   If the free length is less than the minimum, replace the compression spring.

2. Temporarily install 2 new exhaust pipe gaskets to the front exhaust pipe assembly for tail exhaust pipe assembly and tail exhaust pipe LH side.
3. Using a plastic hammer and wooden block, tap in each exhaust pipe gasket until its surface is flush with the front exhaust pipe assembly.
   NOTE:

   • Be sure to install the gaskets in the correct direction.
   • Do not reuse the exhaust pipe gaskets.
   • Do not damage the exhaust pipe gaskets.
   • Do not push in the exhaust pipe gaskets by using the front exhaust pipe assembly when connecting it.
