Hi Norm,
You're right. Parts manual and price lists are silent as to these bolts.
I took an assembly apart. They were 10-32 thread with AN320-3 shear nuts and AN320-2-2 cotter pins, and appear to be AN3-10, with a nominal length of 1-1/32" and a grip of 5/8", drilled shank only. The originals had a large "X" on the head, with an upper case "E" above and below and a dot left and right (for which I have no cross-reference).
While the Ercoupe Parts Listings available to me do not list these bolts as having been stocked by Sanders, both Forney and Alon do. Mooney used another type of rudder bellcrank.
For an authoritative answer, call Univair and speak with Craig Baldwin. Ask him to look at drawing 415-52424 and/or F-52424. There should be a call-out as to the bolt and nut specified by each manufacturer. Let us know what you learn.
Regards,
WRB

Hi,
I have successfully removed my horizontal stabilizer. We looked at the rudder bellcrank and noticed some play in it. I replaced the nuts and bolts that hold the top and the bottom half of the bellcrank together. This eliminated the play in the bellcrank.
I would like to now be able to confirm that I have the correct type of AN hardware in the assembly. Unfortunately the parts manual does not show this hardware.
If anyone can let me know what type of nuts and bolts are supposed to go in there I would greatly appreciate it.
Thanks again
Norm Decou
