Do you have to resurface flywheel when changing clutch?
When it comes to engine and transmission work, it can be a pain to have to do anything twice. Labor costs are usually the most expensive part of any intensive job, such as changing a clutch, so its recommended to get the flywheel resurfaced every time the clutch is replaced.
Do you have to resurface a flywheel before replacing a clutch?
Of course, if the surface of the flywheel is flat and free from defects, there is no need to resurface it. But if it is not in like-new condition, the flywheel should be resurfaced before the new clutch is installed. If a worn flywheel is not resurfaced, the replacement clutch won’t last.
When to do a flywheel inspection and resurfacing?
Flywheel Inspection & Resurfacing. Of course, if the surface of the flywheel is flat and free from defects, there is no need to resurface it. But if it is not in like-new condition, the flywheel should be resurfaced before the new clutch is installed. If a worn flywheel is not resurfaced, the replacement clutch won’t last.
What causes a crack in a flywheel clutch?
Additionally, cracked flywheels also mean that the shift mechanisms could wear out quickly. Is the part “cupped” or unevenly worn? “Cupping” is caused by the interior surface of the part being worn down by constant contact with the clutch.
What causes a flywheel to have uneven wear?
“Cupping” is caused by the interior surface of the part being worn down by constant contact with the clutch. Uneven wear indicates another problem, such as a misaligned part or one that has too much “play” between it and the contact point.
Of course, if the surface of the flywheel is flat and free from defects, there is no need to resurface it. But if it is not in like-new condition, the flywheel should be resurfaced before the new clutch is installed. If a worn flywheel is not resurfaced, the replacement clutch won’t last.
What should I do if my flywheel is unbalanced?
If a flywheel is unbalanced, it may vibrate the whole powertrain even while the clutch is engaged. If you recently replaced the clutch, flywheel, or pressure plate, make sure you torqued all bolts to spec and applied thread locker if it was called for in the factory service manual.
Is the clutch disc mounted to the flywheel?
The clutch disc is mounted to the flywheel via the pressure plate. If the flywheel has mild wear, then it can most likely be resurfaced, but if it shows a higher level of wear including thermal cracks, it will require replacement. With higher performance clutch kits, lightweight aluminum flywheels are often included.
When do I need to change the flywheel?
You will rarely need to replace the flywheel, but the flywheel should be resurfaced whenever the clutch disc is replaced in a high-mileage car, and that can be easily done when the clutch assembly has been removed.
