How To Change Belt On Sears Kenmore Sewing Machine 158.18033

Someone asked me today on how to practise this and so this tutorial covers the motor chugalug replacement on the bulk of Kenmore 158 series sewing machines. Information technology does non utilize to the 158.1030 or 158.1040 sewing machines because the motor attaches differently. Depending on the model of your automobile, you may or may not need to remove the balance wheel or a bottom cover, but the steps to loosen and supervene upon the chugalug are essentially the aforementioned across the board.

The car hither is a 158.1430, merely as I said, the process is direct forrard and applicable to nearly Kenmore machines and then I will explicate it in steps. If your Kenmore has a bottom embrace (convertible or free arm machine) you will need to remove information technology starting time before proceeding thru these steps.

Step 1. Remove the top comprehend of the motorcar. At that place are no screws holding the lid on and it is held with spring clips… simply pop the cover off.

• 

• 

  Maybe yous noticed, but please Ignore the fact that the belt is already off the pulley on this machine…

Step two. Remove the two screws attaching the rear cover to the machine.

Step 3. Tip the machine up on its olfactory organ.

Pace four. Loosen the screw in the residuum wheel terminate move knob (but don't remove it). Unscrew the stop motility knob and remove the large washer from underneath it.

Pace 5. Looking at the bottom of the machine, loosen the bolt on the motor bracket with a large screwdriver, 12mm wrench, or a crescent wrench. This bolt may be very tight. Shift the motor bracket up as far every bit it will go to loosen the belt and remove the belt from the motor pulley.

• 

• 

Step half dozen. With the belt removed from the pulley, gently pull the remainder wheel and the rear encompass away from the elevation of the machine and away from the upper arm shaft bushing. The rear cover has clips on the bottom that undo when the comprehend is pulled away from the acme of the encompass. The motor belt is captured between the balance wheel and the cover. Every bit soon every bit the residual wheel is free from the sewing arm shaft bushing, remove the belt from between the balance wheel and the embrace.

• 

Step seven. Remove both belts from the large double caster found behind the rear cover. This pulley is actually a reduction pulley and information technology magnifies the motor's power to the sewing mechanisms… a nice characteristic!

• 

Step viii. Catch your new belts. You will observe that they come in a gear up and there are two sizes.

• 

The smaller belt goes on first. Install the small chugalug on the big caster groove and the motor pulley. Next, put the longer belt on the smaller pulley and lay it over the upper arm shaft bushing. Replacement motor belts are readily available and can exist plant at any online sewing automobile parts store. They are usually sold in sets and you should replace both.

Step 9. With the balance wheel inserted thru the hole in the rear cover, engage the rear embrace bottom clips and guiding the balance wheel towards the upper arm shaft bushing, guide the chugalug back on the groove in the balance bike. Keeping some tension on the belt, put the balance wheel on the bushing.

• 

Pace 10. Arrange the tension on the motor chugalug past pulling the motor subclass down so the chugalug is snug. It does not need to be tight but it should not be loose… Just snug. Keeping the motor bracket snug against the belt, retighten the motor bracket commodities.

Stride eleven. Replace the big washer and the remainder wheel stop movement knob on the machine with the wings pointing out and engaged in the slots on the sewing arm bushing. Screw on the finish motion knob and tighten the minor screw.

Tip of the mean solar day… Because the big washer has ii "wings", it tin be put on in the wrong management. If afterwards tightening the modest spiral the stop motion knob does non loosen plenty or at all (as in what you would do to current of air a bobbin), loosen the small screw, remove the terminate motion knob, rotate the large washer 180 degrees and put it back together. You lot would think there is a fifty/50 alter of getting it right the first time, but somehow I normally become it incorrect lxxx% of the time (go effigy…).

Step 12. Set the machine upright and reinstall the two pocket-sized screw that concur the rear comprehend on. Don't brand them too tight or they tin can crack the plastic embrace.

Step xiii. Supercede the top cover and snap it into place.

Stride 14. Exam the motorcar out to make certain the belt does non sideslip… snug it a little tighter if it does.

That'southward it! Pace 14 is really self explanatory, but stopping at xiii steps in a tutorial is bad luck… I only threw footstep xiv in in that location to avoid whatsoever calamity this may cause (just kidding…) Anyway, that's all there is to information technology!

First and foremost, I decided to share some of my experiences with vintage all metal sewing machines. Information technology is a natural progression of my life feel exercising my hands and my mind.

At the same time, I married a wonderful girl and started a new life. Graduating College with a degree in Structural Engineering, I began a 35 yr career in the Federal Regime. Along the mode, we were blessed with 3 cute children. Earning a Masters caste in Engineering and registration as a Professional person Engineer I worked for the do good of my family and my Country. Over the years, I have pursued many different hobbies... woodworking, car mechanics, astronomy, and taking apart and putting together all sorts of things.

Her interests take ever been in sync with mine, merely spending so much gratis fourth dimension with her, I realized how wide her talents are! One involvement she is particularly fond of is sewing. It didn't take me long to put 2+ii together and realize that I could do something with this. So, acquiring, adjusting, servicing, and restoring sewing machines was a win-win. I have a hobby that is detailed, involves tinkering with precision engineered high quality manufactured machines, while she has an opportunity to run up on various unlike makes and models of sewing machines. While in that location are many that have data on line, and what I have to say more than likely has already been said, I wanted to contribute to that chat and learning gleaned from my experience and research.
