Necessities for Exhaust System Removal/Installation
The exhaust pipe had been installed and the flange was bent due to over-tightening.
The Gasket was still crushed and stuck to the Cylinder.
With the Pick tool, I forced it off by sticking the Pick while pulling on the Gasket.
Cylinder was cleaned with foam Carburetor cleaner and Dustcloth, and exhaust pipe was cleaned with Oil stone.
When installing the Gasket, it is best to install it on a slightly inclined surface with the Front facing up so that the Gasket will not fall off.
Put in a new Gasket, tighten the exhaust pipe by hand, and set the Quantity:Pair (for Left and Right) Tighten it to even etc.
If you get to the point where it will not tighten, adjust the exhaust pipe up or downQuantity:Pair (for Left and Right) The first time, the client shakes the machine to see if it is settled. Then tighten it again by hand.
When it got to the point where I couldn't tighten it anymore, I tightened it with an Offset wrench at about 90-degrees to 180-degrees to even etc.
If there are no exhaust leaks, the system is complete.
I think it is loose, so I recommend checking regularly or double nut. If you tighten it too much, it is not the end of the world.
I did not take pictures of the work since it is a friend's vehicle.
