Features & Benefits

Balanced. Durable. Powerful. It all adds up to a rammer engine like no other. Unlike competitors, Subaru designed its engines from the ground up strictly for rammer applications. They are carefully balanced and engineered to be lightweight for optimal performance, yet able to deliver the most power and torque.

Cast-Iron Cylinder Liners Resist wear and enhance durability for better compression, more power and prolonged engine life.

Dual Ball-Bearing Crankshaft Support Reduces friction and increases power delivery to the crankshaft.

Vertical Cylinder DesignMaintains an ideal center of gravity to effectively transmit power to the ground.

Specific Rammer Design Ensures a unit that’s balanced, lightweight and powerful for demanding rammer applications.

Low Oil Pressure Sensor (ER12)Shuts off the engine if oil pressure level drops too low.

Rammer EngineRammers present a special engineering challenge. The engine must withstand both the vibration of the compactive force and the high dirt

and dust environment. Additionally, rammer engines require a high degree of specialized design to integrate with the rest of the machine for

maximum performance. The rammer design requires that the entire machine be balanced on the center of the foot in both the front to back

axis and side to side axis.

Because the engine is mounted to the side of the rammer’s leg, the lesser the width (W) of the engine, the less the rammer needs to be

angled (A) forward to balance the machine over the foot. As the rammer angle (A) is increased, the compaction force (F1) that impacts the

ground is reduced and the backward force (F2) increases – propelling the rammer forward and reducing compactive force. To maximize

the compaction force, Subaru rammer engines are designed specifically for rammer applications. All Subaru rammer engines are balanced

close to the mounting face as well as evenly on the side to side axis for optimum compaction performance and easy operation.
