Kobelco hydraulic excavators

blankey85 · Apr 13, 2015

I'm having trouble diagnosing an issue with a 2004 Case CX-14. I'm not sure who is the actual manufacturer being as the service manual also applies to a Kobelco SK13SR.

It has Kawasaki pilot valve body and a 3-cylinder Yanmar engine. I've posted looking for help with a hydraulic issue but haven't gotten any responses. So is this machine actually a Case or Kobelco?

Why does my sk170-8 lose power and speed when it runs for a few hours. I mean a drastic reduction

I have a MDI Yutani MD180 and am needing the part numbers for the hydraulic filters. There are two. One big one in the main tank and one in the return for the hydraulics.

Hi all.

I have chance of buying this digger in the pictures, think it is a SK50-05736. But a bit vague at the moment. Not entirely sure on year of manufacture but I have the serial number so guess this can be worked out.

It is fire damaged, engine wiring loom is burnt out, the engine will run and with a bit of messing around I am told the hydraulics will work, but obviously needs a fair bit of fixing.

Is it worth a go, are they any good? No experience of Kobelco, have a Komatsu though. Are parts, possibly a loom easy to come by, is there anything I need to be weary of?

It doesn’t look to bad, been parked up for at least two years, so a bit green, doesn’t look to burnt and charred.

TIA.

Sk150

Hello, I am looking at buying a 98 SK150 LC -4, for farm use. I believe it may need some new track chains. I am thinking they will cost around 3,000 for a pair. Am i about rite? Do you believe that this is a good series of machine. It will have a Cummings engine. Thanks for your insight. Mudober

Hello all, I bought a 06 sk350lc at auction and it had been running fine. We brought it up from DFW and it ran for the first month perfectly. Then the turbo went and we had it replaced. Now the machine is blowing a lot of smoke, like it is unburnt fuel and may be too rich. I have talked to Kobelco and they said they have seen the problem before. Last week the mechanics were at Hino school and will be back Monday. They are going to send someone up to update the computer. Anyone have experience in this?

Thanks,CD

Thanks,CD

CD, could it be that the turbo failure may have plugged the aftercooler? I don't know anything about your machine, but it seems plausible that if it did not smoke before and suddenly began after changing the turbo that there is an air restriction somewhere (assuming the correct replacement turbo was installed). If the old turbo scattered then you would have residual pieces in the charge air cooler, and if it lost seals it may be plugged with oil.

Kobelco SK135SR vs Kobelco SK135SR-LC, is the LC with the longer tracks likely to be a better machine for working on slopes or is the standard SR tracks with less weight and less track length to power likely to have better climbing ability?

Just spent the day on an sk500. Phenomenal hoe, incredibly fast, smooth and powerful. Very impressed.

Hi guys,

Our Kobelco SK210-6 has developed a weird problem or we just didn't notice is before we bought it. Bascially when you move the arm in, towards halfway of the stroke when the arm is just outside of being vertical to the ground, the arm just falls about 6-10inches and bounces a bit and stope moving inwards. So its kinda like 10 inches before vertical its almost like the pressure on the return line drops or something and the arm just falls down and then the pressure seems to catch up after 2-3 seconds and it continues to move in. Pretty weird.

Would be grateful if someone can point us in the right direction.

Thanks

Hi, First time on the forum. I have a Kobelco SKO45 just using it on the farm, digging trenches, removing stumps, moving dirt and general lifting. Can someone tell me the capacity of the hydraulic system? I have a light on the control panel that I think is "low oil", I have topped up with 15L but still on? Thanks in advance for any assistance.
