features
- Large oil reservoir provides efficient heat dissipation and lubrication for longer life
- Housing is straddle milled top and bottom for precise alignment
- Internal baffles ensure positive, leak-free venting
- Rugged housing fabricated of fine-grained cast iron for maximum strength and greater precision during worm and gear alignment
- Bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to increase thrust and load capacities on size 713 to 760
- High strength steel output shaft ensures capacity for high torque
- Pipe plugs allow easy fill, level and drain in any mounting position
- Super finished oil seal diameters on both input and output shafts extend seal life
caution
- Because timing belts have an inherent, gentle side thrust, it is necessary to use at least one flanged pulley to prevent the belt from riding off
