sick620 Posted April 4, 2013 Report Share Posted April 4, 2013 After moving my 620 to washington the cluch is finally going out. I moved here for college and am limited on tools, I just have some basic hand tools... Im going to order a clutch right now... anybody in tri cities, or semi close to moses lake want to lend me a hand and a jack and a garage? My truck still drives and I can make it you or we could do it out in the street at my house lol.... Unless its a master cylinder, what do you think- My clutch clamps with enough force to burnout, it dosnt slip at all on hills in any gear and its good there... But the pedal releases at the very end of the pedal no matter the adjustment... And a couple times in the summer when the tempature outside got HOT my clutch would slip... Quote Link to comment
cdub42 Posted April 4, 2013 Report Share Posted April 4, 2013 If you was closer to JBLM I'd say bring er on over Quote Link to comment
Dguy210 Posted April 4, 2013 Report Share Posted April 4, 2013 Can you crawl under and check the slave cyl while someone hits the pedal? Would be interesting to see if you are getting the full throw. Quote Link to comment
racerx Posted April 4, 2013 Report Share Posted April 4, 2013 how old is the clutch.. Quote Link to comment
sick620 Posted April 5, 2013 Author Report Share Posted April 5, 2013 I have no idea how old it is.... I have only had the truck a year, Ive never had it apart... Ill check to see if slave is getting full throw... Quote Link to comment
datzenmike Posted April 5, 2013 Report Share Posted April 5, 2013 You mean it releases at the almost full down on the peddle???? If so this could be air in the system. Look at the master... it full of fluid? Fill and loosen the bleeder on the side of the slave. Have someone push down and hold the clutch... fluid will squirt out. Tighten the bleeder and let up on peddle. When up, loosen the bleeder and repeat until all air bubbles stop and fluid is clean flowing. Every 4th try check the master reservoir. DO NOT LET THE RESERVOIR GO DRY. 6 to 8 sets should clear out any air. Peddle should disengage and grip higher up with less peddle travel. Quote Link to comment

sick620 Posted April 6, 2013 Author Report Share Posted April 6, 2013 when I push the clutch down and release it in gear to start going it engages at the very end of its travel... fluid level is good but its pretty black... Ive put a new slave cylinder on when I got it, and the master dosnt look very old either... Could It just be that it needs bled? I bled the shit out of it when I installed it... I thought that a bad bleed would cause issues getting in gear "shifting" not make it slip or release any later? am I wrong? Quote Link to comment
datzenmike Posted April 6, 2013 Report Share Posted April 6, 2013 We're talking at odds here. At the end of it's travel? Are you saying the peddle is almost all the way UP? when it engages? Quote Link to comment
HRH Posted April 7, 2013 Report Share Posted April 7, 2013 If you can burnout, chances are it's not a clutch. Otherwise you'd have an odd noise, no forward progress and lots of nasty smells. Quote Link to comment
sick620 Posted April 7, 2013 Author Report Share Posted April 7, 2013 Mike thats correct... I was thinking it could be the pressure plate is old and weak, and the hot summer temperatures make it slip because they make it even weaker? Quote Link to comment
HRH Posted April 7, 2013 Report Share Posted April 7, 2013 Step 1: Get under the truck, have someone push the clutch in, see if you have normal travel of the clutch fork. Pay close attention to the rubber line also, which could very easily be swelling and causing a pressure drop. If it's not making full travel, then check into bad slave cylinder (rebuild it) or bad master cylinder (rebuild it). Step 2: Put it in third gear and try to accelerate from 25 mph. If the engine speeds up but the speedo doesn't, then you have a clutch problem. If it bogs and takes forever to start accelerating, your clutch is fine. Quote Link to comment
datzenmike Posted April 7, 2013 Report Share Posted April 7, 2013 Matt, if the line was soft or there was a lack of pressure to the slave wouldn't the peddle have to travel all the way to the floor to disengage and engage the clutch. He said it engages with the peddle lifted almost all the way up. Quote Link to comment
dr.feltersnatch Posted April 7, 2013 Report Share Posted April 7, 2013 But the pedal releases at the very end of the pedal no matter the adjustment...how did you adjust it? at the peddle or the slave cyl? Quote Link to comment
datzenmike Posted April 7, 2013 Report Share Posted April 7, 2013 Make sure that your peddle has about 1/16" of free play in it. Just push lightly on the peddle with your thumb. It should move easily against the spring under the dash and then engage the master and become firm. The push rod is up under the dash where the peddle meets it. There is a clevis pin to rempve and a lock nut to back off. Turn the push rod to shorten it and test the free play. When you get it where you want tighten the lock nut and instal the pin. Don't forget the clip to hold the pin in place. Quote Link to comment
banzai510(hainz) Posted April 7, 2013 Report Share Posted April 7, 2013 the later Datsuns there is no real adjustment. the 510s 521 and maybe early 620s had a threaded rod on the slave and the trans fork arm had a hole throw it. Just bleed the system. Hopefyully the rod that was in the slave cylinder was the correct size and not too long. thus pushing in on the clutch when its fully in the slave. Quote Link to comment
HRH Posted April 7, 2013 Report Share Posted April 7, 2013 Either way, it should be something simple. And peddle is for peddling wares. Pedal is for clutch pedal, killing me here guys! :D 1 Quote Link to comment

izzo Posted April 7, 2013 Report Share Posted April 7, 2013 This is the kinda shit that happens when you go creeping around neighborhoods all pedo like.... constantly disengaging / engaging the clutch.... Nomopedo in the tricities area son. 1 Quote Link to comment

sick620 Posted April 7, 2013 Author Report Share Posted April 7, 2013 I put a new slave on the truck when I got it, off of a 200sx, reason being is my tranny is from a 200sx, do you think that could be a problem for some reason? Quote Link to comment
sick620 Posted May 15, 2013 Author Report Share Posted May 15, 2013 ok I ordered in a master cylinder and a slave cylinder and some ho's ;) the old ho's wouldn't cum off so I couldnt put that on, but the Original ho's was pretty wet and lubricated and not too cracked out so I let that be. My slave looked pretty beat up so It was replaced with a new slave that I can beat on and abuse... my master looked to be functioning and shafting pretty good still, but I drafted the new master to take its place. one thing to note is that the ho's was kinda kinky, and I think the ho's was not allowing the flow to cum through. After a quick test ride everything was releasing at mid pedal and I shifted it hard into gear a few times and got some chirp at the back tires... I think we have success and the ratsun gods will be proud! 2 Quote Link to comment
