Toyota Land Cruiser FJ40 · Toyota 2F · 1975–1984
What is the stock Toyota 2F cylinder bore?
The factory standard cylinder-bore range for the Toyota 2F engine, with the exact manual page and wear-limit context.
Short answer
The Toyota 2F Engine Repair Manual lists the standard cylinder-bore diameter as 94.00–94.05 mm (3.7008–3.7027 in). The same factory specification page lists a cylinder-bore wear limit of 0.2 mm (0.008 in).
Tools and setup
Before you start
- Confirm that the installed engine is a Toyota 2F before using the specification.
Verification checks
- Measure each bore at the locations and directions specified by the factory inspection procedure, not at a single convenient point.
- Treat the standard-bore range and the wear limit as different specifications.
Common mistakes
- Using an oversize piston dimension as though it were the original standard bore.
- Assuming a 1975-or-later FJ40 still has its original 2F engine.
