Fault Phenomenon: XCMG XKT mining truck weak travel, transmission fluid has a burnt smell.

Troubleshooting Process:
– Checked friction discs: discs blackened and thinned.
– Checked steel plates: plates discolored and deformed.
– Checked oil pressure: low clutch oil pressure.
– Checked operation: prolonged partial clutch engagement.

Root Cause: The transmission control valve failed, causing low clutch oil pressure and prolonged clutch slippage, generating high heat that burned the friction discs.

Required Parts: Replace transmission clutch friction discs and steel plates, repair control valve.
