ktm Posted May 11, 2008 Share #13 Posted May 11, 2008 When I spoke to MSA last about this issue, they said they only sell 2 collars, one for the 280z and one for the turbo/2+2. I do not have the part number. To play it safe, order both and use the shorter of the two. Like you said, dropping the tranny is only something you want to do once. I echo this sentiment, unfortunately I've had to drop mine 6 times in the past 1.5 years for various reasons.

Diseazd Posted May 11, 2008 Author Share #14 Posted May 11, 2008 Bo I ordered the 83 turbo collar and it is very short (and as you mentioned doesn't work). I have a 77 5 speed tranny and the sleeve for it is longer than the 71 Z sleeve. I measured the height of the clutch finger tips (distance from the flat surface of the flywheel to the point of the clutch fingers that the TO bearing contacts). The 240mm pressure plate is actually shorter than the original 240z pressure plate. Wouldn't that mean that I need a sleeve that is longer (not shorter) than the 240z sleeve to reach the shorter pressure plate?

Carl Beck Posted May 12, 2008 Share #15 Posted May 12, 2008 Yes. I posted this picture in another thread recently.. The throw-out bearing sleeve (collar) for the 280Z and ZX 2+2 is shorter than the sleeve for the 280Z/ZX, but longer than the original 240Z sleeve. The input shafts on all the Z / ZX transmissions 70-83 are the same length. As mentioned several times above, by several different people - you have to match the Pressure Plate to the Throw-out bearing sleeve. If you are using the 2+2 flywheel - you have to use the 2+2 Pressure Plate - and therefore the 2+2 Throw-out bearing sleeve. The difference between the Coupe and 2+2 Throw-out bearing sleeve is about 10mm. With 200 flywheel HP - the OEM Nissan Clutch for the 2+2 is plenty strong. FWIW, Carl B.

Diseazd Posted May 12, 2008 Author Share #16 Posted May 12, 2008 Carl Motorsports has a 21-2122 for the 75-78 coupe, 79-83 coupe non turbo, and 84-86 turbo.........they also have a 21-2123 for the 75-78 2+2, 79-83 2+2, 82-83 turbo, 84-89 non turbo.......which one of these two items is correct?

Diseazd Posted May 12, 2008 Author Share #17 Posted May 12, 2008 Nix the last question....Garrett at Motorsports said it's the 21-2122, so I ordered it. Thanks everyone so much for your help. Now I'm gonna put her together! Carl ....Brandon(my son) said you e mailed him re the orange 510. Let me tell you it's a screamer.....feels like Road Atlanta! Thanks for your help.

Carl Beck Posted May 12, 2008 Share #18 Posted May 12, 2008 If you are using "a 240mm Exedy clutch and disc" supplied by Motorsports - then I'd use the throw-out bearing sleeve that they recommend. UNLESS others have already found that Motorsports is wrong.If you are using an OEM Nissan 2+2 Pressure Plate - then I'd use the 2+2 throw-out bearing sleeve sourced from Nissan.Since you are using the adjustable slave cylinder from the Series I cars - you might have enough adjustment travel to make up for the 10mm differnce between the two anyway. I can tell you that the 2+2 sleeve, will NOT work with a 280Z/ZX pressure plate..FWIW,Carl B.What is the exact height of the fingers on the Pressure Plate?FWIW,Carl B.

Diseazd Posted May 12, 2008 Author Share #19 Posted May 12, 2008 I'll check the measurement tonight and let you know. Guy Link to comment https://www.classiczcars.com/topic/27642-240-mm-22-turbo-flywheel/?page=2#findComment-247080 Share on other sites More sharing options...
Diseazd Posted May 12, 2008 Author Share #20 Posted May 12, 2008 Carl The distance from flywheel to clutch fingertips (where the TO bearing would contact) is 1 3/4". Hope that helps. Thanks for your efforts. Guy Link to comment https://www.classiczcars.com/topic/27642-240-mm-22-turbo-flywheel/?page=2#findComment-247101 Share on other sites More sharing options...
Carl Beck Posted May 13, 2008 Share #21 Posted May 13, 2008 From my notes: For 1.75" high fingers - the throw-out bearing sleeve should be 28mm. The Part Number is 30501-1C104 (about $18.00 suggested retail from Nissan). 28mm is the distance between the mounting shoulder under the release bearing itself and the flat surface on one of the "ears" where the "throw-out arm" fork rides on the collar itself. Did you say you already had one or two different throw-out bearing sleeves? If so, measure them and let me know what you find.. The ones I had on the workbench where are 28mm, 23mm and 16mm. Running a 280Z Pressure Plate - the 23mm left me with no clutch - the 28mm solved the problem. The 280Z Pressure Plate was 1.75" to the fingers.. FWIW, Carl B.

Diseazd Posted May 13, 2008 Author Share #22 Posted May 13, 2008 Carl I'm getting a measurement of the TO collar (as described in your illustration) from my 77 5 spd approximately 28 mm. Have I got the right collar? Your info and knowledge of the Z always blows me away!

Carl Beck Posted May 13, 2008 Share #23 Posted May 13, 2008 Yes... that should do it...We all learn by doing - and/or - from others that have done it. I learn something here almost every day.Kim Blough is actually the guy that originally supplied many of the measurement years ago - he has a Z recycling facility in Idaho and is a wealth of knowledge...FWIW,Carl B.
