Not real pretty but is a start - Wheel Horse part number to Woodruff key

Folks...

 

I'm trying to find a proper key for 6 and 8 speed input shafts. 

The shafts are 5/8" diameter. 

I have a key from a mid 70s 8 speed here. Appears to be stepped??

 

Looks like it should be 5/32 but there's several.  

How can I narrow it down?

I'm not sure Eric. I was thinking 3/16" on the 5/8" shaft. I'm not sure what you mean by stepped.

937221 key is a Woodruff 6 and the size is 5/32" x 5/8".

The key is listed as a Hi Pro type in the parts lists and that is what you are describing. The extended ends prevent the key from trying to rotate when installing.

I do not know if the #6 is a standard key or one with the extended ends making it a Hi Pro style.

Here's a link to what we have.

I looked up the key for my 2005 8 speed. P/N 937108 which is 1/4" x 1 3/8" which likely is correct. I'm comfortable in saying that there isn't any of those stepped keys on the tractor.

Which makes me wonder...

Is there a specific point or need to be extension other than ease of installation?

I have no clue. I've never seen one before.

I’ve searched and searched here and the net and can’t find my answer. I’m looking for the axle woodruff key size for a 1966 model 856 with the 4 speed transmission. My older sons seems to have lost a key out of the axle/hub while plowing a figure 8 race track in my back yard 🤦🏼‍♂️. I see the 8 speed size on here numerous times just nothing for a 4 speed.

That would be a # 15 Woodruff key which is 1/4" thick and 1" long. any hardware store should have them.

Yep #15 real common horse key.  I go through alot of them. Found a deal on them once on fleabay ... 20 for 10 bucks but all gone now. Then there is the  

jungle assortment kits.

I asked myself that and him. Also especially since the axle looks good too. I snagged some from

work. Turns out we have a whole woodruff key drawer in our hardware section. As my boss would say “the perks of this job are what ever you make of it”. Having hardware handy to grab from and borrowing equipment sure does have its bonuses

What's chances that it didn't have a key in there for years and just recently loosened?

It could very well of been like that. There’s also the chance that the tire did come off and he didn’t own up to it. I would hope he would have told me so we could fix the situation if it had a issue

[WHX?? 49,129]

I'm just not seeing how the key can go MIA without pulling the hub.
