On-car Valve Spring Removal Tool to suit Ford 6 Cylinder DOHC
Our Patented (Patent # 2006100221) tool is a simple device to facilitate quick and easy removal of valvetrain
components in Ford 4.0L VCT twin cam Barra engines. The unique features of the tool are as follows:
• The cylinder head does not need to be removed to gain access to the valve springs
• Once the tool is fitted, all 4 valve springs per cylinder can be changed concurrently
• No special skills are required to use the tool
• The possibility of collets falling into the engine is greatly reduced
The tool saves many hours of labour when changing one or many valve springs, valve stem seals or retainers - a
mechanic can change all 24 springs in about 3 hours. Changing valve springs is very common due to the varying
tensions of standard springs and their rapid deterioration in service, which in turn caused erratic idling and drivability
issues. They are also regularly changed in Ford turbo vehicles as higher boost can bring about premature valve float

To use the tool, simply remove the camshafts, fit the tool to number #1 cylinder and the 4 springs can be changed
in about 10 minutes. Refit the tool to the next cylinder in sequence and continue until all are changed, refit the cams
and the job is done!
