You made me have to think (I hate that)! Posted by Cmyles [Email] (#1126) [Profile/Gallery] (more from Cmyles) on Sat, 15 May 2010 16:28:55 In Reply to: Re: Does add up, oh yeah, Simon S, Sat, 15 May 2010 14:46:47 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Simon,
Perhaps what I was trying to say was that the bearing shouldn't be spinning under any load when the clutch is engaged, only when it's disengaged. That spring shouldn't apply the kind of pressure that would cause the (spinning) bearing to wear rapidly, if at all. I believe that the spring is just there to support the accordion boot. For a long time Saab C900 slave assemblies didn't have that spring and they worked just fine. All of the other vehicles that I've worked on had no such spring or boot and their bearings retracted clear of the spring fingers. The V4 Saabs had a spring to pull the bearing away form the pressure plate when the slave was depressurized. There's no advantage in holding the bearing against the fingers, even lightly.
But here's what's important: Most of the C900s on the road now have that spring and boot and pretty much no one else is complaining of eating through throw out bearings one after the other. That's why we say that something, somewhere in the system, is preventing this particular slave from compressing easily causing the bearing to continue to spin under enough load to wear it out but not enough to disengage the clutch.
