Talking about flywheel bolts, I seen some ARP flywheel bolts to suit A Series on eBay. The seller states that they are too long and the crank needs to be tapped further. Going by what I read on the thread ARP don't make A series ones so they must be some other car that does suit the A series crank thread. I'm so sh@t with computers I don't know how to put a link up here or post pics for that matter. Oh well they are selling for $50 what do you guys think worth it or not

I'd say worth it. Here's some pics of the damage.

aidin, before that damage occured, had you re-fitted used flywheel bolts or brand new non-ARP bolts?

Re-using flywheel bolts is not worth the risk.

Toyota 4AGE Flywheel bolts fit..even come with two spares in a pakc (8 in total. M12x1.25 thread from memory.

A couple of tricks I've used on high tensile bolts.
#1 Oxy/Acet torch with 000 or smaller tip, run it slightly-lean and de-temper the center of the bolt.
Work quickly, only turning the bolt red, spray with penetrant AFTER the fire hazard has cooled.

#2 Plunge-Cut with a 1/4" Air Die Grinder, use a Ball Burr, double cut makes safer shavings, singe cut burrs make HAZARDS!

This works well removing Titanium Pop-Rivets also.
{Electric Die Grinders mis-used in this way are more hazardous than Air driven}

#3 1/4" Die-Grinder with 1/4" "mill-length" drill bit, these are very short, may find them in Cobalt only or Titanium Coated.
Stay away from standard HSS High Speed Steel Bits.
@ 20-30,000 rpm make sure to shield up your arms, chest, all exposed body parts in case of bit breakage.

LH Drill usage, go "slower" than standard speeds, vary up and down, this sometimes will grab the broken fastener.

Does the "Shoulder" of the bolt go fully through the flywheel?

Check the "Fit" between the flywheel and the shoulder OD of the fastener.
Has the gap gotten wider ?

Going back with the larger bolts seems like a good idea if there's enough meat there.

ARP bolts are good for sure, some mfg's of fasteners {Chinese} do not have the consistency of ARP

60 minutes or some other so-called News had a piece on fasteners a few years ago and the Chinese Bolts featured at that time, were inconsistent compared to American Mfg'd bolts. Though to be fair, I do think the Chinese have gotten better at quality control..

I HAVE distributed a few 100,000 bolts in my time at Southern Company and the Grade 5 minimum standard we have implemented on plated std fasteners has eliminated most bolt problems.

Rusty Wrench

... I refitted my pick of a bunch of used bolts, some of the heads had rounded on the originals when I took it apart

edit: watching initial D isn't helping right now with Takumi's new 11,000rpm engine, I want 11,000 rpm to atomise that fuel!

...So Gary, you wouldn't of happened to get mah crank by now? should be a rule of membership that every member signs in at least once every couple of days at a minimum (not the crap members, they can go suck a rusty hub)

So that's how rusty wrench gets his bearing replaced and lubed, crap members sucking on his rusty hub...

lol

I haven't logged on for a while because I rarely look at this site anymore.

I recieved your crank the other day, would you like me to repair it and send it back or send you up the lighter crank?

Need an answer asap.
