Case 750 Dozer – Parts, Specs

Description:

Serial Number Location:

For Case 750 Dozers (including 750, 750B, 750C, and 750M variants), the serial number plate is typically located on the left side of the machine, just behind the front blade arm mount or on the firewall inside the engine compartment. Always confirm the serial number when ordering parts, as there are key differences between older 750 series (pre-1988), 750B/C (late '80s–early 2000s), and Tier 4 750M models.

Performance & Design Highlights

Durable Powertrain: Mechanical fuel-injection engine paired with a 3-speed or 4-speed powershift transmission for steady pulling power in grading or clearing.

Operator Visibility: Sloped hood and open cab design (early models) or enclosed cab with ergonomic joystick controls (750M) for improved line-of-sight and reduced fatigue.

Hydraulic Responsiveness: Dual-cylinder blade control system delivers smooth lift and tilt for precision dozing.

Adjustable Track Tensioning: Easy-access grease fittings allow field adjustments to minimize track wear and de-tracking.

Blade Configurations: Straight blade (S-blade), angle blade, and 6-way PAT blade options across different generations.

Routine Maintenance

• Engine Oil & Filter: Replace every 250 hours

• Transmission Oil & Filter: Change every 500 hours

• Final Drives: Check oil level every 100 hours; replace every 1,000 hours

• Hydraulic System: Inspect fluid every 250 hours; change every 1,000 hours

• Fuel Filters: Replace every 250 hours

• Air Filters: Inspect weekly; replace when restricted

• Track Tension: Check daily; adjust as needed

Common Issues & Fixes

Blade Drift or Weak Lift: Often due to worn hydraulic cylinder seals—rebuild kits are available and easily installed.

Transmission Slippage: Typically caused by worn clutch packs or low fluid—inspect fluid levels and pressure test the transmission.

Track De-tracking or Misalignment: Check for worn rollers, idlers, or loose track tension; replace worn hardware and grease adjusters.

Excessive Engine Smoke: May indicate injector wear or clogged air filters—clean or replace components and check fuel quality.

Electrical Shortages (Older Models): Inspect under-dash wiring for corrosion or rodent damage; rewire with sealed connectors if needed.

Brake Fade or Creep on Slopes: Adjust band brakes (on mechanical versions) or inspect hydraulic brakes (750M) for leaks or wear.
