I am surprised at the degree of wear, especially as one gear remained unchanged. I presume material and the sparse lubrication is the basic cause. Has anyone encountered a similar conflict in any other device?
Perhaps for the next API rating they could add the Seven Dynamotor test. But not much chance without ZDP.
Hi Bob,luckily I have an external filter fitted. I found no evidence of particles in the sump oil so hopefully will be ok. Will change oil & filter after 100 miles to be safe. My take on the new gear is a sharp edge on top of the tooth & badly shaped teeth. Added to that a steel gear of bad form will just chew it’s way thru the cast iron. I had no noise from the gears, just found damage when I checked after reading posts on here. As for Autospark, as people had said the unit was acceptable I personally feel that negates some of the blame with Autospark. It would be sad if they & other companies decided not to put money into developing and suppling parts for our cars for fear of litigation.
Just my view. Regards Kevin.
