Information:

Wear Fatigue
An estimation that determines the degree of wear/fatigue can be determined by rating the amount of time spent in limited speed ranges opposed to spreading the load through the normal operating range.Normal
If an operator uses every speed range regularly during the course of the work, then the transmission will experience Normal wear/fatigue.High
If an operator uses a limited speed range, then the transmission will experience High wear/fatigue. The range of speed selection is dependent on the machine model and application. Example:A motor grader can have, depending on the model, six or eight forward speeds. During its normal operation only the lower speed ranges are frequently used for any prolonged period of time. So it is Normal for a motor grader to not use its full range of speeds evenly.The Challenger 65 and 75 during tilling application, track-type tractors during ripping application, and wheel tractors (824 and 834) have similar wear/fatigue characteristics to the motor grader. Example:An off-highway truck traveling on a long steep grade using the lowest speed range will experience High wear/fatigue.Scrapers and articulated dump trucks have similar wear/fatigue characteristics to the off-highway truck.Shift Frequency
Frequent shifting accelerates wear. If there has been a high frequency of shifting, accelerated wear might be apparent.Note the frequency of shifts as compared to normal for a given machine model in a normal application.Normal
If there has been a normal frequency of shifting, normal wear has occurred. Example:Motor Graders undergo very few speed changes during their normal operation.The Challenger 65 and 75 during tilling application, track-type tractors during ripping application, and the larger models of the wheel loader have similar wear/fatigue characteristics to the motor grader.High
If there has been a high frequency of shifting, accelerated wear might be apparent. Example:Off-Highway Trucks (when using short haul roads) have a high shift frequency.Wheel Tractor-Scrapers have similar wear/fatigue characteristics to the off-highway truck. Instead of the shift frequency wear characteristics occurring in the speed gears as in the previous examples, there are machines that have wear characteristics occurring in the direction gears. These machines include track type tractors and the smaller models of wheel loaders.Operator Technique
Operator technique is very important to the life of a transmission. The better the operator, the less wear imposed upon the transmission.Excellent
An operator of a track type tractor who stops the machine before making directional shifts and uses the decelerator under load is rated Excellent.Average
An operator who makes all straight directional shifts, and makes no split shifts or split directional shifts without using the decelerator is rated Average.Aggressive
An operator who occasionally makes split directional and straight directional shifts at full throttle (without using the decelerator) and consistently pushes the machine to its limits is rated Aggressive.Abusive
An operator who often makes split directional and straight directional shifts at full throttle (without using the decelerator) is rated Abusive. For an evaluation of the transmission with an abusive operator, your service department must be contacted for assistance.Operator/Shift Variation
The number of operators and working shifts directly affects transmission life. Multiple operators working multiple shifts will
