Power TAKE-OFFs (PTOs)

Easy-to-mount unit consisting of a clutch assembly with shaft and bearings in a rigid cast iron housing. Designed for manual operation on all internal combustion engines with standard SAE flywheel housings from No. 6 to No. 00. Triple-plate 11.5" to 21"; double-plate 11.5' to 18'; single-plate 6.5" to 14". Capacities to 1670 horsepower and 8400 lbs.-ft. torque. All Twin Disc Power Take-Offs come standard with composite clutch plates which have wear resistant teeth for longer life and sealed-for-life pilot bearings for reduced maintenance. For high speed applications nodular iron drive rings are available.

RUBBER BLOCK DRIVE PTOs
This special purpose PTO is intended for heavy-duty applications not requiring a cut-off clutch. The need for a flywheel pilot bearing has been eliminated in some models. Twin Disc's time-proven rubber block drive absorbs the minor misalignment usually found between the engine fly-wheel and the PTO connecting member. Depending on the load to be transmitted, a single or double row of rubber blocks can be used.

STRADDLE BEARING PTOs
The Straddle Bearing PTO was explicitly designed for high horsepower, high side load, heavy duty applications. Rugged benefit features include cast iron housings, cylindrical roller bearings, nodular iron drive ring and ball bearing throw out collar. Unique style sheave housing easily accepts a 14" diameter 10 groove sheave, This sheave housing allows for belts to pass inside and/or outside of housing. Housing versatility also allows for repositioning. Additionally, the need for an engine mounted pilot bearing has been eliminated. BOM SP314S106 with the extended auxiliary shaff is pictured above.
