JASS Performance crankshaft locking tool MX-5 NA/NB/NBFL

JASS Performance crankshaft lock / fixing tool for loosening the crankshaft pulley. When loosening the central screw of the crankshaft, the problem is often that the screw cannot be loosened. This fixing tool can be used to secure the crankshaft against twisting and to loosen the screw.

The surface is powder coated red.

Note that this does NOT fit the very early NA 1.6 models made in 1989-90, which have 4 slots in the front of the outer crankshaft. It fits all later models where the outer pulley is screwed to the pulley with 4 x 10mm cap screws.
