Hi all,
I've noticed on my new (to me) B&S 618 that the spindle will slow considerably during a relatively heavier cut. I pulled the back cover off and noticed the motor mounting was a bit suspect (photo below). Maybe the original owner used some longer belts or attempted to accommodate for worn belts? Does anyone know of a different spacing used in the drive mounting setup other than what is shown in the manual (photo below as well)? I know it wouldn't look like this but want to confirm that I'm not missing a spacer between the motor clamp bracket and the motor mount plate.
I've ordered new #431 o-rings for the drive (please correct me here but I pulled this size info from another PM post: http://www.practicalmachinist.com/v...wn-sharpe-618-micromaster-useful-info-317978/). To replace the o-ring belts is the recommended procedure to remove the spindle or the motor (I will probably have to remove the motor anyway to fix the spacer issue but good info for others)? Spindle seems a bit less fussy just due to weight but wanted to hear from others who have done the swap. Thanks!
