Arne Posted March 15, 2006 Share #1 Posted March 15, 2006 I need some info on the return spring that mounts on the clutch slave cylinder. Not sure which cars came with this, but the early 240Zs did at least. I'm almost done gathering my parts to swap in a Type A 4 speed instead of the factory automatic. But I don't have that spring, nor do I see it available anywhere (catalogs or websites). Can anyone give me the dimensions and approximate tension rate on one so that I can look for an alternative?

240ZX Posted March 15, 2006 Share #2 Posted March 15, 2006 Arne, If you get tired of searching for an OEM spring, you may consider an off-the-shelf tension spring....S.S. would be prefered. Measure the distance between the two attach point, with the clutch released, and subtract approximately 1/2" (maybe a little more). Sould be able to find a spring to fit at any good hardware store or do an internet search for springs. When I was redoing my Z, I replaced the two throttle return spring with S.S. springs and chose springs that had slightly less tension than did the stock spring, so my pedal pressure was slightly less. Anyway, I chose the S.S. spring for two other reasons besides get less tension....won't rust and they certainly look better too!

Arne Posted March 15, 2006 Author Share #3 Posted March 15, 2006 I'd be happy to use a non-OEM spring, but since none of this is in the car yet I can't accurately measure it all. I was kinda hoping someone might have one they could measure for me so I can get it ahead of time.

Mat M Posted March 17, 2006 Share #7 Posted March 17, 2006 Here you go Arne! As far as I can tell, the unsprung length of the SC spring is around 3 1/2 inches(out-to-out), and the diameter is about 1/2-5/8. I had to drill a pilot hole in the casing of the SC because this VB part didn't have a way to attach the spring.

mgmoreau Posted August 22, 2008 Share #8 Posted August 22, 2008 I just purchased an aftermarket slave cylinder today. The new cylinder does not have a flange with the hole for the spring. I noticed on the pictures above posted by Mat that his does not appear to have this flange on it. Can anyone give me some guidance on this? I have a 72 240Z 4 spd mfg 3/72. Do I have the wrong slave cylinder? Thanks for any help I can get on this issue.

Curtis240Z Posted August 22, 2008 Share #9 Posted August 22, 2008 mgmoreau you have a later style slave cylinder in hand typically used on the 280Zs. Link to comment https://www.classiczcars.com/topic/19220-clutch-slave-return-spring/#findComment-257601 Share on other sites More sharing options...
ozconnection Posted August 22, 2008 Share #10 Posted August 22, 2008 Never used a clutch return spring in my car when I changed from auto to manual trans. Clutch pedal returned beautifully without it. Lighter pedal too, if that means anything to anyone.

sblake01 Posted August 22, 2008 Share #11 Posted August 22, 2008 I believe 8/71 was the cutoff date for the type A trans that would have used the spring on the release lever.

Arne Posted August 22, 2008 Author Share #12 Posted August 22, 2008 I believe Stephen is correct. The return spring was only used on the early cars with the adjustable slave pushrod.
