ARMY TM 9-6115-464-12 AIR FORCE TO 35C2-3-445-1 NAVY NAVFAC P-8-624-12 NOTE Excessively worn tie rod ends (10 and 16) and king pins (14) maybe indicated by excessive and uneven wear on the front tires. (e) The generator’s front end must be raised until the front wheels are dear of the ground in order to check excessive wearing of king pins. (See paragraph 5-19 for jacking procedures.) NOTE Care must be exercised when checking excessive wear on king pins to avoid mis- taking wheel bearing play or loose wheel for excessively worn king pins. (f) Replace excessively worn king pins and tie rod ends. (2) Adjustment. If tie rod ends have been replaced, or adjustment is deemed necessary, adjust the tie rods using the following procedures: (a) Adjust the tie rod assemblies to as near their original length as possible, with an equal number of threads showing on each tie rod end (10 and 16). NOTE With the tow bar aligned with the center line of the generator set, a preliminary check can be made to see if the tie rod assemblies are approximately the right length. (b) (c) (d) Install the tie rod assemblies (31) with bolts (3 and 9) and nuts (2 and 8). With the tow bar aligned with the centerline of the generator, and anchored so that it will not move, measure the distance from center to center of the tread of the two front wheels, in front of the wheels. Measure the distance from center to center of the tread of the two front wheels, behind the wheels. NOTE There is no tow in, therefore, these distances should be the same, (e) (f) If they are not identical, adjust tie rods until they are identical. The distance from the center of the front axle to each wheel must also be the same. With the wheels on the ground, and tires evenly inflated, a taut string from front to rear of the wheel mounting kit should touch the sidewall of the aft and forward curvation of both front and rear tires simultaneously, as near the hubs as possible. (3) Lubrication. (a) Lubricate all grease fittings (11, 12, and 17) on both sides of the wheel mounting kit with grease (GAA). (b) Lubricate tow bar mechanism and safety chain with an oil can. c. Rear Axle Assembly. (1) Visually inspect parking brake handle for insecure mounting, cracks, corrosion, and other damage. (2) Inspect brake control rods for cracks, corrosion, bends and signs of wear at joints. (3) Lubricate brake linkage with an oil can. 5-37
