Just curious if anyone else has crossed this bridge. I've had this grinder since new.....2006-ish. The last couple of deer grindings last year and before....I noticed a few drops of what looks like oil left on the table top when I move it. Has anyone else had their LEM do this? If so....what was your fix? Thanks.....

Part - Grease Seal for Big Bite Grinders | LEM Productshttps://www.lemproducts.com › product › 1777-big-bit... Grease Seal for our entire line of Big Bite Grinders. This Grease Seal is located in the grinder motor and is used to prevent grease leakage. If you see grease in the hub of the grinder, this seal may need to be replaced.

Mine is the 3/4 HP and I've had it now since 2013 or 2014. I've put around 20 animals through it and mine is going strong with no issues.

Thanks Paul....this one doesn't leak out the front, it's underneath and the oil is clear.

I would call the service dept for recommendation.

That is what I was going to do. I was wondering if someone here has seen that before and what their fix was. I'm guessing something is oil filled and there is a oring or seal leak. LEM doesn't show that for this model (Model 535).

It's likely that there is a gearbox that is filled with food grade grease. That grease breaks down over time and will begin to leak oil when in use. I had a similar issue with my wife's Kitchen-Aid Mixer.

Mine is leaking also. I emailed them twice with no reply.

A follow up.....

I took it apart to troubleshoot the leak. It is coming from a cork gasket that goes between the face plate and the front of the motor. The "oil" is the grease starting to breakdown. The LEM tech rep in the Parts Dept said the grease starts to breakdown at the 10-12 yr mark and will leak. In this case...the cork gasket leaked. The repair kit costs $21 including shipping. It includes a new cork gasket, new grease and a new oring that goes around the driveshaft. The tech rep said the outside possibility is the big capacitor split and was leaking. That has vegetable oil inside. Mine was still good. Here's a couple of pics. I have a pointer pointing at that cork gasket behind the face plate.

A follow up. Just finished changing out the grease, gasket and oring. Very easy to do. Here's a few pics of it after I took the cover plate off. You can see the little oring on the drive shaft. You can also see the liquid grease that broke down. I cleaned all of that out, cleaned the mating surfaces, wiped with alcohol, laid down a thin coat of Permatex #2, on both mating surfaces, put on the new cork gasket and put it back together....works as advertised.
