hello i have an older omni gear box model 25033 (ratio)1.1.47 do u have any thing to replace it with be nice if i had one little heaver THANKS SAM

A: This item is the heaviest cutter gearbox we have, and without any reference information available from the manufacturer cannot say if it is the most comparable.
Date Submitted: 07/06/2017

In the description it says the unit has "heavy duty ball bearings " on the drawing it looks like it has tapered roller bearings Also can the rotation be reversed by changing the Gear location?

A: From the manufacturer's literature-"Bearings: Roller bearings standard in light duty units. ISO tapered bearings standard in larger units." We have no information about reversing the output direction.
Date Submitted: 03/30/2017

Why is there such a wide range on the max torque spec?

A: Because the input HP range is from 35-83, the max torque specs have that same range.
Date Submitted: 09/20/2016

can gearbox be operated with output shaft horizonatal

A: This box only has one breather vent in the case, behind and above the input shaft at the back of the case. Running the box with the output horizontally would make it necessary for the end-user to plumb in an extension tube to allow for proper venting above the oil level in the box at the very least.
