Hello Thank you for this video. I have a Takeuchi TB153FR that is having similar issues where one track by itself won’t have power but when I apply both they function with the right track not providing near as much power as the left. Could you make a video explaining how the relief valves operate and how it’s malfunctioning can result in uneven distribution of power to the final drive?

Hi. Nice vid sir. Just wondering if a bad main relief check valve seat would have the same effect to other function like, swing perhaps? Thanks! ❤️

it could affect all functions (both bad), or all functions on one side of the control valve (one bad check valve), but not one individual function like swing.

A couple of days ago i changed the seals of the drive valves(found under the paddles) of a CAT 219DLC. Today i moved it but when i came to move it again it didnt want to move neither way. The paddles responded because i heard the Hydraulic pump. Could there be air in the Hydraulic system?

Hello, My cat 311c right track seized, most oil leaked out from centre joint and retainer plate at bottom of centre joint/ swivel joint got bent like a bowl with both holding bolts snapped off, was told the hydraulic main pump needs changing, put new one in and the same thing happened. New seals and new retainer plate destroyed. Now I am told the travel motor needs changing? Could you please help in what could be destroying the retainer plate with so much pressure? these ar one track drives put in just 50 hrs before running time?? Any advice would be most appreciated. Jason

I've got a similar problem with my EX60-2. I have full power when both levers are used either the same or in full opposite directions to spin. If I relax on one of the levers the machine doesn't have the will to turn. If I slowly ease into it with only one lever often the motor will hardly load down and the track will just sit there and barely move/shudder. If I move the lever fast I have power. My machine has a flow combiner valve. Could this be the culprit? I took both of the relief valves out last night and disassembled them and they both look just fine.
