Try and get inside and mop up excess oil - then do not add oil for a month or 2. when you next add oil just 1 drop on each moving part is all that is required.

ther is no oil reservoir in a domestic sewing machine so the oil you see is what has been added recently.

The flywheel on my elna su will not turn

either a jam up in the bobbin which is preventing the needle bar from coming up, internally siezed up, or the friction belt internally to the flywheel has broken/worn out.

There are a couple of different SU models, the Star Series and the Air Electronics both had an SU (supermatic) model so I'll be general in my description. Firstly remove the needle cover plate and check around the bobbin race for jam ups. Or if the machine has been packed away for a long time unused, then we could assume this is a sieze up. FIRST REMOVE THE POWER PLUG FROM THE MACHINE FOR SAFETY. You'll need to remove the top machine cover and delve into the insides with a bit of patience, good quality sewing machine oil (tri-flow is perfect if you can obtain some, bike shops have it or I got mine from Ebay) and Qtips or something similar.

There should be a couple of screws holding the top cover onto the machine so remove these and then lift and tilt the cover to the back around the lifting handle and making sure you clear the bobbin winder mechanism on the right. Really good idea to take photos with your mobile as you go so you can remember where things went. Now apply triflow to the metal moving parts you can access, in particular the top of the Elnagraph shaft which should have a red mark for oiling point, and the needle bar swing bearing. Keep oil away from the belt/s on the right side of the machine where the flywheel is driven by the motor.

You'll need to carefully clean, oil and gently move the flywheel back and forwards until things free up.

Baby lock bl4-736d won't stitch--It has not been used in about 6 years. It worked fine the last time it was used. I don't know where to oil or even if that is the problem.

If your machine has not been used in six years then it could have siezed up. If there is a threading up diagram inside the front looper cover then it may show the red oiling dots too. These are usually on the upper and lower loopers where they move through another metal part. And sometimes a red spot at the back of the stitching platform to oil internally.

But firstly, can you turn the flywheel manually towards you? Does the loopers and needles move through a stitch sequence when you do? If there is no movement and the flywheel is turning then probably a gear has failed in the main drive shaft, many machines have nylon gears now to lessen need for lubrication but the gear itself may split as it ages. Can be replaced but usually means dismantling most of the machine to do so. Definitely something for the BL technician though.

If you can move the flywheel and things are moving then I'd suggest you oil all the metal moving parts, rub some oil onto both blades and give everything a good clean out. Then manually turn it through stitch sequence several times to spread the oil, then plug it in and see if the machine will now run. Just take it slow and gentle. Then change the needles and thread it up and see if you can get it to chain off.

Hope this helps.

My ELNA 3005 machine is making graunching noises

Open your side cover. normally a screw on top and two on the bottom and maybe one on the side.
After removing the cover you will see one or two tensioner plastic black pullies.(they keep your motor belt and timing belt tight. They need a little bit of machine oil.

Kenmore sewing machine mod 1703 motor runs but

By 'The wheel the belt is on' you mean the motor pully? If that is so obviously some oil has some how made way on the pully and the belt. Try to remove the belt and clean both wheels and the belt free of oil. This shd slove the problem.

If it doest then please send a photo of the arrangement showing pully and belt. U didnt mention if the machine is old or new. Did u oil it recently before trouble developed?

Problem with 40 old Elna Zigzag , V/NV/21, Type: 21cF347986

Um, sounds like the machine has seized from old, dry oil and it is dragging down the motor. Avoid using the machine until the issue is resolved so the motor is not damaged.

Depends what kind of oil & grease your husband used, as it could have complicated matters. Also, if the machine has been neglected for a long time, combining heat in the clean-up/lube process is sometimes very helpful. (Can't tell you the machines I've picked up that have had motor oil and grease applied!!! The old gunk needs to be cleaned out and then the appropriate lube applied.) Most machines do not use grease unless it is white lithium grease--perhaps on cams. Oil needs to be fresh, good quality sewing machine oil. I prefer liquid Tri-Flow Synthetic Lube from the hardware store. Do NOT use WD-40, 3-in-1, cooking oil, motor oil, etc. on your machine!

Wheel on right side that controls the needle up and down is very tight...
