Right angle gearboxes must be mounted on a rigid, structurally sound baseplate. Ensure that right angle gearbox mounting pads rest evenly on the baseplate. The use of shims may be required to avoid housing distortion which could alter the gear mesh or cause premature bearing failure.
The right angle gearbox may be driven by direct coupling, flexible coupling, or V-belt drive. Couplers should require only a light force to install. The drive line must be accurately aligned within the equipment manufacturer's requirements to limit operating loads and minimize thrust loads on the right angle gearbox shaft. V-belt drives must be mounted close to the housing to minimize excessive overhung loading which could result in early bearing or shaft failures. Sheaves must fit correctly. At installation, a tight forced fit could move the shaft from its normal position and cause internal damage. A loose fit could induce excessive vibration during operation and cause shaft damage or breakage.

Warning: When mounting the right angle gearbox, the buyer is responsible to properly determine the quality or grade of fastener, thread engagement, load carrying capacity, and torque requirements.
Warning: The buyer is responsible to provide protective shields over all external rotating parts, couplers, or shaft extensions mounted on or with the right angle gearbox. Protective clothing must be worn when installing or maintaining the right angle gearbox and operating system. Initial operation should be carried out under no-load conditions. Before applying power to the right angle gearbox installation, review the following:
1. Check tightness of mounting bolts.
2. Check for proper oil level in right angle gearbox.
3. Be certain that tools, debris, etc., are clear from rotating parts.
4. Rotate shafts by hand. If they do not rotate freely, check for uneven mounting, coupling misalignment or excessive belt tension.
If all tests are satisfactory, make connections to shafts, ensure that all safety devices are in place, and begin operation.
