I am trying to take the back off of the machine. So far, I have
unscrewed about 10 or so screws and there is still resistance coming
from somewhere. I can't see any other screws that need to be taken off.
I am now wondering if this is even possible?

Re: Singer 7444 can't take apart
This is vehemently not recommended. It is almost a guarantee that there is very little that you can do on the inside of the case to repair anything. Leave this one to the professionals. If your machine needs a tune and time, take it in. It's cheaper for you to get it tuned, guaranteed, than it would be for you to replace a machine accidentally damaged beyond repair.

Re: Singer 7444 can't take apart
If this is a modern split casing with two molded parts, front and rear, they are the devil to separate.
Why do you need to break it open ?
There are usually concealed screws inside the cover for the bobbin area and also near the top tension unit......if you gently tease the panels apart it should give some indication of the neighbourhood of the offending screw/s.....they may only need a half turn to relax the pressure on a slot rather than a hole, so will then slide free.........
There are also often plastic clips holding the two sides together in addition to the screws.....nightmare and easily broken
Not for the fainthearted opening split covers, manufacturers love them for cost benefits at manufacture, technicians loathe them when they come to the shop for repair.
What were the symptoms that led you to decide to open the machine, perhaps there is an easier solution ??

the long bit faces the slot by which you pull the bobbin thread
the other end will have a small lip that will fit in the bobbin case near the screw hole
with the screw , it requires only a small turn to make large tension changes on the thread so it is not done up tight
the spring virtually just sits on the bobbin carrier case
There should be a lever (probably black) at the back left side of the machine. When you push down on it (strongly) it should release the whole foot to swing out left from the machine. I think that model has its needle holding screws on the front and you will probably need a small allen wrench / needle wrench to unscrew that small needle screw. I could be wrong. Sometimes they are just a regular needle screw that is unscrewed with a small screw driver.
Unscrew the needle screw and take the old needle out. Try not to drop it into the machine because this can start a whole new set of problems. You can use tweezers or needle nose pliers if it is hard to hold on to it. I think that this model takes a B-64 needle and probably either a 12,14,16,18 size. Use the size that was already in it if you know. If you don't know, you may be able to read it on the top of the old needle (you may need a magnifying glass if it is pretty worn).
Put your new needle into the hole where the old one came out, making sure that the 'eye' of the needle is straight forward or it will not make good stitches. You may already know this, but just in case you don't, the front of the needle is the side that has a groove straight down the front of the needle to the hole so that the thread can run down it to the eye as you sew. If you put the needle in backwards, it will probably not make stitches.
Make sure that the needle is as far up into the hole as it can go and tighten your needle screw. Thread your needle (s) and lay the thread ends towards the back of your machine. Now, make sure that the threads from the loopers are coming directly from the eyes of the loopers, not tangled up with each other and lay those thread ends towards the back of the machine.
Turn the handwheel on the right side of your machine forward until the needles are as high as they are going to go.
Now, push down on the black lever on the back of the machine and swing your foot back into place. Before you try to run it, make sure that the foot is 'locked' in place. You can assure yourself of this, by trying to wiggle the foot from left to right. It should not move from left to right when locked into place. Now turn your handwheel forward again slightly to make sure that your needles are not going to hit the foot. If all is well, run a small piece of fabric through the machine and check the stitch.
Your foot pedal is nothing more than a variable resistance switch, (think dimmer switch) They do get gunked up from use and dust and stuff. Unplug your machine. remove the foot pedal from the machine too... flip it over and look for a build up of threads jammed between the top of the foot pedal and the body of the foot pedal. Remove them. You can also look for and unscrew the screws and open up the foot pedal. (avoid removing/unscrewing wires). See if there is rust, dust, fluff etc that is interfering with action and release of the pedal.
Spray some electronics cleaner in and around the foot pedal area and leave open to dry at least 2 hours. put it back together and give it a try.
If you are timid about attempting this kind of thing or think you may be called away in the middle of looking into your pedal's problem. Take pictures as you take it apart so when you put it back together you have a visual guide.
I just looked up and read the section you are reading. Just to clarify and make sure we are on the same page.
You unscrewed the screw directly behind the head... and attempted to remove the cover on the front of the machine. Sometimes the writers aren't very good at explaining. have you tried sliding the cover up... or tipping it toward you? Be gentle but try different directions of pull until you see the issue or it comes off.
More than likely the motor belt jumped off. Remove 2 bottom torx screws from the base of the machine at the back. Then you have about 7 #10 torx screws to remove from the back cover. Then lift up the pressure foot. The trick to getting the back cover off is to get behind the machine, and slap the back cover and pull off at the same time. Sounds rediculous but thats the way it comes off.
how come tere doesn't seem to be a tray under the machine ? pleasemake sur your machine come with oil pan ( could be come with oil pan ). or maybe your are talked about other model.
please follwo this steeps to change oil for your machine if it come with oil pan:
1 - back head of machine to back said.
2 - you will found oil pan and in right said you can see screw for empty old oil please put any bottel under oil pan and remove that screw until oil is come down .
3 - try to clean oil pan with any dry material and rethight the screw again.
4 - but new oil on oil pan until arrive to high level and turn ON you machine any running it for arround 10 minutes to make oil goes throw all tubes insaid machine.
You have to unscrew the screw for the presser foot first. The walking foot will then fit. Use the same screw to attach the walking foot. Before you insert the screw, take the white handle on the walking foot and slide it on the screw arm for the needle. Now tighten the screw.
If the plate is moving up and down eithetr the teth are set far too high pushing the plate up or the teeth are set too far forward, I would go for the first, if the teeth are coming up well above the slot they are too high, they should be set so that when you look alongside the plate you can just see the top of the teeth, you can adjust the teeth by adjusting the screws underneath the machine where the teeth are.
Could be a few things: 1) the tiny screws that adjust the thread tension may have loosened, or even tightened. 2) the bobbinnitself is not wound well. Place the bobbin in the case, and gentlpull on the thread, if it is too loose, it will cascade out quickly. if too tight, it will give resistance when you tug on it. he little screws on the case will either tighten or loosen the thread tension on the bobbin. Make sure that when you re-engage the case, the bobbin fits al the way into the machine. You should here a little "snap" when it fits all the way in. Also, check to see if the bobbin has too uch thread, making ithard to put all the way in the case.
