Re: Crank gear removal
Hot wrench is quickest if you aren’t going to try and reuse. Don’t cut all the way to the crank, though. Common sense

Re: Crank gear removal
Good grief !! Don’t, please don’t, use an oxy acetylene torch to CUT the crank gear off. I’m picturing slag and deformation of the crank. Use a 30 ton press and maybe oxy acetylene to WARM UP the crank gear. Press it off. If still unsure or unconfident, take it to an auto machine shop. They have the equipment necessary
I don’t know why I turned out this way. My parents were decent people.

Re: Crank gear removal
Did that make you faint, George? Mike is very experienced . It’s off in 30 seconds, and of course, I find common sense isn’t so common. So, I’ll add this. Don’t cut half way into the crank journal. Cover the exposed crank with something. You PROBABLY should take the crank out of the car AND the engine. Do not spray molten metal into your car interior that the doors are open on. OR, on your children watching closely. Don’t use the cutting torch next to a national forest that has high fire alert drought conditions. Put oil dry on gas puddles in your shop. Cover your gas can, and don’t leave it tipped on its side. DON’T CATCH YOUR HAIR ON FIRE, BUT IF YOU DO , HAVE AN EXTRA BEER HANDY! You can and should spray molten metal on the neighbors cat. I’m probably forgetting something. Duh

Re: Crank gear removal
Iam enjoying the entertainment. The motor is on a stand; with the pan off. The flame wrench- while appealing- maybe not so much. A cut off wheel? A person couldn't get in too much trouble. Could he?

Re: Crank gear removal
George maybe doesn’t realize up here in the rust belt the torch is sometimes your best friend. Also, time is money. Up in these parts we can cut a rusty small castle nut off without hurting anything but the nut. Even the threads survive.
The cutoff wheel is a good second choice, especially if crank is still in the block Go most the way and then use a cold chisel as a wedge to finish the dirty deed. All previous disclaimers apply, AND be sure to spray the sparks at the neighbors cat!

Re: Crank gear removal
Take the crank out and press the gear off. Usually doesn’t take much pressure. 1 to 2 tons maybe.

Re: Crank gear removal
If its like a VW crankshaft you can remove the crankshaft stand it on end gear down and heat the gear while rotating the crank and the gear will fall off.
how's that for a short sentence?

Re: Crank gear removal
Just as Adam said remove the crank and use a press to remove the gear. Plus you will need the press to put a gear back on. Bill

Re: Crank gear removal
It still being in the block really changes my opinion and quick advice. Never thought that far ahead. I’ll crawl back in my hole now.

Re: Crank gear removal
Yeah, Tim maybe didn’t realize the crank is still in the block so the heat necessary to foolishly cut the crank gear would totally turn #1 main to toast. Thank you Adam and Bill for confirming my initial advice.

Re: Crank gear removal
George, not an excuse, but I assumed it was the cranks the OP offered a week back. They were loose cranks and he offered to sandblast them. Those would be perfect candidates for my removal method, with absolutely no damage done to the crank.

Re: Crank gear removal
I have to ask! Did you use a cheater on the wrench? I have some 1 and 2” pipe in different lengths I use when I have to. Glad you got it done without breaking anything!
