COMP Turbo Oil-Less Service Question

MoulaZ · 03-02-2019, 07:03 PM

Stiffened up a bit after re-greasing but not as stiff as it was brand new. Had a minor heart attack when the nozzle wouldn't come off the zerk fitting after the 5 pumps. Ended up figuring out you need to loosen the head and that it's designed this way to lock onto the zerk fitting while pumping.

You was getting a hydraulic lock on the zerk fitting. The bearing cavity is full of grease and the pressure was holding the nozzle on the zerk. You are at full capacity in the bearing. Next time, only do 4 pumps. Too much grease is not good for the bearing either.

I don't think so. After figuring it out, I was able to re-produce that 'lock' without additional pumping. Similar to those screw drivers with multi-bits that have a locking nut that when tightening locks the bit in place through compression, it's the same thing here. It's an odd design but it works fine.

When I was working. I would run into this hydraulic locking of the fitting all the time on equipment.

The grease fitting on the grease is adjustable to fit tighter or looser ....if you set it too tight it is difficult to get back off ...I don’t know if all of them are like this or not
