动力传动系油泵是一个三区段齿轮泵。 泵安装在变矩器壳体的右下侧。 泵由变矩器壳体上的齿轮驱动。
齿轮 (2) 、 (4) 和 (6) 由通过变矩器壳体中的齿轮驱动的轴驱动。 齿轮 (2) 带动惰轮 (10) ，同时齿轮 (4) 带动惰轮 (9) ，齿轮 (6) 带动惰轮 (8) 。
操作期间，油从伞齿轮壳体通过泵体 (3) 中的进口油道进入泵的泵段 (B) 。 然后，油会充满齿轮轮齿间的空隙。 当齿轮转动时，将通过泵体 (3) 中的出口油道输油，以便向变速箱控制阀和制动器控制阀供油。 来自泵段 (B) 的油还流向变速箱主安全阀。 任何流过安全阀的油与来自泵段 (A) 的润滑油汇合。
从伞齿轮壳体进入泵段 (A) 的油还流过泵体 (3) 中的进口油道。 然后，油会充满齿轮轮齿间的空隙。 当齿轮转动时，将通过泵体 (5) 中的出口油道输油，以便向变矩器供油。 这些油还向制动器、伞齿轮和变速箱提供冷却和润滑。
油从变矩器油池经滤网，然后经过歧管 (1) 中的油道流向泵扫油段 (C) 。 油的泵送方式与其他段相同。 油通过歧管 (1) 中的油道流出，进入伞齿轮壳体中的储液罐。
