hello,

I pulled the m46 out of my 740, but the flywheel/clutch/pressure plate is just sitting there. How do I get it off?

thanks,

-tal

Remove the 6 clutch cover bolts. If needed, pry gently around the cover, evenly.
Remove the flywheel bolts. You might need an impact. Be careful, it might fall, and it is heavy.

If you intend to re-use the clutch, it is recommended that you turn each bolt no more than 1/2 turn at a time during removal and install.

make sure to matchmark the flywheel relative to the crankshaft prior to removal (there is a crank position sensor on the back of the flywheel)

Oh yeah, forgot that. And it cant ake 2 turns per bolt at a time. 1/2 would take half the day. IMO
I did catch 2 students pulling on a cover with one bolt still attached once. Heinous.

I didn't mark mine, but i am lso using a diff dis and had the flywheel resurfaced.

Some clutch pressure plates had crap allen bolts or 6 point hex bolts.

The flywheel, you can hold it and loosen the bolts with a ratchet.

I just did this on thanksgiving, haven't touched it since.......nor do i want to anymore with so much stuff going on...

Do the rear main as well if you don't know how long ago it was, and go for a new pilot and throw out bearing....don't forget the clutch alignment tool!!!

Easy stuff. My method was put a 24mm socket on the crank pulley nut and undo the clutch.

To get the clutch off you need to undo the allen head bolts on the clutch.
Make a mark where the clutch is relative to wheel before removal (if reusing clutch) Use a good allen tool to get those bolts off. They can be a bitch.

Once the clutch is off you have the flywheel bolts. Counterhold the crank at the pulley, as mentioned above, and undo wheel. Dont worry about the orientaition of the wheel. You just put the wheel back on so that the sensor portion (break in hole pattern) is visible thru the starter hole at TDC. :wink: Lh2.2 people need not apply. Only 90+ folks.

It is foolproof because you would have to put the flywheel on misoriented by an entire bolt.

Get the pilot bearing out by filling the cavity with grease and putting a socket in the hole to push the bearing out. Socket must be approx size of hole. Believe me, it works.

On my 244, my clutch was held on with dumbass allen bolts. My friend and I got vice grips to put on the allen wrench and both of us pushed upward while the bolt was at the bottom of the flywheel. Then for the flywheel I took a piece of angle Iron and drilled 2 hols in it which was the length between 2 of the studs that help hold the clutch on the flywheel. I rested the angle Iron on the floor to prevent the flywheel from moving. This worked wonders. After all this by hand I finally broke down and purchased an expensive air compressor along with air tools. Now I think I can change a clutch in under 6 hours instead of 2 days.
