What have you found or fabricated to tighten the 13 ATF hex nut on 914-6 heat exchanger passenger side? I think that's cylinder number 1.
I'm sure this is probably mechanics 101, but I'm having a hard time with it. I've tried every combination of 1/4 socket, u-joint, wobble extender, flex driver I can find. No room for a box or open end wrench as 2 sides are blocked by bracket and pipe. Nothing I've tried provides enough engagement to properly tighten it.  |

Hi Dennis, Yeah there is a special wrench that is bent kind of like a Z that allows you to get in there and tighten that nut with ease. Good luck, Michael (IMG:style_emoticons/default/beerchug.gif)

SSI included either a 12mm or 13mm z shaped wrench with their replacement exchangers. Maybe ask around. I have used 12mm across the flats nuts and seems to make it easier.

I use a stubby 13mm wrench. I did see S wrenches on Amazon. Never seen a Z wrench

The support strap needs the hole slotted so it can move away , If you insist on a 13mm hex.. and your studs short..

Sadly yes (IMG:style_emoticons/default/agree.gif) ,not enough thread to support the hex nuts or the barrel nuts if all studs are the same ,well prior to fitting my exhaust I removed one bad one and ordered 12 new studs from Pelican , length was spot on . The only fix I can see is to restud the heads ..don't think there is any other solution . |

Want to say I used a ratcheting box end, swivel head wrench.
I'll see if I can get a picture of it tomorrow. |

Yea, unless that’s some sort of optical illusion, you’re going to have to fix that.
