Front axle center pivot o ring replacement?

[broketractor]

I put grease in the front axle center pivot support of my l2501 4x4 without taking the vent plug out. Heard a pop & grease shot out the back of the housing. Has anyone had to repair the o ring or seal. Any help would be greatly appreciated!!!

Just a single O-ring, no seals.
Easy, lift the front tires at least 2" off the ground
Then remove the six bolts holding the front and rear carrier.
Drop the axle down the 2" then remove the front carrier.
Inspect the carrier for cracks.
Replace O-ring and then reverse the process.

Thank you I will get it fixed & I won't forget to pull the vent plug from now on!!

There’s little reason (in most cases) to shoot tons of grease into most grease-fittings.… especially this one where not rollers or ball-bearings exist. Only a “little db ‘ll do ya’” ….(old Bryl-cream slogan).
Really… just ONE shot of grease in most plain bearings is appropriate.

It only take one shot to pop the O-ring out of this setup.

Another case of “size matters”. ( my ”shots” are tiny since the surgery)
…however, if Kubota says to “grease it”…and provides a zerk…. it needs grease.

My own front axle pivot is an early model…the rear pivot (shared with the 4wd shaft) has a zerk….… but the pivot fwd of the axle does not…yet has a need for grease apparently, as K put a zerk in later models. K wants RealMoney for the later, replacement-part….. so I’m considering drilling/tapping/inserting a zerk… and don’t look forward to the task. According to Messick’s “hints”…it takes 3 hours to jack the tractor, support the axle w/straps, remove the 4wd shaft coupling, then unbolt the bracket, reverse the procedure.

If you drill it you must drill 2 holes one for a zerk, one for a plug.
