Installation 1 Install turret lock assembly (6) and secure using two cap screws (5), new shims (4), two new lockwashers (3), two flat washers (2), and two new self-locking bolts (1). Machine key (30) fits into hole (40) in geared race (41) to locate turret lock assembly (6) properly. Torque cap screws to 248-302 lb-ft. 2 Move manual control lever (15) to LOCKED position and check to be sure that teeth of gear (28) engage teeth of geared race (41) and that pin assembly (18) engages hole in turret lock assembly (6) for LOCKED position. 3 Vary thickness of shims (35) to adjust engagement of gear (28) with teeth of geared race (41). Decreasing thickness of shims brings gear into closer engagement with race; increasing shims thickness moves gear away from race. Shims are available in three thicknesses: 0.001, 0.002, and 0.003 inches (0.03, 0.05, and 0.08 mm). 41 40 4 3 2 1 1 5 6 15 30 18 35 28 6
