Description
While this bolt isn't typically replaced with a timing belt change, if yours is especially old (i.e., it's been re-torqued many times thanks to many timing belt changes), it's not a bad idea to replace it.
We recommend using red Loctite and then torque the bolt to 80-87 lb-ft.
Fits 1990-1991 Miatas. 1.6 engines could have a small nose crank (1990-1991, four slots in the face of the crank pulley) or a big nose (1991+, 1991-1993 have eight slots in the face of the crank pulley, 94+ have no slots) - this bolt is for small nose engines only, it won't fit big nose engines.
