Guys,
Hoping someone whose got extensive transmission experience (AllanD!) can look at a gear and tell me what would cause this type of wear.
It's a distributor/oil pump drive gear on a non-RBV.
It's well covered in oil so I don't think it's lubrication.
Could it be poor tooth profile design, poor machining tolerance or substandard materials?
If this gear is worn this way and I replace it, is the camshaft gear it mates to likely worn and will it just wear the new driven gear the same way?
I've got my fingers crossed that the other gear is significantly harder, wore down the imperfections on this one and additional wear has ceased. No traces of metal in my oil so maybe it's been this way for a while?
