When I removed mine my motor was on a stand and I locked the flywheel and also put a jackstand under the crank pulley. This kept the crank from turning and the motor from moving down when I put force on the nut. Also plan on having a pulley puller to remove pulley from crankshaft.
my standard 1/2" 90psi craftsman impact gun couldn't even touch the crank bolt after I had the engine out. You'll need something more substantial in terms of a gun to break it loose usually.
Since I was pulling the tranny and flywheel off anyway to replace the crank seal I just drilled two holes in a piece of steel plate, bolted it back to the crank where the flywheel mounts and used it as a lever when cranking the pulley bolt out with a 3/4" breaker bar and extension.
jagibbs: How many ft lbs of torque does that gun put out? I see a 90psi gun on craftsman's website that puts out 350ft lbs which should be more than enough.
^Trickster^, 93TurboDeuce: How much torque do the impact guns that you use put out?
I'm not sure but it's probably the one. I suspect that it does not put out as much torque in reverse than the max setting in drive (just from using it a whole lot I gathered this). It can barely loosen my strut pinch bolts torqued to 188 ft-lb.
EDIT: it looks like I have the 500 ft-lb gun. Sears item #00918852000 Mfr. model #18852. If I was going to buy another one, I'd spluge a little more and get something a little more heavy duty.
I just noticed that the maximum torque rating is always lower than the working torque rating, therefore my 500 is probably only good for about 250. Combine this with the fact that removing bolts that were once torqued to 250 for example, may require extra to break them free years later.
2nding using a big screwdriver to lock the flywheel. The craftsman screwdrivers are fantastic for this. Just get a good socket, socket wrench, and cheater bar and it'll come off without too much problem.
Ok... I had to work with wood unfortunately. I had doubts about it holding together but I ended up snapping the drill bits first. I then used some tight fit screws. Same story. I think I'm going to have to spend some money on a puller or rent an impact gun.

The first time i removed my gen 2 one was the most difficult, i hate to take the engine to my mates garage and use his impact drill and compressor as mine wouldnt undo it for the world, his big one is around 1000ft/lb and we had it on and off waiting for the compressor to charge for about 10 minutes!
ah, pat... you have no idea how many innocent drill bits i killed trying to use that.. lol. I ended up renting an electic impact gun that was one size up from 1/2" drive... it worked on the first try = )
Broke the inpact socket, snapped the 19 mm 1/2" drive, snapped the 19mm deep socket and now the corners are rounded. Oh, tried the starter and that didn't work either.
Now what to try?
if you rounded a 19 mm bolt thats pretty impressive. But anyway are you sure the bolt isnt an 18mm? thier is no way a 19mm is going to round out unless you used the wrong size, if this is the case snap-on and im sure others make these sockets with reveresed threads inside. Buy the right size or the next size up and hammer it on thier. Then use the impact again. Just make sure you buy a 1/2 inch socket if your using a 1/2 inch impact.
I'm guessing the impact socket wasn't make in the USA??? NEVER use anything not made in the USA for tools or it will break sooner or later, usually sooner.
I remember that my crank pulley bolt was starting to round a bit over the years...who know what the PO's did with it. I opted to put a brand new crank pulley bolt back in though. It is 19mm.
Update: Mac AW234A 1/2" Impact Gun didn't work for me. I'm not sure of the capacity of this gun since it was only rented... Just an FYI for other people who might read this thread in the future.
Is there anyway that I can still use the starter if the engine is out? What would I have to reconnect in order to use that method??
