floating rotor bobbins and bolts questions
Hi all,
My bobbins and bolts are separate pieces. the bobbins fit the rotor slots and are 0.004" thicker than the slot. what is a normal amount of rotor float? is 0.004" in the range of normal?
Also, I am planning to replace the bolts and jet nuts. I am unclear what type of bolts these are or what I should use. Grade 8, AN, NAS or something else? They are 1/4-28 thread and I need a minimum grip (shank) length of 0.335" or a maximum of 0.69". Overall length (excluding the head) should be 1.00", or within a few hundredths.
I found AN4-10A on Pegasus or NAS1104-11 on Skybolt or NAS6204-11 on Aircraft Spruce. Aircraft Spruce calls them NAS shear bolts?
Any recommended assembly lubrication or anti-seize?
Thanks for any input / guidance,
Mike
