I'm in angst over the M20 x 1.5 bolt that is supposed to pop off my rotor. What pitch should I be getting and where can I find this bolt without buying it in bulk?

The answer is....



M20x 1.5 or a Large Subaru drain pain bolt which is the same size but needs a washer glued to the end to get a hair more length.







Subaru oil pan plug $2.99

Subaru oil pan plug with washer glued on to make it long enough

You'll need something to hold the flywheel from turning. Some people use a strap wrench. That's great but I didn't have one big enough so I used a drill bit stuck backwards into one of the holes on the flywheel periphery. The block of wood is resting against the starter gear. I didn't want the drill bit directly on the starter gear shaft. Tightening the oil pan nut to pop off the flywheel barely stressed this hillbilly rigged set-up.

Great post - put it in with the keepers.

And if you local FLAPS doesn't have the screwbaru bolt (no on in my area had one), you could get the real deal on FleaBay for $11.50:



Flywheel Puller



I used an auxiliary oil filter bolt from an Acura that a friend had lying around his shop, that was just blind luck on my part.

See my response in the redundant thread.



Let's take the rest of the discussion over there, so it's all in one place.

I wouldn't do what is in the second photo. Two things can happen ...

1. You can bend the shaft of the starter gear.

2. You can break the engine case where the shaft goes into the engine.



Use a strap wrench and don't end up hitting yourself over the head because of damage! Good engine blocks are hard to find.

Or another red neck rig, if you don't have a strap wrench big enough:

I didn't even hold mine with anything but my hand. I put in the flywheel puller bolt and hit it with my air impact gun. The flywheel dropped off in my hand in about two seconds. It didn't seem to do any damage to anything.

That's the way every pro mechanic I've ever seen does it...
