Knucklehead Engine Case Set
Oil from top end returns through pushrod tubes. Does not return through cylinder base. Case accepts loose roller bearings on the sprocket and pinion shaft side. Case set is designed for replacement of the original cases. No serial numbers are provided with these case sets. A Bill of Sale will be issued for blank cases. Case set includes pinion and sprocket shaft races. Use 2 gaskets when mounting the oil pump body for proper clearance. **NOTE: Numeral inch7 inch stamped on rear motor mount halves to denote 74 cubic inch. Builder may stamp these numbers in.
Tech Notes: *NOTE: To confirm the main bearing fitment clearance you must take the standard bearing measurement and multiply it by 2 then add that answer to the left side sprocket shaft meaurement. For example the standard bearing measures .250 multiplied by 2 equals .500. The left side sprocket shaft measures 1.000 adding them together you get 1.500 which means you're running 1.501 fitment with .001 clearance.
