Greetings to all from Hermosillo, Sonora Mexico. My first post in this forum. I need some help with a Kodelco SK210CL-9 excavator, Serial number: R0003573, Product identification number: YQ13-10215. The machine belongs to a client and it has some serious electrical problems due to having been submerged for some time. The owner purchased several wire harnesses and apparently his mechanic quit halfway through the harness installation. We need the complete electrical diagrams (or better yet...the complete shop/service manual) for the above mentioned Kobelco excavator so we can get it up and running. The manuals we've located online are for Asia and Oceania and are not correct. Any help with locating this information would be greatly appreciated. My email: mccloudexplorationdemexico@gmail.com

Hi

I only have them in hard copy but the parts manual is on line I will see if I can find a link for you.

You will find even with the serial number the correct parts are hard to get.

hello

I have a kobelco k 905 lc mark 2 1989, have someone tried using a electric 6-2 valve solenoid to split fluid on bucket cylinder to operate a tilt bucket, its an old machine and the cost is to high to buy aftermarket parts to the control valve block and all plumbing/parts that it needs. any experience?

Don't have a parts book too do you. Can't find one of them either.
My swivel joint is leaking. its a fountain of hydraulic oil. Seems damn hard to get at. Is there a shop manual as well? Must be a trick to it or pull the cab off. :(
Here you are.
Good luck.

I emailed you the manual.
Hi, I have an SK75UR-2 YR03796
I am looking for a shop manual that tells me where to hook up my pressure gauges and what my pressures should be.
It has started having issues killing the engine when pressure is applied against the bucket, (i.e trying to dig). I believe I am having relief valve issues, but would like to check it out. Thanks.
