My Cat 215 has suddenly stopped steering. The machine runs, but I can't turn it left or right. Has anyone had this issue before? What should I check first?

My John Deere 770A motor grader has a blade that keeps drifting down. I rebuilt the lift cylinder and found a bad spool valve. After swapping the valve to the other side, the drifting moved too, so I'm sure the spool valve is the problem. Does anyone know where I can find a replacement spool...

My **Komatsu PC150LC-6K excavator** only clicks when I turn the key on-no monitor or machine power. I replaced the battery solenoid, but the issue remains. Using a jumper wire powers it up, but the engine won't shut off until I remove the jumper. Has anyone had this issue or know what could be...

My 1992 Case 1845C has an intermittent starting problem. It often just clicks when I turn the key, even after replacing the starter, battery, ignition switch, cables, and wiring. It may start fine a few times, then the problem returns. Has anyone found the cause of this issue?

My 1972 Case 450 dozer starts running hot while pushing dirt. The temperature climbs to around 220F and begins pushing coolant out, even after replacing the radiator cap. The thermostat has been removed, and the radiator is clean. I also noticed the fan pushes air through the radiator toward the...

I recently came across a Euclid TDT 14 scraper with a Rolls-Royce C6 engine. I'm wondering if this engine was factory original or if it was swapped at some point. Does anyone know if the Rolls-Royce C6 was offered in these machines from new? Any information would be appreciated.

I'm trying to find the bucket pin dimensions for a 2003 John Deere 120C. I need the pin diameter, ear-to-ear width, and center-to-center pin spacing. From what I've found, Deere 490 buckets may fit, and the pin diameter appears to be 65 mm with a 255 mm ear-to-ear width. I'm just missing the...

Precision agriculture technology seems to be advancing fast every year. What precision ag equipment do you think is worth watching right now, and which innovations are making the biggest impact in the field? Are there any specific brands or systems that have genuinely improved productivity or...

I'm having an issue with a Moxy MT36 dump truck where the transmission keeps filling up with hydraulic fluid. When the fluid level gets too high, the truck won't shift. If we drain the excess fluid, it shifts normally again. I'm trying to figure out where the hydraulic fluid could be crossing...

Looking for advice on doing a CAT 963 track adjuster reseal on an older machine. One side has started leaking and I'm trying to figure out how big of a job this really is before tearing into it.
