Jims Mini M8 Valve Spring Compressor for Harley-Davidson

Used to replace valve springs, upper collars and valve seals without disassembling the cylinder heads on Milwaukee Eight engines.

It works with the engine in the chassis.

It is necessary to remove the rocker cover and the rocker arms.

The tool is installed on the rocker arm shaft.

The cylinder must be filled with compressed air to keep the valves in the cylinder head once the spring retainers are removed.

The mechanic can rotate the tool and thus compress the upper collar of the valve spring, exposing the retainers to remove the upper collar, valve spring and seal.

Fits: Softail 18-24; Touring 17-24
