During scheduled maintenance of the NOV TDS-11SA Shot Pin Assembly 30151875, maintenance personnel should follow the manufacturer's procedures to inspect relevant components and identify signs of wear or damage.
Depending on the applicable inspection requirements, attention may be given to visible tooth damage, unusual wear patterns, looseness, or other abnormalities. If a gear requires replacement, the mating components and related assembly should also be checked as appropriate.
Correct part identification is particularly important when ordering replacement gears. Similar-looking components may differ in dimensions or design, so appearance alone is not sufficient to confirm compatibility. Always verify the part reference, assembly number, and equipment model before purchasing.
