Hi, new user from Atlanta. I have a 2002 Road King Classic and am pretty sure I developed an exhaust leak last Saturday. I have a HD factory service manual on order but doubt it will be here before I am supposed to go on a ride this Sunday. Can someone please share the torque specs and tightening sequence for the front and rear exhaust manifold nuts? I know they are tightened in a couple of steps and go top to bottom and vice-versa but not sure what those values are for the Touring models.


Thanks in advance!
Tommy

 

use antiseize paste on the thread- this goes alot looser than you think INCH pounds...some guys bust studs

a. Tighten the bottom nut of the rear cylinder head
exhaust flange to 9-18 in-lbs (1-2 Nm). Tighten the
top nut to 100-120 in-lbs (11.3-13.6 Nm). Final tighten
the bottom nut to 100-120 in-lbs (11.3-13.6 Nm).

b. Tighten the top nut of the front cylinder head exhaust
flange to 9-18 in-lbs (1-2 Nm). Tighten the bottom
nut to 100-120 in-lbs (11.3-13.6 Nm). Final tighten
the top nut to 100-120 in-lbs (11.3-13.6 Nm).

 

Thanks for the reply. I finally had time to take a look at the bike and the two flange nuts on the rear cylinder are missing. Strange that it never hinted at a leak until the nuts had fallen off.

 

sounds like an easy fix.

Serrated flange nuts are money well spent. 5/16x24 thread.
