    Hydraulic Issue(s)

    Update... I replaced the cab blade control body. It solved the important part of the problem. The blade lifts and still leaks down but much slower. But more importantly it has down pressure and it holds 100%. I drained the hydraulic tank and changed the filter element and that also greatly...

    Hydraulic Issue(s)

    Sorry. I'm not spending every spare moment I have on the machine. As I posted earlier, it behaved much better the other day. At this point I'm waiting for the replacement blade control valve body to arrive before anything else happens. Its a sandbox toy, just pecking away at fixing it up.

    Hydraulic Pressure Issues

    Thank you fella for your responses. I left out a lot of other maintenance I've done.... I had the blade cylinder tested, its fine, the only other thing is the cab control which is a steel valve in an aluminum body. Replacement is $292... should make the blade usable and give back hydraulic power...

    Komatsu Serial Number

    In the auction (Edmonton) it stated "EPA LABEL IS PRESENT" which I've since learned is mandatory for any machine to enter the US. I'm not certain that removes it from the grey category. I will be doing a complete service once it arrives and will likely visit my local dealer (1.5 hrs away) and...

    Komatsu Serial Number

    I was going to bid on lot # 813 ( 304.5 Cat) so I'm logged in and watching. Lot 809 (the one I bought) stopped at 22,500. I quickly thought about it and hit bid. 15 secs later... 'sold' for 25,000. 1767 hrs. The only 'downside' is the steel tracks but I'm told I could switch to rubber. I'm super...

    Komatsu Serial Number

    Hi all. I just purchased a PC55MR-2 through Ritchie Bros. On the listing they listed it as a 2006. I won the auction and after going through all the pics they posted, I looked closely at the VIN plate they posted. Clearly legible it is stamped Manufacture Year 2015. The serial number they posted...
