6D22 Full Gasket Kit ME999665 ME999370 For Mitsubishi Engine Parts
This Mitsubishi 6D22 overhaul rebuild kit (OE No. ME999665) is a professional-grade heavy-duty replacement set engineered specifically for Mitsubishi 6D22 diesel engine variants (including 6D22T, 6D22T1, 6D22T2, 6D22T3, 6D22-Na) — the 11-liter power core for mid-to-large construction machinery, heavy-duty trucks, and industrial equipment. Every component is precision-machined to match original equipment manufacturer (OEM) specifications, ensuring seamless fitment, exceptional durability under extreme load and continuous-operation conditions, and restored peak engine performance.
As a critical solution for Mitsubishi Engine Parts replacement, this kit undergoes rigorous quality testing (material composition verification, dimensional accuracy checks, and high-pressure sealing validation) to meet industrial standards, making it the ideal choice for major overhaul, full engine rebuild, or critical maintenance in construction, mining, and heavy industrial power applications.

- Full heavy-duty gasket set (MLS cylinder head gasket, metal-clad intake/exhaust gaskets, oil pan gasket, valve cover gasket, timing cover gasket, crankshaft front/rear seals [OE BZ1335E/AZ8854P], camshaft seals, etc.)
- 6x High-strength forged aluminum alloy pistons (STD size) + piston pins + locking snap rings
- 6x Piston ring sets (3-piece: top compression ring, second compression ring, oil control ring — wear-resistant alloy steel, OE ME052889/ME995467 compatible)
- 6x Cylinder liners/sleeves (cast iron construction, semi-finished for precise fitting)
- Full set main bearings (precision-ground tri-metal construction with anti-fatigue design)
- Full set connecting rod bearings (anti-wear alloy material with micro-polished surface)
- Thrust washers (engineered for proper crankshaft alignment and reduced end-play)
- 6x Intake valves + 6x exhaust valves (high-tensile steel with heat-resistant coating)
- 12x Valve guides + 12x high-temperature valve seals + valve seats + cylinder head bolts (as applicable)
- Piston pin bushings, camshaft bushings, and timing system accessories (per 6D22 variant requirements)
- OE-Matched Precision: Every component aligns with Mitsubishi 6D22 OEM specifications (core OE No. ME999665), ensuring perfect fit with turbocharged variants (6D22T/6D22T2) and seamless integration with existing Mitsubishi Engine Parts.
- Heavy-Duty Material Selection: Forged pistons, multi-layer steel (MLS) gaskets, and wear-resistant bearings withstand extreme pressure (up to 2300 psi) and high temperatures — ideal for Kato NK-800 cranes, Kobelco SK400 excavators, and Mitsubishi Fuso Super Great trucks operating in harsh environments.
- Comprehensive 6-Cylinder Coverage: Tailored for 6D22's inline 6-cylinder configuration, including 6 sets of pistons, liners, and valve components to cover full engine rebuild needs, eliminating separate purchases.
- Superior Sealing Performance: Premium gaskets and oil seals (including OE-matched crankshaft seals) prevent oil leaks, coolant loss, and combustion gas blow-by, reducing heat loss and improving engine efficiency in continuous-operation scenarios.
- Performance Restoration: Restores 96% of original engine power (up to 224hp for 6D22T3 variants), reduces fuel consumption by 7-9%, and minimizes noise/vibration — returning the 6D22 engine to like-new operational stability.
- Application-Specific Design: Optimized for turbocharged and naturally aspirated variants, meeting the high-torque demands of construction machinery, long-haul trucks, and industrial power units.
- Mitsubishi 6D22 diesel engine variants: 6D22T, 6D22T1, 6D22T2, 6D22T3, 6D22-Na
- Construction machinery: Kato NK-800/NK-1200 mobile cranes, Kobelco SK400/SK450 excavators, Sumitomo S430 equipment
- Commercial vehicles: Mitsubishi Fuso Super Great (FP/FV/FS series) trucks, Hyundai 11-ton cargo trucks, Nissan UD 1800/2000 series
- Industrial power units: Heavy-duty generators, air compressors, and marine auxiliary engines running on 6D22 engines
- Mining and road-building machinery requiring reliable mid-to-high power output
- Genuine OE Compatibility: Engineered to match core OE No. ME999665 and compatible with secondary OE numbers ME999370/ME999609/ME052889, ensuring direct replacement for original Mitsubishi 6D22 parts.
- Strict Quality Control: Every kit undergoes 100% inspection before shipment, including cylinder liner flatness testing, piston ring elasticity verification, and gasket high-pressure sealing validation.
- Turbo Variant Optimization: Designed to support 6D22's turbocharged configurations (6D22T/6D22T3), with components that withstand boosted pressure and enhanced heat output from TD08H turbochargers.
- Stable Inventory: Large stock levels to fulfill urgent orders for construction and transportation projects, with fast worldwide shipping.
