1545562 Flange for Caterpillar Equipment

The 1545562 flange is a replacement flange used on Caterpillar equipment, including Caterpillar engines and excavators. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The part is identified by the Caterpillar reference format 154-5562 and the numeric SKU 1545562. The available application data lists this flange for specific Caterpillar engine and machine configurations, including the 3116 engine and several 320B and 322B excavator models.

Fitment

The flange is listed for the following Caterpillar equipment models and series:

• Caterpillar 3116 engine
• Caterpillar 320B excavator
• Caterpillar 320B L excavator
• Caterpillar 320B N excavator
• Caterpillar 320B S excavator
• Caterpillar 322B L excavator
• Caterpillar 322B LN excavator

The fitment information includes both Caterpillar engine and Caterpillar excavator applications. Model suffixes must be matched with the machine identification and the part number before installation, because the listed 320B and 322B versions are specified separately.

Cross-reference numbers

The numbers 1545562 and 154-5562 identify the same flange reference in different formats. Use the number shown on the removed part, equipment parts documentation, or applicable service records to verify the required component.

Specifications

The stated dimensions are 36.2 cm in length, 36.2 cm in width, and 4.4 cm in depth. The listed weight is 3 lb. No additional material, thread, fastener, seal, or kit-content information is provided for this flange.
