The Allis Chalmers 18-30 tractor is powered by a Allis Chalmers 7.6L 4-cyl gasoline engine that provides of horsepower and torque. It has a 4x2 2WD drive configuration and a unsynchronized gear transmission.

Engine

The engine is not specified in the data provided. However, based on the model name 'Allis Chalmers 18-30', it can be assumed that the engine is a gasoline-powered 4-cylinder liquid-cooled vertical valve-in-head engine. The engine is likely to have a displacement of around 460.7 cubic inches or 7.6 liters. It may have a bore/stroke ratio of 4.75x6.50 inches or 121 x 165 mm. The fuel system is likely to be a Kingston L 1.5, and the air cleaner is probably an oil bath type. The engine is rated to run at 830 RPM, and the coolant capacity is around 40 quarts or 37.9 liters.

Transmission

The transmission is a 2-speed unsynchronized gear type. The tractor has 2 forward gears and 1 reverse gear. The drawbar horsepower of the tractor is claimed to be 18 hp or 13.4 kW, while the belt horsepower is claimed to be 30 hp or 22.4 kW. In testing, the drawbar horsepower was found to be 20.55 hp or 15.3 kW, and the belt horsepower was found to be 33.41 hp or 24.9 kW. The tractor is capable of pulling up to 3 plows.

Brakes

The brakes are not specified in the data provided. However, based on the model name 'Allis Chalmers 18-30', it can be assumed that the tractor has standard mechanical drum brakes. The brakes are likely to be located on the rear wheels of the tractor. The braking system is probably operated by a foot pedal, which activates the brake shoes inside the drums. The brake shoes are likely to be made of a heat-resistant material, such as asbestos, to prevent them from wearing out too quickly. The coolant capacity of the braking system is likely to be around 40 quarts or 37.9 liters.



Steering

The steering system of the tractor is powered by an Allis Chalmers 7.6L 4-cylinder gasoline engine. The fuel tank has a capacity of 25 gallons or 94.6 liters, while the auxiliary fuel tank has a capacity of 7.75 gallons or 29.3 liters. The steering system is likely to be a manual steering system, which is operated by a steering wheel. The steering wheel is connected to a steering column, which in turn is connected to a steering gearbox. The steering gearbox is responsible for translating the rotational motion of the steering wheel into the linear motion of the front wheels.

Common Problems

The Allis Chalmers 18-30 tractor is known to have some common problems. One of the most common problems is with the chassis. The chassis of the tractor is known to be weak and prone to cracking. This can lead to serious safety issues, as well as reduced performance. Another common problem with the tractor is with the cab. The open operator station can be uncomfortable for long periods of time, and the lack of protection from the elements can be a problem in inclement weather. Finally, the transmission of the tractor is known to be a 2-speed unsynchronized gear type, which can make shifting difficult and lead to premature wear and tear on the transmission.

What Users Like

Users of the Allis Chalmers 18-30 tractor appreciate several features of the model. One of the most popular features is the 36x6 steel front wheels, which provide excellent traction and stability on rough terrain. Another popular feature is the 50x12 steel rear wheels, which provide additional traction and stability. Users also appreciate the power and performance of the tractor, which is capable of pulling up to 3 plows. Finally, users appreciate the simplicity and ease of maintenance of the tractor, which makes it easy to keep in good working order.
