In my area most T650's are hand control with foot throttle. Only way to go in my opinion. In the future foot controls will go away.

Looking to upgrade from my Gehl 4625sx to a new or slightly used machine. Needs/wants: 1. Cab with heat/ac 2. Track loader as I'm going to be going in hilly pastures 3. Hi-Flow, just in case I need in future 4. Speed for roading from place to place and also when snow blading roads The Bobcat...

Gehl 4625 tilt cylinders do not hold position very well. The cylinders leaked, so I replaced both cylinders and replaced seals on lift cylinders. The tilt cylinders still do not hold position. Assuming it's a leak within the Main Control Valve? If so can that be fixed by replacing seals on Main...

First let me say that every time I post I have to click the preview button and then go back to edit mode in order to get into the text box to type my response. Are any of you other guys running into this? Good point on changing the filter soon I’ve done it once I should have cut it open but I’ve...

Put it all back together tonight, new pump, new oil (just in case old oil overheated), new hydraulic oil filter. Runs great now. I'm realy happy I found the problem before it ruined something. in hindsight I may have not needed a new gear pump. However, I took old gear pump apart and brass...

Tonight I took the suction hose off and the orange plastic hose was stuck approximately 5" down the suction hose! Mind you the orange hose had to go through a 90 degree elbow. And...it was doubled in two. After seeing that I have no doubt as to whether it should have been there. It should not...

Inside tank

Here's a picture, taken of the inside of the tank. There's a little reflection from the camera flash. I question whether that hose should be there???? https://mail.google.com/mail/u/0/?ui=2&ik=83acbc56cf&view=att&th=163ecdfe171c4808&attid=0.1&disp=safe&zw

Drained hydraulic tank oil in order to service/clean the hydraulic oil strainer which is located inside the hydraulic oil tank. The strainer is suppose to thread onto the elbow leading the the hydraulic fluid supply line. The strainer was not screwed in place and was actually laying in the...

Inside shot of Gehl 4625 hydraulic oil tank with strainer remove.

Thanks Tazza I found them. Starts at left motor goes to the front hydraulic unit then to the right motor and then back to the tank. They are daisy-chained in that fashion. Do you suppose I could unhook the beginning beginning furthest from the tank, take the cap off of my tank and blow air...

How do I tell which hoses are the case drain hoses? Does just the hydrostatic pump have case drain or do hydraulic motors also have case drain - I wouldn't think so?? Since it's a tandem pump does each pump have a separate case drain hose or just a single hose off one of the pumps? Where does it...

Actually, I believe it is a lip type seal. Has a spring inside it to grip the shaft. I'm going to check the bearing and measure the shaft around the bearing; maybe there's too much play there causing the leak. Another guy also said to check the case drain hose; said if the case drain hose is for...

After further inspection the shaft has slight visual wear, but I'm a hobby machinist and could detect no measurable difference in diameter within a couple 10 thousand's using a micrometer. However you can feel a very, very slight wear on the shaft. Questions: Would anyone recommend turning the...

Update: Just disassembled the Eaton 70344 piston pump, the forward pump of my Gehl 4625. The trunnion seal was leaking oil. I had recently replaced the trunnion seal, but it still leaked. So I decided to take the pump apart, hoping there was a worn o-ring on the trunnion shaft inside the pump...
