0431141 bell crank stop bolts and 0430010 shims

Post by briantrani »

Bought back my dad's 1947 140from someone who kept it in pieces 30 years. I am new new to this but looking for help assembling tail.

Parts Manual Figure 13-12: #0431141 bellcrank stop bolts (possibly #NAS428H3A12 from previous post) qty2

Parts Manual Figure 13-24 and 14-48: washer/shims #0430010-1 (0.020"), #0430010-2 (0.032") qty as required

I last flew this airplane in high school. Thanks for helping me get her back in the air.

Sooooo, does anyone know where I can find this hardware or have tips on cross referencing the cessna parts numbers from the parts catalog?

I did read on a previous post that the stop bolts are special in that they will not have raised markings. That makes sense.

Thank You!!

The NAS428 bolts have recessed markings and slightly domed heads. They are intended to be stop bolts. I don't think they were available in 1946. The flap stop bolts on my plane were AN3 bolts that had been (re)threaded up to the heads and the markings were ground off. I can't say for sure if they were original, but I'd take a reasonable bet on it. (That's why they have Cessna part numbers.) I'd use the NAS428 bolts without any concerns.

As far as the shims go, AN960 washers would be fine, except the thinnest ones you can get are AN960-10L and they're .032. If you need thinner than that I don't know what to suggest other than punching them out of brass shim stock.

John - thank you for making my first post/question a success.

I really appreciate your help.

I can only find one other 140 owner near me and he's 100 miles away. Gosh I'm excited to find more.

Thanks again!
