We've removed the bobbin illustration in the concluding entry, revealing the bare claw assembly beneath. As you lot tin run across inwards the photo, the expanse underneath the claw assembly is filthy. We've got the bobbin illustration off, thence nosotros powerfulness every bit good take the claw assembly to construct clean downwards there. We entirely bespeak to take 1 screw, that big 1 inwards the center.
This screw is a rare illustration where a B-Square flake (#10 3/8) fits perfectly, together with a Brownells flake (#360-4) is workable but non a perfect fit. If you lot receive got the Chapman screwdriver set, the flake labeled "98" is too precisely a passable fit, non perfect. (UPDATE: On 1 of my 201s, I institute the Chapman "97" flake stand upward for amend than the "98," although both machines receive got screws amongst slots that appear identical to the naked eye. Test both bits first--stick them inwards the slot past times themselves together with wiggle them loosely--to run across which is a amend stand upward for before you lot begin to take the screw.)
Click here to read an before post most these screwdriver sets, together with click here if you lot bespeak to lodge the Brownells bit.
Please banking concern annotation that the Chapman flake numbers are read amongst the blade pointing to the left. In other words, this is a "98," non an "86:"

| Try the Chapman "98" flake every bit good every bit the "97" to run across which fits better. |
If you lot purpose the Brownells or Chapman bits for this screw, hold upward certain the blade is perfectly centered inwards the screw. With these two, the blades are non quite broad plenty to accept upward the entire screw slot, thence if the blade is non centered, it is possible you lot volition strip the screw.
For novel wrenchers, removing this screw tin hold upward a trivial tricky for 2 reasons:
1) The machine's arm volition hold upward slightly inwards the way, forcing the screwdriver into an angle, which increases chances of strippage. If you're clumsy or non nevertheless confident amongst your screwdriver skills, I'd recommend using a screwdriver ratchet (you tin acquire most them inwards this post).
2) The residual bicycle needs to hold upward held inwards house spell you lot loosen the screw, or the claw assembly volition precisely plough amongst the screwdriver. If you lot bespeak both hands on the screwdriver, receive got individual concur the residual bicycle for you.
Remember this slice of screwdriver advice: Once you've got the flake going lead into the screw--not an an angle--press downwards quite hard, every bit if trying to force the flake correct through the screw. Only thence should you lot begin turning the driver, thence that it doesn't skid out. (If you're clumsy, receive got individual else concur the residual wheel, thence purpose 2 hands on the screwdriver--one upward top on the handle, pressing down, together with the other mitt belongings the flake thence that it doesn't skid out of the screw.)
It's non a long screw together with comes out pretty quick.

| Nice affair most magnetic bits: They force the screw upward amongst them. |
It volition in all likelihood hold upward slightly stuck together with volition non come upward correct off. Wiggle it gently dorsum together with forth--like a see-saw, non a steering wheel--and it volition loosen itself plenty for you lot to easily force it off.
Now you lot tin construct clean out all this nasty crud.
I similar to purpose Q-tips dipped inwards rubbing alcohol. Be careful non to drip onto the bed of the machine, the alcohol is non expert for the pigment job.
The argue I purpose alcohol hither is because it breaks upward erstwhile crude together with grease, together with it evaporates completely, leaving no residue. I wouldn't purpose sewing machine crude to construct clean hither because it leaves a mucilaginous residue, which volition speedily attract to a greater extent than lint together with dust.
Once you've got it dainty together with clean, precisely popular the claw assembly dorsum on. There's a trivial positioning pivot on top of the mounting shaft, thence there's entirely 1 means to seat this dorsum on. Replace the screw, tighten it up, together with you're done.
