FAQ

Q: How do I verify that this 4JB1 cylinder liner kit is the correct part for my engine?
A: The most accurate way to verify fitment is to compare the part number (1855760840) against your engine’s service manual or the part number stamped on your existing liner. Additionally, measure the inner diameter (bore) and outer diameter (flange) of your old liner. The 4JB1 engine typically has a specific bore size, but variations exist. If you are unsure, contact us with your engine serial number for verification.

Q: What is included in this “Piston Liner Kit”? Does it include piston rings or a piston itself?
A: This specific kit (part number 1855760840) is primarily a “Cylinder Liner Kit” or “Piston Liner Kit.” It includes the cylinder liner (sleeve) for one cylinder. It typically does not include the piston, piston rings, or wrist pin. For a complete engine rebuild, you will likely need to purchase a separate piston and ring set for the 4JB1 engine. Please review the product specifications carefully.

Q: What are the signs that my 4JB1 engine needs new cylinder liners?
A: Common symptoms of worn cylinder liners include excessive oil consumption (blue smoke from the exhaust), loss of engine power and compression, difficulty starting, and a knocking sound from the lower engine block. If a compression test reveals low or uneven cylinder pressure, and the engine has high operating hours, worn liners are a likely cause. Replacing them with this kit will restore proper sealing and performance.
