必须检查活塞冷却喷嘴 (5) 机油流的位置。 插入一根直钻杆，钻杆的直径刚好适合各个活塞喷嘴节流孔。 活塞喷嘴节流孔的内径 (3) 为 2.4 mm (0.09449 in)。 活塞喷嘴节流孔的内径 (4) 为 1.5 mm (0.05906 in)。 钻杆模拟正常工作压力下的机油流。 将钻杆置于节流孔 (4) 中。 钻杆必须在位置 (2D) 处穿过一个圆圈，圆圈直径为 15 mm (0.59055 in)。 将钻杆置于节流孔 (3) 中。 钻杆必须在位置 (1D) 处穿过一个圆圈，圆圈直径为 9 mm (0.35433 in)。
注: 切勿让钻杆损坏活塞喷嘴节流孔的内侧表面。 内侧表面的损坏可能会改变机油流。
