Snowblower rotation... Help

[ThomasXZ]

are you guys supposed to get snow this weekend I’m in the process of hooking up my snowblower hook. I adjusted the gear so it’s somewhat snug against the shoots. I don’t believe my cylinder that drives the gear is working properly I can spinet one way for 3/4 of turn and then I can’t spin it the other way and yes I am going all the way into the detent

Once I try to go the other way obviously it’s just stuck want to go one way or the other until I open a connection and release the pressure.

Everything else is working properly I research the issue and the issue before with people not going all the way to the right with the joystick which is not my issue.

The chute is mounted in a way that it has a lot of movement in it when turning. To accommodate this movement, you have to loosen the motor a little, just enough that it still matches the cogs in the chute, and it can't jam up at the end of the travel. I am assuming that your tractor snowblower has the same type of hydraulic motor as that is on your tractor's baby brother, the BX.

without seeing pix ,it's hard to 'see' what's not working but...
....mechanically disconnect the 'cylinder' from the 'gear', and manually rotate the chute by hand. It should easily move full range. If YOU can move the chute, that's not wher eht eproblem is..
Then, cycle the cylinder, the ram should go in/out full range. If not, maybe 'bad plumbing' ?

Correct. It is not jammed or anything I took the gear off as well to see if the issue would be resolved. Negative. Can rotate one way once I release a line to relieve pressure in the system. But once pressure in the system cant go left or right. It is stuck.

Correct it spins with manual hand power with the hoses disconnected. It will shoot the fluid out each way when I turn it. I can hook it back up. Have it spin one way then back other way slightly. Then locked up. Won't spin left or right.

I am away from home so I can't take photos till Sunday.

My assumption is that I have a bad cylinder pump ( not sure what it is called. That moved the gear. Not sure why the fluid won't release from one inlet when turning and to the other outlet.

I have the LX2980 snowblower for my LX2610 and found this in the Troubleshooting section-

I just installed my new BX5455hd snowblower and when I tried the hydraulic operated chute it was slow and stopped turning in one direction. I adjusted the “flow” on the 2 adjusters on the bottom of the motor…the adjustments were backed out a good deal…after turning the adjusters back in and tightening the lock nuts it operated much better and faster.

the only thing i did not do was remove item 6, and blow compressed air in. I did look in there with my trusty eyeball and did not see anything "plugging" the hole.

I do

I do not believe mine has thoses, I just have one like the photo above LX2980 snowmblower. Still away, probably wont be home till monday .

Have you tried swapping the 2 hydraulic hoses that are connected to the chute rotation at the quick disconnects to see if that makes any difference? it should just swap the rotation directions.

I have not yet. I figured. Because (fluid was shooting out of both of them) it wouldn't make a difference.

On that “picture” parts numbered “6” are the flow adjusters are they not? That’s what mine look like. Those are the flow restrictors…unscrew the locknut and screw in the Allen screw in the middle until the flow is adequate and the chute turns like it’s supposed to.

From my glance at them. They just looked like a fitting that screws in to the pump/ cylinder.

They are a fitting…flow restrictor fittings

Fixed:

Somehow material was in one of the flow restrictors... All good now

 

[DustyRusty]

Amazing the information that you can find in the manual. I guess that is why they supply one with every machine. LOL

So…did you increase the flow while you were fiddling with the flow restrictors?
What kind of “material” was in them???

I bought a shop service manual too. Just didn't arrive till today.

The flow stayed the same, as mine are not adjustable. Just some metal shavings. I am gonna take apart the pump or cylinder to see if there was somehow any real damage. [although with the flow.... if fluid is going in... not sure why it wouldnt move the shavings to the other side... and then cause that side to not move, but they both would get stuck. So not sure, I aint complaining it is working though. lol

I am having issues with chute rotation. The chute will only move when i pull the control lever towards me (left). If I switch the hoses top to bottom it will rotate back the other way. But again this is when i pull the lever toward me. When I push the lever away I can see the hoses loading up but the chute does not move. I also tried swapping the chute connectors with the up/down outlets on the manifold and the chute moved just fine. Also I hooked the up/down connectors to the chute connections on the manifold and it went up and down just fine. Any help with this issue would be appreciated.. The tractor is a Kubota B3000 and the hydraulic manifold has 4 ports, 2 top and 2 bottom. Like the dots on the #4 side of a die (From a set of dice). Thank you

The bucket spool on your loader valve is regenerative (fast dump). It works fine fpr hydraulic cylinders but cannot reverse a hydraulic motor. You need a separate valve for the motor.
