6E4006 Rotating Group-Pump for Caterpillar

The 6E4006 is a rotating group-pump for Caterpillar backhoe loaders. The part is used in the hydraulic system of the listed Caterpillar machine models and is identified by the equipment manufacturer part number 6E-4006, also written as 6E4006. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The product name “Rotating Group-Pump” identifies the supplied component as a pump rotating-group assembly. The available application data associates this part with Caterpillar backhoe loaders from the 416, 420, 426, 430, 432, 434, and 436 model series. Compatibility should be checked against the machine model and the part number installed on the equipment before replacement.

Fitment

The 6E4006 rotating group-pump is listed for the following Caterpillar backhoe loader models:

• Caterpillar 416C backhoe loader
• Caterpillar 416D backhoe loader
• Caterpillar 420D backhoe loader
• Caterpillar 420E backhoe loader

• Caterpillar 430D backhoe loader
• Caterpillar 430E backhoe loader
• Caterpillar 432E backhoe loader
• Caterpillar 434E backhoe loader

The listed fitment applies to Caterpillar backhoe loaders only. The model designation must be verified because the same machine family may be produced in different configurations, and the installed hydraulic component should correspond to the referenced part number.

For the 416 series, the listed applications are 416C and 416D. For the 420 series, the listed applications are 420D and 420E. The 426 series is represented by model 426C. The 430 series includes models 430D and 430E. The remaining listed applications are 432E, 434E, and 436C.

Cross-reference numbers

Numbers 6E-4006 and 6E4006 represent the same referenced number in two written formats: the first includes the separator used in the Caterpillar numbering format, while the second omits the separator. The SKU for this product is 6E4006.

The available product data does not specify additional supplier numbers or separate replacement numbers. Therefore, no other cross-reference numbers are listed for this part.

Specifications

The dimensional data describes the supplied rotating group-pump as 12.1 cm long, 12.1 cm wide, and 13.3 cm deep, with a listed weight of 10.8 lb. The source data does not specify mounting hardware, seals, gaskets, fasteners, or other additional components included with the pump. The part should therefore be treated as the rotating group-pump only unless the supplied package documentation states otherwise.
