Combines 2366 high wear

Thickness of steel has very little to do with its wear characteristics. Keep in mind that when replacing components there are 2 options one being the high wear "rice" option. If your machine was ordered with that from the factory and the componets were replaced with standard parts that would explain why the first ones lasted 1000 hours and the replacements only lasted half as long. Either that or you need to grow lower yielding crops.

We bought a Burvee Bubble up auger and that has reduced the wear on the clean grain components alot. Wouldn't want to run without it.

they al just wear out the same way extennded wear is better but it goes as well good luck
