(Pump disassembly, continued.)
To continue pump disassembly, you will need the following tools:
. (2) 3/4'' Open end wrench
. (1) 1'' Combination wrench
. (1) Adjustable wrench
. (1) Ratchet with extension
. (1) 9/16'' Socket
. (1) 7/16'' Socket
6. To remove diaphragms, place a 3/4'' open end wrench on each of the outer pistons and
loosen. This will allow the diaphragms, inner pistons (2/5), outer pistons (2/6), and shaft (2/4)
to be removed. Make sure to set aside the piston inner washers (2/7) for reassembly. Use the
7/16'' socket, ratchet and extension to separate the diaphragms from the outer pistons by
removing the nuts (2/10).
7. Remove both air chambers (2/3) from the center block (1/1) by removing the bolts (1/12)
using the 9/16'' socket, ratchet and extension.
Note: Once the air chambers are removed, you must replace both block gaskets (1/2)
before reassembling your pump. Block gaskets are intended ONLY for one time
use/compression, and should not be reused. Refer to section 8.0 on Spare Parts to order
block gaskets.
8. Remove the center block gaskets. Inspect the center block for any debris. Clean if necessary.
Use the 1'' wrench to remove the air inlet cap (1/11). Remove the air inlet filter (1/6) to inspect
for any debris. If dirty or discolored, replace the air inlet filter. If the muffler (1/7) is dirty or
discolored, replace the muffler. Use the adjustable wrench to remove the muffler. Do not reuse
dirty/discolored air inlet filters or mufflers, as this may result in poor performance of your
pump. Refer to Section 8.0 on Spare Parts.
9. Refer to Sections 5.1 and 5.2 for instructions on how to replace Assemblies A, B and C.
