B-112 Hydro lift Test---Who'd'a Thought


MPH

Recommended Posts

As my lift quit working while blowing snow yesterday I started into it tonight. Wasn't so lucky to find a sheered key so I pulled the pump. Bench testing all seems well. Pushes 800 lbs each way, IF I change the gauge to each hose on the cyl.


Should have taken this pic with the rod extended, then it would show pressure.


This one I got glare on the gauge glass but it is just under 800psi.


So, guess it's off with the cab, tear the tractor half down and get the cyl out. All I can think is I blew the O rings out in it. Too look for such a simple problem


Had I not went out this morning with the preset mind of needing to pull the cyl I wouldn't of had to even remove the cab to fix the problem. Seems strange it would have unscrewed in 3-4 years since I put it on, hope the red locktite holds. Oh well, least while the cab is off I can check things out under the seat pan, adjust the Var. drive, then make up my mind if I want to put the cab back on.

Marty, If you cannot find the o-rings locally send me a pm. I bought big bags of each when I was re-building mine, I'll throw some in an envelope if you need them.

Had that happen to my 112 last spring. To be honest, I had forgotten about it until I saw your pictures. Mine buggared up the threads enough that I had to chase them with a tap and die to reinstall it. Glad it was something simple.

Hey Bob, surprized at myself for not seeing a lock nut even on the spare cyl I used in testing, which can be seen in the 1st pic, I looked at the Landlord, no lock nut there either so this morning I looked in my B-112 parts book and it does not show a lock nut either on the rocker arm end, only on the BGB box end. Am I missing something here?? Thanks

You're right. Used common sense, shouldn't have. Then the only way you can get it real tight is with the ram out and and tightened before ass'y. That seems silly.
