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.
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.
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

yes,it's worth the money to replace the feet,, & buying a new or used sewing machine as a back up is good too
this type of problem related to "overload protection" the motor can't overcome the load work,then it would able to stop your machine,theres problem on motor assembly try to check the carbon brush.if worn out replace,handwheel are couple to motor pulley inside machine.there an opening for the belt.if you want to check it loosen bolt cover,have move the belt you can figure why handwheel moving tight.if you realease the belt handwheel will move independently but handwheel is connected to a cam shaft w/mechanical link connected such as gears,cam and bushing that
can also suspiciuos of obstruction can came there.take this to service center if trouble link to mechanical problem.have a nice day
rate me and thank's
There is cluch on the handwheel that connect motion,try to tighen this If negative,There are two small bevel gear (hard PVC )connecting to the upper crankshaft where the handwheel was connected.This transmit motion when motor run, most commonly the vertical rod where one bevel gear was connected maybe broken or viceversa at the upper crankshafting that holding the bevel drive gear is broken try to check this.
