Loader 300 CX Grease Zerks Plugged, maybe?

[Deere Dude]

On a 2010 JD 300CX loader, there is a 1" solid round between the arms near the bucket. It has zerks on both ends that I really had to put a lot of pressure on the gun for them to work. They almost seemed plugged, I greased them maybe 30 hours ago and they seemed much better. Does that seem normal. The rest of the zerks allow grease a lot easier than these. Am I worried about nothing?

Kubota calls for greasing loader every 10 hours of loader operation I don't know about JD. I am guessing that your grease channels may be plugged with old grease and dirt particles. Keep greasing until grease pops out around the joints. Grease much more often.

Any time a grease zerk will not take grease it could be a problem. I would start by putting the bucket in a different postion. Maybe raise the bucket or put down pressure on it and see if that makes a difference. It could be it's just where the bucket is that it is preventing grease from flowing. Taking the weight or bind off the pivot point might help.

Pin is most likely drilled to center of pivot point then cross drilled.

Try this first...if it doesn't help, the zerks may be clogged with some old dried up grease. Pull the zerks out and take a look. Even if you can't clean 'em up, they're pretty cheap.

Good advice by all above, combining the ideas should cover your needs. I have had to change out some of the zerks over time and as Roy mentions these are cheap. Moving the loader changing positions will work sometimes. Greasing more frequently is very good advice, I do this every 10 hours on the clock.

If you can't get a zerk to take grease then get to the root of the problem and find out why and fix it. Waiting and putting off will only cost you more down the road.

JD also recommends lubing every 10 hours of FEL time. Easy yest important maintenance.

Often it's just the little ball that's stuck. When I encounter a zerk that won't accept grease, the first thing I do is use a pick to free up the little ball. In my experience, nine times outa ten the fitting accepts grease after that.

Thanks for the advice. It just seemed strange that the pressure needed was about the same on both sides. Maybe I'll drop the bucket or something and try it again and see what happens.

Warming the zerk with a heat gun "gently" then greasing also helps. Softened grease flows even when it's old.

Roy is spot on...I had the exact same trouble a couple of weeks ago, pulled it out and it was full of sludge. Once cleaned and reinstalled, worked like a champ.
