Vintage new home (XR-VII model 990)sewing machine with a handwheel problem
Hi there, my vintage machine has a handwheel that is soooo hard to move. I can move it though and the rest of the machine seems to move properly although very slowly. there is a gear connected to the wheel that can move freely when I move the belt clockwise but when I try to move it/them counterclockwise it very difficult. I have tried to oil, clean etc. and have removed the outer casing to the machine. any ideas? when I plug in the machine the motor seems to want to run but the wheel is so hard to move that it can't.

Re: vintage new home (XR-VII model 990)sewing machine...
Can you post a photo of the machine, cannot find a reference to this model.
1st just check around the bobbin case area for jammed thread, also in/around the *takeup lever (up/down arm) mechanism near needlebar, as thread often gets wound around and jams the shaft
If it really seems like corrosion in an elderly & neglected machine.... disconnect from power, and using a small rocking movement of the handwheel to identify the parts that should move and with all the covers removed and in a dry well ventilated area with old newspaper to absorb excess,
.......give a light spray of WD40 or similar penetraing lubricant on horizontal Top shaft at each end where it joins main body
..... the region that operates the *take up lever cranks and counterbalance
.....the handwheel has a clutch mechanism, so if you can undo the wheel to access this, it may well be dry and need lube.
.....In the base is another horizontal shaft lube each end and a little where the gears meet to change the drive direction under the hook race/bobbin.
With the same gentle rocking motion of handwheel, see if there is any improvement ...but do not force anything......(to stitch forward, the handwheel spins "over the falls" toward you)
You may not see immediate improvement, so leave overnight and be patient, it may take several days........just be very sure there is nothing jammed anywhere.

It sounds like you have a broken drive gear. Most of the gears in a sewing machine are no longer made of metal, they made of hard plastic. They WILL break after time due to the stress put on them when sewing thicker material. If you have a very expensive machine, you might want to have it repaired. If your machine is on the cheaper side, you might want to look around for a replacement. Sources like EBay and Craigslist are a good place to start looking. Local yard sales are also often helpful.
Most likely the machine has seized due to lack of regular cleaning and oiling. Take it to a sewing repair shop for a maintenance check. (Avoid running the machine while the motor is unable to move the parts properly. It could damage the motor.)
Check that the stitch length is set to make ~10 stitches per inch. This stitch is long enough to actually move the fabric. If the stitch length is set too short, the fabric will stay barely move and the needle will stitch almost in place.
Check that the feed dogs have not been dropped for darning or free motion quilting. In this position, they do not rise and are, therefore, unable to contact the fabric to pull it through the machine.
With the presser foot raised and using no fabric, hand rotate the handwheel and watch if the feed dogs actually drop down below the needle plate, move toward the front of the machine, then rise above the needle plate, and move toward the back of the machine. If the feed dogs are moving in this manner, then they are functioning properly.
Is there lint or gunk stuck in the feed dogs? This will restrict the ability of the feed dogs to grip the fabric.
Are the feed dogs worn? Are the little teeth worn so there are no sharp points?
What type fabric are you using? If it is very light-weight or slick fabric, the feed dogs will have a difficult time gripping the fabric. Most machines have a presser foot pressure adjustment so that more pressure is applied between the presser foot and the feed dogs. Consult your Owner's Manual. The adjustment is usually a dial either on the left side of the machine, on the front of the machine located above the needle bar, or on vintage machines it is usually a skrew located under the top lid above the needle bar.
Try installing a brand new needle. A bent needle sometimes will not connect properly. Be sure that both upper and bobbin threads are threaded correctly.
On the other hand, the needle/hook could be out of time. You can check that by hand turning the handwheel and watching the needle/hook movement. There are a multitude of web sites and videos that discuss timing. Or--check with a sewing machine technician.
Hi Thi: make sure the machine is not set to wind the bobbin. Turn the handwheel towards you and see if the needle moves. You may have a belt that has come off. Does the machine make noise like the motor is running when you press the foot control?
if the sewing machine repair shop knew the machine needed a clutch adjustment, then why didn't they fix it. or if they said they did & it's not fixed, I'd call them & ask them why the machine is still doing the same as it did?
my suggestion is that the machine needs to be serviced at a sewing machine shop, because for 1.it's not responding 2. it used & you don't know when the last time it was serviced 3.something is wrong with the machine. hopefully there are no broken parts, but having the machine serviced will tell that. as for a manual
