Physical Therapy for the SM9

My three dollar honey has arthritis!

After some investigation as to why the keys and typebars were frozen in place, I discovered that there was a great deal of sticky, oozy goo all over the typebar rest.  I’m guessing it is adhesive for the typebar rest that became very warm in storage and began to drip.  Downward.  Onto that segment area wherein the keys are supposed to enact the typebars. Apologies if I’m using the incorrect nomenclature for some of the parts – fellow insurgents, feel free to correct me!

I now find myself administering some gentle physical therapy to my poor 52 year old SM9’s typebars. “A little degreaser, now lift, now drop, now lift…”.

Aside from that, all other aspects of the machine are sound.  Looking forward to a full recovery for this contemporary of mine!  ~TH~

  1. I recently worked on an SM7 with a similar goo problem – sticky molasses-colored gunk on the typebar rest that seeped down the typebars into the segment causing sticky keys. The keys of the outer segment were especially bad. I used carb cleaner and had to do repeated cleaning as the keys would free up and then get stuck again overnight. I read on another typewriter blog that industrial-strength Zep, a degreaser, is effective for dissolving the goo.

    • Excellent, yes, just so! Identical issues to what you outline. I have subsequently run into another issue with the critter, the drawband appears to have come released – and it’s now partially off the spool and jamming the carriage. Looks like I’m taking the critter apart a little more. Good practice for me though. — Thanks SO MUCH for your help. ~Tom~

  2. I was doing this exact same “therapy” with my SM9, today–and now my kitchen reeks of PB Blaster, and so does the machine. What solvent did you use?

    • I used GUNK Engine Degreaser (original) because I have it on hand. Don’t know if the smell lingers any more or less than PB Blaster – should definitely use any of this stuff in a well ventilated area. I work outside when I can. Good luck on the Olympia! ~T~
