Minimum clearance required is 6 inches above, in back of, on both sides of, and 4 inches underneath wheel. Chock blocks. Each to consist of 6- x 8- x 24-inch block cut 45 degrees on one end and 35 degrees on the other end. Nail each block to a 2- x 8- x 47-inch piece of lumber with eight 20d nails so that two blocks will have the 35 degree end forward, and two blocks will have the 45 degree end forward. Place the 45 degree end under the front treads and the 35 degree end under the rear treads. Nail to car floor with eight 20d nails. Side stakes, 18 inches long, sized to fit stake pocket. Extend clamps 2 inches below stake pocket and 8 inches above car floor. Locate in the stake packets nearest the center of the vehicle. Side blocks. Each to consist of two pieces of 2-inch x width-to-suit x 10-foot lumber. Locate against crawler treads, centered along ground contact length. Secure bath pieces to floor with ten 30d nails. Wire rope, 5/8-inch. In a complete loop, apply from pintle through front and rear shackles to side stake pockets as, indicated in figures 7–1 through 7-3. Place thimbles at the bottom of each stake pocket and through each shackle. Overlap wire rope at least 24 inches. Clamps, 5/8-inch. Fasten each wire rope with four clamps spaced about 3-1/2 to 4 inches apart. Cribbing, 4- x 6- x 37-inch, solid block of lumber. Place under dozer blade.
