T200 can’t reverse hydraulic flow

[smiley.keith]

I recently purchased a Bobcat T200. When I connect to the accessory hydraulics I can't change the direction of flow. I understand the right control handle switch (left - right ) toggle is supposed to reverse the flow but I can only get it spinning in one direction. Any suggestion where to start troubleshooting? Thanks!

On what attachment? Have you tried more than one, like a grapple or something without a motor?

Not all attachments will spin both directions, particularly high flow attachments.

Yes I connected it to a Weed Badger that has a hydraulic motor. It spins both directions on my other Bobcat but only one direction on the T200. I understand a switch on the right control handle is supposed to reverse direction but It only spins one way. I am unfamiliar with the T200 and don't know where to start troubleshooting. Thanks for any help.

Just asking simple questions since we can't see the machines.

How many hydraulic connectors are on the T200? Is it a high flow machine?

Since it doesn't have a case drain I assume it's not high flow. I called Bobcat with the serial number and they said the flow was 21 gpm. I can only get the flow to go one way. The owners manual says a left-right switch on the right control handle should change the flow direction but that isn't working. I need to identify if it's a wiring problem, a bad solenoid or other issue. Thanks for your help

My 864 (same machine as the t200) has the same issue. My next diagnostic step will be to swap the harness dongles on the two sides of the valve control block where they connect to the two solenoids that control the aux spool. I figure if the working flow moves to the other flow direction the error is in the switch or pcm controller whereas if the working flow is in the same direction the error is in the solenoid or spool. I'm going to watch this thread very closely.

This would be my next step too.

Ok, lift up your cab and locate the Hydraulic AUX solenoids, they should be the only solenoids with the exact same connector on top of the Control Valve, you could swap the connectors or the whole solenoid. Problem by swapping the whole solenoid could be that the stem is sticking or damage and then it still will not tell you the issue.
So its either the solenoid/stem assembly or your RH handle assembly

Thanks cowboy my other Bobcat is a 542b and it's not as complicated as the T200
