The Sealing Gasket Set with OEM number 8-85670-040-0 is an ISUZU genuine sealing repair kit (ISUZU MOTORS LIMITED, JAPAN), figure number 134-442. Based on the physical appearance, the kit contains multiple O-rings of various sizes and shaped rubber seals for consolidated replacement and preventive maintenance of seals at a specific engine or transmission location. Supplying them as a set ensures all related sealing points are renewed at once, eliminating the risk of missed seals and repeat labor.
O-rings and rubber seals are fundamental elements for static and dynamic sealing in hydraulic, lubrication, and cooling systems. They fill the microscopic irregularities of mating surfaces through elastic deformation, maintaining a seal under pressure, temperature, and media (engine oil, coolant, hydraulic fluid). The shaped rubber component in the 8-85670-040-0 kit (the thick, perforated piece shown) may provide a formed seal for a specific cavity or interface.
Such sealing kits are commonly found on ISUZU engines at locations such as the oil cooler, timing gear case, injection pump mounting, transmission valve body, or oil pan — areas that require multiple sealing points. Because no public application list is available, the specific installation location must be verified by VIN.
Replace the seals when any of these symptoms appear:
- Visible oil or coolant seepage at mating surfaces — hardened, flattened, or cracked O-rings have lost sealing capability.
- Permanent deformation or loss of elasticity in O-rings — aged rubber cannot rebound to fill the gap.
- Visible cracks, cuts, or swelling on seals — caused by incompatible media or prolonged high temperature.
- O-rings stuck in the groove and difficult to remove during disassembly — rubber has degraded and bonded.

Because no detailed application list for 8-85670-040-0 is available in public databases, this kit cannot be matched by model name or engine code alone. Fitment must be confirmed by one of the following:
- VIN Verification (Preferred) — Provide the vehicle VIN for an ISUZU global EPC query to confirm applicability and installation location.
- Original Component Photo — Provide a photo of the removed part (with label/number) or the installation location.
- Engine/Transmission Model + Year — As supplementary information to narrow the verification scope.
Based on the ISUZU numbering system and the general usage of figure number 134-442, this sealing kit may be used at a specific sealing location on the following platforms:
| Platform / Series | Possible Engine/System | Verification Required |
|---|---|---|
| ISUZU NKR / NPR / NQR | 4JB1 / 4HF1 / 4HE1 / 4HK1 | VIN required |
| ISUZU ELF / 700P | 4HK1 / 6HK1 | VIN required |
| ISUZU Transmission/Clutch | Specific valve body or interface | VIN required |
- Do not guess fitment based on model year or experience. The installation location and internal component specifications of a sealing kit must be confirmed by VIN.
- Thoroughly clean the seal groove and mating surface before installation.
- Use dedicated tools to remove old O-rings; never score the groove with a blade or screwdriver.
- Apply a compatible lubricant during installation (clean engine oil for oil systems; dedicated rubber grease for brake/clutch systems).
- Single-use seals must never be reused.
- For right-hand drive (RHD) vehicles, verify installation orientation. Refer to the ISUZU workshop manual.
