Jacking/blocking/turning worked! Unfortunately, I was focused on getting it all lined up while doing three things at once. The HST unit is on... but I didn't notice one of the O-rings had slipped off. Moments after celebrating success I saw it laying on the catch pan I had under the tractor...

I tore down my BX2200 tractor down some time ago for a leak (appearing to come out of the top of the HST, which was actually an issue with O-rings). I finally am getting around to reinstalling the unit. I cannot seem to get the motor shaft (lower shaft) splines to line up and engage. At...

The verdict is in and it is not one I hoped for. I pulled the shift cover, not too bad to do, but I did have to loosen the floor board up so it could tilt high enough to come out. The Parking Brake "gear" had a couple of teeth break off. One of them fell in exactly the wrong place and landed...

Thanks for the suggestion. Unfortunately, yes and no loose nuts or bits anywhere to be found. I have the tractor up and jack stands and it is definitely coming from the transmission/differential area. If I block one wheel and rotate the other by hand I can hear the clicking and feel it bind...

I tried plugging the unused filter port. This moved the leak to the top of the gasket between the two parts of the HST. It appears either the gasket has failed or the casing has warped. Either way I have to pull the HST to check it out. The next question is, if the gasket failed why? Is...

While rolling hay, after stopping the tractor for a break and coming back it started to make a loud click when moving. The click is proportional to the speed. Upon inspecting the tractor the "netural" spring for the parking brake had gone missing. Replacing the neutral spring did not resolve...

Thanks, I stand corrected. Not the news I wanted to hear. Guess it is time to pull it a part and take a closer look. I sure was trying to avoid that. Richard

I am fairly certain there is an opening that is there by design. Now it may should have a freeze plug or threaded plug in it, but the opening is definitely in the casting and not a crack. It is the top of the front HST housing, not the back section with the relief valves in it. I have circled...

On the BX2200 HST, does the oil return through the point marked in blue in the attached image? And is the point marked in red an open vent at the top of the HST? If not where does the fluid return from? The charge relief valve (items 15/16 in the attached image) appears to flow the excess...

Found the problem and it is resolved! Having a parts diagram to look at saved the day. The Position Control by the seat moves a linkage that moves a shaft that moves a linkage arm. This arm has a tab that will push the actual position control lever that goes in to the hydraulics housing. The...

No air in the cylinders or lines. If I disconnect the Position Feedback linkage I can lower the arms all the way to the ground, but they won't raise back unless I push the linkage forward. Disconnecting the draft feedback linkage and moving it does not affect anything. Called the dealer they...

Since this appears more likely to be a service/repair issue than an operator issue I have created a new thread in the "Service, Repair and Maintenance" forum to continue seeking advice. http://www.orangetractortalks.com/forums/showthread.php?p=77893#post77893 Thanks for all the input so far. Rich

I had a thread in Tractor Operating, however now it seems more likely it is a service/repair issue rather than operator error. 2009 M8540, No cab, lift assist cylinders. No attachments on the 3pt. The position control has virtually no effect (it will raise the arms ever so slightly when...

Lift cylinders are in the holes closest to the tractor. A quick visual inspection of the linkage doesn't show anything obvious. It was however dark and I was using a flashlight. I will double check tomorrow in the daylight. Regardless of the position control setting the arms only move when I...

In the past the lift arms went almost down to the ground. It has been about 2 months since I used the 3pt hitch. I'm not sure what 'lift assist' is. It does have the "High Capacity" (large) lift cylinders on it. It also has the extra low (creep) speed for 3 ranges of 4 speeds each. Aside...

With the outer (position) lever is all the way forward I get the same results. With the inner (draft) lever all the way back the arms drop from all the way to the top to about 24" off the ground when the lever is about 1/4 way forward. Moving the draft lever further forward the engine/pump...

I recently acquired a 2009 M8540 (no cab). I went out to hook up a bush hog today and could not get the 3pt arms to go below about 24" off the ground (they will raise up to 36"). The control levers closest to the seat adjust the height, all the way to the back of the tractor drops the arms to...
