TIP on removing PTO flywheel?
So I had a driveshaft/PTO spline failure on a 97 GTI. Ordered parts...trying to get the flywheel off without pulling motor.
I have a universal puller that I mounted to the mag flywheel to keep it from spinning. Can't get the PTO flywheel to budge. Threw a little heat to it but hate putting a torch in there.
Any other ideas?

First thing is you cant hold on to one end of crank and loosen the other. You will twist it out of index, then screwed until having it straightened. Those flywheels are on extremely tight. Fortunately the times I have removed them is when motor is torn down so I can secure crank in a very big vice. Then it still takes a 3/4" break over bar and 4 ft cheater.

Great...guess I'll be pulling the motor then.
Wonder why the shop manual even tells you to do it that way?

Might not be the best way to remove it but the last one I did was on there very tight. I took out the spark plug and put a rope in there to keep the engine from turning over and used a 48 inch pipe wrench on the pto. That took it right off. I got worried that using a torch on the pto would mess up the crank seal.

Yea, did the rope trick AND heated the PTO. Still wouldn't budge
The motor is out - gonna try one more time heating it evenly + rope. Then it's splitsville

Heat up the PTO, use a 4ft pipe on a pipe wrench on the outside of the PTO, with lots of pull on the pipe wrench have some one use a good powerful impact gun on the impeller removal tool at the same time.
I had one that was a PITA, a 4ft pipe would not budge it but the pipe and impact at the same time popped it right off.

He can't use prop tool. The spline are destroyed. Big vice and heat. That's how I do all mine.

@ Joe - do you ever thrash a seal from too much heat? I figure I could get even heat with motor out. Are these red loctited?
This is the second motor in it(previous owner)

Usually I'm taking that off to replace the seal anyway so trashing the seal never mattered for me. Being the balancer goes around the seal you're better off changing it no matter what.

Old pro showed me it better to put a whole bunch heat in one spot as fast as you can. It easily budged something I couldn't by doing it evenly. Better expansion because less transfer to what you don't want to. All can debate it if they want to been doing it ever since and never looked back.
