Has anyone ever seen installation/setup literature for these bell swingers?
Deteriming the length of the pushrod and angle of the pusher bell crank in relation to the bell yoke?
The Gollmar patent drawings all seem earlier than the one on MEC 470.
Haven't figured out what the two pair of slots are for in the housing of the pushrod.
The slots are not very long. If they are for pins or screws to prevent the push rod from departing the housing they wouldn't allow much adjustment with the bolt at the top. Was the idea to fit the pushrod length and get it adjusted for proper operation then drill a hole in the push rod thru these slots? Were they to also allow oiling?

All your responses are welcomed. You probably know, Bob D. and I are talking about the same project. Bring it on, because the more we share as a community, the mor we all benefit. Restoration is not an isolated event.

Thanks for the info Kelly.
The big problem I'm having right now is getting the cylinder apart. Being a blind assembly I can't get any force working in my favor. At this point it is pretty full of penetrating oil that seeped in thru the intake port. I'm going to try plumbing a grease gun to it and see if it will hydraulically jack apart.

If you have the time, just soak it in Kroil. I had a helluva time getting 1522's apart originally. Cleaned it up, honed the bore made new rings and pronounced it done. worked great most of the time, but would have fussy periods. We tried regulating air and I finally put a sanding valve in the cab. Always worked well on the first detent, but sometimes you'd have to up the ante for a few seconds. I've seen bulletins that the Frisco roundhouse foreman posted about them. You just have to talk to it nicely.
