SPECIAL NOTES:
(1) Lubricants: Molykote G paste, Teflon-base pipe dope, graphite-base grease, or
similar lubricants. Lube first 2 threads only. Do not lube bearing surface.
(2) Torque on bolts is accomplished in 3 or 4 steps. Tighten UNIFORMLY.
(3) For DP units marked as 1850 PSI (12.7 MPa) and 1500 PSI (10.3 MPa)
originally supplied with 12- point head bolts, Cameron has re-rated these lower
pressure DPUs to 2000 PSI (13.7 MPa). Apply the parts and use the torque
values for the 2000 PSI model (Table 4-3).
(4) For DP units marked as 1500 PSI (10.3 MPa) originally supplied with 6-point
head bolts, use a standard B7 alloy steel bolt that is suitable only for
applications where the application environment is not deemed to be sour.
WIth the exception of 0199-0085C bolts, apply the parts and use the torque
values for the 2000 PSI model (Table 4-3).
(5) If originally supplied with unit, re-install the "Do Not Reuse Bolts" and "NACE"
product tags.
