    Hitachi 220-5 hydraulics bogging engine down

    Did you ever figure out what the issue was with this machine? Trying to diagnose a Komatsu PC220LC-3 that practically stalls the moment I introduce any hydraulic pressure. Trying to first find out if the issue is engine vs. hydraulics.

    Excavator bogging down

    How much fuel pressure should I see at that point? I assume pressure (PSI) will be a good measure of fuel volume as well, correct?

    Excavator bogging down

    I noticed that someone has put an aftermarket electric fuel pump on this machine, thus bypassing the original priming fuel pump. It looks like a little diaphragm pump with no pressure regulator. Could this pump be going south and not providing enough fuel volume for the engine to operate under...

    Excavator bogging down

    Did you ever figure out what this was? Working on a friends PC220LC-3 exhibiting similar problems. Been sitting for a few months, got it started then it died. I think it ran out of fuel so put more fuel in, bled the injectors and it's running and sounding normal. But the moment I hit any...

    How to Bleed Fuel for Komatsu PC220-3?

    I'm trying to get a Komatsu PC220-3 running again. Ran out of fuel yesterday and I've since added more and was looking for steps to get it started again. My friend who owns the machine says just leave the key on for 5-10 minutes to bleed the injectors. The machine is off site so I wanted to ask...

    1st Time Dozer Buyer - Looking at 76 Case 1150B - Need Advice

    I'm looking to buy a dozer for limited home use and found a 76 Case 1150B in my price range. Seller says it has a hydraulic line leak on the blade for the tilt (metal line vs. hose) and one injector line is leaking at the fitting. Other than, that he said the undercarriage is good. Sounds like a...

    Komatsu PC-130K5 Losses Power After Cold Start

    I just went to do a little more digging before the ground totally freezes up and my Komatsu PC-130K5 started fine but after about 5 minutes started to loose power. My guess it is was starving for fuel. It's been below freezing the past couple of days here in New Hampshire and I am guessing the...

    Location and Process to Change Hydraulic Filter for Komatsu PC-130-K5

    This may be an obvious question but I have learned better to ask first. Where is the hydraulic filter located on a PC 130-5 excavator and what is the best procedure to replace, if there is one? I see a filter on the back side of the tank, in the right engine compartment but wanted to know if...

    Komatsu PC130 Does Now Swing Left or Right

    Hi John. We took a photo of what I think are the solenoids. If these looks correct, how can I tell which is the right one? (trying to track down a shop manual in the mean time)

    Komatsu PC130 Does Now Swing Left or Right

    Hi John. Determined today the machine is a PC130-5. Serial # K20716. We found the toggles under glove box. Changing them back and forth didn't seem to do anything. The display is sun faded but you can read it with a little spit. No errors shown. Where can I find the swing solenoid? Seems testing...

    Komatsu PC130 Does Now Swing Left or Right

    Any chance you know where I could find the serial tag on this PC-130? I guess the PC-130 is a European, 'gray market' version of the PC-120. Talked to its owner and he reminded me that the display is so sunfaded you can't read it. Also reminded me that there has been several other 'jumpers' made...

    Komatsu PC130 Does Now Swing Left or Right

    Hi John. Thanks for the detailed reply. How can I tell the Dash series? The machine is about 15 mins. from my house so I can run over and check a few things and report back if that helps. I'm pretty mechanically inclined but never worked on heavy equipment. The deal is the machine can come 'live...
