Gehl 4625SX HELP!!!

[hosickc]

I have a Gehl 4625sx skidsteer that will not move. I,ve checked out all the electric selanoid valves and they work. The electric brake has been bypassed. The bucket will tilt but the lift arms will not raise, it won't move forward or reverse with out killing the motor. I have the safety bar down so thats not the problem. I bought a manual and it hasn't helped. I tried to find the lockout valves to free the wheels for transport. The manual shows two valves but my serial number is higher than the serial number that the manual says has these. Any ideas would be greatly appreciated.

It is probably the drive coupler. Just for giggles have you tried a new seat switch and a safety bar switch may be the problem but then the bucket won’t tilt back at all either if that was the problem. Has to be one of the solenoids is going bad. Also this is probably not the problem but it could be a drive motor.

Also forgot to add get a service manual from you Gehl dealer with the right serial number that will cover yours.

It sounds like you have a later models 4625. This one had the manual drive pumps. You can tell by the floor boards. Early models had a basically flat floor board and your knees seemed to be up around your chin. Later models had a wings where your feet go. These wings had inch round holes with upsets in them.

On to your problem. To meet safety standards for the European market(and match what other manufacturers where doing) the machine must be immobile unless there is an operator in the seat and the restraint bar fully lowered. There are a total of 3 hydraulic soleniod valves. One for the lift, one for the tilt and one one for the spring applied, hydraulically released brakes. There are 3 switches that must close to make everything work. The seat switch, the restraint bar switch and the parking brake switch. I can't remember if the parking brake switch locks out the lift and tilt functions.

Get out a test light or a multimeter. Check all the switches to be sure they are working. Then make sure the soleniods are powering up. hold something like a small wrench near the black electromagnet. you should feel the wrench pulled to the electromagnet when it enegrizes.

You say you bypassed the soleniod on the drives. If there is no power to that valve then hydralic oil is diverted to the resevoir and no pressure is built to release the parking brake. The simplest fix is to restore the set up to the way it was wired by the factory. And the safest. Lots of people have been killed, on all makes of skid loaders, because they bypassed the safety switches.

If all else fails contact Gehl's service department in Madison SD. if I remember correctly the number is (605)256 6622.
