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.
