Re: R-4C PTO cleaning, stuck on this part!!

 

Justin:

I've done many PTO's in the past, and every one was removed from the radio...both rx and? tx.? Note that you will have to remove the front panel to get the PTO out.

BTW, the "Smooth and Silky" PTO article as written by Neil, K1VY.? Ron posted that to his great Drake site.? I'd recommend?going through another article that I wrote on PTO removal that you can find on Ron's site in the Hamvention presentation for 2018.? The link is here and starts on Page 15.? I tried to cover some things that Neil left out...like how to remove the front panel and what tools you will need.....and a few "gotch ya's".



With the front panel removed, you have an opportunity to clean between the front and sub-panels, the dial window, and make sure the dial window goes back on on the front side of the sub-panel.? Early C-lines had it installed on the rear of the sub-panel, which made it more prone to dial rub.

Also...there are at least 4 different mechanical variations of the R-4C PTO.? Make sure you take a picture at EVERY step of its disassembly!? Lay the pieces out on a towel IN ORDER and snap a pic at each step.? If the pics in either my article or Neil's show a different PTO than yours, and you get stuck...get in touch with me as I may have additional pics that could help.? Of the 4 types, I have had three of the versions apart.? One is extremely rare and you are unlikely?to come across that one.

Good luck!

Doing the Smooth and silky PTO cleaning preceture to my R-4C by WB4HFN?

I¡¯m up to the disassembly part where the PTO can be removed from the receiver as far as the service loop will allow, however, the long metallic part of the shaft is unable to clear the front face of the cabinet round cut out hole. In some of the pictures on the site, looks like this metallic shaft was removed and just the brass part of the shaft is left.?


if I can remove this metal shaft part from the brass part, then I would be able to remove the PTO and proceed.?

does anyone know if this can be removed and how it is removed??
