How do I reverse directions on a Century M56 motor. Part no. 8-159795-02. Is a diagram available?

The wiring diagram for an A.O. Smith AC motor may vary depending on the specific model and application. However, here are some general steps to reverse the direction of an AC motor:

1. Turn off the power supply to the motor.
2. Locate the motor leads and identify the run winding leads (usually labeled T1 and T2) and the start winding leads (usually labeled T3 and T4).
3. Swap the positions of the T5 and T8 leads.
4. Swap the positions of the T2 and T4 leads.
5. Turn the power supply back on and test the motor. It should now be running in the opposite direction.

It is important to note that reversing the direction of an AC motor may affect its performance and may not be suitable for all applications. If you are unsure about the wiring or the suitability of reversing the motor, it is recommended to consult a qualified electrician or technician.

hi Tristan.
this is what i found.
not sure if its what you are asking.
Which direction does a motor turn? In our simplified diagram, we can say that the wire moving to the left is the equivalent of the motor turning counter-clockwise, and moving right is clockwise. Now, we apply Fleming's left hand rule to determine the direction of the force.30 Dec 2015

Sounds like reverse clutch pack or valve problem

The motor will shift around a bit when shifting gears on the motor. My first suspicion is that the transmission could use a flush and new fluid in it. This would be the most economical first step.
If the problem does not improve after a transmission flush, I would suggest having a reputable mechanic take a peak at the issue.

Hi, see page 6-57 of the owners manual: http://www.extendedgmwarranty.com/owners-manual/buick/1998-Buick-Century.pdf
The tag lamps are on fuse 17. Not sure if the reverse lights are on that same fuse or not, as they are not listed.

call a parts store they usually can provide you the routing for serpantine belts good luck getting it right though it can be tricky pay close attention to how the belt is routed :)

This website shows it has manuals and online diagrams like that. Sometimes a dealer parts guy will run you a copy of a parts diagram. It is a 13 year old vehicle- a salvage yard may have something torn apart that you could see.
