Reproduction crankcases which meet or exceed highest restoration demands. Cast from state-of-the-art materials and machined on CNC equipment for strength and precise fitment. Intended to work with stock or identically constructed engine components. Finished and detailed like the original counterparts so these cases will smoothly blend into your old mill to give it a new life. For ease of installation both case halves are carefully matched and feature pre-installed case bushings, which are line bored and lapped for standard rollers. Cam bushings are already in place and reamed. (For exact measures pls see facts).
All cases feature laser-engraved CB production numbers, which are registered and filed.

Quality information re. Cannonball Crankcases.
The W&W Cycles AG selection of Cannonball engine cases are not related in any way in terms of manufacture or distribution to the products of Motortechnic mfg (distributed in the USA by V-Twin mfg/Tedd Cycle Inc., among others).
We have been working for years with three German companies selected by us, who carry out the casting and machining, including the fitting and honing of the bearing races for the crankshaft.
For this reason we grant our own manufacturer's warranty for Cannonball products.

Truett & Osborn Flywheels
They are made just like the stock counterparts, i.e. the left wheel is thicker than the right one (exc. JD and 45”), with the same weight and resulting torque.
All versions are unbalanced and require adaption to the respective lower end components. All T&O flywheels feature pre-installed and replaceable connecting rod thrust washers, providing increased service-life and restorability.
