{{Note1}}If trying to repair a bad lifter and the lifter's inner bore is OK but the plunger is found to be unrepairable, replace the plunger assembly from another identical lifter and reuse the lifter body, then replace the lifter back on the same lobe it came from. | {{Note1}}If trying to repair a bad lifter and the lifter's inner bore is OK but the plunger is found to be unrepairable, replace the plunger assembly from another identical lifter and reuse the lifter body, then replace the lifter back on the same lobe it came from. | ||

The plunger OD is matched to the lifter body ID; the close tolerances are required to give the correct amount of bleed down. For that reason, there is a chance you might need to go through more than one lifter to find a good match to the old plunger OD. The MAIN thing is that the plunger not be too tight. Slightly loose will still perform OK, although there's a chance there could be some slight tapping at idle. But if the lifter and cam cannot for whatever reason be replaced as a set, this is STILL preferable to putting a new lifter on a used cam. |
