Should i replace flywheel with clutch

Check the flywheel for play if its dual mass. It should rotate like 3 - 5 degrees, any more than that and it may need replacing. I just replaced my clutch and DMFW at k. My mechanic said he would keep the original if it was still in good shape but it was too far gone. Glazed and heat marks. Since its got rubber in there I would replace it if your car has high mileage even if it looks ok. Plus as someone else said you are making things worse every time your clutch slips in high gear Originally Posted by boo Originally Posted by 5mall5nail5.

Play: Not all DMFs have rubber inside. Most use internal springs that allow flex in the two halves. The internal springs in the DMF wear out over time. The flywheel is also a form of harmonic balancer.

I just wish these components didn't cost so damn much I've seen many reuse dual mass with a resurface. But usually only replaced when abused or worn out of spec. Worn pilot bearings will cause misalignment of the shafts, leading to fast wear of clutch and throwout bearings as well as problems during engagement and disengagement. As clutch parts engage, they allow smooth coupling of the drivetrain as the clutch disc and flywheel come together to transfer driving force to the wheels.

The disc is located between the engine flywheel and the clutch pressure plate and is clamped tightly between these two members when the clutch is engaged. Clutch discs may also be described as friction discs. The clutch pressure plate is a spring-loaded metal plate that spins with the flywheel and applies pressure to clamp the clutch disc firmly between itself and the flywheel. When the clutch is engaged, springs in the pressure plate force the clutch disc against the flywheel.

When the driver depresses the clutch, this bearing pulls the pressure plate and clutch disc away from the flywheel to disconnect the engine from the drivetrain; when the driver releases the clutch pedal, it allows the springs to push everything back together and the clutch is engaged. The throwout bearing does wear and, in extreme cases, will squeal when the clutch pedal is depressed. By nature of what clutch discs are designed to do, their friction material is under a constant state of wear during the normal process of depressing and releasing the clutch.

Naturally, a clutch disc needs to be replaced as a wear item. If the secondary flywheel rotates with hand pressure, the ring is slipping and the flywheel needs to be replaced. If you simply bolt in a new clutch, chances are your customer will have flywheel problems at some point down the road because of the weakened springs in the flywheel. The flywheel should be considered a wear item just like the clutch, and should be replaced when a new clutch is installed.

Advertisement 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.

The clutch surface may become rough, grooved or develop cracks or hard spots. Minor scoring and grooving is acceptable, but if the surface has hard spots, is warped or cracked, the flywheel must be replaced.

Resurfacing a dual mass flywheel with a rough or grooved surface is usually out of the question because of the two-piece design of the flywheel. To resurface a dual mass flywheel, the unit would have to be taken apart so the secondary flywheel could be remachined.

Most of these units are not designed to be disassembled or serviced by technicians, so replacement is recommended if the unit shows a lot of wear or is making noise.

Add in a couple hundred bucks for a new clutch and clutch disk, plus labor to replace all the parts and you end up with a sizable repair bill.

A more affordable alternative is to replace the OEM dual mass flywheel with an aftermarket one-piece solid flywheel which also requires a different clutch and clutch disk.

In most cases, you can get a new flywheel and clutch for hundreds less than what it would cost to replace a dual mass flywheel itself. Advertisement When the one-piece solid flywheel replacement kits were first introduced for the early Ford and GM dual mass flywheel applications, some people said the kits would cause more problems than they solved.

They said a solid flywheel would not provide enough dampening to protect the gears in the transmission from shock loading and would cause the transmission to fail. It never happened. By using a slightly larger clutch 13 inch as opposed to a 11 or 12 inch clutch in the stock dual mass flywheel with redesigned hub springs in the clutch disk, the solid flywheel replacement kits proved to work just fine in these applications and caused no harm to the transmission.

Learn which signs are indicators that you should be replacing your flywheel. Riding the clutch while driving can often cause this to happen. Vibrations in the clutch are usually a sign that the spring mount mechanism on the flywheel has failed.
