Case 850L Dozer – Parts, Specs

Description:

Serial Number Location:

For Case 850L Dozers (manufactured from 2009 to 2014), the serial number plate is typically located on the left-hand frame, behind the blade lift cylinder or beneath the cab step. Always confirm the serial number before ordering parts, as the 850L introduced updated electronics, emissions systems, and cab features not present on previous 850K models.

Common Issues & Fixes

Hydrostatic Surge or Hesitation: Caused by dirty charge filters or low oil—replace filters and top off with correct fluid.

Blade Drift or Inconsistent Lift: Worn or leaking cylinder seals—rebuild lift or tilt cylinders with proper seal kits.

Electronic Fault Codes in Display: Commonly due to loose connectors or moisture near the CAN bus—reseat and dry connections.

Cooling System Warnings: Dirty radiator or worn fan clutch—clean cooling stack and inspect for cracked hoses or belt slippage.

Track Slippage or Misalignment: Worn sprockets or incorrect tension—adjust track tension and inspect idlers.

Slow Travel Speed in One Direction: Can result from swash plate calibration issues or charge pressure drop—run diagnostic and recalibrate electronically.
