96 m/t NSX - can anyone confirm the crank pulley tool hex size?

[-TJ]

Hi - First post here, I've been researching the DIY timing belt job. I've got the 91 service manual .pdf as well as the Gary Kentosh writeup from the FAQ section.

In a week or so, I've been nominated as the family Honda/Acura uncertified tech to perform a timing belt etc. service on a '96 m/t NSX. I have a 50mm crank tool, and thought I was all set until reading this thread:

So, am I correct in concluding that an m/t '96 will need a 45mm crank tool?

Yes, 45mm for 96 M/T NSX

Thanks Larry! Looks like I'll be putting a 45mm attachment on my homebrew Civic/Integra crank pulley tool

I hope you have a strong 3/4" drive breaker bar for the NSX crank pulley nut.

Hopefully a nice strong impact gun is at your disposal.

Yep, shouldn't be a problem. Knock wood.

Larry wasn't kidding...
My IR 1/2" impact wouldn't budge the crank bolt. Luckily, my neighbor owns the 1" hoss. That gun bucked once and the bolt was out.

Jees....what do you guys use to torque back to spec?

 

[Larry Bastanza]

I have a 250 ft.lbs. Torque wrench for tightening it.

I'll be borrowing the same neighbor's 3/4 drive torque wrench - 90-600#. The thing is about 5' long.

Thanks NSX Prime! All finished up today - took me about 29 hours over the past 9 days, including special tool fabrication. The motor fired right up like nothing had even happened.
