    Yanmar Engine Dealers on West Coast?

    I have a customer with possible engine problems on a Yanmar powered stationary genset. I just talked to my Isuzu guy who told me how Yanmar fired all their dealers and has no network now. This engine is a 3TN88 I believe. I'm going to diagnose it later. I would like to know if there are any...

    The State of Technical Training in 2023

    I have a hired man who has shown some interest in learning more of the theory behind the work we do at a generator shop. I logged on to the local community college today looking for the old courses I took "way back in the 90s" Engine machining specifically. I learned a lot about engines by...

    Ear Protection Headphones

    The older I get the less tolerant of things that may damage me somehow I recently noticed how much quieter it was working with borrowed headphones as well as ear plugs on. Less stressful also. Trouble is it is hot here much of the year. Minor consideration though. Any recommendations for...

    John Deere Part Number Prefixes

    Just wondering if there is anything to be learned from JD part numbers. More common parts like filters, gaskets, sometimes alternators start with RE or sometimes R. A fuel injection pump reman started with SE. Part of a HPCR pump started with DZ. Any rhyme or reason to this?

    Junkyard/White Marker Worth a Hoot?

    I have been looking for a marker that is worth anything to write on black surfaces, etc. in legible white (or other light color). 2 types I have been fighting found at the parts house: 1. Has a small metal tip that pushes in a tiny bit and paint comes out. If writing on a vertical surface the...

    Exhaust Pipe Wide Band Clamp Question - How Would You Fix This?

    Got a little exciting today - load testing a genset with aftermarket DPF, which was plugged, and blew apart this joint ahead of the DPF. On further inspection it was done very sloppy, nothing lines up, can't get the 2 pieces to go close enough together, originally only 1" clamped in either end...

    Deere 4024 Lots of Fuel in Oil

    I have a 4024 powered genset in the shop for a simple checkup. I have seen this unit before, no trouble noted at the time. That was a couple years ago. 456 hours total. 4024HF285 PE4024L139816. It has sat for years. When I went to change the oil, first I noted the dipstick was high...

    Deere 4024 Code 627.18 Low Voltage

    Finally got a low cost (already had the controller) solution to pull codes from a Deere 4024 I am working on. I got a code SPN 627 FMI 18 that does not have a good reference on an internet search, but it seems to be related to low voltage of something. Either the injection controller or else...

    Chinese Equipment Scan Tools

    I just discovered that these things exist on Amazon and Ebay. Looks too good to be true but the price is right, might want to try them. Just wondering if anybody has any suggestions or experience. I work on Deere, Cummins, Isuzu, Kubota, and Caterpillar stuff, in that order. All what they...

    It Begins: Big Bud Tractor to be Produced Again, Simple and Repairable

    I have said in other threads, the time is ripe for a Marmon truck or someone to come along and build things like they used to be. I am not into ag, but this just came out

    Ford LRG425 Ignition Modules Discontinued - Ford 4 Cyl Pinto Industrial Engine

    I'm working on a Kohler genset with an LRG425 (Onan equivalent would be a 20ES or GGDB?) that has the ford DIS. Apparently they discontinued the original ignition controller, and offered a kit to upgrade to an updated one, which has also been totally discontinued/NLA. The last PN we have is...

    Window Wash Fluid and Freezing

    What do you guys who live where it's cold think about window was fluid? Here in sunny Ca they sell water-only stuff below a certain elevation but we can get methanol containing fluid above x number of thousand feet. Trouble is, it still doesn't work well if the window is cold-just freezes back...

    Simpler Trans Temp Gauge

    I am wondering if anyone makes a simpler trans temp gauge for my 2006 GM 3500 with 4L80. I don't need or want a big full size dial with 270° sweep cluttering up the dash or hitting my knee. It just needs to be something very small that I can refer to if necessary. Also rather not physically...

    John Deere 4045 HPCR Low Engine Power

    Deere 4045HF285 serial PE4045L034496 This is a common rail engine but no other fancy features. Generator engine, 1800 RPM only. It can maintain 1800 RPM right up to about 70 kw electrical which would equate to 94 HP, neglecting losses, engine cooling fan, etc. If load is increased beyond...

    Mitsubishi S3L2 Droopy Governor

    I have a genset with an S3L2 engine on it. Used with a bunch of hours. Nominal RPM is 1800, fixed by the throttle lever being held by the min/max bolts so that it cannot be moved. With no load, it will run about 1950 RPM and at full load, it goes down to 1725 or lower. Increasing the fixed...

    Diesel Suction Leak Troubleshooting

    I have a customer unit, brand new under warranty, that is failing to start after it sits a week or so. We suspect possibly a suction leak. I am thinking of taking the ends off the suction line and pressurizing with a slight bit of air and looking for diesel leaks and/or soap bubble checking...

    Air Intake Parts, Rubber Elbows and Aluminum Pipes

    Where is a good source for various sizes and angles of the clamped rubber elbows and straight pipe sections like commonly used under the hood of a class 8 truck? I have a couple of custom air intake hoses that are NLA but could be reworked with the right parts. Somewhat smaller than a 14 liter...

    Simple Gear Box Oil Recommendation

    A couple of simple gears in an iron housing. 2400 RPM 1800 RPM out. Manufacturer is not much help. They specify 80W 90 with .05 gal "enhancer". I don't think we are going to get much more from their support clowns. Enhancer makes me think limited slip modifier, but why would that be needed...

    John Deere 4024 Oil Pan Leak and High Oil Level

    Working on a 4024 that has an apparent leak around the oil pan. It might also be making oil. The customer states that it takes 3 gallons on an oil change and the pan is very shallow but skirt very deep on this engine. Is the oil pan gasket submerged in normal operation? Are these engines...
