Posted September 10, 201410 yr comment_455095 Looks like I will need to put a helicoil in at least one of my crank/flywheel holes. They are not out yet, so I don't know the size and thread. I am sure there are lots of smart folks out there that can tip me off so I can order the right parts in advance. Also I will need new flywheel bolts. So any advice on buying those would be appreciated also. Thank you for your knowledge and help!

September 10, 201410 yr comment_455096 Your dealer might be able to get the bolts.BOLT-FLYWH :: Nissan Parts, NISMO and Nissan Accessories - Courtesyparts.comI had some bolts and old lug nuts in the garage. The flywheel bolt is the same thread as a lug nut. 12mm x 1.25.

September 10, 201410 yr comment_455155 I'm not sure if I would want to put helicoils in my crankshaft. It might be very difficult to install them, too. Perhaps one of the truly mechanically inclined would chime in...zcars, John Mortenson, Carl Beck? Admittedly, I am not a professional mechanic. It just gives me pause.Cheers, Mike Link to comment https://www.classiczcars.com/forums/topic/50024-flywheel-bolt-size-and-help/#findComment-455155 Share on other sites More sharing options...

September 15, 201410 yr Author comment_455473 Good news! The bolt was stripped! Left remnants of the bolt in the threads and the local hardware was open today (sunday) and had the proper tap! Flywheel off, threads cleaned out, replacing the rear seal and taking the flywheel to be resurfaced tomorrow!Whew! Thanks my good friend that helped my sooo much, I am a smiling Z guy again!
