pushrod adjustments and hydraulic lifters because we make many camshafts and pushrod sets for the h/d accessory market we frequently hear the following question what is the proper procedure for adjusting the pushrods on my bike the diagram at the left shows a cutaway schematic view of an adjustable pushrod and hydraulic lifter assembly labels identify some of the components note that for this explanation no check valve is shown but it is part of the lifter when hydraulic lifter units are first assembled with no pushrod present the compression spring pushes the hydraulic unit and pushrod seat upwards until the pushrod seat contacts the lower edge of the retaining ring at this point the hydraulic unit cannot move any further upwards it can however move down approximately .150 inches this downward travel is the adjustment range in other words the adjustment length starts at 0.0 and can be as much as .150 inches a correctly set adjustment positions the hydraulic unit in the middle of t

cam gear noise ev 80 and shovel 74 80 how to find it and eliminate it why do cam gears cause noise in the last few years there has been more interest in quieter engines since cam gear noise can sound like bad lifters we thought the following section would be appropriate whenever the roller follower on a cam lobe passes the maximum lift point the forces on the cam drive gear tooth change direction if more than .002 inches 005mm backlash is present between the cam and pinion gear this directional change of force will result in an audible click as the backlash moves from the back side of each gear tooth to the front side while some positive backlash is necessary to prevent localized gear tooth overloads excess backlash and clicking may sound annoying but won t hurt anything tight fitting gears will cause very noticeable whining which is definitely a more serious problem gear tooth and bearing damage can result from running zero backlash in this case a smaller cam gear or pinion gear
