The chassis and bodies for the above are identical for all purposes. The differences in chassis and body equipment and the load carried when the truck is used for different purposes are noted under tables of equipment on page [161]. All of the above bodies are mounted on a 2-ton Nash truck chassis.

Brief Description, Models 4017-A, 4017-L, and 4017-F.
The chassis of all these models is of 124-inch wheel base and is fitted with a Buda model H-U four-cylinder engine, dry disk clutch, four speed transmission, and a drive to all four wheels through shafts and internal gearing. Although the greater number of units in all three chassis are alike, there are certain structural differences which exist, mainly in the model 4017-F chassis as against the other two. The 4017-F is a two wheel steer chassis, while the others have four wheel steering. All of them use four wheel drive and braking. The models 4017-A and 4017-L are fundamentally the same, differing only in certain details of equipment. Model 4017-L has an acetylene generator and searchlight, and oil side and tail lamps, both speedometer and odometer and an impulse starter on the magneto shaft, while the 4017-A has no impulse starter, uses a Bijur electric generator, storage battery and electric lamps, and is fitted with an odometer only. Aside from the two wheel steering and the necessary changes brought about by it, models 4017-F and 4017-L are practically the same, though a few slight differences exist in the dash, the brake cross shaft and rods and the wheel universals as described in detail in the Ordnance Handbook No. 1999.
The engine is a standard design L-head, Buda model H-U using force-feed lubrication, pump cooling, and fitted with a Stromberg carburetor feeding through cored passages in the cylinder block, and Eisemann magneto, and on the model 4017-A only, with a Bijur generator.
The clutch is of the dry plate type and the drive from it is through an open two-joint propeller shaft to a four speed sliding jaw-clutch type transmission. From the latter extend two-joint propeller shafts, one forward and one rearward, to internal gear-drive axles. The live member has exposed axle shafts extending from it, and the ends of these shafts are fitted with a universal joint and a spur pinion, the latter meshing with an internal gear bolted to a disk steel wheel. All the wheels are interchangeable and are all driving and steering wheels in models 4017-A and 4017-L, while in the model 4017-F only the front wheels steer.
A complete description of the 2-ton truck chassis, models 4017-A, 4017-L, and 4017-F, with instructions for care, maintenance, and operation, is given in the “Handbook of the 2-ton Chassis Nash Models 4017-A, 4017-L and 4017-F,” Ordnance Pamphlet No. 1999.
HOW TO DRIVE.
Before starting an engine the driver should see that the gear shift lever is in neutral position and that the emergency brakes are set. The spark lever should be set at the proper position. If battery ignition is used it is best to have the lever in full retard position, as the spark will occur no matter how slow the engine is cranked. If magneto ignition is used the lever should be advanced slightly as a hotter spark is obtained in the advanced position than in the retarded. There is less probability of a kick back when starting on magneto since it is necessary to turn the engine at a fairly high rate of speed, approximately 100 R. P. M. to generate sufficient current to produce a spark.
