Any tips on driveline pin install? Split tractor again or try to do it in one piece?

I ask because someone warned me to support the end of the hydro when pinning the flex disc couple on it...

I would be guessing here because I don't have anything available to look at, but I am thinking that you could unbolt the engine and slide it forward enough to dis-engage it from the engine hub, then support the driveshaft from below, perhaps with a length of 2 by 4. If there is room to hammer, that might work.

I wouldn't split the tractor again, I'd take the 4 bolts out holding the engine in and slide it forward to give you a little room to work. Make sure you support the driveshaft with a block of wood or something so it doesn't get bent will installing the pin.

When it is in, it goes through the groove in the pivot pin and keeps the pivot pin from coming out. Alot of rust may have formed on the pivot pin, so soak it real good with penetrating oil before trying to tap it out. The part in the picture labled "retainer" is where your "O" ring is. Once you get all the external parts off nothing holds it in but it can be a bitcz to get out. Once again lots of penetrating oil and prying.

These are the parts in ironman's picture. Original parts on left, replacement on right.

That would work although if you get that far, it's only two more bolts to take it out.

One end of the driveshaft pin hole is reamed on size so it's easier to start the drive pin. "Murphy" makes sure that will be on the bottom first try

It started ok, but I'm using a 5 pound hammer and a block of wood and the pin is mushrooming. I just removed the drive shaft and will use vise at work to press it in...

Need another pin?

Are those pins hardened?

No, not hardened but a strong steel alloy.

They original ones I have never mushroomed,they must be harder.

The original one I hammered out broke like glass, Jeff's does seem softer. I'll keep an eye on it and report back after a few weekends of mowing. Also, I got it back together and fired it up, no more noise!
