No, That's some BS that got pushed off on people because for a long time the parts being sold were not to correct spec. It doesn't take very long at all for a fresh 915 to break in. The number one key here is that the replacement dog teeth must have a 9 degree backcut on them. German OEM dog teeth don't have it. R&S replacement teeth didn't have it until about 2 years ago. Literally, for 2 decades, 915 gearboxes have been getting rebuilt with out of spec parts.
