⚙️ Engine Specifications

Make Model:

Allis-Chalmers Diesel (Specific engine model would be detailed in the manual, e.g., Allis-Chalmers 3-cylinder or 4-cylinder diesel).

Displacement Hp Torque:

Details for specific engine configuration (e.g., 3.7L or 4.2L) would be found in the manual, including horsepower and torque ratings. For context, the Model 190 typically featured engines in the 60-70 PTO HP range.

Fuel Type:

Diesel

Injection System:

Likely direct injection with rotary or inline injection pumps (e.g., Bosch, CAV). Manual would detail pump timing, testing, and overhaul.

Type:

Water-cooled

Oil Type Capacity:

Manual would specify SAE viscosity grade and API service classification for engine oil, along with oil capacity. Typically 10W-30 or 15W-40 for diesel.

🔧 Transmission

Type:

Likely a manual transmission with multiple forward and reverse gears. Could include a Multi-Power or shuttle-shift option.

Type:

Allis-Chalmers' 'Multi-Power' transmission, offering two ranges (e.g., power and field) with several gears in each, was a common feature, providing 12 forward and 4 reverse speeds. Manual would cover its operation and repair.

Clutch:

Dual-stage clutch for PTO and transmission engagement, or a single-stage clutch depending on specific configuration. Manual would detail clutch adjustment and replacement.

Transmission Oil:

Manual would specify the correct fluid type (e.g., API GL-4 gear oil of a specific viscosity) and capacity for the transmission and differential.

📐 Dimensions

Overall Length Width Height:

Specifications for overall dimensions would be in the manual. For reference, the Model 190 was a mid-size row-crop tractor, approximately 12-13 feet long, 6-7 feet wide, and 5-6 feet tall.

Operating Weight:

Manual would provide the tractor's operating weight, typically around 6,000 - 7,500 lbs, depending on configuration and tires.

Wheelbase:

Specific wheelbase dimensions would be listed in the manual, crucial for axle repair and alignment. Likely in the range of 80-90 inches.

🛡️ Safety Features

Roll Over Protection:

While factory ROPS may not have been standard on all 190s initially, the manual would cover the installation and servicing of optional or aftermarket ROPS if documented. Safety precautions for operation are paramount.
