CATERPILLAR-BELT-TENSIONER

190-0643 is the counterpart tensioner in Caterpillar's 190-064x series, sharing the same spring-tension design as its sibling part but specified for a different engine configuration or belt routing on the accessory drive. Getting the exact reference right matters here — visually similar tensioners can carry different spring rates, and fitting the wrong one either under- or over-tensions the belt.
