Rear front axle support grease zerk

coolbrze · Nov 3, 2018

Tried to grease the rear front axle support grease fitting on my MX5800 but grease was hard to go in & oozed back out. Does this mean it's full?

Unless you can see some type of damage to the zerk, it probably isn’t the zerk. It is probably the pressure behind the zerk. Lower your Front End Loader to slightly lift the front axle a tad. Or turn your wheel a bit to change the position of the guts behind the zerk.

If all that fails, you could change the zerk out, but I would focus on the easy things first.

King pins and front axle pivots are best lubed when pressure is off them, then the grease gets to where it really matters. Just use a jack or the loader to slightly lift while greasing.

There is no "full", at least on the Ls, not sure on the Ms. The back side of that pivot & grease zerk is open to the axle housing. So excess grease falls into the oil there. A bit doesn't hurt anything, but you dont want to go hog wild pumping grease in there.

I'd disagree that things are best greased under load. If it's under load the 2 primary wear surfaces are going to be pushed tight together. The non bearing side of the joint will have all the space due to OEM clearances or wear. So all the grease will go fill the void on the side that needs it the least. Probably splitting hairs a bit, but greasing under load isn't superior.

Edit: nevermind... saw the previous reply said off, not on. Apparently I dont actually disagree.

Here is a good video on greasing king pins:

The reason you jack it up is to allow the grease to get where the pressure is and that is were the wear will be. The same is for the front axle pivot because it has constant weight and not enough movement to work grease around.

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.

Thanks guys will jack her up then grease. How often & how many pumps for this zerk?

Grouse09 · Nov 4, 2018

My gut says “until release”. Or you may want to just go with 5 good ones and grease it more often.

I agree here
The little 1/8 pipe plug to be removed has a 7mm square head and is very tight.
Too tight for an open end wrench and no 7mm 4 or 8 point socket could be found at the time.
ViseGrips helped.,not ideal.
Good Luck!
