Sharp cold chisel
Ratchet and socket
Bench Vice Or a brave helper
Block of wood
Optional - cold beverage of choice
One flywheel with bad ring gear
One flywheel with good ring gear
4 Machine screws and lock nuts (sorry I didn't note the size I carried the ring gear and a rivet to the parts store I think 1/4 - 20 but I may be wrong)
The ring gear is held on by 4 rivets - the bumps between the cooling fins in the pic. These are fairly soft.
Place a flywheel(I recommend starting with the bad one in case you learn something you should not do to the good one) in your bench vice putting a piece of wood on the ring gear side to keep from breaking it.
(Tech tip - make sure there is as much crap as possible on your work bench. It so much nicer to work with stuff falling on your feet every time you use the hammer.)
Trust me you want to use a vice or this will happen - ouch!
Using the cold chisel and the hammer (duuh) cut the heads off the rivets. Take care to not break a cooling fin off. Don't try to break the heads off in one swing. Work your way through. It took me all of 10 seconds per rivet.
Place the flywheel, ring gear side down, on your block of wood. You don't want to break that ring gear you are harvesting. Then use the punch to drive the rivets out.
You may need to use a screwdriver to pry the ring gear off. One I mine I did the other just fell off.
Repeat for the second flywheel.
Clean the debris off the good flywheel and the good ring gear.
Then place the ring gear on the flywheel. There is only one way it will go the bolts are not symetrical so check before you start bolting things down.
Make sure you use lock nuts so things don't vibrate loose.
The bolts I bought were about an inch too long so I had to cut them down. It didn't take long.
START ALL BOLTS BEFORE TIGHTENING ANY! This is especially true when you are using lock nuts. You don't want to have to go out and buy new ones if you mess up.
Finally tighten all the bolts down and you are done.
Somehow the finished pic came out like this
So you have to use your imagination, because I am not taking it back off the engine just to make you happy. Yeah, you. You know who I am talking to.
If you did this right you spent about 30 minutes. IF you did it like I did - 2 hours. I had to make 2 trips to the hardware store (I broke a bolt), and search high and low for every tool I needed, then there was the inevitable finding where Heath and Gunner had run off to every 5 minutes.
