Title: American threads on a rotary topper .
Post by: cloddopper on July 04, 2016, 12:55:07 am
Has anyone got a towed wheeled American topper that has a Briggs & Stratton engine on it , using a single belt to drive a 24 " cutting disc that has two  12" centrifugal cutting blades on it .

 My pal ha one and the disc has come free , fell off
 On looking at it underneath the cowl I see that the 3/4 UNF keyed shaft on which the cutting disc was fixed ( castellated nut & split pin C/W big thick flat washer )  has been opened up so the keyway is almost a " Vee " shape .
 
 I'm looking for someone who has removed the drive shaft  ,for I would like to know if the bearing on the shaft is a wobbling knuckle arrangement or if they are sturdy fixed ones .
I'd also like to know if they had any great difficulties with the drive belt pulley ,  such as it bending out of shape if I use a home made wide lipped puller on it
 I'm hoping to make a new shaft for on my metal work lathe
