Sherwood SRB3600 manual Assembly of Second Stage

16.If you need to replace certain parts of the lever assembly (stem, spring, lever, etc.), you can do this by temporarily screwing the orifice housing 13 with the orifice 10 back onto the lever support and assembly (without the plastic case). With these parts screwed together, the locking nut 29 can be removed without all of the components springing apart. Remove the old part, install the new part, and re-tighten the locking nut 29 .

17.Hold the orifice housing 13 in one hand. Temporarily install the adjusting knob 29 and use it to turn the orifice clockwise until it comes out of the orifice housing. Remove and discard the

O-rings on the orifice 8 9 and the orifice housing 11 12 .

18.Grasp the oval exhaust valve 16 with your fingers and pull first one and then the other locking nipple out of the case.

19.Rinse all plastic and silicone parts in clean fresh water, and then blow the parts dry with compressed air.

20.Inspect the case 17 for any cracks. Look particularly closely at the area where the orifice housing and the lever support clamp down. Replace the case if you find any cracks. Squeeze marks and lines caused by compression of the case between the lever support and orifice housing are not a reason for changing the case.

21.Inspect the exhaust valve and the diaphragm for any tears or pin holes by stretching them gently as you hold them up to a light. If you are repeatedly tearing diaphragms while inspecting, you are applying too much force.

22.Inspect the orifice 10 for any nicks, scratches, or corrosion. Polish out any corrosion or minor scratches using a fine-grit rubberized polishing stick or a clean new pencil eraser. Remember not to apply too much pressure when rotating the polishing stick. Check frequently to see when the corrosion or scratch is gone and stop at that point. Blow all dust and debris out of the orifice housing using clean compressed air.

23.Inspect all O-ring grooves in the metal parts of the second stage. Clean all O-ring grooves with a lint-free cloth.

NOTE: Prior to this point, you should have cleaned and inspected all parts, following proper service procedures. Do not continue until this has been done.

6.3ASSEMBLY OF SECOND STAGE

1Install the exhaust valve 16 into the case by inserting the two nipples into the small holes from the outside of the case. Reach inside the case and pull each nipple firmly with the fingers until you hear or feel it "click" into place. Inspect the exhaust valve to see that it is properly seated.

2.Install the lever support 26 and assembly into the case, setting it firmly between the guide ribs in the case.

3.Lubricate and install new O-rings 8 9 from the annual service kit onto the orifice 10 Install the orifice back into the orifice housing 13 using your fingertip. Use the ad usting knob 4 to turn the orifice counter-clockwise until it stops.

4.Apply a drop of mild thread locker (such as Locktite 242® or equivalent) to the threads of the lever support 26 .
