Easy to follow step by step guide on how to replace or remove an automotive engine flywheel, though appearances may vary, the process is the same for most manual transmission rear wheel drive vehicles.
Difficulty Level - 7
Tools and Supplies Needed
Begin with the vehicle lifted enough to access the transmission while using jack stands for safety, wear protective eye wear and gloves.
Step 1 - Start by identifying the flywheel once the transmission and clutch have been removed.
Please visit our manual transmission removal guide for further instructions.
Please visit our clutch removal guide for further instructions.
Step 2 - Remove all flywheel mounting bolts, this can be difficult if
the flywheel turns while removing, have a helper wear gardening gloves and hold
it as you position the ratchet or wrench outward to minimize spin, or use an impact
wrench or flywheel holding tool (not shown).
Step 3 - Using a breaker bar, gently wedge it behind the flywheel and
in between the engine block, while grasping the flywheel firmly jar the flywheel
loose from the engine. (Note: The flywheel is heavy, so be ready.)
Step 4 - Once the flywheel has been removed, inspect the rear of the engine
including the rear crankshaft main seal and freeze plugs (if any).
Step 5 - Inspect the flywheel's condition, hard spots are an indication
of extreme use, if large cracks are present the flywheel will need replacement and
will not be eligible for resurfacing.
Step 6 - Once receiving a resurfaced or new flywheel, use carburetor cleaner
to clean the clutch surface thoroughly. (Note: Most automotive machine shops resurface
flywheels.)
Step 7 - Gently mount the flywheel onto the crankshaft, install the mounting
bolts by hand, (Note: Flywheel bolt pattern one only line up one direction to avoid
improper installation).
