground and use 6 jack stands (2 up front and 4 in rear). Lets face it; it will be there for a while if you are going to do it yourself, it took me some time to do it and it was nice to not have to worry about it being unstable. I did more than I thought I needed originally because I went in to see why I was leaking gearbox oil. It was leaking from the 2 rubber "O" rings that seal the pass-thru tubes from the transmission through the motor brace. These are for the impeller shaft and a lubrication tube to the transfer case. Once you are in there, you should look at everything because you won�t want to go back in there again, soon. There is quite a parts list if you go through the whole assembly. I would look at the complete clutch assembly to include TO and pilot bearings, rear main seal, the two �O� ring seals I mentioned, and while your there checking on the slave cylinder, you need some seals to replace there too. I don't think there is a gasket for the transfer case to clutch housing, just sealer. Anyway, let us all now if you need more info. You�ll get it here for sure because of the wealth of knowledge for all models. Here are some more pics of the seals and stuff. Joe     | ||

Lou, Yes, everything can be done from the top and bottom. 1. Remove the complete air filter box assembly and the flat heat shield above the mufflers. 2. Then you will need to remove the rear-inner wheel panels to help make it easier to remove the rear valance. 3. Next unbolt the exhaust at the header connection and the transfer case/clutch housing is completely accessible. Hope this helps, Joe     | ||

Great reference photos Joe -- thanks for posting them. | ||

Thanks for all the help Guys. Does anything have to be removed from under the car or can this all be done from the top? | ||

Luigi, I agree with James. First bleed your system several times to replace the contaminated fluid. I suggest Castrol GT-LMA brake fluid. The LMA stands for Low Moisture Additive, when the fluid gets hot under hard braking it will not boil and create air in the system. If you end up having to rebuild it, it takes some time and parts but it is definitely doable. I rebuilt the clutch and slave cylinder last spring. I have numerous pictures of all stages of work. Here are some pictures of the slave cylinder and clutch housing: After removal:  Slave cylinder:  Reconditioned:  Back in housing:  Hope this helps some, Joe | ||

Luigi - I have scanned the relevant pages of the WSM and e-mailed them to you. Jim S. | ||

Is there anything you can send me (pictures) to follow, and help me remove the clutch housing. Or just start at the back of the car and dig right in. | ||

Luigi - first thing I would do is to bleed the clutch system. In so doing, you will determine whether air got into the system, and whether the leak is a simple thing like the bleeder valve copper washer (unlikely), or the hose (which may rub against something and fail - mine did). The slave cylinder at the clutch housing fails frequently. I have reviewed the WSM and parts book, and it appears that the clutch housing must be removed to repair the slave cylinder. I believe it is something you can accomplish on your own, albeit time and patience will be required. It is relatively easy to remove the clutch housing. Good luck. Jim S. | ||

I haven't had the pleasure (yet), but it's the kind of project that I wouldn't undertake without an SPC and WSM. | ||

Is it someting I can replace myself? And has anyone done it. | ||

Lou -- The TR hydraulic slave cylinder is internal to the bell housing (in the area of the throw-out bearing, concentric with the clutch shaft). Sorry to hear about your problem, but a clutch-ectomy every decade or two is probably unavoidable. | ||

Took my 87TR out for the first time this year. We just hit a high of 50deg's and I couldn't wait any more. I noticed my clutch pedal started to lose pressure and I had a hard time shifting gears. I had to pump the pedal, so I got it back in the garage quick. Once in the garage I notice clutch fluid on the ground under the trans. near the back of the car. Is there a hyd. cylinder somewhere back there, tucked up behind something? I can't quite see where its coming from. |
