EL-740 Air Compressor Unloader Reassembly

1. Lubricate the bores in the unloader body with Dow-Corning #33 Lubricant.

2. Insert new expander springs into new diaphragm cups. Place the diaphragm cups into the bores of the unloader body with the expander springs facing the inside of the body.

3. Insert the valve discs and bushings into the unloader bores with the valve disc positioned next to the diaphragm cups.

NOTE: Some unloader assemblies use snap rings to retain the bushings in the unloader body. On this style assembly a pair of snap ring pliers will be required to install the snap rings.
