Need to replace the gear in my singer sewing machine model 288

DON'T cut lumps out of your machine. There will be a sequence you use to remove the parts you need to access to the gears more easily. The Youtuber you referred to sounds like they have zero knowledge when it comes to these older style machines.
'Note' Some of the gear mount nuts are on a "Reverse" thread meaning you turn them the 'wrong' way to get them off.
My limited knowledge is more on the much older hand crank and treadle machines.
Try the Youtube link below for a channel called 'Andy Tube'. He has a good reputation for correct repair methods. The link is for a 758 but they're both Touch and Sew machines.
You could also try the Facebook group 'Vintage Singer Sewing Machines' as they have loads of knowledge about loads of different machines.

Replacing all the gears on a Touch and Sew Singer Model 638 sewing machine can be a difficult task and should be done by a qualified technician or a sewing machine repair professional. The process of replacing the gears involves taking apart the entire machine, which can be complex and time-consuming.
The technician will need to have a working knowledge of the internal mechanics of the machine and access to the proper tools and replacement parts. The process also includes adjusting and aligning the gears after replacement, to ensure proper function of the machine.
It's important to note that It could be easier and cheaper to service the machine instead of replacing all the gears, this will depend on the condition of the gears and the technician's assessment.
It's recommended that you take your sewing machine to a professional sewing machine repair shop or a authorized Singer service center to have it checked and repaired if necessary.

You might keep an eye on eBay.

Follow this link, click on the hook gear parts, and you will see a link to a video showing how to install these gears. I was able to follow this video and replace the gears on my old machine. For me it was do-able, but moderately difficult. If you think you're up to it, go for it. Replacing all for gears a t once will cost $50. (Singer 834).
