Bolt
 

Can some tell me the name of the bolt that is used to hold the spindle on to the deck on the old decks. The head is flat and they have grooves around the bolt that will hold the bolt from turning as you put a nut on it. Thanks for any help in advance. Have a great night.
Bob

They are called carriage bolts

The flat head bolts with the square under the head are called “plow share bolts”.
Carriage bolts have a larger domed head.

The bolts I am talking about have like splines under a slit curved head.

Cast iron spindles?

Ribbed Elevator Bolts

If this is not what you want look around www.mcmaster.com they offer a huge selection of bolts and screws. Prime fasteners has a great selection as well.

I think you may have to post a photo

Sounds like he is describing a bolt like a lug stud on a hub or Axle that holds the wheel on.
Those a have spline sort of under the bolt head.
The head cam be somewhat flat like a plow bolt or domed like a carriage bolt.
Yes please post a pix so we can help further, as OZ suggested.:beerchug:

They are the square neck flat head plow bolts as athomas posted the link to up above.
You need the flat heads because the pulleys, specifically the center pulley, sit down so close to the top of the spindle housing that they would rub anything sticking up too high.

Ok fellow members. I may be leading you on a wild goose chase. I do not have a picture but was relying on my memory. As most of you know by now, my memory is not worth 2 cents. A few years ago I had to cut bolts off my 38" deck that held the spindles on. More than likely the bolts were probably carriage bolts and had no splines. I am so sorry . Thanks to all that read and responded trying to help. Have a great day.

PS Please do not ban me!!!!!

Once again, parts book to the rescue here!

IH-21860-R1
BOLT, 3/8 x 7/8 ZND SQ-W CRG

That bolt is a regular carrage bolt for the waterpump style spindle.

For the cast spindle housing you need the plow bolt that is tapered to fit down into the hole for the square part to lock in.

Left handed hydrospanners.

You might be thinking of a serrated bolt. Flat head with serrations around the circumference to keep it from turning. Not sure for what application it was used, but from what you described, this was the first thing I thought of. I just happened to find a picture of one for you to check out.

What he said ^

The parts book doesn't lie! Not saying a previous owner didn't use some hardware he found at work, on the ground, or at Ace :biggrin2:

I checked the parts manual for decks and did not find the bolts listed. Today I went back to Implements, IHCPE-2B Parts manual for 38" decks , 3 spindle. Still could not see the bolts listed. Either I am at the wrong place or I am blind as a bat. Probably BOTH!!!!! Thanks for helping and have a great day.

The bolts you use depend on what spindles you have.
I pictured both types up above in post #13.
If your spindle is the type with the yellow pulley, then you use the bolt also pictured in post #13. It is called a plow bolt, available on eBay, McMaster, etc.
If your spindle is the type with the silver pulley, you use regular ol' carriage bolts, available anywhere.

Ironman said it all! You have the options. Choose which one is appropriate for the spindles you have on your deck. Most everyone will agree that the parts book is "gospel". :biggrin2:

This ^^^ not sure why it's still in question :bigthink:

Just a follow up concerning "The Gospel"....
The bolts in question are not pictured, you have to look at the spindle parts for that info.
Note that both types are 3/8" NC x 1" long.
And don't bother trying to look up the bolt part numbers, they don't work.

What this boils down to (Mr Bob) is to use some common sense and choose the right bolt to fasten the spindles to the deck securely. This is not rocket science, nor do you have to be "MacGyver" to figure this out to get the job done! :bash2:

Sam Mac would probably tell you, "stick those bolts in there and tighten those suckers up 'til their nuts ain't comin' loose"! Enuf said!! Git-R-Done!! :beerchug:

The correct bolt for the cast type spindle housing is somewhat critical for two reasons:

1. The "plow" bolt sits down deep enough in the casting for the square part of the bolt to lock into the square part of the hole. A carriage bolt wont grab.

2. More importantly, the center spindle pulley extends out beyond the bolt locations and slides down quite low on the spindle shaft.
If carriage or hex head bolts are used, the bottom of the pulley will hit the heads of the bolts. When you tighten the pulley down it will not even spin. The plow bolts have flat heads, thus no problem.

So there is some rocket science involved.

Naw not rocket science, FARMER science!!
Dem plow bolts is gooder fer lotsa stuff :biggrin2:

Ok, Mr Bob...use the plow bolts (the right choice) and get it together! Have fun while you're at it!

I hate to say it but I can't remember what I was working on last December when I started this thread. Anyhoo, have a good laugh on me and thanks for all the advice and have a great day.

Mr Bob "Bolt"
 

As I get older, I figure if I can't remember something, it probably wasn't very important. Thanks for the conversation among the members and some laughs about the "bolts"!! :biggrin2:

Thread? what thread?
oh yes we was discussing sewin' a button on a winter coat.
and if Mercerized cotton was better than button and carpet thread.
I remember now :bigthink:

ol' George, you're a stitch! I like your sense of humor...:biggrin2:

Well I just remembered. I was working on a spare 38" deck that is stored under the building. Not going to pull it out from under the building until summer arrives. Sure glad you all have a good sense of humor. Not funny getting old. Have a great day.

Of all the things I've lost,I miss my memory the most.
But I'm sure it's in a safe place.

Many people admit that if they knew they were going to live so long, they would have taken care of themselves. No apologies for being old...you have probably forgotten more about Cub Cadets than many of us will ever know! One would be lucky to live to an advanced (not old) age...and from what I can tell, you guys are pretty lucky! :biggrin2:
