After going through all the trouble that is involved with removing the transmission and clutch,I find that the flywheel is not removable unless the oil pan is removed. So how do you guys recondition the flywheel clutch surface without removing the flywheel? Im sure not everyone pulls out the engine everytime they do a clutch change.Also,how does the pilot bearing come out? Is it machine pressed in or can it be removed with a slaphammer? And what keeps the pilot bearing lubricated? Is there a bronse bushing behind the pilot bearing pressed into the crankshaft?

The pilot bearing can be pulled with a pilot bearing puller[hook type tool]. You can buy permanately sealed bearings, and I just put some grease in the hole before hooking up the trans. not too much though as it could end up on the clutch. I have never attempted to re-surface a flywheel with it still in the car.

Gary, to reface the flywheel, it needs to be removed from the car. Yes, most of us pull the engine, if we are going to replace the clutch. I would not try to remove the pan while the engine is in the car and the transmission is not, due to safety concerns. To remove the pan, you have to remove the front motor mounts and jack up the engine. Without the rear motor mounts, there is nothing to keep the engine from moving out of place. If your flywheel does not have deep scores or heat checking, you can clean the face with an abrasive pad. Tom

As TomO says, if the surface of the flywheel isn't scored or burned you can resurface it by using a Scotchbrite wheel in a drill to clean it up. We do that on every clutch job, anyway, to break the glaze. To remove a pilot bearing without a puller, fill the bearing and its cavity with grease, then insert either a pilot tool or a close fitting punch and give it some whacks with a hammer. It will force the bearing or bushing out. The pilot bearing should be replaced when the clutch is replaced.

Is a scotchbright abrasive enough or should a mild grinding stone in a drill be used? Thanks...

I would not use a stone chucked into a drill because it is too hard to control. I vote for the Scotch Bright pad. If clutch chatter was a problem, I'd bite the bullet, take it out, and have it re-surfaced at a shop.

The Scotchbrite wheel will do a good job, unless you get it full of grease or dirt. Wipe down the flywheel clutch surface with a good solvent before you begin. Take your time and the surface will eventually be ready for the new disk. If you are installing a sealed pilot bearing, don't pack it with grease. The bearing can be forced out of place by the input shaft pilot. A sealed bearing needs no grease, which will only end up on the new clutch disk.

What color scotchbright wheel should I use and also how do I know if im getting a sealed bearing when I order.There is a choice of either a roler bearing or a bronze bushing in the catolgue,but it does not say if it is a sealed bearing. The price is under $5.00 . These are from Macs. Thanks....

Gary Macs has it listed in their catalog A7600 and the description says "sealed ball bearing" Ted
