Solution to Mount and Drive Caterpillar 3406 Pumps on Bosch Test Benches

EAN: M8231-3406BH

Part Number (SKU): 8231-3406BH https://www.injectionpower.com/web/image/product.template/85085/image_1920?unique=4c4fe21
(0 review)

This setup is specifically designed to mount and drive Caterpillar 3406 series pumps on Bosch test benches (EPS 708, 815 and similar models).

The configuration is based on our standard kit 8231-3406 (for Hartridge benches), but it is delivered without the Marbed 9422-H2 interface spacers, which are only required for Hartridge machines due to their different centering height.

🔧 Compatibility:
* Caterpillar 3406 pumps
* Bosch EPS test benches (EPS 708, EPS 815, etc.)


📦 Included in the kit:
* Mounting flange
* Drive shaft
* Dedicated support brackets
  *(Note: Marbed 9422-H2 spacers are not included — not needed for Bosch setups)*

For customers using Hartridge test benches, please refer to item 8231-3406, which includes the necessary spacers for correct alignment.

Technical Note

The only difference between the 8231-3406 (Hartridge) and 8231-3406BH (Bosch) versions lies in the mounting height adaptation.
The core components — flange, shaft, and supports — are exactly the same.

If you plan to use this kit on Hartridge benches in the future, you can simply add the Marbed 9422-H2 interface.
