For base assembly and motor mounting, the mounting bolts must be tightened to prevent changes in alignment and possible damage to the equipment. It is recommended that a washer be used under each nut or bolt head to get a secure hold on the motor feet. As an alternative, flanged nuts or bolts may be used. The recommended tightening torques for medium carbon steel mounting bolts, SAE
Grade 5, are listed below in Table 1. For recommended tightening torques of other hardware on the motor see tables 4A, and 4B in the Tightening Torque section of this book

Accurate mechanical lineup is essential for successful operation. Mechanical vibration and roughness in
running the motor may be an indication of poor alignment. In general, lineup by straight edge across,
and feeler gauges between coupling halves is not sufficiently accurate. It is recommended that the
lineup be checked with a dial indictor and checking bars connected to the motor and load-machine shafts.
The space between coupling hubs should be maintained as recommended by the coupling
manufacturer. Shaft offset should not exceed 0.002”. Angular misalignment should be less than 0.002”.

The application of pulleys, sheaves, sprockets, and gears on the motor’s shaft is shown in NEMA Standard MG1-14.07. The application of the Vbelts dimensions for alternating current motors is in
MG1-14.42. V-belt sheave pitch diameters should not be less than the values shown in Table 14-1 of NEMA
MG-1. Sheave ratios greater than 5:1 and center-tocenter distances less than the diameter of the large
sheave should be referred to the Company. Make certain that the minimum allowed diameter of the
motor pulley and the maximum belt tension are not exceed because an excessive pull may cause bearing
trouble and shaft failures. Tighten belts only enough to prevent slippage. Belt speeds should not exceed 5000 feet per minute (25 meters per second). When V-belts are used, sheave ratios greater than 5:1 and center-tocenter distances less than the large sheave shall not be used. The dimensions of the belt pulley are to be determined according to the kind of belt, transmission  and capacity to be transmitted. Vent holes have to be kept free and required minimum distances are to be observed in order not to obstruct the flow of cooling air. In addition, make sure that the discharged hot air is not re-circulated into the motor.
