Specifications

The available technical data for this starting motor group includes the listed weight and external dimensions. The dimensions are stated in centimetres, and the weight is stated in pounds.

The part name describes the complete electric motor group rather than an individual internal motor component. The listed application covers Caterpillar excavator series from the 311, 312, 313, 314, 315, 318, 319, 320, 321 and 323 model ranges. Suffixes such as L, LN, LCR, LRR, LNA, CR, FM, S and SA are retained because they identify the particular machine version specified in the fitment data.

Before fitting, compare the part number, machine model designation and the physical dimensions with the unit being removed. This description does not assign a separate thread specification, mounting position, voltage, rotation direction or included component list because those details are not provided in the available product data.
