Can a flywheel cause damage to a clutch plate?

So I recently had my flywheel machined from a 3rd party and bought a new clutch. After driving the car I noticed a shudder. Took it back to mechanic. Mechanic said flywheel has a high spot. Person who skimmed flywheel said that the mechanics must have bent the clutch plate. I am wondering if the warped flywheel maybe caused the new clutch plate to bend? There is a 5mm high spot on flywheel even after it was allegedly skimmed. Who is responsible for my new clutch plate being bent?
Experienced mechanics share their insights in answering this question :
This cannot be blamed on either party since the flywheel would show a spot that is low or high after it was machined. The flywheel may have what is called a "hot spot" from the last clutch slip which caused the flywheel to get hot, creating a hardened spot that would be hard to machine. At this point, replacing the flywheel and clutch with new parts will definitely solve the issue.

If you’d like a second opinion on this problem, consider enlisting a certified mechanic who can diagnose the shuddering you’re experiencing and perform the necessary checks on these components to find what exactly is at fault.

These components connect the engine to the transmission in manual vehicles, using the clutch to transfer power to the wheels. Moreover, if the flywheel is damaged, it will be much more difficult to successfully change gears and could cause irreversible damage to the clutch.
Most importantly for drivers, the flywheel connects the engine with the transmission via a clutch to transfer power to the wheels.
The flywheel should be considered a wear item just like the clutch, and should be replaced when a new clutch is installed. Surface wear is another reason for replacement. The friction surface of a dual mass flywheel will wear the same as an ordinary flywheel as a result of normal clutch operation.
Stop-and-go traffic, towing heavy loads, abruptly engaging or “dumping” the clutch, and riding the clutch (keeping your foot on and halfway engaging) when decelerating are all factors that can lead to signs of clutch failure. Sprag clutch failure symptoms are easy to spot if you pay attention to your vehicle.
Gears Slipping

If you notice the gears constantly slipping when you shift the clutch, a bad flywheel could be the culprit. There are other reasons for gear slippage, but if you also notice small metal shavings in the transmission fluid, the flywheel is to blame.

As a rule of thumb, most clutches will last in the region of 60,000 miles before the need for replacing. However, we have had to replace some at around 30,000 (or less), and we`ve seen some clutches that have continued to keep going past 100,000 miles.
There`s no definite life of Clutch Plate. Some People have observed Worn out Clutch Plate in even 10000 Kms and some are having no issues even after driving more than 1 Lakh Kms without any need to replace Clutch.
Flywheels – When They Should Be Changed

The most important thing to check is the flatness of the flywheel because any small degree of warpage (or “runout”) will cause problems. Using a dial indicator or a straight edge across the flywheel at different points will give an indication if there`s any wobble.

Bad driving habits: Riding the clutch, pulling loads that are too heavy for your vehicle, driving in the wrong gear and placing your vehicle in reverse or first gear with the engine off are all poor motoring habits that can cause damage to the flywheel.
“Riding” the clutch is the most common reason for premature clutch failure. Even the slightest pressure on the pedal will partially disengage the clutch, causing the release bearing, pressure plate and flywheel to overheat.
That`s because when a flywheel is damaged, it no longer has an even surface, which can cause the clutch to slip, vibrate, or judder. This vibration makes operating the vehicle unpleasant or even impossible, depending on the damage or wear. It also makes it easier for the clutch to overheat.

If your flywheel is making an unusual noise, this indicates it has become severely worn and should be replaced as soon as possible. Flywheels usually last around 80,000 to 100,000 miles, if not more, but as soon as you notice symptoms of an underlying problem, you should have your car checked by a mechanic.
The average lifespan of a clutch is anywhere between 20,000 to 150,000 miles. Luckily, your clutch will likely give you ample notice that something is going wrong.

I can’t go into 4th or 5th gear and clutch does not engage after a recent clutch job, clutch release while in gear does nothing.
ANSWER : I would rule out the axle not being pushed all the way in. That would effect all speeds and gears. That you can engage gears other than 4th and 5th leads me to 2 m possibilities:
1. Shift linkage mis-adjusted.
2. Possible bent shifter fork internally.

If it feels like you can engage 4th and 5th with the engine OFF, then I would lean towards a clutch release issue.

I have a Mitsubishi Lancer LS 2002 it has a new clutch pressure plate and throwout bearing I bled the clutch 5 times I driver for
ANSWER : It could be that you have a leak in the clutch master or slave cylinder. Either one can cause the clutch to lose pressure that way. Unfortunately, The 02 Lancers had a "concentric" slave cylinder that requires transmission removal for replacement. So it’s really good policy to change the slave cylinder any time you replace the clutch. In later years, the engineers came to their senses and changed it to a conventional slave cylinder that mounts on the bell housing and is easy to replace. If you have been bleeding the clutch system you’ll know which type of slave cylinder you have. Either way, you can have this taken care of at your convenience by contacting Your Mechanic. They can send a technician to your home or office to check out your Mitsubishi and let you know what it will take to get your clutch working properly.

Clutch lost all hydraulic pressure after difficulty engaging gears while using the clutch.
ANSWER : Hello. This situation is usually a failure of either the clutch master or slave cylinder – they simply wear out. If you have any clutch fluid on the drivers side front carpet, the failure is the clutch master cylinder. If the fluid loss is on the ground, under the rear of the engine, the slave cylinder is the failing component. It is often more economical in the long run to replace both with your advanced mileage as they wear at similar rates. I would recommend having the clutch master and slave cylinder replaced by a mobile, professional mechanic, such as one from YourMechanic, to repair this problem.

Issues with clutch cable on a newly installed clutch/flywheel.
ANSWER : Hi there. If the cable was loose before you changed the clutch out and is loose after the clutch was changed out, then the cable is stretched. I recommend replacing the clutch cable and adjusting it to the correct pedal height. If you need further assistance with your clutch cable replacement, then seek out a professional, such as one from Your Mechanic, to help you.

Clutch pedal stays to floor. Replaced master cylinder. Clutch push rod broke. Also do I need to change slave cylinder
ANSWER : If you have an issue with your clutch pedal going to the floor, the slave cylinder is normally the cause of this circumstance.

Also, if the push rod has been broken the first step would be to track down a new one because that push rod is a very necessary part of the clutch pedal system.

Once a new push rod has been located and installed, I would recommend having a new slave cylinder installed as well.

If you are in doubt about this repair, I would recommend having it performed by a qualified professional, such as one from YourMechanic. One of our mobile technicians will be able to come to your home to diagnose the issue with your clutch pedal and replace your clutch slave cylinder as necessary.

Clutch has noise when pressing clutch pedal – 2015 Subaru WRX
ANSWER : Hey there, a noise when pressing the clutch is generally tied to the throw out bearing or release bearing. It may be necessary to replace the throwout bearing and have the clutch assembly inspected while the transmission is out of the vehicle. If you want to have this taken care of, a certified professional from YourMechanic can inspect the noise and have this issue corrected.
