后轮轴机油滤清器 (1) 安装在后轮胎壳体后面。 从后轮轴机油流量控制和安全阀流出的油经过进油管流至后轮轴机油滤清器 (1) 。 之后这些油经过回油管流回到后轮轴机油流量控制和安全阀。
滤清器旁通开关 (2) 向电子控制模块（ECM）发送输入信号。
从进油管流出的油流入进口油道。 机油会充满滤芯 (5) 和壳体内侧之间的空隙。 正常工作时，油将会流过滤芯 (5) 。 然后，该机油流经出口油道。 滤芯 (5) 可过滤掉机油中的所有碎屑。
如果滤芯内塞满碎屑，机油的流动阻力将导致滤清器内部压力增加。 如果机油压力达到旁通压力，压力油将使旁通滑阀 (3) 移动。 机油随后环绕滤芯流至后轮轴机油系统。 滤清器旁通开关 (2) 将此信息通知 ECM。 当机油没有流过滤芯 (5) 时，机油中的碎屑可能会损坏系统中的部件。
必须采用正确的保养程序来确保滤芯 (5) 中不会充满碎屑，从而避免其阻止清洁的机油流动。
