bestlowrida Posted October 5, 2012 Share Posted October 5, 2012 (edited) Hey guys, I been searching around but didn't find anything. I was driving around and the car stalled, and shut off. I started it up and it would not go into gear, it would just choke and stall out, I played with it for 15 minutes and just pushed it into a parking spot. I haven't been able to look at it just yet but I had a similar problem with this on my 240sx, it was the slave cylinder. You guys have any ideas? Thanks in advance! edit:car is a 240z with a 5 speed manual, drove the car fine up until now. Edited October 5, 2012 by bestlowrida Quote Link to comment Share on other sites More sharing options...
OldAndyAndTheSea Posted October 5, 2012 Share Posted October 5, 2012 (edited) On our clutch systems, failure can be traced (but is not limited) to a few sources. Clutch Master Cylinder (most likely you will see a leak if this is the case) Hydraulic line breakage/leak (again look for leaks) Clutch slave cylinder (may leak fluid, or may just no longer function properly, I'd watch as a friend pressed the pedal to confirm travel.) That being said, What do you mean the car stalled out? Due to user error (you)? or was it something mechanical feeling? Like pressure plate or throw out bearing failure?

bestlowrida Posted October 5, 2012 Author Share Posted October 5, 2012 I downshifted to 2nd gear to pull into the parking lot and after I let off the clutch the car stalled and cut off. It was pretty crazy, I guess the first thing I can check is the fluid and the get underneath her and see what the clutch and the lines are looking like, sucks its in a dark gravel yard lol.

loy Posted October 6, 2012 Share Posted October 6, 2012 (edited) Wish I could help but I'm in Seattle for the week. If you still haven't fixed it I could look at it when i get back. Edited October 6, 2012 by loy Quote Link to comment Share on other sites More sharing options...

bestlowrida Posted October 8, 2012 Author Share Posted October 8, 2012 So I had a few minutes to go check out the car and there was fluid in the reservoir. It was really dirty similar to this I had my wife get in the car and push on the clutch and try to get it into gear but still would just stall out, even if you push down on the clutch alone it will try to stall. I notice the slave clutch wouldn't move or do anything this is what it looks like. Does this look normal anyone? Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted October 8, 2012 Share Posted October 8, 2012 Are you sure that is the clutch master cylinder? The clutch master cylinder is under the little door to the side of the hood. Any chance you sent us a picture of the brake master cylinder? How does it run in neutral? Can you push the car around? Post a video if you can. The slave looks ok. Have your wife push the pedal while you look under the car and see if the clutch fork moves. Look for wires under the dash that could be getting pinched or grounded out when you push the clutch pedal. Quote Link to comment Share on other sites More sharing options...

I notice the slave clutch wouldn't move or do anything this is what it looks like. Does this look normal anyone? Your clutch slave looks normal. The threaded rod with the nut on it should move when the pedal is pressed. But there's no reason for the engine to "stall" when you press the clutch pedal. Maybe you're pressing the brake pedal at the same time, and you actually have a brake booster vacuum leak. Start the engine and press the brake pedal without touching the gear shift lever or the clutch pedal. The fact that you didn't mention grinding is odd also, if the engine is running and the slave was bad, normally you would just get grinding and engine RPM would not even be affected.

bestlowrida Posted October 9, 2012 Author Share Posted October 9, 2012 (edited) Well today I took my wife out again for more testing. I had her press the clutch pedal down while I was under the car looking around. The slave clutch was moving while she pressed the pedal down. Everything was working as normal the car actually moved! While the motor was turned on in neutral, I did hear some grinding noise but when I pressed the clutch pedal the noise would go away, I should make a video( the wife said the car sounded like that when we got it but I'm not sure loll I would of noticed). So all I gathered so far is my car works sometimes when it hasn't been driven in a couple days but will not engage in gear after a short trip. I hope its not the transmission. I'm pretty stuck right now I haven't had much transmission problems in the past, can anybody shed some light? I will make a video in the next day or so thanks~!

NewZed Posted October 9, 2012 Share Posted October 9, 2012 Peel the rubber boot off of the slave cylinder and see if there's fluid inside. It might be on the edge of going bad. It looks pretty old. Quote Link to comment Share on other sites More sharing options...
bestlowrida Posted October 9, 2012 Author Share Posted October 9, 2012 ^ good point I will check that out, I hope that is the culprit. thanks Quote Link to comment Share on other sites More sharing options...
stravi757 Posted October 9, 2012 Share Posted October 9, 2012 Does the car shift through gears easily when parked? If all of the clutch hydraulic components seem to be in good order then another thing to consider could be the clutch fork return spring(you showed us a picture of your brake master cylinder not you clutch master cylinder BTW).

Yeah lol I took the wrong picture. Does the clutch fork return springs go bad often? Guess that is located in the transmission? Sorry about all my noobness.It did go into gear when parked and turned off, but when turned on it would sometimes go into gear and sometimes not and act like it wanted to cut off. I might just give up and push it across the street to the Nissan dealer lol. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted October 9, 2012 Share Posted October 9, 2012 That's right - the return spring IS missing. I don't think it is the problem, but you are right. I guess the pressure plate is acting as his return spring. Lowrida, there should be a spring between the little hole in the slave cylinder housing and the little hole in the end of the clutch fork. Any old spring that fits would do. However, this shouldn't affect the ability of the engine to run... Quote Link to comment Share on other sites More sharing options...

I might just give up and push it across the street to the Nissan dealer lol. I dont think its a common problem, but I have had it happen to me. It is inside the transmission bell housing. Its a metal clip that attaches to the inside if the clutch fork(clutch fork is what your clutch slave cylinder is pushing), and it sort of snaps onto the pivot ball. Luckily I needed a new clutch anyways so it wasnt like I took the tranny out for no reason. but I was completely confused when trying to figure out what the problem was with my clutch until I pulled the transmission to find that the return spring on the clutch fork came out of place causing me to have none, to minimal clutch disengagement.

JSM Posted October 10, 2012 Share Posted October 10, 2012 (edited) It's possible the clutch fork broke too. I was shocked when I saw it. Edited October 10, 2012 by JSM Quote Link to comment Share on other sites More sharing options...

Hopefully this will fix the problem, I'll find a spring laying around here in this BMW parts dept I work I'm sure we have some around here some were.

AkRev Posted October 10, 2012 Share Posted October 10, 2012 (edited) Once I had an old clutch lose one of its contact pads (broke off the rivets) had similar problems that you are describing except the part about wanting to move in neutral.

Ouch! Hope that isn't the case with me. Quote Link to comment Share on other sites More sharing options...
