The MK1 Motorsport 1JZ / 2JZ Front Main Seal Installer is a purpose-built service tool designed to simplify front crankshaft seal installation on Toyota JZ engines. Whether you're performing maintenance on your own JZ-powered vehicle or regularly servicing 1JZ and 2JZ engines, this tool helps seat the front main seal in a controlled and repeatable manner.

Manufactured using FDM 3D printing with high-infill ASA plastic, the installer is designed for repeated use. Its application-specific shape allows the factory crankshaft bolt to be used to press the seal into position, while an alternative installation method allows the tool to be used with a rubber mallet.

Designed for 1JZ & 2JZ Engines: Purpose-built for front main crankshaft seal installation on compatible Toyota 1JZ and 2JZ engines.

Controlled Seal Installation: Helps keep the front main seal properly positioned while it is seated into the oil pump housing.

Two Installation Methods: Can be used with the factory crankshaft bolt for controlled installation or with a rubber mallet using the alternative method described below.

High-Infill ASA Construction: FDM 3D printed from high-infill ASA plastic for durability and repeated service use.

Application-Specific Service Tool: Designed specifically to make JZ front crankshaft seal replacement more straightforward and repeatable.

Designed & Fabricated in the USA: MK1 Motorsport designs and manufactures the tool in the United States.

  • Follow the seal manufacturer's lubrication and installation requirements.
  • Keep the seal centered and install it evenly to help prevent seal damage or improper seating.

Why Choose MK1 Motorsport?

The MK1 Motorsport Front Main Seal Installer is designed specifically around one of the more involved maintenance jobs on Toyota JZ engines. Rather than improvising a driver or attempting to seat the seal unevenly, the tool provides an application-specific surface for controlled installation.

Its high-infill ASA construction and reusable design make it a useful addition to the toolbox for JZ owners, engine builders, and technicians who regularly service 1JZ and 2JZ engines.
