To Service Timing Chain:
Remove muffler and with a 1/2" impact wrench ,a 12" extension bar ,an angle 
drive and a shallow 35 or 36 mm socket, assess the pulley from beneath the 
facia. Rotate pulley keyway to 12' o'clock before removing pulley. Remove 
timing cover and adjust chain as per manual direction ( see below ).Removing 
the pulley nut will require 120# psi air pressure and several cycles of air 
tank pressure.Stay with the effort as it will come off. Replace the nut with 
the same pressure and hold for 20 seconds to tighten.In the event a shallow 
socket cannot be located, cutoff a long socket leaving 1/2" surface .
