As far as the hydraulic issues go, I have no movement on the left travel motor. Gauges just arrived. I have to figure out how to hook them up, where, and what to test

Takeuchi TL130 Drive Issue

You had trouble when lap bar harness was connected. I believe arm float is next to horn button. The buttons on left joystick are for auxiliary hydraulics, and the left trigger switch is for 2 speed.

Yes, thx. I found the operation manual. I just tested hydraulic pressure on P1 and got 0 psi in forward and just under 1000 in reverse with no track movement at at in either direction. Any thoughts?
Sorry. I'm not a hydraulic expert. But I believe there's separate pump for each drive. They both test same? How's the fluid look? Change the pilot filter under cab?
What's the story with this machine? You buy it as a non runner?

Yes, i bought it and knew it had a drive issue. But i was hoping it was a guild and filter issue be cause of a lack of maintenance. The left drive would barely move. Now, left wont move at all. Its up on blocks, so i can run the tracks and engine while working on testing pressures. But I’m not really sure what I’m looking for. What is correct and what is not. I do believe you are correct, there seems to be a pump for each side.
Everything else seemed to work hydraulically.
Wiring was a mess with a bunch of components broken or missing, like solenoids, switches and jumper wires everywhere.
ALL fluids and filter have been changed now. All wiring has been replaced. At this point, I got to much invested to stop now, plus its become a personal challenge. Who is our resident hydraulic expert?

Yes, I have the service manual but my readings are 0 on P2 but the track is turning same thing on P1 but that track wont turn. Going to check the charge pressure now.

I’m getting strange readings. P1 0psi forward and 900 in reverse, P2 0 psi forward and 500 psi in reverse. Charge pressure 0 psi. Pilot test port (P3) gives 0 psi readings also. WTH? Am I doing something wrong here? All hydraulics seem to be working except for the left travel motor which i cant get any movement out of.

What is the pressure on port "C"?

0 psi. Which is the test port on the sub valve block.

"C" is from one of the gear pumps on the front of the hydrostat pumps. If "C" is zero, then the travel will not pressure up. If zero, either the gear pump is shot, or it's output is going dtraight through the hydrostat pumps...to tank.

How would I determine which one it is? And could that effect just one travel motor?

I'd like to see that pressure from port "C" before jumping to any conclusions.
On my TL150 machines, I've never had to replace that gear pump. But, then again, I've never had travel issues. Some are @ over 10k hours.

I’ll get a video of it but don’t think I can upload it to this thread

You can, but you would have to upload it to YouTube first.

I’ll work on that

OK, somewhat of a correction. Changed gauge and got charge pressure of 240 at idle and 260 at high idle. Then pressure dropped to about 110 when joystick is moved
