This tool is designed to install the cam seals in 4 & 6 cylinder engines for Mazda, Nissan & Toyota/Lexus engines that have 10 & 12 mm X 1.25 cam bolts.
These engines are mounted transversely which puts the camshaft end in very close proximity to the shock tower making replacement of the cam seal extremely difficult using conventional methods.
Screw the threaded rod into the cam end, slide the body over the rod against the seal and press in the seal using the nut provided.
