I got the drum brake end off the big forklift motor.

After removing the brake, I could see that the shaft going through the brake drum is threaded on the end with a castellated nut, and after that it IS SPLINED!

The splines are the same as on the main drive shaft end.
That means that perhaps I can use the brake drum cover part with the splined hole on the main end of the motor and use it as a base for a coupler.

It may even be possible to use it as a base to attach the flywheel and then keep the clutch in the system.

The downside is the brushes are terribly worn, and the commutator doesn't look great.

Once I get the motor further apart, I can get a better look at it, clean it up some more, and make sure it's the way I want to go.

I hooked up my 12V jump starter and made it spin, but I could see a little bit of arcing at one of the brushes.

One thing about the hydraulic pump motor is that it is in new condition (totally rebuilt) and has awesome brushes!!! Too bad it has such a lame connection.
