1R0659 Engine Oil Filter for Caterpillar Equipment
The 1R0659 engine oil filter is used in the lubrication systems of engines installed in Caterpillar equipment. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).
The filter is identified by the Caterpillar part-number format 1R0659 and is also listed as 1R-0659. Its function is to remove particulate contamination from engine oil before the oil continues through the lubrication system. The contaminants may enter the oil during engine service or be produced through wear of internal components.
