New BX22 owner maintenance question: 2 zerks on BH fail to take grease ?

[LuckyPierre]

I know they work as I removed the offending pair and proofed for blockage by squeezing grease threw them, they were fine. Then reinstalled the pair and again both refused to take any grease. I squeezed my grease gun so hard, that moly shot between then GG head and the hydraulic grease hose !

The tractor appears well maintained and greased properly. BTW: I shut the tractor down and unloaded all the FEL and BH hydraulics

It sounds like the bottom of the zerk is bottoming out. Try slightly loosening one, and shoot some grease and see what you yield.

One of the offending zerks is on the BH stabilizer piston attach point, same same on the other one the BH stabilizer arm piston. From what I could see it would be impossible for a zerk to bottom out ?

It still is worth a shot to back it out a little. I had to do that on a brand new loader and zerk. Other options include:
There is a grease zerk unclogging tool that shoots lighter oil through it.
I seen some on YouTube apply heat to the area which can get grease flowing and uncaked.
Replace the grease zerk.
Change the position of the joint and see if it will then take grease.
Disassemble and clean out the area you are trying to grease.

I had a zerk on a trailer jack that wouldn't take grease even when new. I just left it because it was new. Then a couple years later I bought something called a Loc-n-lube grease gun nozzle. I clamped it on and horsed the grease handle a little bit and in the went. Pricey at 30 bucks but well worth it IMHO. Leaves no mess either.

Try repositioning the cylinder to put load on the pin from different directions. sometimes that gets it to take grease.

I also have a BX22. The zerk is in the end of the pin, so unless they forgot to drill the hole, it's not bottomed out. I would take the zerk out, find a drill bit that will fit the hole and clean it out. Should go to the mid point of the pin. Then spray it full of penetrating oil and screw the zerk back in. Try the grease gun again and see if it will take.

Both good ideas and one or the other will work. I reposition weights and loads and get grease through that way. Only had to spray oil in once.

Thanks all. Stopped by the Kubota parts store and bought 2 oem zerks. On the BH arm zerk that the hydraulic piston is mounted to the new zerk refused to take grease ! Unscrewed it, stuck a thin screwdriver through the opening and pulled out fresh grease. Reinstalled it and was able to get some grease in but realized it's something to do with piston mount as the old grease is not being pushed outer. Was able to get some grease in the stabilizer arm but again old grease is not being pushed out. Tomorrow, I'll uncouple both pistons and cleanup the solidified grease.
