Case 750K Dozer – Parts, Specs

Description:

Serial Number Location:

For Case 750K Dozers (manufactured from approximately 2001 to 2015), the serial number plate is typically mounted on the left side of the frame, near the articulation joint or behind the left lift cylinder. Always verify the serial number before ordering parts, as early and late 750K units may vary in emissions equipment and electronic control systems.

• Track Adjustment: Grease daily and check tension on both sides

Common Issues & Fixes

Hydrostatic Response Delay: Typically caused by dirty charge filters or control calibration errors—replace filters and perform ECU reset.

Blade Tilt Drifting: Often a result of internal cylinder seal wear—reseal tilt cylinders with OEM kits.

Low Hydraulic Pressure Alarm: Inspect main relief valve and verify hydraulic fluid viscosity during colder starts.

Fuel Delivery Problems: Air leaks at fuel primer bulb or clogged primary filters—replace hoses and filters regularly.

Electronic Fault Codes (Late Models): Check for corroded ECM connectors and run diagnostics through onboard display or diagnostic port.

Track Tension Loss: Usually linked to leaking grease adjusters—replace seals and inspect recoil springs.
