Replacement GR16E401-1 Speed Reducer for Morbark

Cotta Model GR16E is a single-stage reduction gearbox designed for direct mounting to industrial engines via an SAE flange and driven in standard engine rotation (CW facing input shaft). This unit incorporates an idler shaft to provide output rotation same as input. Our speed reducers match the optimum engine speed to the optimum driven equipment speed, allowing your engine and load to both operate at ideal efficiency.

Typical uses include pumps, dredges, compressors, crushers, drills and high-performance machinery for oil & gas, construction, mining, and other industrial applications. Our heavy-duty gearboxes are designed for use with diesel engines, electric motors, PTO’s, and other prime movers. This particular unit here is a replacement GR16E401-1 Speed Reducer which will be used in the forestry market on a Morbark Tub Grinder in New Hampshire to chip limbs and branches. Cotta has supplied replacement gearbox units as well as service parts for many years for Morbark Tub Grinders worldwide.

Cotta Speed Reducers

Cotta Speed Reducers are designed for use with the commercial offerings of major industrial engine manufacturers.  The reducers are furnished with bell housings to mount directly to the engine’s SAE flywheel housing.

Speed Reducers are available in increasing sizes from nominally 100 HP to 2200 HP, and with flywheel housing sizes from SAE 4 to 00.  At approximately 2200 HP capacity the gearboxes become physically too large to direct engine mount at which point independent mount gearboxes are offered.

Speed Reducers can be coupled to the engine by a variety of methods, including clutches, drive plates, or torsional couplings depending upon the application requirements.

Some of the reducers are suitable for driving side pull loads using belts or chains on the output shaft. Consult with Cotta Engineering before selecting a gearbox for use with a side pull load.

Cotta’s catalog is organized into a standard-ratio section and a high-ratio section with each sorted from smallest to largest by power capacity. These gearboxes are considered “standards” , but are not the only reducers available. Cotta offers modified standard boxes, as well as full-custom and purpose-built.
