Removing PTO drama...HELP!

[evilnss]

So i bought my new PTO and i put the role into the cylinder (One closest to the PTO) I got a wrench and i'm trying to turn the PTO counter-Clockwise, as if i was standing at the back of the boat. Am I turning the PTO The right way... Should I be trying to turn it towards the driver seat or the passenger seat?

Thanks,
John

You want to turn anti-clockwise, but before you twist your backbone you should add a chain over the motor mounting rubbers or you will tear those off - make some kind of bracket if you do not have the longer bolts needed to hold down the motor tight.

The motor is still in the boat.

Got the PTO off. The key is to get that hard yellow nylon rope from Home Depot or Lowes, I got 5 feet and just shoved it in there. and then a pipe wrench with a 18" piece of pipe on top of the 14" wrench and it will spin right off after a few good tugs.

Glad to hear you got it off, a couple drops of blue loktite from almost any auto parts store will insure the new one will not vibrate loose - the common number included in the parts store number is 242, it is called medium strength thread locker, you will use it on many marine bolts.

Hey VooDoo,

How do you go about tightening it down? I put the new PTO on and turned it until the motor would start rotating. When the boat is running it spins clockwise, so it really isn't possible to vibrate loose is it?

Torque....

Hey VooDoo,

There might be a torque on this, but I've never used one. You need to put that rope back in your cylinder when you tighten it down. You also need to use the Loctite (or other thread locker) to keep it tight. That's why you had such a hard time breaking it loose. My reply to your request was coming, till I saw you figured it out. I use a pipe wrench too. I usually take out the small zirc fitting so I don't damage it.

Your also correct in your thinking about the way it stays on. Like the way a saw blade stays on a circular saw. The counter rotation of the direction you put it on, will keep it from coming off.:cheers:

I use the rope again like snipe mentioned, what about deceleration load? Even though it is under some pressure to stay tight it can still vibrate and with harmonics of the metal could actually walk right off the crank nose - use a drop of blue and you will be sure. I have a driveshaft with a bad end I use for this tool, I heated and folded it into a spline torque bar, I would guess this gets tightened to 60ft lbs based on my bald power pulling my homeade pump repair tool.

Thread sealant...

Yes, def use thread sealant and that torque sounds about right. I'd think it's somewhere between 40 to 60 ft.lbs. Though, like you, I have a pipe wrench, not the special tool they want you to buy. But, even with that special tool, I don't think there is a way to torque it, unless you come from the front at the magneto flywheel. But, that would mean the torque on the PTO is less than that of the flywheel.....

I'll try and remember this for tomorrow and look it up.......:cheers:
