    Visited some old equipment

    Imagine how hot and noisy that d7 would be to operate. Wonder if the engine has to run at high idle or low idle to get correct generator rpm. Guessing by the power points there is power as well of the welders.

    4 way pattern Changer on my hitachi

    After learning to operate an excavator as a 7 year old on a JSW pattern machine i still find SAE and ISO patterns backwards. That must be one complex valve inside.

    Radiator leak

    It looks like the schematic you posted is of the hydraulic and trans cooler circuits which contain oil rather then coolant. As stated above fliuds tend to drip down and blow in direction of air movement from fan. So i would be looking forward and up of where the coolant is accumulating.

    D5B Final Drive Leak, I think.

    A flush out with diesel wont do it any harm. Oil is cheap. I would get it hot and change it again.

    D6 9U Fuel Issues

    Do you remember what colour the smoke was? I think that will give us a big hint into what direction to head to. I believe the pony motors are great design. Frees everything up, builds oil and fuel pressure and puts heat into engine. They can also mask underlying issues with lack of compression...

    Caterpillar D4H low power smoking black

    Did you ever get around to checking torque converter housing oil volume?If the scavenger pump is blocked or the converter has excessive leakage the housing fills up with oil and it acts like a hydraulic retarder.

    Caterpillar D4H low power smoking black

    By the way she is over fuelling, i dont think you have a low pressure fuel issue. Does it look like the injector pump has been off before? Paint missing from bolts, adjustment screws and un painted components normally gives it away. The reason i ask is that i think its got a diesel knock or...

    Komatsu D57S-1 Head gasket seep

    When you first posted about the head gasket and was selling it, i was going to suggest chemiweld or liquid head gasket sealer, pull the head bolts down half a turn and send it to the auction. Bit late now

    Cat 120G Serial Number lookup, Blade questions

    Hough 930

    How do you pronounce Hough. My old man had one in the late 80’s and we always called it a “hough”. But most pronounce it “huff”. I think it was a word play on huff and puff. But interested what others think. Ours was a rear axle steer with a cabin. Was also addicted to areostart. Old man liked...

    Champion 710a steering issue

    Continuous spinning of the orbitrol when hot sounds like steering cylinders to me. Easy way to check steering cylinder is hold it on the lock (if you can) and feel if the cylinders get hot. Or crack the opposite hyd line.

    D5 no crank no start

    I would start with basics and approach it as multiple issues. Number one starter motor. Jump poles on starter motor to establish if wiring and isolator is ok. then work out why it wont crank. Then why it cut out. And maybe stop throwing parts at it.

    M313D C4.4 engine; crank but won't start

    Had a few perkapillers with no start issues. Have seen crank and cam position sensor failure, ecm earth issues from the braided earth strap and excessive injector leak off from u/s injectors. Also ecm driver failures and electric lift pump failures and chafed/shorted wiring looms. I still think...

    Iveco stralis, start, stalled, won't start again

    Do you have a photo of the warning lights or codes on dash? If it was in neutral when shut off it should start with out air in tanks so may have other issues. Disconnecting batterys can do wonders sometimes.
