P&H final drive upgrade

Designed to allow the drive shaft to be removed from the out-board side of the crawler frame on CAT 7495 and Bucyrus 495 series shovels

P&H lower works systems have been proven in severe-duty applications. This same engineering and manufacturing expertise has now been applied to the design of parts for non-P&H undercarriages. The Final Drive upgrade allows the drive shaft to be removed from the out-board side of the crawler frame on CAT 7495 and Bucyrus 495 series shovels. This eliminates the need to decouple the motor and remove the transmission to replace the final drive shaft, dramatically reducing the maintenance downtime associated with replacement of these lower works components.

• Extended component life — increased spline length between tumbler and shaft interface reduces stresses on the spline 
• Additional thrust support — oversized thrust surfaces mounted to the crawler frame promotes increased bearing life by removing axial loads transferred through the bearing capsule  
• Smart design — sealing arrangement engineered to help keep dirt out and grease in place to keep bearings running clean  
• Decreased maintenance time — once installed, it is no longer necessary to realign and recouple the transmission and motor
