Heavy equipment owners and mechanics, this complete overhaul kit is exactly what you need to rebuild your 3LD1 diesel engine! The kit includes everything for a full engine rebuild: full gasket set, 3 semi-finished cylinder liners (no flange), 3 pistons with pins and clips, ring sets for all pistons, connecting rod bushings, main bearings (STD size), rod bearings (STD), and thrust washers. The pistons are 83mm diameter x 80mm height in standard size, perfect for bringing your engine back to factory specifications. This kit fits Isuzu engines used in Sumitomo SH30, Hitachi EX29UE/EX30U/EX32UE/EX35U/EX36UE, Hanix H26B/H29A/H30A, IHI 35NX/35J/35N/38UJ, and Nagano NS25/NS30/NS35 excavators. The aftermarket parts are high-quality and designed for direct replacement, with a 12-month warranty for peace of mind. Proper installation ensures better compression, consistent combustion, reduced emissions, and prevents oil or coolant leaks that can cause engine failure. Before ordering, double-check your piston specifications and remember that all bearings are STD size - contact the seller if you need oversize bearings. The seller also offers other 3LD1 components if you need additional parts for your rebuild project. Reliable engine performance starts with quality rebuild components, and this kit delivers everything you need in one package!
