    Hyundai R130 Electrical Problem

    So I again probed all the connections and lines and grounds i could find. Looked at the full schematic and troubleshooting options in the manual i have. Nothing was making sense. Took a step back and retraced my steps when it started working prior. Noticed that the step hand rail on the side...

    Hyundai R130 Electrical Problem

    Probed a bunch of connections and nothing was making sense. Everything had power. Pulled ignition switch, probed a bunch of connectuons on the switch, and wala, started working. Figured it was the switch. Put the cab back together, confirmed switch still worked. Figured it was a faulty...

    Hyundai R130 Electrical Problem

    So maybe a dumb question, but is this test on the wire harness that connects to the controller? Im assuming that you unplug the connector from the controller and test pin #7 on said connector. If thats the case, how is Pin #7 supposed to have power?

    Hyundai R130 Electrical Problem

    Got a R130 LC3 Farm machine that i finally got around to fixing up. Ive had coolant issues forever, so I broke down and replaced the head gasket. That turned into oil pan gasket and a couple other seals. Also pulled the fuel tank out and cleaned that out to remove a bunch of rust and other...

    Hydraulic Piston ID

    Sprung a leak in my hydraulic piston for my Geith thumb on my Hyundai R130 LC3. The only markings I could make out are shown. Looks like AH150125 and 05 May 00 1119? Trying to find a seal kit but those numbers dont pull up any information. Its a 5 inch cylinder, 2 inch bore.

    Head Gasket on Hyundai Cummins engine

    Head Gasket on Hyundai Cummins engine

    Komatsu pc300-lc-5 losing fuel prime

    Check all your hoses. I went through stalling issues on my Hyundai. Replaced the lift pump and that worked a little, then started replacing fuel line hoses. Each time it would help but would eventually stall. The hoses had very slight cracks at the fittings. They wouldnt leak so that you...

    JD 120 general rebuild thread, bushings, pins, CWS thumb wedge QC bushings, hoses

    Love the "talking to myself"! I need to do 2 similar projects on my R130 LC3, keep the pictures coming. My bucket needs attention, new wear plates, fix a hole in the bottom and new adapters/cutting edge. I also need new pins and bushings. Its a farm machine so i keep putting it off.
