8N special pully bolt for loader

[vtfast]

Looking for the special bolt that holds the pully onto my crankshaft on my 8N, anybody know an alternate part number or bolt to use?
Wagner part number: 100-281FA, Special Bolt.

A 5/8x1 fine thread will work if you cut half the thickness of the head off.

That is kinda what I am possibly thinking as well. Grade 8 with washer and lock washer with locktite.

This is the best solution I have found. Inexpensive and super easy. The better solution is ditch that pulley and hub and use the Dearborn 192161
/192162 parts.and splined shaft

Did you turn the washer down? Also, the Dearborn pully and spacer, how does it bolt up? A bit vague on the installation. Look at a New Holland installation?

I will also use a universal joint attaching the pump and get rid of the coupler setup, just makes more sense.
The new pully should be here this week, will look at it and perhaps turn down my own adaptor and attach it if I can make it work.

I just went and looked these parts up, wish I had the information prior to ordering, I likely would have gone this direction. This would make it easier and far better setup, the biggest issue I see is the alignment shift that would be just part of the end result, doubtful it would be enough to make a big differance.

The washer is just a piece of round aluminum bar with a standard 82` countersink.

How are you going to eliminate the coupler?

The Dearborn style drive is cheaper and works better
