    belt is correct size, in adjusted the machine to tighten the belt but still have a little play. it sewed for a little and then the hand pulley started tocome off the machine

    If correct size and still slipping it is possible that the machine need to be oiled to reduce overall friction. You can also build up the diameter of the pulley with some tape, or whatever, to make the belt tighter overall.

How to thread the singer 20u33? The tension assembly is new, don't know where the wire is sposed to be...

When you thread the top thread, the thread will drop down on the right side of the tension mechanism and go around the bottom (clockwise) and up the left side. Grab the thread somewhere above the tension mechanism with your right hand and then pull the toward the right (as though you are going to close the circle around the tension disk. The thread should pull on the metal wire (spring) and your thread should pop into the correct position of the tension disk. When you release the thread, the wire spring should pop back to the left. Then you will continue threading through the remaining thread guides and the take-up lever.

Here's a service manual for your machine (in case you need one):

How do I put a new belt on a Singer 99K?

loosen the bolt that holds the motor mount to the machine body and slide the motor up and the belt off. Replace belt with the same length belt and re-tighten motor mount bolt. The belt should not be too tight or it will slip, or generally run poorly.

My moms machine, the belt seems to be slipping. It will sew if you help it by turning the wheel. Will not wind bobbin. How do you adjust belt or replace?

Very possible the belt has stretched so it is slipping. Usually, there is a way of exposing the pulley on the belt. The bolt holding the pulley can be loosened, then pulled to increase tension on the belt, then re-tighten the bolt. You may find more information by searching the information for your make/model machine.

How do you oil the singer xl.1000

please read the instruction menu for oiling area. a small plastic bottle singer oil can be purchased at joanne fabric shop or any department store carries fabric. if you can't find the menu booklet, a drop of oil should be enough on all moving mechanism. don't over do it. best way is move the pulley where the belt is attached. see the movement for all moving mechanism. then one drop oil should be enough. be sure clean out the dust in general are by using vaccum cleaner before lubricating the macjine. do not oil the belt, otherwise will lose friction and slip when sewning. hope this will help. bob

Hi, my brand new 7258 Singer Stylist sewing machine screeches too much. I've cleaned it, oiled (Singer oil) it and changed the needle three times already, following brand instructions. Still screeching too...

Without being able to personally troubleshoot, analyze, and diagnose the screeching, no one is going to be able to solve the problem.

That said, for your understsnding of the gravity of the situation, I provide the following info and warnings!!!!!

Loud screeching like you describe is INDICATIVE OF either a pulley-belt joint slipping at very high speed, OR a BEARING in a high speed application binding, NEITHER OF WHICH IS GOOD!!!!!

To prevent possible total destruction of your machine, I strongly suggest the you unplug it UNTIL you can get it to a QUALIFIED repair TECHNICIAN for troubleshooting.

The symptoms you describe are indicative of a very serious problem which could result in severe damage to your machine!

Hi, This is regarding a Singer sewing machine, model no. 7466. I think the drive belt has slipped off the lower pulley, because the needle bar moves freely when the handwheel is turned toward the...

You probably have to coax it a little at the seams, just don't be too forceful, like try a real thin knife to see if it gives a little on the sides and top. So remember be gentle when trying to get it apart

Sewing machine won't sew fast...very, very slow

Most likely on that model the belt from the motor to the mechanism is worn out or slipping. Usually those can be replaced at home. Refer to your User's Manual for the procedure. Any full service sewing machine center will usually have a replacement belt. Be prepared with your model number to find one. If you are unsure about replacing it yourself then try a dealer I am sure they can help.

Singer industrial sewing machine

It might be the way you're asking that's confusing the problem. It's simple to remove the hand wheel, slip the belt over the track, and then replace the hand wheel. It really depends on the model of your machine - is it by chance a 328K?
