Fitment is specified by equipment model and machine series. The part is listed for the Caterpillar 776B and 777B off-road dump truck series, as well as the Caterpillar 631E and 637E wheeled tractor-scraper series. Compatibility should be checked against the machine model and the existing part number before installation, particularly where equipment has been modified or components have been replaced during service.

Cross-reference numbers

The numbers 6Y1363 and 6Y-1363 identify the same disc in the supplied product data. The SKU uses the continuous format, while the hyphenated format is shown as the corresponding equipment-part number. No additional supplier numbers or replacement numbers are specified in the available data.

Specifications

The dimensional data identifies the disc by its inner diameter, outer diameter, and thickness. The listed length, width, and depth are provided separately from the inch-based disc dimensions and are reproduced as supplied in the product data. Weight is stated in pounds, while the overall listed dimensions are stated in centimetres.

The part data does not specify the friction material, number of discs in a set, mounting hardware, or additional components included with the disc. The available configuration is therefore a single disc identified by SKU 6Y1363, with no kit contents stated.
