Hello MMD,  I am in the middle of rebuilding my first wind-motor
and I am trying not too make too much of a mess.  I just have one
quick question for you all:  Is it absolutely necessary to replace
the bellows cloth on the wind motor slide valves?

Thanks!
Joel Gauthier

 [ Since the cloth doesn't flex you could defer that task 'til the
 [ next rebuild.  If you think the cloth leaks then apply a sealant.
