🔧 Maintenance

Oil Change Interval Engine:

Typically every 40-60 operating hours or annually for gasoline engines, potentially longer for diesel, depending on operating conditions and oil type. Manual will specify exact intervals and oil grades.

Engine Oil Type:

Refer to manual for specific viscosity (e.g., SAE 30, 10W-30 depending on temperature and engine type). For diesel, specific diesel engine oil grades are required.

Hydraulic Fluid Type:

Allis-Chalmers specified its own hydraulic fluid (e.g., ACCO Hydraulic Fluid), but modern equivalents like John Deere Hy-Gard or universal tractor transmission fluids (UTTF) are often compatible, check manual for specifics.

Transmission Fluid Type:

Typically requires specific gear oil or tractor transmission fluid. Manual will detail grade and capacity.

Common Wear Points:

Worn clutch components, hydraulic pump or cylinder leaks, carburetor issues, ignition system wear (points, condenser), front axle wear, PTO shaft wear.

📚 Vehicle History

Manufacturer History:

Allis-Chalmers was a prominent American manufacturer of agricultural machinery, industrial equipment, and electrical products, known for its innovative orange tractors.

Key Models Evolution:

The B series was an entry-level tractor, evolving through models like the C, CA (with electric starter and lights), WC (row-crop), WD (with adjustable front axle and higher stance), and the powerful WD45 which represented a significant step up in horsepower and features.
