4Pages

The WPT® Mechanical Power Take-Off consists of a lever-actuated clutch with a shaft and bearings mounted in a rigid cast housing. The Mechanical PTO is designed for inline and sideload applications on all internal combustion engines with standard SAE industrial flywheel/flywheel housing dimensions. • Sealed-for-life pilot bearings eliminate lubrication problems. • Ball bearing throwout collars are optional on 10”, 11 V2”, 14” and 18”. Standard on the 311 PTO. • All drive rings are ductile (nodular) iron or steel. Double main bearings Support plate for 311, 214, 314 is required for sideload applications and recommended for inline applications. Support plate for 318 is required for both sideload and inline applications.
