3.  A job number and name plate is assigned to the motor.

4.  Motor is completely disassembled and all mechanical and electrical parts are checked.

5.  Customer will be contacted with quote for repairs. If repair is approved, a PO# will be issued. If denied, motor will be reassembled and returned to customer at no charge.

  • Motor is tested at no load and vibration test IRD-111 performed.
  • Motor is coupled to Dyno and load tested at 0%, 50%, 100%, and 150% loads.
  • All tests will be documented on a load test report, with a copy supplied to the customer.
  • After all tests are performed, any additional parts, gears, couplings, stuffing boxes, packing €glands, etc., will be inspected and put back onto or with the motor.
