Schley 99700 DOHC Valve Lifter Tool
The Schley Products 99700 is a professional-grade hand tool designed to depress valve springs for hydraulic lifter removal and replacement. Its thin profile allows it to slide between the cam tower and cam lobe over the valve spring retainer. This tool suits mechanics and DIYers working on dual overhead cam engines.
For DOHC lifter service, not general spring work
It is intended specifically for accessing hydraulic valve lifters on dual overhead cam configurations. The slim design targets the narrow clearances found in those cylinder heads. Technicians needing a standard valve spring compressor for broader cylinder-head work or single overhead cam layouts should look at a different tool style.
Thin profile for cam tower clearance
The decisive specification is the tool’s thin design, which lets it fit between the cam tower and the cam lobe to reach the valve spring retainer. Without this clearance, the lifter cannot be serviced on the target DOHC engines. Buyers must verify their engine architecture matches this access requirement.
