Item Nomenclature
C211 Sealing Compound, Corrosion Inhibitive
C247 Petroleum Wax (Preferred)
C245 Conductive Grease (Alternative)
C246 Conductive Oil (Alternative)
(1). Prepare the mating surfaces of aft
stop-clamp (8), end of jumper (4), and
aft crosstube (1) for an electrical bond
(ref. CSP-SPM, Section 20-50-00).
Petroleum Wax (C247)

(2). Apply petroleum wax (C247) or altern
atives to the mating surfaces of aft
crosstube (1) and aft stop-clamps (8).
Make sure countersunk washer
(11) is next to head of bolt (10)
before you install jumper (4). Incorrect as
sembly can cause electrical problems.
(3). Install aft stop-clamp (8) on aft

clamp (8).
(c). Torque nut (13) 70 to 90 in-lb (7.91
to 10.17 Nm) more than the run-on
torque (ref. CSP-SPM, Section
