Case 750L Dozer – Parts, Specs

Description:

Serial Number Location:

For Case 750L Dozers (manufactured from approximately 2005 to 2011), the serial number plate is located on the left side of the frame, just behind the blade lift cylinder or near the articulation pivot. Always verify the serial number before ordering parts, as Tier 2 and Tier 3 engine configurations were both used in this model range.

Common Issues & Fixes

Hydrostatic Lag or Hesitation: Often due to dirty charge filters or low pressure—replace filters and recalibrate the controller if needed.

Blade Drift: Usually caused by worn tilt cylinder seals or internal valve spool wear—rebuild the cylinder or replace valve assembly.

Overheating Under Load: Check radiator and hydraulic cooler for clogging; ensure fan drive system is fully functional.

Loss of Travel Power: May be due to weak swash plate response or worn track motors—perform hydraulic testing to confirm.

Fuel Priming Issues: Air leaks at the hand primer or clogged lines—replace primary filters and inspect all clamps and fittings.

Electrical Faults (Tier 3 models): Look for loose ground wires or corroded harness connectors, especially near the fuse panel and ECM.
