Trouble pumping moly grease.

[Ronster]

This is a follow up to my Grease for Excavator thread. I switched to Lucas Construction and Mining grease with 5% moly (available in my area). It seems that a few fittings do not want to take much of it, other fittings overflow out the pin bushings like the old grease I was using before. Is moly grease harder to get into pins and bushings with tight tolerances? Not an old machine, just now coming up on 50 hrs. Just wondering. Next will be greasing the swing bearing teeth, and then the swing ball bearing at 250 hours. Anyone have similar issues with moly grease?

Nope. Just those issues with bad or old zerks.

You might want to consult your owners manual as far as moly grease and ball/rolller/needle bearings are concerned.

That being said it is a pain in the ass keeping up with two different types of greases and I really don’t think my employees keep them separate at all but I try to keep the moly grease out of bearings. Moly really excells on pins and busings.

Kubota manual does not mention moly grease. Just some Shell or Mobil EP2 stuff. I'm always overthinking this stuff........

I wouldn’t say that. Research moly grease a little and make your own informed decision on bearings and moly.
