How To Re-Wire A Potted Motor, Purpose 8: Motor Housing Removal

Now that we’ve got the motor leads disconnected (as shown inward Part 7), nosotros require to take away the motor housing inward lodge to access the motor.

To teach to the motor housing, nosotros get-go require to take away the handwheel. I would unremarkably also disassemble too take away the bobbin winding assembly, but because that is an functioning inward its ain right, I volition salve that for roughly other entry too exit it attached to the motor housing. (Leaving the bobbin winding assembly on is non “standard operating procedure” for me, but every bit long every bit nosotros are careful, nosotros should live fine.)

We start past times loosening the laid screw inward the halt motion wheel:

Don’t receive got it out all the way, only loosen it to the yell for shown inward the photograph below. Leave it inward house to trim the take a opportunity of losing it (I oftentimes run across these missing on Singers I acquire). We exclusively require to loosen it plenty to teach the halt motion cycle off.

Unscrew the silvery halt motion wheel. Unlike the photo, inward reality you’d receive got to role your other paw to concur the handwheel steady, but my other paw is belongings the camera. Remove it carefully, keeping at to the lowest degree iv fingers on it at all times, thence it doesn’t autumn out too chip the enamel on the handwheel (been there, done that).

Next trace the washer out past times pinching i of the protrusions betwixt ii fingernails. If you’re non careful amongst the washer it, too, tin all of a precipitous autumn out too chip the handwheel's enamel.

Now grasp the handwheel firmly too trace towards you. If it doesn’t slide off easily, wiggle it north-south too east-west spell pulling it towards you.

Even amongst former grease sticking it inward place, it should eventually come upwards off amongst only paw pressure. (If it does not, country me inward the comments too I’ll laid upwards roughly other entry showing y'all what to do.)

Now nosotros plough our attending to the handwheel, too a alternative of how to proceed. My preference is to build clean parts every bit they come upwards off of the machine, thence I tin shop them build clean spell I complete the job. I also don’t similar to handgrip muddy parts too and thence fall out electrical stuff. So earlier I teach whatever farther I’m going to give this handwheel, the fiber gear, too the handwheel housing a cursory cleaning. You tin of course of educational activity skip ahead, because we’re on the mesh too I can’t run across you. And if I can’t run across you, I can’t nag you.

To build clean the handwheel’s innards I role these ii implements that I bought for a few bucks at an fine art provide store, I believe they’re used for sculpting clay. (You don't require to purchase these, read on.)

The i on transcend has a flexible metallic tip. The i on the bottom has a silicone tip, here’s a close-up:

I role the metallic i on the metallic parts too the transcend of the gear, scraping the grease off.

The silicone i I role to “squeegee” betwixt the gear teeth.

Every forenoon when I teach my coffee-to-go at the diner, the diner guy gives me a wad of napkins. He in all likelihood thinks I’m going to role them to wipe my oral cavity afterwards drinking the coffee, too he’s wrong.

I could produce a whole entry on how to build clean a handwheel, too i 24-hour interval I will. But I receive got to complete this serial first. In whatever case, I teach the cycle looking similar this:

You don’t receive got to teach it that obsessively clean, but I’d at to the lowest degree teach the mass of the old, hardened grease off of the thing. If y'all don’t desire to purchase the tools I mentioned above, y'all tin in all likelihood respect something inward your kitchen. I wouldn’t recommend toothpicks--you don’t desire splinters inward the gear teeth--but peradventure roughly plastic utensils, or i of those petty plastic swords they pose inward cocktails.

If y'all build clean the dark part, I’d suggest non to role anything other than a moisture Q-tip too a lot of elbow grease. The bobbin winder tire rides on the within of the handwheel, too if there’s anything slippery on it, similar the sewing machine stone oil roughly people role to build clean their machines, the tire volition sideslip too the stone oil volition eventually rot the rubber.

Handwheel finished, instantly nosotros plough to the housing. In this representative it’s pretty filthy; this machine is from 1937 thence the lint is in all likelihood historic.

I take away the lint too pilus amongst a pocket-sized bristle vacuum attachment.

Then I teach at the within amongst the metallic clay tool too burn downwards through roughly to a greater extent than diner napkins.

Afterwards I scrub the insides amongst Q-tips moistened amongst rubbing alcohol. (If y'all teach this route, live careful non to tumble whatever alcohol on the exterior of the machine. Alcohol is fine on bare metal, but it volition swallow through, too ruin, the exterior finish.)

Now it looks a damn sight meliorate than before:

More importantly, amongst all of the excess grease gone, instantly I tin truly run across the ii mounting screws inside.

We require to take away those ii screws. A Brownells flake #360-6 fits perfectly. These ii screws are oftentimes inward in that location REALLY tight, thence I oftentimes stand upwards up too lean my trunk weight into the screwdriver, truly pressing it into the screw, too and thence start out loosening it. To produce this I oftentimes receive got to concur the machine amongst my other hand, but again, my other paw is belongings the camera.

Once the screws receive got been removed, here’s how we’re going to take away the housing. You know how inward the movies, when somebody’s fake-driving too only wiggling the steering cycle dorsum too forth? That’s the motion nosotros need. Do this GENTLY, please, too role both hands. My left paw is on the camera, but should live where the ruddy lines are inward the photograph below. Be careful NOT to pick out take hold of the bobbin winder assembly.

The extremity of the tilting of the housing is exaggerated inward these photos, only to give y'all the idea. Do this every bit gently every bit possible!

As y'all conk on wiggling the housing dorsum too forth similar a steering wheel, trace it towards you. Eventually you’ll experience it loosen too y'all tin slide it off of the shaft. Easy does it.
