3PH issues?

[MidgetMaestro]

Hi all -

About a year ago, our BX2200 3ph kept spontaneously lowering itself even when the control lever was up....after replacing tons of stuff, and ripping the whole tractor apart, we discovered that the culprit was a little teflon ring that had cracked/deteriorated around the main hydraulic ram. What a pain that was, taking the whole tractor apart for a $.90 o-ring!

Well to get at the ram, we had to remove the entire rear end including the notched hydraulic arms (that go directly into the hydraulics). My grandfather took these out, and put them back in, supposedly keeping track of the notch position. I don't think he put them back in correctly and here is why....

Our concrete pad is level so I used that as a base to take pictures:

The blade only raises about 5 1/2 inches off the ground, but can be manually (pulling the blade up by hand) raised by more than 13-15 inches.

I seem to recall the blade raising more than the 5 1/2 inches prior to the tear-down.

Can anyone confirm this?

Edit: I should add that the reason I am asking is there are several places on our property that the blade catches even when up because it is not high enough off the ground.

On my BX23, which has the same 3pt hitch as your 2200, when the lift arms are all the way up. From the center of the lift pin hole in the lift arm to the ground is 22 1/2". If your 3 pt. is all the way up it should come to a stop and you should not be able to lift it further by hand.

This may sound like a dumb question but------------- did you check the position of the center link, either in top hole or lower hole? Also how about the lift and lower stop adjustment? Just thinking here?

Both of you have helped immensely. I'm going to fiddle with the top link tomorrow. I don't think that the lift and lower adjustment has been messed with, but seeing as I have the mechanic's manuals, I can play with that a little bit.

Ah, a victim of the spline bandits!!!!!!


the lower link arms are designed to allow you to plow with a standard plow and drop near the ground so As much as i hate to say it its time to remove the lower link arms.

Now then, take a small pipe wrench and a wrap a rag thickly around one of the splines and push down on it with the pipe wrench until it stops with the valve open.

doing this allows the lower link arm to be near ground level where its supposed to be.

So as a result the other spline will be fully lowered at the same time.

The first lower link can be attached this way- take a tire crayon or warmed paint pen and place a dot on the spline at 12 oclock this is the fully lowered point that you are hunting for (if the top link is fully retracted your entire back blade will fall forward and drag on the ground once this is done and is what you want).

Then you can simply set the left lower link arm at a point one or two inches above the ground IF you do not use a mold board plow.

Do the same thing for the opposite lower link arm and then be sure to use a bubble level as the arms should be at zero degress grade and "Level" if the slab is level.

I guess I should add that when the arms are all the way down, it is 5" from the center of the lift pin holes to the ground.

That sounds about right. Your top link is way too long, thats all. Adjust it in 3-4" and you'll be all set.

On my BX2200, now owned by my son in law, when the lift arms are all the way down, they are really close to the ground unlike in the picture.

 

[Dead Horse]

guys, his problem is that the picture shows the lift all the way UP!



Yes, the lift arms are installed on the rockshaft incorrectly. There is WAY too much clearance between the lift cylinder rod end and the internal rock shaft fulcrum. This can be fixed by re installing the lift arms on the rock shaft splines in the proper position as I believe is explained in a post a few above......... (and yes, my specific terms may not be the ones used by the experts)

Even if the arm were put on wrong there are 2 things I see wrong. Are you sure you can even put them on wrong? Top link to long and on the blade the top link is up to high. From the lower link pins to the top link hookup should be around 14" and I think you well find you are at 16 or 17". The BX is not a true Cat. 1.
