Carlton stumper grease fitting

coolbrze · Oct 10, 2009

One of our grease fittings on the cutter wheel axle is locked up. I've e-mailed Carlton several times & haven't heard back but will call this coming week. I'm guessing it's the grease fitting itself that got debris jammed in it as we grease it every time we grind. My question is, the grease fitting isn't shaped like your standard auto grease fittings w/ a simple nut on the fitting. The "nut" only sticks out a hair & my wrenches won't grip this. Is there a special tool or any tricks to getting this sucker out? I guess I could weld something on it, but that seems a little extravagant to remove a grease zerk...

Pics? Maybe its pressed in instead of threaded. I've never tried this but they do have those little tools that you put on the fitting and hit with a hammer. Supposedly it forces a small amount of oil through the fitting, clearing it out.

I haven't had any problem getting them off mine. Maybe try a different wrench or even a pair of vise grips since you are going to replace them anyway.

My only problem with this is that there is probably some dirt or something jamming the zerk and if you pound it in there, doesn't that make it end up in the bearing?

I'd much rather just unscrew and replace the zerk. I have a whole container full of different sizes just for that.

Tell me about it! I just replaced the main cutter shaft bearing on my 7015. I spent $600 total. Bearings were $220 each, $100 to the machine shop to press old ones off and new ones on, and about $60 in new grade 8 bolts here and there.
