Case 921E Wheel Loader – Parts, Specs

Description:

Serial Number Location:

For Case 921E Wheel Loaders (produced from the mid-2000s through early 2010s), the serial number plate is typically found on the left side of the front frame near the articulation joint, just behind the front left tire. Always confirm the serial number before ordering replacement parts—particularly important due to mid-series updates in emissions systems and control electronics.

Common Issues & Fixes

Hydraulic Lift Lag: Often caused by contaminated fluid or worn valve spool—flush system and replace return filters.

Transmission Shift Delay: Typically due to solenoid failure or electronic shift control faults—inspect wiring harness and test solenoids.

Emissions Fault Codes (Tier 3): Check EGR valve function and clean turbocharger vanes—replace sensors if codes persist.

Overheating in Heavy Applications: Clean debris from radiator and hydraulic cooler stack—ensure fan clutch is operating properly.

Joystick Drift or Control Lag: Inspect pilot pressure supply and linkage—replace joystick assembly or recalibrate controls.

Brake Warning Light: Commonly linked to low brake fluid or internal accumulator leak—inspect brake lines and seals.
