Pilot bearing Do you have to remove the flywheel in order to remove the old bearing.

The transmission has to be removed. If it's a frobnt wheel drive car, the front axles have to be removed in order to remove the transmission.

The flywheel should be removed, too, and machined flat by an automotive machine shop. With the flywheel removed you may wish to replace the engine's rear main seal since it may leak oil.

The clutch often comes in a "key", which includes a new clutch pressure plate, clutch disk, and a "throw-out bearing" (used by the clutch fork to disengage the clutch). The kit may alos include a broze "pilot bearing", which is used to center the transmission's input shaft inot the engine crack shaft. The kit will include a placstic alignment tool to help the clutch disk while the new pressure plate is attached to the flywheel.

You definitely have a pilot bearing, ask a. Napa dealer to find you one, if they don't see it in the book listed.
its going to be part of the clutch kit you'll be buying to replace your old one.
in the kits you get a pressure plate, release bearing, disc, alignment tool, and pilot bearing, Beck Arnley is a good choice.
if you want just a bearing you'll probably need, the input shaft diameter where the bearing rides, the inner diameter of the flywheel hole it's inserted in, and the depth of the hole in the flywheel.
you should have to much trouble finding one.

You first have to remove the transmission, then remove the pressure plate and clutch disc from the flywheel. the pilot bearing in in the center of the flywheel it can be removed by packing the hole with grease then take a piece of round stock that is slightly smaller than the hole and giving it a quick sharp blow with a hammer this should force the pilot bearing out then wipe out the grease and install the new pilot bearing

Disconnect the battery, disconnect the Hydraulic Line from the Slave Cylinder, Remove the Starter (2 bolts, 2 wires. Bolts are 14mm, 1 wire is 12mm, 1 plugs in), Remove the Driveshaft(s) (4 12mm bolts) Remove the 6 bolts from the bellhousing (4 are 14mm, 2 are 10mm)
Remove the bolt from the Transfer Case Mount, 12mm (only if it's a 4WD, if it's 2WD this doesn't apply), remove the 2 bolts that hold the Transmission Mount to the Crossmember (12mm or 14mm, it varies)
Slide the transmission back on the crossmember, away from the engine, I recommend running a ratchet strap across the frame to balance the transmission.
Remove the Pressure Plate from the Flywheel (Six 10mm bolts), Inspect the Pilot Bearing (if it needs replaced, you'll need to remove the Flywheel which is held on with six 18mm bolts, drive out the old bearing and drive in the new one, reinstall the flywheel, using Threadlocker on the bolts, torque the bolts to 100 ft lbs) Install the new clutch disc and Pressure Plate, with the centering tool inserted through the disc into the pilot bearing. Use thread locker on the pressure plate bolts and torque them to 20 ft lbs. Remove the centering/alignment tool after you've bolted it together
Remove old Throw Out bearing from input shaft on the transmission and slide the new one on. Slide the Transmission forward (make sure the input shaft slides into the pilot bearing, don't force the transmission into place or you could damage the clutch disc or break the input shaft) Torque the Bellhousing Bolts to 40 ft lbs (4 14mm bolts), Torque the 2 10mm bolts to 14 ft lbs, Install the Starter (torque bolts to 23 ft lbs), Reconnect Hydraulic Line to Slave Cylinder. Torque Transmission Mount Bolts to 30 ft lbs.
Reinstall Driveshafts, torque bolts on flange/yoke to 40 ft lbs. Fill Clutch Master Cylinder with DOT-3 Brake & Clutch Fluid, Open Bleeder Screw on Slave Cylinder and bleed the air out of the system, close bleeder screw.
Reconnect the wires to the Starter, Reconnect the battery.

The pilot bearing is pressed into the flywheel and you need a pilot bearing/bushing puller. Some A/P stores will rent it to you for free (deposit). the throwout bearing is held onto the clutch fork normally by clips. Sometimes you have to take the "fork" out to get the bearing off.

Make sure to note how "deep' the pilot bearing/bushing is so that when you install the new one it is set at the right depth.

The first thing to do is to have the flywheel re-surfaced because a warped flywheel will cause the clutch to chatter or shudder when you let up the clutch pedal, and also be certain that the pilot bearing is replaced, it can be difficult to remove the pilot bearing from the end of the crankshaft and you will most likely need to obtain a good pilot bearing puller to remove it.

Clean the bell-housing and the rear of the engine block while the flywheel is being re-surfaced, and be sure that all of the old clutch material and dust has been cleaned from the bell-housing and the rear of the engine block, and contamination from an old clutch disk will lead to early clutch failure.

After the flywheel has been installed and torqued down, then you will need to mount the clutch disk and the pressure-plate assembly together onto the flywheel, and be sure that the clutch disk is facing the right way (usually the spring hub will go towards the pressure-plate assembly), and then start to install the pressure-plate assembly bolts but only hand tighten them for now. After the bolts have been started then use the clutch disk alignment tool that should have come with the clutch kit to align the clutch disk with the pilot bearing, and when you have it aligned so that the alignment tool easily slips through the clutch disk and into the pilot bearing, then tighten down the bolts to the pressure-plate assembly one turn at a time in a criss-cross pattern until the pressure-plate assembly is flush with the flywheel and then you can torque down the pressure-plate assembly bolts. This is a critical step and the better aligned that you get the disk and pilot bearing, and the easier it is to remove and replace the alignment tool, the easier it will be to install the transmission, and the transmission input shaft should slip smoothly through the clutch disk and into the pilot bearing and not have any difficulties mounting up to the engine, and if the transmission hangs up when you are installing it and and the transmission input shaft does not go straight in through the clutch disk and into the pilot bearing, it can damage the clutch hub and the clutch will chatter or shudder when you let the clutch pedal up, and it will shorten the life of the clutch.

After the clutch has been aligned then install the throw-out/release bearing onto the transmission input shaft collar and the throw-out/release bearing fork, and use a lithium based grease on the pivot points of the throw-out/release bearing fork and where the fork contacts the throw-out/release bearing, and if it did not come greased, then lightly grease the inside of the throw-out/release bearing with a lithium based grease and do not over do it on the grease, you want just enough grease to keep the throw-out bearing and the input shaft collar lubricated but still have a smooth operation to it, and you do not want to damage the clutch from oil or grease contamination as this will cause the new clutch disk to slip.

The transmission can now be installed into the vehicle and be careful not to hang the transmission input shaft on the clutch disk or the clutch disk will be damaged. I hope that this information will help you to replace that clutch with a proper quality repair that you will get the most out of.
