Keyless Bushing
In May 2008 we changed the shaft mounting to use a Fenner Trantorque. This mount replaces the collar and nut arrangement used since January 2008. The trantorque is concentric to 0.001 which produces a much more concentric mounting for the bowl and a much smoother rotor. These images outline the mounting. The trantorque instructions state to tighten to 200 foot pounds. In this application you only need to tighten snuggly. If you over tighten you risk deforming the aluminum hub.
This is the ideal mounting. This o-ring helps hold the trantorque in place with assembling. If you need more space under the bowl, you can optionally raise everything up to 0.25 inch.

Bushing from the top. Bushing from the bottom. Trantorque now sits on a small internal shoulder.
Bushing from the top. Bushing from the bottom. Trantorque now sits on a small internal shoulder.
This is the bottom side. Note the small internal shoulder that prevents the trantorque from falling through during assembly. Also shown is the new enlarged sling lip. This creates an air gap seal that works very well and never wears out. This cone with an o-ring seal prevents oil from coming into contact with the trantorque and shaft. The nut size is matched to the trantorque so only one wrench is needed. This is the cone from the top side.

This is the proper installation of the trantorque. This is the cone installed. It should be installed snug being careful not to over tighten it.
