    Hoof governor rebuild parts

    Does anyone have a parts breakdown for the belt driven governor? I changed the belt on my 632 yesterday and spun the governor pulley and it didn't appear to have any resistance. Should I feel something or should it rotate freely? It's too wet around the house to try and put a load on the machine...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    Good news! My Clark 632 is up and running! The shuttle valve was stuck in the drive motor. Tore it down and put it back together. I now have drive on both sides and it will spin in a circle on blacktop! I few more minor things to work on , but at least it moves. It rained here in Pennsylvania...

    Ross drive motors

    That's good to hear. I will clean and reassemble. Can you explain the operation of the shuttle valve?

    Ross drive motors

    I just pulled my drive motor from my 632 because I have weak drive on one side. I disassembled the motor and everything looks good. The shuttle valve was stuck and wouldn't move. Would this be the cause of my very weak drive? Can the shaft seals cause the motor to have weak drive? They are very...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    I was able to swap the hoses on the pumps and verify both pumps are good and the wheel motor is bad. Looks like removing a drive motor on this thing will be quite the job. I tried removing the caliper plate last night and decided I need to loosen all the bolts for the pump and lift it up in...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    Thanks. I'll look into it this week. I keep reading about timing the drive motors when you assemble them. Is there a good written procedure for timing the motors? I have the service manual, but I can't see the reference to timing anywhere. I know the previous owner had drive motor issues and I'm...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    Pulled the pumps and determined I put the assembly together wrong. Put it back together and now the right side is driving with real power and the left side is weak. Getting ready to pull the left drive motor. Do I need to remove the chains to pull the drive motor? Thanks, Lance

    Oil pressure low or water temperature high.

    Bobcat 630 Charge Pressure at Pressure Switch Port

    The hoses were switched at the pumps so each pump fed both motors. Now the right side is acting normal . The front pump lever has a noticeable vibration to it when the swash plate is moved. I'm not sure if one of the pistons is stuck, but the pump is coming apart again this weekend. The left...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    Just finished reviewing before and after photos and it looks like I reversed the 2 drive motor hoses on the right hand side of the pump. After work, I'll swap them and report back.

    Bobcat 630 Charge Pressure at Pressure Switch Port

    I don't think I mixed them up. I ran it last night and it is doing the exact same thing as before I did the pump. Low charge pressure and very little drive to the wheels. I think I am going to cap the charge pressure hose going to the hydrostatic pump. If the charge pressure increases to by-pass...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    Well, I had the pump wrong. Changed the direction on the ring. I now have bucket hydraulics but still very little charge pressure. I have been cycling the bucket functions a few times and shutting down the engine to let it rest overnight and again during today while I'm at work. Still no drive...

    Bobcat 630 Charge Pressure at Pressure Switch Port

    I pulled the hoses off the motors and drained what fluid I could. I think my vane pump is wrong. I have some conflicting diagrams of the correct orientation. My parts manual shows the arrow on the pump( on the left side of the machine) pointing down. Tazza's photo shows the arrow pointing up. I...
