4D6743 Washer for Caterpillar Equipment — SKU 4D6743

The washer is listed for Caterpillar equipment identified by engine and machine model designations 3306, C-9, 973, and 973C. The supplied fitment data identifies the part for Caterpillar engine applications and Caterpillar track-type loader applications.

Fitment

• Caterpillar 3306 engine applications
• Caterpillar C-9 engine applications
• Caterpillar 973 track-type loader
• Caterpillar 973C track-type loader

The model designation 973 is listed in the source data more than once; it is shown once here to avoid duplication. Fitment should be confirmed against the machine serial number and the washer location before installation, because the available data specifies the equipment families and models but does not identify a particular assembly position.
