3. Remove the bonnet screws (4), bonnet (3), upper spring rest (5), spring (6), lower spring rest (7), dia-
phragm (8), and diaphragm protector (9).

Reassembly
To reassemble the fluid regulator, follow these steps:
1. Reassemble parts in reverse order of disassembly.

“T” handle (1).
3. Torque the bonnet screws (4) to 60 inch-pounds.
