Rear front axle support grease zerk

   / Rear front axle support grease zerk #11  
coolbrze - - I hit all 36 zerks on my tractor, grapple & rear blade twice a year - spring & fall. Four strokes per zerk with a pump gun. Followed with shop rags to wipe up the old stuff that which has squeezed out.

The front axle support on my L4060 has a breather plug that is removed first, then the zirk is greased until it flows out the breather hole.

The front zerk does on my MX5800 also but I was asking about the rear zerk (no breather plug). The manual states to remove the breather plug & grease the front zerk but doesn't say anything about the rear one...

yes you're right. my MX500 had a breather plug on ft. pivot. nothing in rear as i recall. is the rear zerk delivering? if so, just look for grease outflow around flange. if not, remove & replace zerk best regards

Uhmm. I didn’t know my L4060 even had a zirk to the rear, sure enough I checked and it’s there (and no breather). I’ll try lifting the front end and give it its first greasing in 250 hours :(

On my little L2550 the rear pivot support did not come with a zerk fitting. I had to replace the bushing due to wear and I drilled and tapped the piece for a zerk so it could be greased in the future. I always "unload" all the joints if possible when I grease the tractor so I get grease into the areas with pressure on them.

A couple of years ago I asked a service guy at a large Kubota dealer about the breather plug, wondering how they get them out without chewing them up. He said something like, "We don't remove those, and I don't think anyone really does, just be careful not to over grease." I wonder how many people have never removed their plug?

just remove the plug & pump till it exits from the breather opening, etc. not a big deal, that's why it's there, (within that model's design) it allows the flow. otherwise, the grease never gets to where it's needed.

Yes, that is the purpose of the breather plug -- my point is that this one is hard to remove the first time and it appears that some people may never remove it.
