Step 12. Attach the coupling on the end of the shaft
and insert hairspring cotter pin.
Step 12
Step 13. Inspect cover and housing at machined
surfaces (ame paths) for any signs of
damage. If surfaces are damaged the unit
must be replaced as this is part of the (ame
proof/explosion proof) protection. Apply a
light coating of multi-purpose synthetic
grease to the cover o-ring and ame path
joint before reattaching the cover to the
housing. This helps maintain a water-tight
seal and provides additional corrosion
protection to the ame path. TechnipFMC
synthetic grease P/N 644886401 is
recommended. Apply a nickel based
anti-size lubricant to all cover fasteners.
TechnipFMC P/N 646002401 is recommended.
Step 13
Step 14. Close the cover and tighten the eight cap
screws around the perimeter of the cover
using the sequence shown. The nal torque
should be 15 LB-FT / 180 LB-IN (20.3 Nm /
207.4 Kg. cm).
Step 14
Step 15. After tightening all cover bolts, check the
joint with a 0.0015" (0.038 mm) feeler
gauge all the way around the outer
perimeter of the enclosure. The feeler
gauge should not insert more than 0.125"
(3.2 mm) at any point. If it does, remove
the cover and recheck the cover joint for
any foreign objects, reassemble and check
again.
