This heat sink works perfectly on the lehner motors. I'm using one on my 1930 in my LS10. Although, it really doesnt need it. The lehners run cool. If I ever take the motor out for maintenance I'll probably just take the heat sink off and save the weight.
Heres a link to my LS10 thread if you want to see it installed.
