JASS Performance steel camshaft locking tool, Mazda MX-5 mk1, mk2 & mk2.5 1.6 & 1.8, 1989 to 2005.
Fits all mk1, mk2 & mk2.5 models, 1989-2005, with both the 24.1mm or 26mm hexes on the camshafts.
Locks the camshafts on the hexes halfway down the shafts, keeping them aligned for doing timing belt changes or replacing the camshaft oil seals.
Note that these have both sizes of hex fittings, and are reversible, so can be swapped around to fit both sizes of camshafts, the small ones (eg. B64J, BP06) or the large ones (eg. B6A7, B6MC, B6KP, BP05. BP4W, BP6D).
