KamAZ Sleeve + Piston Set – Euro 4 | Thumb Slot | 1ml Piston Volume (740.602-1000128-01)

Description

The KamAZ Sleeve + Piston Set 740.602-1000128-01 is a complete, high-quality cylinder group solution specifically engineered for KamAZ Euro 4 diesel engines. Designed for precise combustion, efficient heat management, and long-term mechanical reliability, this set is ideal for overhauls, rebuilds, or performance restoration.

At the core of the set is a Euro 4-compliant piston featuring a thumb slot design. This innovative geometry improves combustion chamber dynamics and assists in reducing thermal stress. The piston has a calibrated volume of 1 ml, which is critical for precise air-fuel mixture control — helping to meet modern emission standards while maintaining power output and fuel efficiency.

Paired with the piston is a precision-machined cylinder sleeve designed to provide an ideal bore surface for piston ring seating. The sleeve is manufactured with consistent wall thickness, high wear resistance, and optimal heat dissipation properties. This ensures that the piston operates smoothly under high pressure and temperature without excessive friction or cylinder deformation.

The 740.602-1000128-01 set also supports tight sealing through compatible piston rings (not included), helping minimize blow-by and oil consumption. Together, the piston and sleeve ensure smooth engine cycles, reduced vibration, and improved engine responsiveness in demanding working conditions.

This assembly is built for heavy-duty KamAZ trucks operating under strict emission environments and is fully compliant with Euro 4 standards. It provides exceptional mechanical efficiency, a long service interval, and reduced total cost of ownership.
