The ATC ZTSE4512 Oil Gallery Plug Driver is the professional tool for precise installation and removal of oil gallery plugs on Navistar International diesel engines—applies controlled, even force to prevent thread stripping, plug face damage, uneven seating, or oil leaks during rebuilds and oil system service.

The Expensive Risks of Improper Oil Gallery Plug Service on Navistar Engines

Using sockets, punches, or improvised drivers on oil gallery plugs often strips threads, damages plug faces, causes cross-threading, or results in leaks—leading to low oil pressure, bearing starvation, or full engine damage.

• Stripped / cross-threaded plug – $200–$800 plug + thread repair
• Oil leak at gallery – $800–$3,000 cleanup, bearings & contamination fix
• Low oil pressure / starvation – $2,000–$10,000 bearing / crank damage
• Engine seizure or rebuild – $8,000–$25,000+ full overhaul
• Downtime & lost revenue – 4–15 days ($800–$2,500/day)
• Rework labor — Extra 10–40 hours at $150–$350/hr
