Ford 8N

This is the main difference between the 8n and 9n Ford tractors; and as you’d expect, the 8n has a number of improvements that make it better than the 9n. One such improvement comes in horsepower. The engines on the 8n tractors are generally a bit more powerful than those on 9n tractors.

The Ford N-series tractors were a line of farm tractors produced by Ford between 1939 and 1952, spanning the 9N, 2N, and 8N models….

The 8N features a 23.22 belt horsepower with a 27.32 maximum. The tractor has 92 ft-lbs of torque, reached at 1,500 rpm.

The governor itself uses a rotating mass applied against a spring to adjust the carburetor throttle shaft and to regulate the engine speed around a set point established by the throttle lever position. Consequently, the first step in governor inspection is checking for any signs of malfunction.

For a new or rebuilt carb, I use the following bench adjustments to start:

1. 1—Turn the IDLE SPEED screw all the way out and then turn it in slowly until it just makes contact with the pin and the throttle plate is fully closed.
2. 2—Turn the IDLE MIXTURE screw all the way in and then back out ONE turn from the bottom.

Terms in this set (28) What position should the speed control be in when adjusting the governor? Which ring provides a controlled film of oil to lubricate the compression ring? The governor spring is the only force on the throttle shaft when the engine is not running.

A pilot jet is a carburetor component that meters the flow of air into the idle circuit of the carburetor. Which is the least likely cause of an engine to hunt and surge at top no-load speeds? A completely blocked high-speed air bleed can commonly cause an engine to run very rich under load.

In the case of a hydraulic governor, a plunger is present on the power piston shaft and on the drive shaft. This plunger moves in the same direction as the power piston. The downward movement of the power piston due to an increase in engine speed also moves the compensating plunger downwards.

A “passive” evaporative vent system is only effective when the engine is running. For proper operation of all active evaporative systems, fuel supply lines must contain liquid fuel, not vapor, and evaporative vapor lines must be open for vapor withdrawal from the tank and not obstructed with liquid.

In ideal situation, amount of fuel given to the injector is fixed but in some cases such abnormality arises hence rpm get changed. Hence of the options available, a blocked carburetor bowl is the least likely cause for engine hunt.

One known passive technique of venting or balancing the pressure within a fuel tank consists of a fuel cap that has inlet and outlet vents. Although the fuel cap may be appropriately sized, the fuel cap is incapable of minimizing fuel vapor emissions into the atmosphere.
