I really must "thin the heard" as it is called. I have a 301 Mocha Long Bed. I don't need a Short Bed, too. So this one is elected. The hook had a burr on it so I switched the hook from my LBOW to this one. It sews very smoothly and the motor is fine. I featured this machine on an earlier post http://mysewingmachineobsession.blogspot.com/2011/11/train-whistle.html.
I cleaned the old grease off of the gears. I used Tri-Flow grease as the lubricant. It works very well and doesn't spray all over. It Sticks.
I cleaned the textolite gear on the handwheel. I used NO SOLVENTS on this gear. It is a fibre gear and I did not want anything to absorb into its 60 plus year innards. I wiped it wipe a cloth and the, using a pick from a nut cracker set, scraped the old grease out of each crevice VERY GENTLY.
I pulled the motor and cleaned the worm too. I admit, I did not scrub the inside of the machine here. Ray claims that is for cosmetic purposes only. I agree.
I was just cruising eBay (I can't help it) there is a 301 someone is trying to sell as "pristine" with black gunk all over the gears. YECH. I prefer gears with metal showing and just a hint of moisture from the Tri Flow.
I hate to see it go, but go it must. Such is the way of the sewing machine fanatic. Until I become a hoarder, some of them just have to come for a bit, get cleaned up and stitching and then move on.
