Gentlemen,
I'm finishing up replacing all the control cables, pulleys, turnbuckles, etc. and I'm a bit confused at the aileron bellcranks
The '48 IPC shows AN3 bolts but the fittings are all drilled 1/4 inch (AN4 holes). There is no mention in the IPC of bushings, but I have found bushings on most (but not all) of the bolts I'm removing.
The fitting in the photo has a bushing jammed into it, but the replacement cable has no such bushing.
Are bushings typical on these bolts or are the AN3 bolts supposed to wallow around in 1/4 inch holes?
Thanks,
Gareth.

There are spacer bushings in the clevis assemblies that the AN3 bolts pass through. I lubricated them as I assembled.

Thanks Kevin,
It would be nice if they had included such inconsequential details in the IPC!

Re: Aileron bellcrank bolts
Take at look at IPC Figure 6, Items 40, 41, and 42 (bushings).

Never would have guessed!
The bushings appear to be part of the bell crank/airframe rather than the rigging, but the nuts and bolts are part of the rigging.
