Why Replace Your Flywheel Bolts?

Reasons for fitting new flywheel bolts include:
- Installing a replacement or upgraded flywheel
- Replacing a worn clutch assembly
- Completing an engine rebuild

Important Installation Information
Flywheel mounting bolts are critical fasteners and must be installed correctly.
Before installation, confirm the bolt part number, quantity, thread engagement and compatibility with the crankshaft and flywheel.
Inspect the crankshaft threads and flywheel mounting surfaces for damage or contamination.
Follow the applicable Nissan factory workshop procedure for tightening sequence, torque specification and any required thread treatment.
Do not assume that tightening specifications are identical across all RB engines or aftermarket flywheel combinations.
