Removing exhuast manifold ... are you kidding?

[1970_mgb]

I just started a top end rebuild on my 2000 Sportster Le (947 2 stroke) . Got to the point of separating the cylinder jug from the exhaust. I am trying to remove the tuned pipe cone to access the 8 cap screws on the exhaust manifold.
The manual says there are 3 allen head bolts ( which I can see easily and get to) and one nut to remove. (part 10 in the exhaust parts list) I cannot see it or feel this nut , it must be underneath the cone somewhere. It is not even clear in the parts list where it is or what it is attached to. There must be some way to get at it but how??

The manual says
"As a first step, torque Allen screws no. 9 at tuned
pipe head flange to 25 N•m (18 lbf•ft).
NOTE: Also, torque nut no. 10 to 18 N•m (13 lbf•ft)
using the polygonal key (P/N 529 035 505)."

and that polygonal key would be a box wrench??? Note: wrench in French = clé = key

Under the photo it says "Torque Allen screws and nut (not shown) to 25 N•m (18 lbf•ft)"

Not shown? No kidding!!

Im sure there is a simple answer to this. Need help

Thanks

On my 787, there were three allen bolts & one hex nut that needed a box-end wrench to remove; I don't remember the size, maybe 13mm? I could see the nut, however when i looked under the tuned pipe. The setups may be entirely different, sorry.

It's under there and a real bugger to remove. It's a combination of loosen and wiggle the exhaust pipe outward to actually get it loose. 13mm sounds right. Of I remember correctly, you can only get 1/4 turn at a time. I'd like to meet the engineer who came up with that design!

Got it with a regular wrench thanks. Not as bad as i thouht if you dont mind working upside down.

LOL I'll be upside-down in mine this weekend, getting a couple bolsters off to re-cover.
We stayed in Confederation Basin for our long weekend at the end of May (in the Sundancer of course! not the jet boat); love it there. Ate at The Works, our new-favorite burger place!
