Previous
Speed up top-end work without pulling the head. The US PRO 5590 overhead compressor lets you compress springs and access collets/keepers to replace valve springs and stem seals on most OHV/OHC/CVH engines. A reversible jaw adaptor adapts to different retainer styles, while the automatic cam-action lock holds compression at a predetermined setting—freeing both hands to remove or refit keepers. Designed for use with the cylinder head fitted; avoid use on engines with deep-seated valves where reach is insufficient.
