When you are sitting at the machine, like you are when using it, there is a tension regulator lever on the front left side of the machine. The plate is numbered from 1 to 4. It says Loose at the top and tight at the bottom. Hope this helps.
Under the cabinet there is an arm that you your knee to push on.
To adjust the lower tension on an oscillating hook type machine you would turn a screw on the inside of the machine. You want to locate the bobbin tension screw and turn it 1/4 of a turn to the left.
Adjust the bobbin screw. Also, check if it is broken.
Your tension is too tight. To adjust your tension, thread your machine and sew a test piece. It should be perfectly even within the test piece. If the threads are not centered, adjust your tension wheel and re sew until the threads align. See your owner's manual for instructions.
The alternator is rotated on it's pivot to adjust belt tension.
Apply a wrench to the center bolt on the pully and turn it will adjust the tension.
you dont adjust a tension pulley you adjust the position of the compressor to tighten the belt
You might want to check the belt or the clutch if it is a GE. The V-belt is probably slipping on the pulley. If there is no tension spring or place to adjust the tension, try belt dressing or replace the belt.
No
Adjust it.
Loosen the alternator tensioner bolt. You will be able to slide the alternator either way to adjust the tension on the belt.
There is no adjustment of the pump. You can adjust belt tension, by loosing and adjusting tension with the bolts holding it in place, but that is all.
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
