Customer has a Sani-serv model 404 soft-serve machine. They have been going through a face plate every 6 months or so - cracking in the middle where the plastic center rod that sits in the dasher assembly rests.

They are not over-tightening the knobs, not running any parts through the dishwasher...

The dasher runs free and smooth. The rear bearing is good (fairly new). Seals and o-rings are all good and lubed. Product is good and normal consistancy.

I'm kind of at a loss... is anybody else running into this?
