REPAIR PROCEDURES
8. Remove pressure gauges with a 9/16-in. wrench fromthe cylinder pressure gauge port of the body.
9. If inlet nut and/or nipple are damaged, remove nippleusing an 11/16-in. deep-wall six point socket or open-end wrench and discard the damaged part(s).
NOTE: If nipple is difficult to loosen, try placing bodyin hot water for a few minutes to soften theLoctite sealant and then try to remove thenipple again while the body is still hot.
10.Remove inlet filter inside the nipple with a No. 1 “Ezy-Out” or a long No. 6 wood screw and discard filter.
11. If outlet connection is damaged, remove with a 5/8-in. wrench and discard.
CLEANINGAll parts which were not discarded during disassemblyshould be cleaned for oxygen service, even if the regu-lator is made for fuel gas or inert gas service. CleaningCompound No. 81 (P/N 73585081) is a suitable cleaningsolution. For brighter finish of brass parts, Bright-DipCompound No. 70 (P/N 73485070) may be used. Thesecompounds are available in 20 lb. containers. The solu-tions should be made up as directed on the containers.
If inlet nipple and/or outlet connection were removed,retap the 1/4-in. NPT threads in body to remove anyresidual Loctite sealant. Blow out chips with low pressuredry nitrogen. Threads must be clean. Make sure no chipsor foreign material gets into valve cavity.
REASSEMBLINGDuring reassembly, the following procedures shouldalways be observed:
1. When replacing inlet nipple or outlet connection.Loctite Grade “#242” Compound (P/N 73585435)should be used as follows:
REPAIR PROCEDURES
TOOLSIn addition to standard tools (see Section H-1; Item 4),the following are also recommended for repairing the R-36 family single-stage regulators:
Nesting Fixture, P/N 5220128Cap Spanner Wrench, P/N 5230146O-Ring Insertion Tool, P/N 5220136Spanner Wrench (RBO Adaptor) -(R-36-75-540), P/N 5250149
DISASSEMBLINGIn the parts illustrations (starting with Item 300) parts thatshould be replaced by new parts are indicated by asquare about the item number. When disassembling aregulator, examine all other parts as they are removed.If a part is damaged, it should be replaced.
To disassemble an R-36 regulator, proceed as follows:
1. Place regulator in nesting fixture (5220128) thatshould be clamped in a vise.
2. Remove pressure-adjusting screw.3. Remove cap using spanner wrench.4. Remove spring, spring washer, diaphragm slip ring
and diaphragm assembly. Discard the diaphragmassembly.
5. Remove valve seat screw with a 3/4-in. socket wrench.Remove and discard the O-ring on valve screw.Examine the seating surface about the orifice insidethe valve seat screw. If nicked or scored, discard theseat screw.
NOTE: Replacement seat screw includes O-ring.
6. Remove and discard seat-and-stem and valve clos-ing spring.
7. Remove safety release valve cap (if equipped) with a3/8-in. wrench. Remove and discard the disk and twowashers.

REPAIR PROCEDURES
a. Thread should be clean - free of grease and oil.b. Apply one drop of Loctite on the second thread
from the lead end of the male pipe threads.c. Rotate the part about 900 to encourage the
liquid compound to flow around the threads. DoNOT allow the liquid to flow to the lead end ofthe threads.
d. Assemble hand tight and then tighten with atorque wrench to 500 in.-lbs.
2. Starting from the second thread, wrap a single turn of1/4-in. wide Teflon tape around the pipe threads ofeach gauge; assemble the gauges to the propergauge port in the body; and then tighten each gaugewith a wrench until snug and properly positioned.
3. Blow out valve seat cavity in body with low pressuredry nitrogen so that all chips are removed.
4. Tap new filter into inlet nipple with a clean 1/4-in.diam. metal rod.
5. If regulator is equipped with a safety release disk,install new disk between two new washers (smoothside against the disk) in the body. Make sure Screen(17726) is in place.Assemble and tighten safetyrelease cap with a torque wrench to 20 in.-lbs.
6. Place new valve closing spring in the body and thenplace new stem-and seat on top of spring.
7. Install O-ring between the hex and threads of valveseat screw using O-ring insertion tool (5220136).Without the tool, O-ring may be damaged by thethreads of the seat screw.
8. Install valve seat screw so that stem-seat pin pro-trude through the orifice. Push down to engagethreads and then tighten seat screw with torquewrench to 300 in.-lbs. Push down on stem to makesure it moves freely.
9. Place new diaphragm assembly, slip ring, pressure-adjusting spring, and spring washer in position.
10.Assemble cap and tighten to 120 in.-lbs. usingspanner wrench (5230146).
11. Install pressure-adjusting screw turning it in onlyenough to touch the spring washer.
NOTE: If trim screw was used and removed, installin pressure-adjusting screw only a few turns.Adjustment of trim screw is made during thetesting procedures.
TESTINGAll remanufactured regulators must be tested as de-scribed in Section H-1, Item 2 using specifications inItem 2 of this section.
If trim screw was used and removed from pressure-adjusting screw, then proceed as follows:
1. With inlet gas supply set at specified pressure andwith a No. 53 orifice connected to the outlet ofregulator as described in the Section H-1, Item 2,remove trim screw, open test shutoff valve, and turnin the pressure-adjusting screw all the way. Gasshould be flowing out of the No. 53 orifice.
2. Apply one or two drops of Loctite-Super Bonder No.495 (71200434) about midway on the threads of thetrim screw and then install in pressure-adjustingscrew. Turn in trim screw until you obtain a readingslightly above the specified minimum delivery pres-sure.
3. Close test shutoff valve. Wait at least two minutesto allow adhesive on trim screw to set before turningpressure-adjusting screw. Check for leakage at alljoints while waiting.
4. Open test shutoff and proceed to the “jump-and-creep” test.

TEST SPECIFICATIONS
(1) Gas (nitrogen) flow is through a No. 53 (0.0595-in. diam.) drilled spud, P/N 5220032.(2) With pressure-adjusting screw turned in all the way and with no flow from outlet,
delivery pressure reading should not exceed 28 psi.(3) The R-36-CF-580 is equipped with flow gauge calibrated in cubic feet/hour (cfh)
when used with spud P/N 150Z06 (installed in outlet connection of regulator).(4) Use No. 63 (0.037-in. diam.) drilled spud (P/N 5220062) instead of No. 53 drilled
spud. Adjust delivery pressure to 50 psig with inlet pressure of 1300 psig, withflowmeter valve wide open, and with nitrogen flowing through the No. 63 drilled spudattached to the outlet of flowmeter. At this setting, top of ball float in flowmeter shouldread between 56 and 64 on the argon scale.
