Step 1
Before actual disassembly is started, turn
pump upside down and drain all liquid
trapped in the pump into a suitable
container. Be sure to use proper caution if
liquid is corrosive or toxic. Mark each liquid
chamber to its respective air chamber for
easy alignment during reassembly.
Step 2
Using a 3/16" hex-head wrench, loosen
the four manifold bolts. Remove the top
and bottom manifolds.
Step 3
Inspect both manifolds, manifold O-rings,
and valve balls. If swelling, cracking or
other damage is apparent, these parts
must be replaced with genuine Wilden
parts.
