Preventative Maintenance: Inspecting Internal Components
BODY (36):
Visually inspect the O-ring groove area beneath the seal. This is a critical area. The body will need to be
replaced if any indication of wear or damage is present. Visually inspect the fluid discharge surfaces for erosion
or corrosion. Some wear in this area is expected. Any damage to this surface exceeding .100” renders the part
unusable. Thoroughly inspect the internal threads; threads must be clean, free of galling or damage. Visually
inspect the flange seal surface for erosion or corrosion. Damage to this area will allow fluid to leak past the
flange during the relieving function. The body should be replaced if any sign of damage is present.
