    Another chapter in the rebuid of this machine. Replace all fuilds and fiters and put in a new drive motor. Unit moves good with good speed and power but the lift arm is very slow and weak. Cant even lift a half bucket of dirt.

    Have you inspected the gear pump for damage internal?

    Do you know where the float valve is located? And how would I check that?

    A few years ago we had a TL130 and TL140. If a remember correctly the float function is electrically controlled by servos.
    First question: Does the bucket have good curl or breakout force? You mentioned the lift arms are weak, but are the bucket cylinders strong?
    Second Question: are you running the correct hydraulic fluid? our old TL130 and TL140 and our new TL8 use 15w-40 diesel engine oil.
    Our old TL140 would occasionally drop out of high speed because the solenoid was weak. If the float valve were to fail, I would think it would default to closed versus open...

    “Controlled by solenoids” sorry for the typo.

    I do not know. Do you have a service manual? Someone should be able to give you one on here if you ask.

    the relay is behind the kick panel by operator feet.
    The loader control valve is by operator right shoulder.
    I know the 2 speed solenoid is by operator left leg. I think the float is also there.

    Either way, try the relay first. Check for power there. You should be able to activate the relays with the cab up; safety systems must also be activated. (Lap bar and seat pressure sensor if equipped.)

    Yes I do. But I thought I’d ask to shorten down the search .

    I’ll get back to you later today about that. It definitely seems like the bucket works faster but I’ll check on break out
