Install New Assembly into cam cavity Hold the new assembly in front of the cavity and observe the flats on the crank shaft and the flats on the pump. These have to line up. Rotate the rear wheel to rotate the crank shaft or use your finger to rotate the pump assembly to line up the flats. Confirm that the lifters are up out of the way. Confirm that the new orings are in place. Slide and rotate the new assembly into the cavity observing the crank shaft coming through the pump assembly. If everything is right, it should slide right in place. Snug three cam plate bolts, forming a triangle, onto cam plate to seat the assembly and rotate the rear tire to rotate the pump assembly to center it. 201936 Torque pump assembly bolts (4) in sequence and to specs. Rotate rear tire a few more times. Attach plate assembly in place using six cam plate bolts. Torque bolts in sequence and to specs. Place the .110 shim over the rear cam shaft. Place cam and crank sprockets on ends of shafts and push them all the way on. Use straight edge to determine that sprockets edges line up within tolerance. My sprocket edges lined up perfectly and required no further shimming. Apply/remove shims under cam sprocket until sprocket edges are within tolerance. 201938 Remove sprockets, making sure proper shims stay in place. Attach primary chain to cam and crank sprockets making sure the dots line up. Slide cam and crank sprocket with chain attached over shaft ends and into place making sure the dots remain lined up. Rotation of engine/crank shaft may be required. Lock cam with crank sprocket or lower vehicle to keep engine from rotation while you torque both bolts in sequence and to specs. Attach well lubed primary hydraulic tensioner/shoe assembly and torque to specs. Remove pin that holds shoe in place.
