Book Excerpt: 1948-1952 Ford Tractor Model 8N Service Manual DESCRIPTION AND SPECIFICATIONS 111. DESCRIPTION
The Model 8N Ford tractor is provided with a steering gear assembly of the automotive ball nut type. It is a highly efficient, easily serviced unit which is readily adjustable to compensate for wear. This steering gear has a low driver fatigue factor because of easy steering and a minimum of road shock. The tractor is equipped with a four forward and one reverse gear transmission. The transmission contains constant-mesh helical gears, assuring quiet running and providing for long life. The power take-off is driven from the transmission countershaft. A power take-off adapter is available to extend the shaft when such extension is necessary for fitting certain implements. The adapter meets the American Society of Agricultural Engineers' specifications for a standard tractor hitch. Any implement built to these standards may be hitched to the Ford tractor without the purchase of additional accessories. The tractor hydraulic system consists of a piston pump driven directly by the power take-off shaft, and a self-contained hydraulic unit which includes the ram cylinder and control linkage. The hydraulic pump and unit are located in the center housing and employ the transmission oil as the hydraulic fluid. This design reduces the possibility of external oil leakage, and greatly reduces repair costs.

The disassembled hydraulic pump is shown in fig. 22. a. Disassembly. Remove the safety valve and check valve. Remove the cotter pin which secures the valve control lever to the base. Remove the cotter pin and clevis pin which secure the exhaust valve to the control lever. Remove the control lever. Remove the four cap screws which secure each valve chamber cover (fig. 22) to the base. With a soft hammer, tap the valve chambers off the base. Lift the cam and piston assembly out of the base. Remove the power take-off shaft bushing (figs.22 and 26) from the base. Remove the clamp from each valve chamber cover. Remove the two spring seats, outlet valve springs, outlet valves, inlet valve springs, inlet valves, valve guides, and valve guide seats from each valve chamber cover with a pencil as shown in fig. 23. b. Inspection and Repair. Clean all parts thoroughly in a cleaning solvent and blow dry with compressed air. Scrape gasket surfaces until all pieces of old gasket are removed.

This manual is perfect for the restorer or anyone working on one of these tractors. Clear illustrations show exploded views as well as component details and more.
