此活塞是组合式铰接设计的活塞。 此活塞包括也锻造的钢制活塞顶部和一个铸造的活塞裙部。 活塞总成的顶部和裙部由活塞销连接起来。 活塞总成的顶部和裙部以活塞销为枢轴。 所有三个活塞环都由钢制活塞顶部载持。 来自活塞冷却喷嘴的机油流经位于活塞环正后方的腔室。 这些机油用于冷却活塞，提高活塞环的使用寿命。 活塞具有三道环，包括两道气环和一道油环。 三道活塞环都位于活塞销孔以上。 油环为标准油环。 机油经由油环槽内的孔流回曲轴箱。
连杆的销孔端成锥形。 这种锥形使得连杆和活塞在各自的最大载荷区域具有更高的强度。 四个成一定小角度的螺栓将连杆盖固定到连杆上。 该设计使连杆保持最小宽度。 使用更大的连杆轴承时，仍然可通过缸套拆除连杆。
