bonvo Posted April 21, 2011 Report Share Posted April 21, 2011 its all good man lol i wasent offended or anything just trying to help a fellow ratsuner i know on my 610 the fork is the way you describe but i have seen 510s with the hole im thinking his fork got swapped at some point and now he needs to get creative Quote Link to comment
turboHLS30 Posted April 21, 2011 Author Report Share Posted April 21, 2011 Well the old slave I pulled out is identical to the two "new" ones I've had. The motor and trans are out of a 240z, would that make a difference? I mean I ordered a 240z slave cylinder. I think the real problem is the fork itself, because the pushrod goes through the hole that is there and causes the piston to overextend and then pour brake fluid everywhere. This is what it's supposed to look like Instead mine has a hole where the slave cylinder pushrod goes through. Quote Link to comment

Bonvo hit it right on ,,, You are not suppose to have a hole there ,,, yes it is a problem ,,, Do you have the correct clutchfork ? or do you think someone drilled it out to put in an "adjustable" slave cylinder push rod ? :) Quote Link to comment
turboHLS30 Posted April 21, 2011 Author Report Share Posted April 21, 2011 That or maybe a transmission swap? Quote Link to comment
datzenmike Posted April 21, 2011 Report Share Posted April 21, 2011 Did you change your post because I don't remember the part about the push rod falling out. Anyway you must have an older transmission or older clutch arm in your '75. You should have the one below on the top. The very bottom one is for the A type 4 speed transmission and the slave push rod has a threaded end and adjusting nut of free play. . Quote Link to comment

The motor and trans are out of a '72 240z if that helps anything. Quote Link to comment
Rob W. Posted April 21, 2011 Report Share Posted April 21, 2011 That type of fork needs a slave with the set-up like has been mentioned usually uses a threaded rod with a couple of nuts. So eitther get a different slave cylinder or change the fork whatever is easier. It's strange that the old one worked at all... Why are you changing it? I missed that part. Use the new seals and rebuild the old one if it worked. Quote Link to comment

What slave cylinder should I order to work with my clutch fork/trans. damn im good lol Not bad at all my friend, thanks for all the help. Quote Link to comment
banzai510(hainz) Posted April 21, 2011 Report Share Posted April 21, 2011 So more or less you just hooked up the hose and pushed the pedal and blow it out the end? since nothing was pushing it back to keep from over extending. Thats what I thought at first but I didnt say anything think n maybe there are bad slaves. I never seen it before. esp if its made in Japan. the threaded ball(12mm) end and with the 12mm Jam nut is usually the early datsuns like the 510. The later Datsun used the fork arm with the indent and just a rod with a rounded end to fit in. Quote Link to comment

They were used on 521 and early 620 trucks and the 510 car. There must be lots laying around from 5 speed swaps. Ask someone here. Quote Link to comment
Rob W. Posted April 21, 2011 Report Share Posted April 21, 2011 I'm not saying this is the right part but this is what it should look like any way.. basically. http://info.rockauto.com/getimage/getimage.php?imagekey=486191&imageurl=http%3A//info.rockauto.com/BeckArnley/BA%25200721258-1.jpg Hope it helps Quote Link to comment
turboHLS30 Posted April 21, 2011 Author Report Share Posted April 21, 2011 That actually looks like it will fit the Z too (As in the whole slave cylinder) Quote Link to comment
Rob W. Posted April 21, 2011 Report Share Posted April 21, 2011 Its a 1972 240z slave according to Rock Auto Quote Link to comment
turboHLS30 Posted April 21, 2011 Author Report Share Posted April 21, 2011 What seems like the easiest thing to do? Quote Link to comment
banzai510(hainz) Posted April 21, 2011 Report Share Posted April 21, 2011 be honest most slave cyl from the 510 to the 240sx will work. Its just the rods might be differt. just clean up the old rod. Thats what I do. I order 77 200sx ones but use my old threaded rod. The truck can be different as the torsion bar can be in the car and hose length.. as in the 521 truckl the hose come out the front.

turboHLS30 Posted April 21, 2011 Author Report Share Posted April 21, 2011 Why is this so difficult? LOL I'll go by Advanced Auto Parts and see if the have one for a Datsun 620 or 510 and see if they have the right one. Quote Link to comment
