RV-4 Wheelpant Bolt

olyolson · #1 07-21-2018, 09:38 AM

My RV-4 wheelpants are mounted to the wheels with undrilled bolts. Even though I have lock washers on them, these I understand are supposed to be drilled bolts safety wired to the wheel pant bracket. I am out of town and do not have access to the plans set. Would like to order them online from Acft Spruce so I can have them available when I get home.

Any RV-4 guys out there that could help out with a part number for the 2 drilled bolts I need? I would’ve called Van’s but they don’t work on Saturday and everyone is at Oshkosh anyway.

Thanks

I don't recall the required grip length bolt you need, but you can order a set of 1/8 inch grip and 1/4 inch grip, the numbers are:

AN3H-4A and AN3H-5A. The first is 1/8 grip, second 1/4 grip

The "H" after the 3 denotes drilled head.

Plans show un-drilled AN4-11A. Drilled would be AN4H-11A

Oops guess I should have clarified. Mine are the two piece pressure recovery wheelpants. The bolt is the outside one that goes through the bracket and attaches the wheelpant bracket to the threaded outside hole of the big axle nut (VA-106).

Thanks for the quick responses!

AN4H-5A, AN960-416, saftey wire head of bolt to cotter pin in VA 106.
