I have 4 each generation 3 Montero (2001, 02 & 03 years) with 3.5/3.8 L motors. From what I understand all the crank pulley / harmonic balancers have the same holes in them for inserting the "special tool" to remove and reinstall / tighten the crankshaft pulley bolt.

Does anyone have the exact dimensions I need to make the tool? I'm going to make one with 2x4 wood, drill and jig saw.

I can't find these anywhere confirmed.

Thanks!
