8N0989 Center Manifold for Caterpillar Equipment

The 8N0989 is a center manifold for Caterpillar equipment and is used in Caterpillar engine, generator set, generator, and industrial engine applications. This is a new aftermarket manifold manufactured by CTP (Costex Tractor Parts).

The part is identified in the supplied application data as a center-position manifold. The listed equipment coverage includes Caterpillar 3412, Caterpillar 3412C, and Caterpillar SR4 models or series. The part number is also written in the form 8N-0989.

Fitment

Fitment information identifies the manifold for the Caterpillar equipment and applications listed above. The available data does not provide a complete machine serial-number range or a more detailed breakdown of individual configurations, so compatibility should be checked against the equipment identification and the part number before installation.

Cross-reference numbers

The numbers 8N0989, 8N-0989, and 8N989 refer to the same listed part-number family in the available product data. Number 1078112 is also listed as a corresponding number for this manifold. Cross-reference data should be compared with the marking on the removed component and the equipment parts documentation when several revisions are used within the same equipment series.

Specifications

The supplied dimensional data gives a length of 21.27 cm, a width of 11.25 cm, and a depth of 11.25 cm, with a listed weight of 8.35 lb. These dimensions describe the complete listed part and do not specify individual port sizes, mounting-hole spacing, thread type, material, gasket requirements, or included hardware.

The product data identifies the component only as a center manifold. No separate gaskets, fasteners, seals, fittings, or other installation parts are specified as included. The supplied information also does not state the material composition or provide a technical drawing, so those parameters are not listed here.
