Remove the nut (Item 1) [Figure 20-40-103] from the solenoid stem.
Installation: Tighten the nut to 53 in.-lb. (6 Nโขm) torque.
Remove the solenoid coil (Item 2) [Figure 20-40-103].
Remove the O-rings (Item 1) [Figure 20-40-104] from both ends of the solenoid coil.
Use an Ohm meter to measure the solenoid coil resistance.
The correct resistance for the coil is 9.79 ยฑ 0.29 ohm.
Remove the solenoid stem (Item 1) [Figure 20-40-105].
Installation: Lubricate the O-rings and tighten the stem to 20 – 24 ft.-lb. (27 – 33 Nโขm) torque.
Remove the O-rings (Item 1) and back-up rings (Item 2) [Figure 20-40-106] from the cartridge.
Clean all parts in solvent and dry with compressed air.
Inspect all parts for wear and replace any showing excessive wear.
NOTE: The screen (Item 3) [Figure 20-40-106] may be cleaned with solvent. If it is torn or worn it needs to be replaced.
Use only new O-rings and apply oil to all O-rings and back-up rings before installation.
Install new O-rings (Item 1) [Figure 20-40-104] & [Figure 20-40-106] and new back-up rings (Item 2 [Figure 20-40-106] on the solenoid stem.
