checking travel motor case drain on an excavator. troubleshooting weak travel

where did you find that flow meter? thats nice.

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?

[@seanfoley4849]

I have a similar issue but low power / speed overall

[@alankwong7182]

@@seanfoley4849 Either of you guys figure this out? I've got the same issue on my TB260.

[@seanfoley4849]

@@alankwong7182 I bought a shop manual for my machine along with a set of gauges off of vevor, found that my pressures were good, and the shop manual mentioned I could adjust something called a “pc valve” and turn the set screw 90degrees to increase power. Buy that shop manual

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! ❤️

[@hydraulics]

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.

[@rosellersumonod5975]

@@hydraulics these check valves have system pressure rating or low pressure?

[@mphepg]

@@rosellersumonod5975 they are exposed to full system pressure

Thank you for this video. Could it cause low pump pressure?

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?

[@randymccullough4038]

So what relief valves seats did you replace? My komatsu has been doing the same exact thing for years.

[@randymccullough4038]

Can you drill down what pop its springs and seats you replaced? I have this same problem on my komatsu. Thanks

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

[@shawnpatrick5452]

Did you figure out what was wrong with the machine? I have cat 315bl that did the same thing. Any info would help. TY in advance

[@dusting4188]

I have the same machine new undercarriage new tracking motors. When you track the left is 50% of the tracking makes it walk towards the left side till you reset it any ideas? I’m thinking stuck check valve maybe

[@hydraulics]

Reset it?

[@Agirhydro23]

With this machine how you check for error codes speed sensor/ prv solonide ?

[@hydraulics]

You don't. There's nothing electronic about this machine (aside from the climate control system in the cab)

[@Agirhydro23]

Does the pump de stroke manually then?

[@Agirhydro23]

No shift solonide working off speed sensor conected to controller then.The cat 311uc is controlled this way not saying they are the same machine but are c models my machine is giving me problems shift solonide not functioning properly

[@hydraulics]

@@Agirhydro23 yeah this 307C is called a "C" series but doesn't have all the electronics of the bigger excavators

Helo!my pc 128 komatsu had a problem on the panel board,i can not go on hi travel.even if you push the botton on hi in the panel board it would not go to high speed.thank u

[@MatthewWilson83]

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.

[@shortrelaxingrainvideos8619]

That's problem with the adapter sieves on the valve block

[@MatthewWilson83]

@@shortrelaxingrainvideos8619 adapter sieve? I checked the case drain on my center joint yesterday and it is flowing when the track is stalled so I think that's my problem. Case drain on the track motor is almost nothing when stalled.

[@nabiladi4913]

U can check return pressure also if above 6 bar ( 88 psi) u need to change the pump or motor hydraulic

[@hydraulics]

Hmm. Who's to say the cooler or filter aren't plugged up? I wouldn't trust your test.
