View model pageGeneral guidance
In general, a pulley-pump drive is a drive pulley used to transmit rotation from an engine-driven belt system to a pump. Pulleys like this sit on a rotating shaft and are typically matched to belt type, groove profile and shaft arrangement, so exact suitability depends on the specific machine configuration.
Use part number 0065945 as the reference when searching or requesting this item from Caterpillar catalog listings. Before ordering, confirm the machine model, serial range and any qualifiers recorded for the catalog association, since the listed alternator-group occurrences do not establish compatibility for every configuration.
