 ===== Assembly ===== ===== Assembly =====
 +There is a small amount of pressure on the hydraulic lifter plunger holding the top retainer clip in place on a dry lifter. \\
 +It can be pushed down with your finger to install the clip. \\
 +But with a lifter half or more full of oil, it's harder to work the plunger with your fingers as the pressure behind the plunger is greater. \\
 +In fact, it's nearly impossible to assemble a lifter completely full of oil. \\
 +If you install the lifter into a holder, that frees up both hands and gives better leverage on the plunger. \\
 +The holder below is fabbed from a steel sheet and a welded bushing to hold the lifter. \\
 +A 2x4 block of wood with a 1" hole drilled into it can also be used to hold the lifter. \\
 +
 +Below is a fabbed steel holder. \\
 +The block is used to press the plunger down. A spare pushrod or screwdriver can also be used to depress the plunger.
