EricB Posted July 27, 2005 Author Share #13 Posted July 27, 2005 hmmmThe thing is the one I got from MSA is a Nabco/Tokico which is the OE supplier of our stock unit... so it's made by the same company with the same application... the fact i bought it at somewhere else than the dealer ought not be an issue - go figure.Rather than messing with the clutch master cylinder rod any further I checked P/Ns and 73 240Z through 81 280ZX have the same slave cylinder (I thought maybe there were different length salve cylinder rods). I thought I might be able to use a longer slave cylinder rod to fix my problem... Since they are all the same length here's what I did this AM:Got a 5/16" diameter 5" lag bolt from home depot ($0.40), cut the threads and head off, ground the ends down so they are hemi-spherical. put a groove in it for the rubber seal to grab onto and presto a new smooth slave cylinder rod that's 1/4"~3/8" longer than the factory one and within 0.1mm of the stock one's diameter.I figure I now have room to adjust in at the clutch pedal as much as I need to to get it perfect. We'll see tonight when I get off work I guess.-e Link to comment Share on other sites More sharing options...

It is possible that an aftermarket "brand" changed rod specifications to allow the MC to 'more or less' fit a range of vehicles to keep price down. So Nissan's version has exactly the right rod, but an aftermarket version, even if made by the OE supplier may have a compromise rod. Just a guess.

sideshowbob Posted July 27, 2005 Share #15 Posted July 27, 2005 Oh... I don't know... how many times did you bleed the system? Just checking the obvious here. How about the clutch pedal free play adjustment? You do know that bleeding the clutch is not the same procedure normally used for brakes, yes? http://www.atlanticz.ca/zclub/techtips/clutchbleed/index.html http://www.atlanticz.ca/zclub/techtips/clutchfreeplay/index.html Link to comment Share on other sites More sharing options...
EricB Posted August 9, 2005 Author Share #16 Posted August 9, 2005 The plot thickens...The threaded rod on the clutch master cylinder I removed from my car measured 4" from the flange that bolts to the firewall to the tip of the rod.The no name Japanese replacement I got at the local auto parts store had a rod that measured 3"3/8 - way too short.The Nabco/Tokico unit that MSA sells is 3" 3/4 longTHat's what I currently have in the car. However the only way to make it work I found was to fab up a longer slave cylinder rod & it isn't perfect. I've got to kill the engine to put the car in reverse.I've got one on order from the local Nissan dealership at $92... It's due in tomorrow - we'll see what size that one is.-e Link to comment Share on other sites More sharing options...
