Sachs Torpedo 3 speed hub, locks up

Posted this in the Mechanics forum, but no hits.

Have a bike that has a Sachs Torpedo 3 speed coaster brake hub.
Shifts and brakes ok. But,if the roll the bike backwards a foot or so, the hub binds up and locks.
To unlock you have to work the wheel forward and back.

Ideas of cause and what is needed to fix?

Thanks

Answer my own question, for others future reference.

Turns out that there are 2 sets of pawls in the hub. Those on the non drive end of the hub were sticking .
Clean and degrease makes all everything work like a dream.
