Re-surface flywheel required?

[jake7140]

While I'm replacing the blown tranny I'm doing the clutch too. Do I NEED to resurface the flywheel or only if it looks torn up. It has had a stock clutch in it up to now.

Not replacing pilot bearing, just clean/lube, new throwout. Anything else I'm missing?

Can it be done without moving/removing engine?

It is not absolutely necessary.

A pilot bearing, however is a good candidate for replacement when you have the tranny out.

One thing you have to watch for on the flywheel is excessive "bluing" or overheating. In that circumstance, replacement is better than resurfacing.

Steve, replacing the pilot bearing & grease seal is a good idea per joeg info. You do not need to remove the motor but you will need to have a jack on the rear of the motor to suport the rear of the motor & so that you can allow the motor/trans assembled to rotate on the front motor mount so that when you remove the trans screws to remove the trans the top of the trans by the shift housing will clear the tunnel.

use the metal pad 4 puck disc and it will resurface it for you.

And as Tak mentioned in another thread, beware the tricky pilot bearing. If its dry and sketchy looking then go for it. But if it looks sweet, leave it be!

Getting the right puller can make a difference, although I have had huge battles where even the puller didn't do the trick. Plan a few extra hours just in case if it looks bad.

Isn't it possible to remove the pilot bearing with "hydraulics"? In other cars (never done a Mazda), you simply fill the cavity with grease (pack in where necessary). Insert the disc alignment tool end into the bearing, and strike the other end with a hammer. The bearing should pop out from the hydraulic pressure behind it.

Ive used this method many times with roller and bronze bearings alike.

Good racing.

David,
Do you mean rotate the back of the engine down to slide the tranny down & out?
