3-gear
boxes 3G-250-275 HP

Use for tractors or equipment that can go up to 250 HP or 275 HP at 1000 rpm like a reducer or an accelerator. Ideal for snow blower or industrial machinery when direction of rotation must stay the same.
This gearbox is ideal for replacing the chain cases because it is more efficient, more quiet and more durable.
Machined precisely on CNC machines, cast iron housing with fins to assure good cooling and excellent stiffness.
All 3 helical gears are made of alloy steel. These gears are heat treated to make them more resistant to wear and impact in case of a sudden jam.
High efficiency of 97-98%. Quiet running and reduced maintenance.
Standard ratio 1:1, 1.78:1, and 1.86:1. Other ratio are available on special order.
Male input shaft 1 ¾ -20 splines.
Female output 1 3/4 –20 splines or 2” –23 splines.
6 tapered roller bearings for high performance and durability. To facilitate a precise adjustment of each pair of tapered roller bearing, we designed a cover for each of the 3 rotation axis. These covers increase the impact resistance and make it easier for the maintenance or the eventual repair.
Double lips rubber seals. Inspected and leak tested before shipping.
9 machined mounting post threaded ½-13 UNC on each side of gearbox to facilitate adequate installation.
One year warranty against manufacturing defects.
Use 80w90 gear oil. Shipped without oil.
