Determining Parallelity of Two Piece Camshaft Sprockets
NOTE: This procedure is performed only on models with two piece multiple hole chain sprockets
Checking

Before measuring, move the intermediate shaft in axial direction towards the flywheel to make sure the support collar of the bearing is seated
correctly.
