Does anyone know what the specific washer type/number is, used for the two AN8-35A mast cheek plate bolts, might be. All the manual says is "Hardened Washer". The ones on my gyro are of several different types and I'm sure not all are what came with the kit. They are 1" O.D.

A AN washer for a AN8 bolt is, AN960-816. they a not hardened nor they 1" O.D.
You can buy hardened washers in all sizes through the internet, every company that makes and sells hardware (washers) has there own product PN.

Ok, thanks J Bird. Knew about the AN960-816, but didn't know if there was an AN 1" dia. Version.

Get some oversized AN 1/4" I.D. washers, and drill them to 1/2"

I also drill them to 3/8" to back up my Heim rod end eyes.

Safe flying!

Over here, if you want high grade or high tensile washers, they are referred to as 'machine spacers' .... they come in very accurate thicknesses... :yo:
