Clutch Flywheel How it is Resurfaced Reconditioned

When replacing a clutch should you have the existing flywheel resurfaced or purchase new? It's important for the new clutch disc to sit flat and make good contact with the flywheel and pressure plate for proper operation. Original flywheels parts can be resurfaced or aftermarket parts are available at a reasonable price. Sometimes using aftermarket parts can sacrifice quality. In this video I discuss what I chose and why. It's important to get it right because nobody wants to have to pull out the transmission for a new part that fails. Thanks for watching. -Glen (Ozz)

I have used a bent valve for many years for holding flywheels when torquing up or removing flywheels.seems to be the best and easiest tool to use.

[@jay92889]

Cool video man! Never seen this process but been curious. I had an accord I got cheap to drive while I manual swapped my own accord and whenever I was in stop and go and the flywheel or clutch would heat up the engagement started getting jagged and chattery. I figured the heat lifted the imperfections and bumps higher and made it chatter versus when it is cold and smoother. Never skip a resurfacing!

[@ozzstars_cars]

Got that right! Thanks Jay

[@stuzman52]

I agree that it was better to use the OEM flywheel as that aftermarket had way too many holes to balance it. Nice footage of the machine shop operation.

Luk used to be the best aftermarket clutch you could buy. Luk used to make the clutches for the dual clutch Powershit transmission in the 2013 and newer Ford Focus and Fiesta. I heard that Ford has or is in the process of suing them. Your "swiss cheeze" flywheel is an example of Luk quality now.

[@ozzstars_cars]

That's a shame, like so many other parts, quality going down the tubes.

[@brianspangler3771]

Had a new clutch put in my 98 cobra mustang. I bought a new billet steel flywheel for it but it ended up having a defect and had to use the stock flywheel which wasn't resurfaced like it was supposed to be which led me to being interested in the process and found this video. Very interesting.

[@ozzstars_cars]

Yes it's important the flywheel surface is completely flat and smooth or clutch chatter can be an issue.

[@brianspangler3771]

My machine shop charges $50 to do a flywheel. He does them while a wait. That must be why your machine shop has a sticker on his machine that says Cash Cow.

[@ozzstars_cars]

I bet that machine has to resurface a lot of flywheels to pay for itself. Nice one to have.

You can buy at Amazon for $47 plus shipping.

If I send mine it will cost the shipping plus the $50. I am from Florida.

[@rockerpat1085]

You didn't say what this flywheel came off of. Does it have an external slave cylinder or internal? If external it's ok to resurface the flywheel you can adjust for the material taken off, but if it's internal you can run into problems with the clutch pedal height!!! The pressure plate fingers to throw out bearing distance is finite and is not adjustable. You need to measure the thickness of the flywheel before you turn it and after it is resurfaced and add a shim behind the flywheel and crankshaft equal to the amount removed!!! If you don't do this the clutch pedal height will be lower and can cause shift problems!!! Yes I've been burned by this and no longer turn flywheels in my shop!!! I only replace them with new full thickness flywheels!!! Just a helpful tech tip from a career mechanic and shop owner!!! Keep Rocking it out!!!

[@ozzstars_cars]

I'm pretty sure you did not watch the entire video. 1) what vehicle? 0:10 mark, regarding flywheel thickness 6:30 mark. Have a great day.

[@rockerpat1085]

@@ozzstars_cars I missed you saying it's from an 87 Ranger. So internal slave cylinder!!! That means you need to adjust for the material taken off of the flywheel. That was not discussed only how much can be removed. So if you don't know how much you remove, you can't know how much to shim. Let's say you ground 100 thousand off the clutch surface of the flywheel, you now need to install a shim behind the flywheel 100 thousand thick. This way your throw out bearing is touching the pressure plate in the correct location. When you remove material from the flywheel, the clutch and pressure plate has now moved towards the engine by the amount you cut off. Because of this the clutch pedal height inside the truck will change and can cause shifting problems. I.E. hard to get into gear, grinding of gears. That's why it's important to shim the flywheel when turned on internal slave cylinder clutches!!! Have a good one and Keep Rocking!!!

[@ozzstars_cars]

@@rockerpat1085 i understand your.point if it is an extreme amount of material removed. Taking .005 off the flywheel has no effect in this case. That's half a human hair. Btw, the clutch works.great and the trans shifts smooth as silk I this case.

[@thebossman80s]

That flywheel you grinder down looked like it had a step in it, the inside was deeper than the outside of the rim. I think it was supposed to look like that and the guy grinder it down totally flat across the whole surface! I’m not sure it was supposed to be done that way, I thought he was supposed to skim the centre then skim the outer half at a different height

[@ozzstars_cars]

Charley, flywheels should not have two levels. That is where the original clutch disc wore down the steel. All good and now chatter with a new clutch kit.

[@thebossman80s]

Ozzstar's Cars ok thanks, I’m getting my transit van done next week and I’m not sure wether to have the solid flywheel resurfaced or replaced. After watching all these videos I think I’ll have it resurfaced even though it’s done 100,000 miles

@@thebossman80s good call. A lot of the aftermarket parts are junk. LuK is Ford "oem" but the one I received looked like swiss cheese so I stuck with the 30 year old original. 😉

Wow thats a lot of holes! I've never seen one with that many holes. Normally Luk are very good too?! Someone done a sneaky box swap in the parts store? haha We did have a few years ago a big parts place got ripped off with a container of fake Luk Clutches- their name rhymes with Duro. It's nice when you get a good machine shop that do good work.

I know the pressure plate and disc had LuK stamped in it. Yes LuK is oem for Ford clutch parts. The flywheel just has a number molded in it. I wonder if what I got is the real deal?? hmmm
