motor's been running hot on our harvester rig, wondering if there's a max temp i should be keeping an eye on before things go sideways

Question by: Brett H on Mar 8, 2026, 7:32 PM

Keep your operating temperature at or below 180 degrees F. Past that threshold you risk seal degradation and accelerated wear on internal components. Fluid viscosity matters here too, 70 SUS at operating temperature is the target range, so if your fluid is thinning out more than that under load, that's likely contributing to the heat issue.
