FLSTC Heritage 1999 EVO Asking for advice, exhaust.
I am re-installing original factory exhaust pipes.
I am trying to figure out how to apply pressure to push together the front and rear sections of the "balance" pipe, to firmly seat the gasket.
There are no bolts that pull them together to tightly seat the washer & gasket, just a screw-tight clamp that looks like #11.
(This is the balance pipe, not where the pipes to the head exhaust ports.)
PHOTO: I put a photo where my signature photo was.
(Oh. I am assuming they need squished together)

The Manual doesn't say, section 4-30.
Parts Catalog page 130 illustration and parts list page 133.
Parts 29 and 30 on illustration.
#29 is 65781-82 gasket, original is still inside pipe, looks like a crush gasket in perfect condition but looks like it was never crushed (like exhaust port crush gasket crushes)

#30 is 65782-82 washer, original dropped out of pipe, looks fine, fits fine.


What do I do here?

fwiw These original pipes have only 1,000 miles on them but bike has 40,000 miles; originals were replaced 39000 miles ago with Samson Long Shots, which are destroying my hearing.


I have lightly coated everything with Permatex Copper Anti Seize Lubricant.

 

It all pulls together as you tighten up the headers and the mufflers, mainly the headers.

 

I believe you. I just don't understand how it can seal well with nothing pushing the male pipe end against the gasket inside the female pipe end.

It does push, it just doesn't look like it does and it doesn't push very much......balancer pipes are Old Skool mate.....just a thought....some have a steel spacer ring that pushes on the gasket end.....

 

Sounds like a practical answer, Spanners39. Good enough. I wanted to be sure before I assembled it and got a leak. Yes, there is a spacer ring/washer.

 

If all else fails put some expanding exhaust putty in there.

 

I didn't know if you are joking or serious so I looked for some.

Found Deacon Industries "8875-Thin" thermal reactive paste mechanical sealing compound Max 1,800 F. Thin for real skinny spaces, not permanent. Thin gasket-making, gasket dressing, fills small voids in flanges. MSDS says NOT SUITABLE FOR NUCLEAR APPLICATIONS but my bike is an EVO so no problem. Might not work on twinkies or Hayabusas.

Think I'll just bite the gasket, ride on down to the local Moco, exchange paper for metal, ride on to Thanksgiving, ride home Friday & do it right.

 

NAPA should have it, it's just exhaust assembly paste.

 

My bike has the same gasket/spacer for the crossover pipe, I think you'll find like me, when you tighten it all up it'll seal just fine.
