The Solution

Cyrus-Bradford engineers inspected all the components recording details and specifications. The main gear components – damaged in service were inspected and gear geometry calculated. Engineering drawings prepared & approved prior to manufacture. Replacement parts were supplied in correct materials and heat treatment to suit the application.

The unit was re-assembled, test run & certified at Cyrus-Bradford workshops with the client in attendance. Condition monitoring values were said to be to finer limits those previously achieved by OEM.
