pressure plate

a mechanic told me to replace the pressure plate every time i remove
the transmission. how often should a pressure plate be replaced

"Every time you remove the transmission"? Other than for clutch
replacements, why else would you remove the tranny?

And if the clutch is being replaced, pressure plate replacement is a very
good idea. You'd do that at the same time as you'd replace the friction
disc and release bearing.

If the tranny is being removed because of some problem unrelated to the
clutch, then you wouldn't replace the pressure plate unless there were
clutch-related problems or wear in addition to the original reason the
tranny was pulled.

Trying to save a hundred bucks? Not worth it, trust me.

 

Yes, I have some experience of trying to save money by just replacing the
clutch plate...a couple hundred miles later you will have to drop the
gearbox again to replace the pressure plate....do em both together now, you
wil be glad you did.

In the past, I have had shops "turn" the plate at a machine shop. Seemed to
work.

 

The real limitation there is that the springs also take a beating over the
years. The last clutch I did, in my son's Integra, needed work because some
of the springs had worn through the guide flanges.

One general caveat I should mention; ensure before reassembling the clutch
that the disc slides on the shaft freely. A really thin coat of grease is
nice. It is really discouraging to take it apart again because the clutch
won't quite release - guess how I know!

a little anti-seize is better than grease - it's more persistent.

and yes, you're absolutely right on this. not only is a stuck plate
disappointing on reassembly, it's even more disappointing when it
happens progressively over time and thus over-works and eventually
destroys synchros.

 

A good point - I will mend my ways.

 

A sticking friction disc is exactly what happened to me. Lickily I caught
it before the synchros got wrecked.

And the next photos down show a pressure plate with the springs trying to
pop out. How clueless of me not to link to those.
