Product Description
OEM Nozzle Holder Seal S2307-41070 Injector Sleeve For HINO J05E J05ETA Engine Kobelco SK200-8 SK250-8 SK260-8 Excavator
High-quality rubber seal with 6-month warranty, designed for HINO J05E and J05ETA diesel engines in Kobelco and Sany excavators.
Product Overview
The Nozzle Holder Seal (Injector Sleeve) with OEM number S2307-41070 is a verified OEM-grade direct replacement for HINO J05E diesel engines. This precision-engineered rubber seal is a critical component of the fuel injection system, providing a gas-tight and coolant-tight seal between the injector and cylinder head.
Naming Note: While some suppliers list part number S2307-41070 under the generic term "Cover Gasket", this component is correctly identified in HINO/TOYOTA parts catalogs as a "SEAL, NOZZLE HOLDER" - the rubber seal that sits at the base of the fuel injector where it interfaces with the cylinder head.
Key Features:
- OEM Specification - Verified by HINO OEM part number S2307-41070 and cross-references S23074-1070, 23681-78030, and 23074-1011
- Precision Fitment - Designed specifically for HINO J05E and J05ETA diesel engines
- Proven Durability - Manufactured from high-quality rubber material to withstand high temperatures and continuous engine vibration
- 6-Month Warranty - Backed by warranty for peace of mind
- Wholesale Supply - Available for bulk orders with competitive factory pricing (5,000 pcs/day capacity)
Failure Symptoms
If your nozzle holder seal is failing, you may experience one or more of the following symptoms:
- Coolant Leakage into Combustion Chamber: White smoke from exhaust and unexplained coolant loss
- Combustion Gas Leakage: Ticking or chuffing noise from injector area with black soot deposits
- Hard Starting / Rough Idle: Difficulty starting engine or rough idling
- Loss of Engine Power: Reduced combustion efficiency
- Fuel Dilution of Engine Oil: Fuel mixing with engine oil
- Visible Cracking or Hardening: Rubber seal appears cracked, brittle, or hardened
Warning: A failing nozzle holder seal is a serious engine integrity risk that can lead to coolant contamination, fuel dilution of engine oil, and potential cylinder head damage. Prompt replacement is essential.
