How long do flywheels last

Since I have put on another 50, I recently had the LN Engineering IMS retrofit installed and during the process, the flywheel was removed and measured.

It was out of spec. The truth is that since I received the car, I always found the car a bit difficult to launch compared to the other manual cars I have owned over the past 20 years. I have never ever abused a clutch, and had to replace it Since the flywheel replacement, the car is much easier to launch, and overall is easier to drive. My conclusion is that the flywheel was bad from the get go and that either it was defective from the start or one of the previous 2 owners previous owner is a friend damaged it.

I think that launching a car puts a lot of stress on a flywheel - particularly a dual-mass one. I would suspect that it would wear out quicker under those conditions It just barely didn't pass the spring back test so I replaced it. As was said earlier the way you drive will have a big impact on the life of the clutch and flywheel. I could have let mine go longer but I was already there and it was a good time to change it out.

Steve 2. I had to replace mine at 35k but I was not the original owner so I can only speculate as to how it was driven, my motor mount went shortly after that. A friend of mine has 98k and it was just bearly out of spec. This can be a high profit part for shops. Originally Posted by Wayne at Pelican Parts. Thread Tools. All times are GMT The time now is AM.

Manufactured from to A fully functioning DMF will offer smooth acceleration with very little or no vibrations at all, depending on your engine. Before we get into specific ways these units fail, we have to clear one thing up — DMFs wear out over time. The key to a long lifecycle of this part of your clutch system is to know what not to do during your everyday commute. Here are a few things that cause DMF failure:.

Since replacing a DMF is no cheap affair, many are considering simply converting their dual mass flywheels into single mass flywheels. The idea here is to simplify the entire assembly and make the clutch system more robust and durable. But does this always work? The issue most of these conversion kits bring to the table is the lack of vibration dampening — the very thing DMFs were invented to counter. If the whole problem came down to ride comfort, there are undoubtedly many people out there who would rather have a more reliable car in exchange for a shaky idle.

Letting all of those vibrations reach the transmission can cause serious problems. Some models will easily accept a single mass flywheel conversion kit and work just fine, but for some, that would be the last straw. If you decide to go ahead with the conversion, make sure that you have all the facts. At the end of the day, DMFs have proven to be a necessary evil that keeps things running smoothly. Taking good care of your car will be more than enough to prolong the lifespan of your flywheel and postpone that expensive swap job.

Ignoring this issue can only create cause more problems down the road. You must be logged in to post a comment. This site uses Akismet to reduce spam.
