The Allis Chalmers WD45 tractor is a classic piece of agricultural machinery manufactured by Allis Chalmers in the mid-twentieth century. Founded in 1901, Allis Chalmers was a well-known manufacturer of farming equipment, construction machinery, and power generation equipment. The company was based in West Allis, Wisconsin, USA, and quickly became a leading player in the farming industry. The Allis Chalmers WD45 was one of their most popular models, and it helped revolutionize the farming industry with its innovative features.
One of the key features of the Allis Chalmers WD45 tractor was its powerful engine. It was available with either a 3.7 L four-cylinder gasoline engine or a 3.8 L six-cylinder diesel engine. The gasoline engine had a maximum power output of 33.1 hp, while the diesel engine had a maximum power output of 34.5 hp. Both engines were known for their reliability, fuel efficiency, and durability, making them ideal for long hours of use in the field.
Another important aspect of the Allis Chalmers WD45 tractor was its transmission. It was equipped with a sliding gear transmission with a wet disc clutch and 4 forward and 1 reverse gear. This transmission provided excellent control and maneuverability, making it easier for farmers to work with their fields. The wet disc clutch also helped reduce maintenance costs and increase the lifespan of the tractor.
Features Of Allis Chalmers WD45 Tractor
The Allis Chalmers WD45 tractor was a pioneering piece of agricultural machinery that helped shape the farming industry. Its powerful engine, reliable transmission, and range of other general features made it an ideal choice for farmers looking for a durable, efficient, and easy-to-use tractor. Lets learn more about its prominent features:
The Allis Chalmers WD45 tractor came with two engine options, a gasoline-powered four-cylinder engine and a diesel-powered six-cylinder engine. Let’s take a closer look at each of these engines and the benefits they provided to the tractor.
The gasoline engine in the Allis Chalmers WD45 is a 3.7 L four-cylinder naturally aspirated engine with a displacement of 3,704 cm2 (226.0 cu·in). It has a cylinder bore of 102.0 mm (4.02 in) and a piston stroke of 114.0 mm (4.49 in). The engine has a compression ratio of 6.45:1 for the gasoline version or 7.2:1 for the LP gas version.
The lower compression ratio and natural aspiration allowed for a more economical use of fuel. Additionally, gasoline engines were easier to maintain and repair compared to diesel engines, making them a popular choice for farmers with smaller operations or those who preferred a simpler engine.
On the other hand, the diesel engine in the Allis Chalmers WD45D is a 3.8 L six-cylinder natural aspirated engine with a displacement of 3,769 cm2 (230.0 cu·in). It has a cylinder bore of 87.0 mm (3.43 in) and a piston stroke of 105.0 mm (4.13 in). The engine has a much higher compression ratio of 15.5:1.
The diesel engine provided significant benefits in terms of power and torque. The higher compression ratio allowed for more efficient combustion, which produced more power and torque than the gasoline engine. This made the tractor better equipped for heavy-duty tasks, such as plowing or pulling heavy loads.
The Allis Chalmers WD45 tractor is equipped with a sliding gear transmission system that features a wet disc clutch. This type of transmission was commonly used in tractors during the 1950s and was known for its reliability and durability.
The Allis Chalmers WD45 transmission system has four forward gears and one reverse gear, allowing for a range of speeds to suit various tasks, its transmission oil capacity is 16.0 L (4.2 US. gal, 3.5 Imp. gal.), The forward speed can reach up to 18.0 km/h (11.2 mph), while the reverse speed can reach up to 5.2 km/h (3.2 mph).
The wet disc clutch in the transmission system uses oil to cool and lubricate the clutch plates, preventing them from overheating and wearing out quickly. This type of clutch provides a smoother engagement, reducing the likelihood of jerking or jarring when changing gears.
Other General Features
The Allis Chalmers WD45 tractor also had a range of other general features that were beneficial to the agricultural sector. It was available with manual or power steering, depending on the farmer’s preference. The mechanical band brakes were reliable and effective, ensuring that the tractor could be stopped quickly and safely. The open operator station provided excellent visibility and ventilation, while the optional Allis-Chalmers Half Cab provided additional protection from the elements.
List Of Serial Number
The serial number of the tractor can be found on the left brake housing.
The serial number of the tractor is written adjacent to the year of its manufacture:
- 1953 – 146607
- 1954 – 160386
- 1955 – 190993
- 1956 – 217992
- 1957 – 230295
