PTO clutch rebuild
Posted: Thu May 24, 2012 9:04 am
I am rebuilding the pto clutch in a LoBoy 185. The manual says there should be a thickness difference of 0.050" between the disengaged and engaged positions and to add spacers to obtain that difference. Without any spacers at all I get about 0.017". When I add any spacers to increase that distance, the friction plates are locked down even in the disengaged position so that the clutch would never disengage.
I am using all new friction plates which are quite a bit thicker than the old ones (which seems normal) but I am puzzled by why they are so tightly held in the disengaged position. The wavy springs are in place as they should be, but is it possible that the wavy springs are not forcing the friction plates apart as they should?
I've rebuilt several of these clutches before but this one has me stumped.
