Congratulations. You've joined an exclusive club that includes writers like: Edward Abbey John Ashbery, Saul Below, Johnny Carson, Joan Didion, Bernard Kalb, Elia Kazan, Helen Keller, Grace Metalious, Arthur Miller, Carl Reiner, Fred Rogers, Rod Sterling, George Sheehan, and Wallace Stegner.

I've got over 60 typewriters in my collection and the KMG is my favorite, especially when it's clean and properly adjusted. I've got one each in Royal Elite and Royal Pica typefaces they're so nice.

KMG controls diagram: https://site.xavier.edu/polt/typewriters/RoyalKMGdiagram.jpg<br /> Richard Polt's site doesn't have a manual (yet) for the KMG, so pull the manual for the Royal KMM instead. It was the model made just before the KMG and should be functionally identical. The Royal HH which followed it was also broadly similar. https://site.xavier.edu/polt/typewriters/tw-manuals.html

The spools for the standard Royal typewriters (Ten, H, KH, KHM, KMM, KMG, RP, HH, FP, Empress, 440, 660, etc.) have a custom metal mechanism for their auto-reverse. The spools are known as the T1 (which is the same as General Ribbon part # T1-77B , T1-77BR, and Nu-Kote B64.) If winding on universal 1/2 inch wide ribbon onto them, remove any eyeletes which aren't needed and may interfere with the auto reverse. https://www.youtube.com/watch?v=TMDfGkKqbgE

Incidentally when browsing YouTube for repair videos, the mechanics of all the Royal standards (listed above) are all incredibly similar if not exactly the same, so search beyond KMG to find solutions.

Don't get liquids or water on these as it will seep inside and discolor or damage the paper legends. They're replaceable, but it requires a special tool and/or lots of patience. Incidentally, these were the last US manufactured typewriters with glass keys.

Royal Typewriter KMG Mainspring Drawband Tightened Adjusted Tension by [[Phoenix Typewriter]]

On the left rear corner underneath the carriage when moved to the right, one can easily see the mainspring and drawband assembly. Just behind it is a worm drive operated by a screw. Turning this screw counterclockwise will advance the worm drive to the left and increase the tension on the mainspring.

Known historical users of the Royal KMG:

• Edward Abbey
• John Ashbery
• Saul Below
• Johnny Carson
• Joan Didion
• Bernard Kalb
• Elia Kazan
• Helen Keller (may have been a KMM)
• Grace Metalious
• Arthur Miller
• Carl Reiner
• Fred Rogers
• Rod Sterling
• George Sheehan
• Wallace Stegner

Good Enough Is Very Fine: Royal KMG Tabulator Issue by [[maryech]]

Carriage on a Royal KMG was grinding, so Mary disconnected the spring on the brake gear for the tabulator rack to fix the issue.

The brake gear on Royals isn't meant to be engaged during normal typing operation.

Royal Strengthen Shift Springs KMM Typewriter by [[Phoenix Typewriter]]

I picked this up from a repair manual, but good to see my reading was correct.

Forming the tabs on the shift assembly inwards will increase the tension and responsiveness of the shift assembly on older Royal standard typewriters.

Royal KMM KMG Typewriter Feet Spacers Original Smashed Rubber Replaced by [[Phoenix Typewriter]]

Squished rubber feet spacers on the Royal standard typewriters can cause interfere with the universal bar and when they do, they'll need replacement.

This is the same sort of interference seen on Olympia SM3s due to their squished/flattened rubber gaskets, though the symptoms are different.

"Phoenix typewriter. Have a Royal day!" <br /> A slightly different sign off from Duane's usual... :)

ROYAL KMM Replacing Type Bar Link Remove Arm Repaired Typewriter by [[Phoenix Typewriter]]

This is roughly what I expected to be the case. I've got to shift the fulcrum pivot wire so I can reattach my Q and @ on a Royal KMG.

Roughly similar to Gerren's video on swapping out typefaces, but with a slightly different technique for speed of doing that. See: https://hypothes.is/a/I_-9rBV2Ee-eMotzy9_Z-Q

I just got a 1950 version of this KMG this week in medium rough shape too. (My 7th Royal and my 2nd Standard)

Mine has some minor carriage issues that I'm hoping clear up with some cleaning. Otherwise it may need some tools and internal repair work and/or parts. If yours is generally working, a good cleaning and oiling should get you going: https://boffosocko.com/2024/08/09/on-colloquial-advice-for-degreasing-cleaning-and-oiling-manual-typewriters/

Manual of the prior model KMM which preceeded it, so the functionalilty should be almost exactly the same: https://site.xavier.edu/polt/typewriters/RoyalKMM.pdf (Royal Standard internals were almost exactly the same from the Ten (1909) through the FP/Empress (1966).)

Home Study Course in Typewriter Repair and Service: ca. 1959, published by the Typewriter Repair School in Little Falls, New Jersey. Focuses on the Royal KMM among others: https://site.xavier.edu/polt/typewriters/homestudycourse.pdf

Searching on YouTube for cleaning and repair advice should help out a lot. Phoenix Typewriter has some solid videos on related models (search also the Royal X (ten), KH, KHM, KMM, KMG, HH, FP, and Empress which are all roughly the same internals with slightly different body styles.)
