Thanks Piston Slapper so much for the reply. We could not get a definitive answer as to why the gear broke despite the fact that we were able to prove that we used Kendall oil and Wix oil filters exclusively.
We change the oil and filter every two weeks so I do not believe that it was neglect on our part. We have eight Walkers with either the Ch20 or Ch23 and never had a failure like that. We routinely get between five and six thousand hours out of the Kohler CH engine with no major repairs.
Are you partial to Kohler oil and Kohler filters?
