The maintenance manager of a bearing manufacturer has asked you to calculate the

reorder point of a spare part item. She has provided you with the following information to

facilitate your calculations. The cost of the spare parties$100. The cost of earning inventory

is 20% of the cost of the part. The cost of placing an order is$40 for which the annual

demand is 100,000 units. The average tad-time for replenishment is two weeks and the

(CMMS)

5% Creating work order estimates

15% Researching what spare parts are needed and where to find them

25% Expediting materials that have not come in yet

5% Creating material kits for future jobs and maintaining the kitting area

1% Creating formal job steps in the work order record in the CMMS

10% Checking on field progress of the larger jobs

and hire another designer draftsman

C. Increase the planning horizon and improve the quality of bills of material in the

computerized maintenance and materials system

estimation methods

WM 19

Motor Circuit Analysis (MCrA) on a low (450-600) voltage 3 Phase motor reveals

significantly higher capacitance-to-ground than baseline values. Resistance-to-ground

readings are good. What does this indicate and/or what should you do?

A. The motor contains abnormally high moisture and/or conductive contamination. Continue

normal operation, but plan follow-on MCrA readings and possible corrective action.

B. Remove motor-from service and send to shop to be cleaned, dried, dipped and baked,

since this is the surest way to corrective problem.

C. Do not start the motor. An "explosive" shorting condition could cause near instantaneous

winding failure.
