The new dimensions for the opening that supports the front shaft assembly should be 94.666 0.013 mm (3.7270 .0005 in). The new dimension for the opening that supports the front of the gear should be 37.994 0.013 mm (1.4958 .0005 in).
The 162-0157 Housing is part of the 162-0161 Housing Assembly that is contained within the 162-0148 Drive Group. The new dimensions for the opening in the 162-0157 Housing that supports the rear of the shaft assembly should be 28.636 0.013 mm (1.1274 .0005 in). The new dimensions for the opening that supports the rear of the gear should be 37.994 0.013 mm (1.4958 .0005 in).
The 162-0156 Housing is part of the 162-0160 Housing Assembly that is contained within the 162-0149 Drive Group. The new dimensions for the opening that supports the rear of the shaft assembly should be 28.636 0.013 mm (1.1274 .0005 in). The new dimensions for the opening that supports the rear of the gear should be 37.994 0.013 mm (1.4958 .0005 in).
The shaft assembly is supported by the larger 162-0152 Front Bearing and the smaller 162-0150 Rear Bearing. The 162-0155 Gear is supported by two 162-0151 Bearings, with one at either end. The new specifications for each of the new bearings are listed below.
162-0151 Bearing (1) The outer diameter of the shaft is 34.900 0.013 mm (1.3740 .0005 in). The inner diameter of the assembled bearing is 35.003 0.052 mm (1.3780 .0020 in). The clearance between the bearing and the shaft assembly should be 0.038 to 0.168 mm (.0015 to .0066 in).
162-0152 Bearing (2) The outer diameter of the shaft is 88.500 0.013 mm (3.4842 .0005 in). The inner diameter of the assembled bearing is 88.675 0.073 mm (3.4911 .0029 in). The clearance between the bearing and the shaft assembly should be 0.089 mm to 0.261 mm (.0035 in) to (.0103 in).
162-0150 Bearing (3) The outer diameter of the shaft is 25.400 0.013 mm (1.0000 .0005 in). The inner diameter of the assembled bearing is 25.490 0.052 mm (1.0035 .0020 in). The clearance between the bearing and the shaft assembly should be 0.025 to 0.155 mm (.0010 to .0061 in). If the specifications of any of these components are not within the given range, then the components should be replaced.
