So i been trying to remove this damn pan for TWO days!!
Ive done everything except heat.

Ive placed a 2x4 on the edge of it and wacked it with a hammer. Nothing

Ive placed a punch on pan and hit that with a hammer. Nothing

Ive tighten the drain nut all the way and tried to tighten it more hoping it spins the pan with it. Nothing.

Ive placed a steel bar directly on pan with a cloth in between. Nothing. Look at the end of the bar in the pics.
SOMEONE HELP!

Heat seems like a good idea to try next.
I like MAP gas but a propane torch should work fine, heat the sump cover up to no more than maybe 350 degrees. Then try with the two-by-four and a hammer again.
If you have a very tight fitting 27 mm 6 point socket you should try prying on the socket to pry it down.

Probably somebody just glued it on and the heat will really help you out.

Good luck!

I'm sure you will get it off but remember whatever you do don't pry it off!!!

Possibly carefully slide a very thin putty knife into the joint at the most.

I feel your pain. I just replaced the sump filter on a 79 Special. I am sure it had not been off before.

I put the bike on the centerstand, then strapped the back down against the rear tire to raise the front even more. I ran a long tie-down strap from the handlebars to my overhead door-opener brackets. They are very stout. Then I removed the front wheel to get better access. The forks were next on my list if I still wasn't successful. With the tire off I got a 6" 2x4 and a small sledge hammer and whacked it way harder than I thought was safe. Took several blows. It finally popped off.

Good luck!

I used an aged 2x4 and a small sledge hammer. I put the wood on the leading edge of the sump plate between the two forward mounting bolts. I really had to smack it hard! The bike was up on a Handy Lift so I wasn't on the ground. Still an awkward operation.

Part of the old gasket was left on the engine, part on the sump plate. Took me awhile to get all that off.

In retrospect I probably should have tried heat. I have an industrial heat gun I could have propped up and aimed at the sump plate and let it run for awhile.
 
My neighbor suggested a pry bar with a small block of wood and a bottle jack. Put the pry bar in the drain hole and use the wood as a fulcrum and the bottle jack to lever it up. Sounded dicey but you do what you have to. I still like heat.
 
If you damage the sump cover it's no big deal because they're cheap and plentiful.you're just really don't want to damage the bottom of the engine.
probably doesn't matter what direction you hit it from as long as you don't mash off any of the mounting points for the six screws that hold the cover on.
 
Yes, heat it up. And then I'd put the drain plug back in and hit against that with a block of wood. It's got 6 flat sides so you can come at it from 6 different directions.
 
I'm also assuming that you actually drained the engine oil first?

Just get a propane torch and play it around the edges of the cover for a few minutes.
It should be way too hot to touch.
An infrared thermometer comes in handy at times like this..

yea of course fluid ia drained
 
I've pretty much gotten away from using an open flame anymore. I just use a heat gun and on high, it gets stuff plenty hot.
 
If heat alone does not work, heat it up then spray it with cold water from a garden hose. The expansion and then contraction may loosen it off.
