We offer the service of Reconditioning bogies for Komatsu D375A-3, 6 or 7 roller track frames.

We have the male and female bogie frames brought back to standard by buiding up the faces on the working surfaces between the two and then machining them back to specification. Then the bore is checked on both units and if necessary are built up and machined. A brand new genuine Komatsu pin assembly is pressed in to complete the assembly. All holes are re-tapped and new rubber pads are fitted.

This is how we recondition the trunnion balls from a Komatsu Dozer D375A-3/5.

We use the base of the worn trunnion ball but we cut off the ball and its shaft. We then machine a new ball and shaft out of EN19. This gets sent for case hardening. The base gets machined to suit the outside diameter of the shaft. Once completed the ball and shaft is pressed into the base and then welded together.

Experience with the reconditioned units reveal that wear life is superior to a new unit.
