Just installed engine, and completed engine Alignment all went well after a few issues. Thanks to some great advice from this forum.

Just one quick question. I replaced all the mount hardware but I was wondering what is the purpose of the Fiber Washer?

I have a perfect grease marks and alignment tool slides in with two fingers. When i reached back in there i could spin the fiber washer..

Now I took Don's advice and made sure weight was evenly distributed by lifting motor up and as soon as I got it off mounts I adjusted the front mount.

I have also been using a Caliper to check high adjustment. Left side 0.870 Right Side 0.880.

The concern is the movement of the fiber washer??
