OPM-142/D

WARNING: PERSONAL INJURY & EQUIPMENT 

DAMAGE

Trailer may tip over and cause injuries if wheels are not 

spaced far enough apart.

  C. The trailer height and mounting position of the 

    generator on the trailer should enable aligning the 

    drive shaft (tumbling bar) in a straight or nearly straight 

    line between the power take-off and generator input 

    shafts. Misalignment must be less than 15 degrees 

    during generator operation, even though the 

    mechanical design of the tumbling bar would allow 

  greater 

misalignment.

  D. The generator mounting area of the trailer bed should 

    be flat. All four generator mounting pads must rest 

    firmly on the trailer bed. Install shims if necessary to 

    even out the bed under the mounting pads, then bolt 

    the generator firmly in place.

INSTALLATION

Note: PTO mounting holes are .75”. 

FOUNDATION MOUNTING

Mount the generator on a foundation if it is to be used as 

a permanent or standby power source. When planning a 

foundation, consider the following points:

  A. The foundation location should enable aligning the 

    drive shaft (tumbling bar) in a straight or nearly-straight 

    line between the power take-off and the generator 

    input shaft. Misalignment must be less than 15 degrees 

    during generator operation, even though the 

    mechanical design of the tumbling bar may allow 

  greater 

misalignment.

  B. The foundation must be solid enough to absorb 

    generator starting and reflected load torque during 

  operation. 

  C. The foundation surface should be flat.

  D. Space is required around the generator for mounting 

    switching devices, making connections, and for 

  servicing.

 

  E. For dimensions needed for your specific generator, 

    please refer to it’s outline drawing. The hardware 

    needed is dependent on your distinct application.

  F. All four generator mounting pads must rest firmly 

    on the foundation. Install shims if necessary to even 

    out the foundation under the mounting pads, then 

    bolt the generator firmly in place.

TRAILER MOUNTING

Mount the generator on a trailer if you plan to use it as a 

portable power source. When selecting or building a trailer 

to mount the generator, consider the following points:

  A. The trailer construction must be strong enough to 

    support the generator.

  B. The design of the trailer must enable the trailer to 

    remain stable during operation, and to resist tipping 

    caused by generator starting and reflected load torque.
