12. Lower ball onto wood blocks with the plates clear and remove the plates from the
ball. Spacer and lower thrust washer are now free. Retainer pins are a press fit in
bearing plates and should NOT be removed.
13. Remove from closures, four (4) seat retainer capscrews and bushings (if valve is so
equipped). Carefully pry out the seat ring assembly from both closures and remove
seat ring springs from the closures. Remove buttonhead grease fittings and ball
check valves from closures for inspection and cleaning.
14. Disassemble seat ring as follows: a. Remove seat gasket O-ring and U-cup (not
shown).

13.
Remove from closures, four (4) seat retainer capscrews
and bushings (if valve is so equipped.) Carefully pry
out the seat ring assembly from both closures and
remove seat ring springs from the closures.
Remove buttonhead grease fittings and ball check
valves from closures for inspection and cleaning.
14.
Disassemble seat ring as follows: a. Remove seat
gasket O-Ring and U-Cup (not shown).
a.On small valves, the U-Cup remains in the
closure when the seat assembly is removed.
b.
Remove lock pin by introducing screw driver
between inner and outer seat rings and pry pin
outward. Compress lockring inward by
introducing a punch-thru hole adjacent to pin and
progressively pry out lockring from it's groove.
c.
Separate inner ring from outer ring and remove
Seal O-Ring.
B. INSPECTION AND CLEANING
1.
Wipe off metal parts with soft cloth, using a
petroleum solvent, detergent, or cleaner. Replace
O-Rings and gasket.
2.
Inspect metal parts for damage or burrs on all
moving surfaces.
3.
Replace defective parts with only genuine 370D5
manufactured and supplied parts.
NOTE: O-Rings are made to stretch with a certain
tension around a metal shoulder. Any stretching or
swelling of O-Rings may cause cutting on reassembly.
Do not reuse O-Rings unless their dimensions are
carefully checked against new parts.
C. LUBRICATION
1.
DO NOT
lubricate the dry bearing plates or the
contact surfaces.
2.
For temperatures from -50°F to +225°F, lubricate
all moving contact metal surfaces with a low
temperature, high quality grease. Lubricate O-Rings
with heavy grease. (Marfak #3 or equal.)

3.
For temper10°F to +350°F, lubricate all
moving contact metal surfaces and O-Rings with
Bracote 622 wide temperature grease or equivalent.
D. REASSEMBLY
1. Place both closures on a clean, solid surface.
If flanged, be careful not to damage sealing surface.
2. a. Install check valve and buttonhead grease fittings
into sealant passages of closures.
b.
Lubricate threads with thread sealant.
c.
Fill sealant cavities, through the grease fittings,
with a low temperature, high quality, grease
until lubricant just appears in the seat ring recess.
This process serves to lubricate the check valves,
assuring pressure tightness.
3. Reassemble seat rings:
NOTE: A press will make the assembly of the inner
and outer seat rings easier. Contact Cameron for
more information.
a. Place Seal-O-Ring in inner seat ring and place
outer seat ring over inner ring, set the loose seat
rings in the press then press together.
