Where is flywheel on an engine

As you shift gears, your engine revs and you can tell that it did not shift gears. Your car likely has slipped back to the gear you tried to advance from, or in this case, slipped back to second gear.

Unfortunately, slipping gears is also a tell-tale sign of clutch trouble. As such, if you experience slipping gears, you need to look for other signs so you can determine if the clutch or flywheel is going bad. When you step on your clutch, you expect to feel a smooth pedal that pushes down as you press upon it. If your flywheel is going bad, a smooth pedal is not what you will feel.

You may feel vibration as soon as you place your foot on the clutch or when you press down on the clutch. The vibration tends to get stronger as you push on or engage the clutch pedal.

A burning scent that is prominent as you shift in or out of gears can indicate both clutch problems and flywheel problems. The smell will be noticeable in the cabin of your car or truck. If you roll down your window or pull over and lift up your hood, you will likely not notice a scent. This is a key indicator that the problem is with the clutch or flywheel versus the engine.

Thinking about what the burning smell smells like can help you determine if you may have a bad clutch or a failing flywheel. If you smell a burning scent that smells like burning rubber or an electrical fire, you likely have clutch issues. If the burning scent smells more like burning toast, your flywheel is likely the culprit. Clutch chattering occurs when you release the clutch to switch gears. Instead of shifting smoothly, you feel stuttering or vibrating, also called chattering.

When your clutch chatters, you may feel like your car will stall while you switch gears - or your car may actually stall. The clutch is more likely to chatter when you start to drive from a complete stop, such as after stopping at a red light or stop sign.

However, it can occur any time you switch gears. Clutch chattering can be from many clutch issues, including problems with the clutch release or the bearings.

There are marks on the rim or end of the flywheel that allow you to set the piston of the first cylinder to top dead center.

The crankshaft assembly with the flywheel and clutch is subject to dynamic and static balancing. So that unbalanced inertia forces do not cause engine vibration and accelerate wear of the main bearings. Typically, a flywheel is attach to the crankshaft flange with bolts that are heat treat or ground.

The castellate nuts screw onto these bolts are thoroughly split. The mold from the mounting holes on the flywheel and in the flange is circumferentially offset by several degrees, which ensures the exact connection of the flywheel and the crankshaft if for some reason they were disassembled.
