Features Of The Allis Chalmers WD

Let’s Learn in-depth about the very sturdy and efficient features of the Allis Chalmers WD which still makes them a reliable tractor even after 70 years since its production.

Engine

The Allis Chalmers WD tractor engine is a legendary power plant that has powered countless agricultural operations around the world. This gasoline engine has a displacement of 3.3 liters, with a four-cylinder, naturally aspirated configuration that delivers exceptional performance and durability. With a cylinder bore of 102.0 mm and a piston stroke of 102.0 mm, this engine provides ample power to handle the toughest farming tasks. The compression ratio rating varies depending on the version, with an early model rating of 4.5:1 and a later variant rating of 5.75:1. The engine produces an impressive PTO output power of 26.4 PS(19.4 kW or 26.0 HP).

This engine’s design and specifications make it ideal for a wide range of farming applications, providing reliable and efficient performance that maximizes productivity while minimizing downtime. Whether you’re tilling fields, hauling loads, or performing other farming tasks, the Allis Chalmers WD tractor engine is a powerful and reliable choice that delivers outstanding performance and longevity.

Transmission

The Allis Chalmers WD tractor features a non-synchronized gear transmission system that provides exceptional power and durability for demanding agricultural operations. The transmission has four forward gears and one reverse gear, allowing the operator to choose the appropriate gear for the task at hand. Unlike synchronized gear transmissions, the non-synchronized gear transmission system requires the operator to match the engine speed to the desired gear speed when shifting, which can be challenging but also provides more control over the powertrain.

This transmission system provides a maximum forward speed of 15.7 kmh (9.8 mph) and a maximum reverse speed of 3.6 kmh (2.2 mph), allowing the operator to move quickly in forward gear and precisely in reverse. The non-synchronized gear transmission system is known for its strength and durability, making it an ideal choice for heavy-duty agricultural tasks where reliability is crucial.

Hydraulic System

The hydraulic system of the Allis Chalmers WD tractor features an open-center design that provides reliable and efficient performance for a variety of agricultural tasks. The hydraulic system has a capacity of 4.7 liters (4.97 US quarts, 4.14 Imp. quarts) and can operate at a pressure of up to 1200 psi (82.7 bar).

The hydraulic system features one valve, allowing the operator to control the flow of hydraulic fluid to the equipment being operated. This valve provides precise control over the hydraulic system, allowing the operator to adjust the speed and force of the equipment being operated. The open-center design of the hydraulic system ensures that the hydraulic fluid is always flowing, even when the equipment is not in use, reducing the risk of overheating and providing consistent performance throughout the workday.

Other General Features

The Allis Chalmers WD tractor is a remarkable machine that boasts an impressive set of mechanical features. Its manual worm and horizontal sector steering provide excellent control and precision, making it easy for the operator to maneuver the tractor in any direction. The manual external compression band type brakes provide reliable stopping power, even in the most challenging conditions. The open operator station allows for maximum visibility and comfort during long hours of operation, while the 56.8-liter fuel tank ensures that the tractor can keep working for extended periods without the need for frequent refueling.
