7t puller timing?
 

I picked up a 7t puller from a buddy and he said the timing had been messed with and the motor gets quite hot.I do not see any ''marks'' on the can as a reference point to go from.I would like to put this back to ''stock'' timing and go from there.Any info would be much appreciated,thanks.I also posted this ? in the puller section on Holmes thread.See what one works.

Per John's post here.

Timing

Now, on to timing your Cobalt Puller.

Amp draw method-- Loosen the endbell and put low voltage to the motor with no load (3v is easy to work with if you have it), rotate the endbell just a bit back and forth until the amp draw is lowest. Retighten.

If you put the voltage to the motor in the polarity that you will use it, it will be most accurate.

The brushes line up with the Screws on the endbell. At neutral timing the brushes will be between the magnetic north and south. You can visually line up the brushes, or you can use an ampmeter to help. At Zero timing the motor will draw the lowest amperage. NEVER run the motor with retarded timing, as the brush will throw sparks and eat the comm quickly.
1. Screw on the endbell slowly being sure to not damage the threads.
2. Use a bit of plastic or wood to seat the brushes onto the comm (I use a sharpened chopstick). If you use metal it will damage the brush and comm.
3. Screw the endbell down until the armature does not wiggle in the motor case, then back it off 1/4 to 1/2 turn until the brushes line up.
4. Tighten down the endbell screws (blue loctite will help keep them tight) being careful not to change the timing. The endbell screws on a Cobalt Puller take a 2mm allen wrench.
5. If the motor rotates the wrong direction either swap the motor leads or rotate the endbell 180*.

Now bolt that motor in and beat the snot out of your rig!!
Any Questions, post em up!
