Change drive belt


Setting the belt tension on the 707-708-717 machines with the old rubber "Continental" belts:
1. Make sure that the hand-wheel spins freely on the main-shaft bushing stub when the release knob is loosened.
2. Assuming that you are using the original 441mm "Continental" rubber v-belts, the setting is made by means of loosening a 5mm Allen socket cap screw at the base of the step pulley support.
_____________
NOTE: The hand-wheel, stepped pulley, and motor pulley v-grooves must be clean. This is to say, that they cannot have any particulate or threads wrapped around the grooves.
4. The pulley will be automatically pre-tensioned to a 7 o'clock position by means of a spring to maintain the stepped pulley position. By pulling the belt toward this 7 o'clock position, the pulley tension can be adjusted and then tightened by means of the fixing screw.
_____________
5. It is important to know that both the upper and lower belt tensions can be independently adjusted so as to allow the hand-wheel to spin freely for bobbin winding without having the hand-wheel drive the machine. This is done by adjusting the step pulley support + or - radially, near the 7 o'clock position.
If the hand-wheel drives the machine with the upper belt loosened, then either the belt is too tight or the hand-wheel bushing and main-shaft stub need cleaning and lubrication.
Note: Lubrication was once the standard factory procedure with a class 68 oil, but experience dictates a dry lubrication with graphite. Silicone lubes are not recommended.
6. Do not over-tighten the 5mm Allen fixing screw as the 5mm threaded frame boss can be broken off.
================
Adjusting with the original Polyurethane v-belts on models 807-801-810-817-811 machines:
1. Follow the same procedure as mentioned but allow the step pulley's positioning spring provide the belt tension. Nothing more is required here.
NOTE: Sometimes these belts and pulleys get oily thus allowing much slippage. A simple cleaning of the belts and pulleys with mineral spirits can solve this problem.
================
After-market belts:
NOTE: One can find after market belts that serves to drive these machines but not without some problems as they are usually wider belts and don't fit the pulleys well. In this case some adjustment will be necessary.

Brother Sewing Embroidery Machine


I agree with sylviaivie about find another repairman, they are suppose
to guarantee the work they do.
when the upper shaft is replaced & then the machine is retimed
the machine should work just fine.
but just don't take it back to that man to be repaired
here is a tip if it happens again,,
always try to cut the top thread first,
& turn the machine up on it's back to access the bottom cover
take the cover off the bottom to get access to the bobbin thread
where you can cut the bobbin thread
then you should be able to get the needle out without breaking it &
damaging the upper shaft, replace the needle & make sure
that the thread is good quality & not knotty, clean out the bobbin area of lint or thread
always change the needle on the embroidery machine every project
make sure the bobbin area is kept clean of lint or thread
clean under the needle plate at least once a week for lint if you
embroidery everyday or just often

Brother pe-770 f05 speed sensor error - How to fix?


F05 error, speed sensor. I fixed successfully 2 of those. Speed sensor is located on a small board, under a protective plastic, located over the main front board. Remove front panel and bobin winder assembly. Remove the 2 screws of the small board. Remve CAREFULLY the small bord. Under, on the main shaft, are located the needle positionning sensors and the wheel of the speed sensor (left wheel on the shaft). The speed sensor is located on the board itself, it's very small. Clean carefully both the wheel and the sensor with Q-Tips and alchool, reassemble the whole thing and it should restart.
While U are there, take a thin nozzle oiler and lubrificate all the suppots of upper and lower shaft, all the needle bar mechanism and rotary hook central shaft and gears WITH VERY THICK oil. Needle bas assembly is the most critical point. I have 14 of those machines, almost all of those seized there before I learn how to lubrificate it. Also seized on the bottom shaft and on rotary hook pin

E6 message on brother CS 6000i


Needle Position Sensor is disconnected
This sensor detects the drive timing for the pulse motor for
zigzagging and feed, the vertical stop position for the needle. It
detects the upper shaft angle of rotation using a shutter attached
to the upper shaft and an optical sensor.

My Husqvarna Viking Emerald 183 has always had a problem with the needle up needle down button - after pressing it once, it often sews anywhere from 3 to 20 stitches. More recently, the machine keeps...


There is a sensor on the upper shaft that recognizes the position that the machine is in. A small disk on the upper shaft that has sections removed from it will block the sensor trough some range of operation and not at other times.I have never seen this in a 183, but you may have a sensor that is misaligned so that it doesn't completely block or clear the beam of light.It will need to go to an authorized repair center for repair. Some of these parts are very delicate. Don't risk damaging something working on it yourself.

Needle stop switch will not control needle stop position


I can tell you its always on the upper shaft in the kenmore and it's on the right by the handwheel. The shaft has a wheel that rides through the sensor for shaft position sensing. It can actually go bad. If your machine zigzags ok, its not the shaft sensor becuse it knows where the shaft is to z.z. so it could be jsut that function on the board. Ive seen that.

Janome Excel 5124 reverse lever


If you pull the bottom off the machine (half a dozen screws) there is a cam on the main drive shaft. The cam is probably jammed in the reverse position due to lack of lubrication on the shaft. You can move the cam back manually and it will operate in forward direction. It appears that the shaft needs lubrication.
