casper1483 Posted April 10, 2012 Share Posted April 10, 2012 Looking for the spring that goes in the gearbox output shaft where the prop goes in, it's a 2.0 5 speed Cih, I've got one in a safe place and can't find it, Doh ! Link to comment Share on other sites More sharing options...
611 Posted April 10, 2012 Share Posted April 10, 2012 i think mine must be in the same safe place :-) Andy Link to comment Share on other sites More sharing options...
MANTAMAN Posted April 11, 2012 Share Posted April 11, 2012 Just an aside, what on earth does this spring do???, cant see any reason for it, the gearbox output shaft is in a fixed position, the prop is held in a fixed position by the rear axle assemble so this spring cant be taking up slack anywhere, i await to be enlightened.....

Shug Posted April 11, 2012 Share Posted April 11, 2012 I'm assuming as there will be some movement in gearbox and rear axle as you drive along its to dampen. I guess its not really necessary. (guess means hope, as I dont have one.....) Link to comment Share on other sites More sharing options...
mantasrme Posted April 11, 2012 Share Posted April 11, 2012 I have a couple of spares here if you want one posting, or want to come collect one. As for its purpose, as the axle goes up and down the propshaft moves in and out on the spline in the back of the gearbox I put the spring down as keeping tension/pressure on the end of the prop so there is no wobble causing wear of the splines. But i could be wrong about the reason, i just refit them as i assume opel had a good reason for it Link to comment Share on other sites More sharing options...
611 Posted April 11, 2012 Share Posted April 11, 2012 I think its also there to stop too much movement front to back on the prop as just replaced the rubber doughnut on my prop and i think if it moved to far forward you could pop the bearing out of the doughnut. Im going to have a rummage about in the garage to see if i can uncover it and if not i will drop you a PM. Thanks Andy Link to comment Share on other sites More sharing options...
casper1483 Posted April 11, 2012 Author Share Posted April 11, 2012 I haven't a clue what it's for either, just know that when I did the 5 speed conversion I forgot to put it in, I ran it for twelve month and its been fine, I put it safe knowing I would be doing a referb some time and I've had a few beers since then and it's long gone,, it must serve a purpose, mantasrme I'll pm you thanks.....

cam.in.head Posted April 11, 2012 Share Posted April 11, 2012 it keeps the blanking cap on the end of the diff pinion shaft in contact with the innermost of the sliding spline.keeping the torque tube bearing centered in the rubber mount.i suppose without it all will work ok but the shaft could bounce around back & forth possibly causing wear or noise ??? like someone said earlier gm fitted it so its there for a reason.
