Resurfacing a Pressure Plate ???

Can a clutch pressure plate on a tractor be resurfaced? I have read a number of discussions on various internet forums, some saying definitely NO while others reply that it can be done. These forums though have been automotive ones so they're dealing with much higher revs, etc. I'm guessing maybe ten-thou would do the trick. Any opinions from tractor guys?
 
I had one done one time that had the clutch material rusted to it. The machine shop said they had never done one but would try. I think they said they took off .003 just to clean the surface.
The PP is still holding up after 5 or 6 years.
 
Clutch rebuild shops do it all the time. We used to do the facings and carry the plate and flywheel to them to true up.

It is possible to totally rebuild a pressure plate, but the only reason you would have that done is if you have a tractor that is old enough that NO new parts are available.
 
Overall, I see no reason why one could not be resurfaced, but the economy of it may be another issue.
First issue would be disassembly for the purpose of rigid mounting necessary for a machining operation whether it be grinding, milling, or turning on a lathe. The labor involved may end up costing more than a replacement. Then there is the issue of the condition of the springs.
Availability of replacement parts could be the determining factor. If you have a scarce one that cannot easily be replaced, it would make sense to recondition. If it is one that is commonly available, it might not make economic sense to resurface one/
 
I've done many in years past.

It is much easier if you have a pressure plate vise to assist in disassembly/reassembly but I've not seen one in decades.

Depends on the clutch. You need to have enough material to work with. Used to be common on truck clutches, but has pretty much gone to throw away parts.
 
Lots of outfits sell rebuild clutches and do so on a exchange basis and charge an extra core fee which they pay back when you send the core .
Not anymore with automotive clutches though.
