If the piston of the cylinder is in its end of a travel position before the sprocket shaft is in its correct position, remove one 1P3052 Link from each side of tooling (A). Put pressure on the shaft again. 3. With the pressure still on the sprocket shaft, tighten nut (1). Measure dimension (X). Dimension (X) must be 9.5 .062 in. (241.3 1.57 mm).4. After nut (1) is tight, hold it in position as follows: a) In one of the grooves of nut (1), drill a .312 in. (7.92 mm) hole through the nut and .62 in. (15.7 mm) deep in the shaft. Install pin (2) in the hole. Install ring (3) to hold pin (2) in position.end by:a) install final drive cases, gears, and hubs
