Craftsman 26hp GT, Hydro, 48in deck, electric pto. I checked it(26hpELS) out and the left bank is failing fast. And the right is not much better, pretty greasy and dirty too. So I bought a 30HP briggs to repower. The engine removal from the tractor was pretty easy, they attached the motor to a mounting plate, with 4 bolts attaching that to the frame. How do you get the PTO off? I can't replace the motor with the new one until I get the PTO off the shaft so I can remove the engine mount plate. I got the long bolt out easy enough with a socket wrench locking the crank nut, and there is minimal rust visible. I tried smacking it with a hammer but its frozen. Any Ideas? HELP!

Penetrating oil on the shaft what you can reach of it. may be able to hang the engine by the pto, to use gravity to your advantage.

Turn the engine upside down and thread the long bolt back into the crank halfway, leave off any washers. Hang the engine
with a chain or rope from the ceiling, round the clutch, then with a hammer, tap on the nut, and squirt lube into the hole and
keep tapping, it will break loose. If not, you can move up to smacking, but if you smack too hard, you will need to get a new bolt.
I picked it up by the pto to move it into position. Then I tried to suspend it by the pto, the strap wouldn't budge so I jerked on the strap while pulling down and then it just let go narrowly missing my toes. Go figure. Thanks for the advice guys.
The PTO is acting up and I can't fix it. I connected up everything right, but the PTO seems to spin when I engage it (switch) It tore the wires out of the connector, so I thought it may have been slack in the wires getting in the way, and I installed blade connectors and tried again, it tore the wires out of the PTO from spinning. I understand the idea behind the spinning shaft and the magnetic clutch engaging the deck drive pulley, but I don't get why it would spin. Any Idea's out there? Honestly the PTO was the nicest thing under the hood before the new engine. Help!

There should be a pin, rod, plate that the clutch bumps up to to prevent spinning the clutch. You are missing what ever it is that keeps the clutch from spinning with the crankshaft, or didn't get it installed correctly to capture the clutch.

Yeah, like he said.... There is usually a bracket with a notch to keep the clutch from spinning, but does allow for @ 1/2" of play.
OK! now I know what to look for anyway. After reading the responses, I looked at the exploded view. I think I may have put the thick washers on top and not under the idler plate. OOPS
OK, So I got the plate installed correctly and clutch working as designed. then the 'v'idler pulley closest to the motor seized up. I tore it all down and replaced the bad pulley and installed a new drive belt, which by the way is a real chore. I put it all back together and let the wife take it out to mow the front yard- 30 minutes in there was a massive blowout of oil and smoke from the right lower side. we shut it down immediately. the motor didn't leak out any more oil after shut down that I could see, and still says ADD. So I guess it didn't loose that much oil, but still what a mess! Could it have been crankcase pressure not venting? Any Ideas?
Yes, Brand new-30 minute run time, also, I finally gained the nerve today to look at it and not shoot it and found that it's seized up, but no holes in the block, no pieces missing, but a really nasty burnt oil/rubber smell. Any Ideas?
Ok, Sorry, it's been awhile, between work and the wife in the hospital I haven't even looked at it. I need to know what manual would guide me through a tear-down. I went to B&S website and they don't list a manual for the (30HP) 49M800 series engines. It is seized, and still has oil in it(oil @ add mark) there are no visible holes or cracks in the block. And it looks like Permatex (not gasket material) sticking out of the sump-brown semi-transparent.
OK, no problem already did that. One said they'd get to it in a couple of months, because they were busy with 'real' work. And the other one 30 miles away actually looked at it before refusing to honor the warranty because the engine fan has a Husqvarna icon on it- and its installed in a craftsman GT tractor. Yes he was serious, an yes I have given up, I'll tear it down and fix it myself.
