I need some advice on a Hobart L800 mixer. It is at a pizzeria that mixes heavy dough daily. The original complaint was that it leaked oil from below the main (planetary) shaft (not the agitator shaft). I ordered an oring and chimney and replaced those and that corrected the leak. However, when I pulled the main shaft I noticed that it was worn at the bottom bearing. The bearing looks good but it is very loose on the shaft. It can be pushed easily up and down on the shaft. There is a lip on the bottom of the shaft (see photo). Otherwise, the mixer is quite and runs ok.
My question is: replace the shaft and bearing? My cost on the shaft alone is $500+ from Hobart. I just don't want to have the customer pay for something he doesn't really need.
