    Komatsu PC200-7 Hydraulic Problem

    On my PC 200, the operator says at times the arm won’t lower unless he first lifts the arm a little first. Then today the engine switched off while working. When trying to start the engine it cranks very slowly (like when the batteries are low) and we noticed while cranking the engine, the arm...

    CATastrophic 320C failure

    So today the swing motor on my Cat 320 disintegrated. Looking at the photo, any theories as to what could have caused this? I suspect a failure in the slew box which caused the slew box internals to push upwards and broke the swing motor housing.

    Is there a quick fix?

    Thank you all for the replies. The idler is 100%, pic taken while fitting the track after replacing the final drive. I suspect the seized up track contributed to the failure of the final drive. The problem first occured at 1800 to 2000 hours, but to date the machine clocked 2800 hours with the...

    Cat 320 d2 or sumitomo sh 210-5

    Cat is good, but don't under estimate Sumitomo. Excellent value for money machines. I bought a new Sumitomo back in 2000 and sold it after 22000 hours. Did the under carriage twice, replaced seals in all the cylinders once and resealed the pumps on 18000hrs. Replaced a few hydraulic hoses, other...

    Is there a quick fix?

    Thanks for the reply, uffex. I'm trying to get the supplier to assist by stripping and cleaning the link assemblies, but so far no luck. I'll tighten the screws some more on the supplier, hopefully they will come to the party.

    Is there a quick fix?

    I replaced link assemblies (same brand) on both my Komatsu PC200-7 and Hitachi ZX200 two years ago. Both sets of tracks developed the same problem. It looks like seizure on the pin/bush.The machines did about 1800 to 2000 hrs when the problem occured. The supplier says: 'Sorry, our warranty is...

    I sold the machine as is, made the buyer aware of it and gave him a discount. He said he will get it sorted out.

    CAT 320C Left track slow

    So, I eventually found the problem and the machine is functioning 100%. The machine is fitted with a manual throttle since the oringinal throttle control failed. With the throttle dail turn up to max, the machine is 100%. If the dail is in the idle position, with the engine at full throttle...

    CAT 320C Left track slow

    Thanks for the reply walkerv. Serial number: CAT320CJANB03733 I had a problem with the hydraulics killing the motor, I've replaced all hydraulic filters and it seems to be functioning better now. The main problem now is the slow track. I don't think it's caused by any of the possibilities you...

    CAT 320C Left track slow

    I need advise please, been battling with my machine for the last month, but it's still not right. The left side track is much slower and very weak compared to the right side track. In "back-up" mode it travels and turns perfect or in "Auto" mode with the PRV unplugged. Does this point to...

    CAT 320c Hydraulics stalling engine

    Thanks Mark, so connecting the plug on the throttle unit, should clear that up, the throttle unit is currently unplugged as we're running the machine with a hand throttle.

    CAT 320c Hydraulics stalling engine

    Dapperdan16, thanks for the reply. To answer your question:I don't know, I bought the machine as a non-runner, it stood vandalized for about 8 or 9 months before I bought it. It had mostly cosmetic damage and missing one track, so I refurbished it and fitted a timber grapple, it worked for 3...

    CAT 320c Hydraulics stalling engine

    My CAT 320c (CAT0320CJANB03733) stalls the engine when curling the bucket in and out, also on boom up it stalls when the boom reach full up position and I don't let go of the joystick immediately (even on full throttle). It travels perfectly, no problems. I have replaced all fuel lines...

    Hitachi Zaxis 200-1 fast travel only

    I need some advise please. My Zaxis 200-1 (13000 hours) fast travel only and it's really struggling to rotate the under carriage. First I had an electrician check the electrics out and it's all good according to him, but it is possible he missed something. So next I overhauled the centre...
