Direct Crankshaft Mounting

Direct crankshaft mounting on most engines eliminates any “factoring” for drive-train losses. The 5″ (or optional 7″) rotor’s arbor fits directly onto standard ¾”-diameter 3/16″-keyed shafts. An optional 9″ absorber fits 3° (1:10) and 4° (1:7.5) tapered PTOs. If clearance is available, engines can be tested right in the vehicle’s chassis – using an optional rear-axle adapter.

Crafted to Perfection

Precision designed and manufactured for flexibility, strength, high accuracy, and reliability. Each water absorption brake, torque arm, and load-valve is beautifully CNC machined out of anodized aircraft billet aluminum and 17-4 heat-treated stainless steel.
