I am curious to know the diameter of the crank snout on b-series motors. Most d-series crank snouts are 24mm diameter, some of the older ones (88) are 22mm. The reason I am interested is because Fluidamper and ATI don't make dampers for d-series motors, so I am interested in possibly adapting one from a b-series. Could someone measure the ID of the crank pulley or the OD of the crank snout on their b-series motor? thanks.

 

26.97mm

 

thanks alot man. So I guess my idea wouldn't work without welding material on. I was hoping it was the other way around (d-series larger crank snout than b-series)-so all that would've been needed was opening up the hole on the damper. Oh well.

 

yea, the b-series is definitely bigger. i think my measurement is off, but it is def. bigger than an inch.
