    Default Another gear pattern question...

    Do you guys think this is acceptable or do you think the pinion needs to come in more? Any advise is greatly appreciated. Name:  20190410_094007.jpg

    Referencing my gear pattern chart, it appears you need less pinion shim. Pinion running too deep in teeth of ring gear.

    My opinion as well but I’m no expert and have never done it.

    looks about right to me...I've set a few of the gears up with that wear pattern...if you have it to close to the end of the teeth , there's not much meat there and you will start breaking or cracking the ends of the teeth.
