36" Deck Stacked Pulley

[1987_WHEEHORSE312 82]

Hey guys! So I was looking over my 36" side discharge deck and noticed that the stacked drive pulley was loose. It is a Double D style, and it seems the center bore is just a tad bigger on pulley. I have confirmed the spindle size is 5/8". I was talking to someone on Facebook and they speculated it may not even be the correct pulley on there and that someone did a garage hack just to sell it. There is no plate or stamp indicating any kind of model number on the deck even though the deck is in good shape.  I was wondering if someone has a replacement I can buy or may know a part number for a website to a pulley I can buy. Here are photos of all the measurements you guys will need.  The pulley with the smaller groove is the pulley that runs the belt on the deck.

Here are the possible deck models using the 5/8" x 3/4" double-D holes unless the spindle assemblies have been replaced with older assemblies than the deck.

You do have 3 spindle assemblies on this side discharge deck? Never listed for the 312-8 - rear discharge only.

A 2-spindle 37" side discharge deck was recommended.

Not sure if this is the original deck to the tractor. It was on it when I got the tractor. Here is a photo of the deck. I measured 36 inches across.

The folks above have you covered.

Delighted to see another user of a dual-scale tape measure!

At first I was put off that the metric was on “the bottom” but I’ve been warming up to it. I’m forcing myself to use metric whenever I can. Old dog; new(-ish) trick.

I actually use tenths of a foot at work!

As a consultant, years ago, I set up software for payroll and benefits systems. One agricultural client used a lunar cycle calendar for payroll, i.e. he paid workers on half- and full-moon days. He got what he wanted! (I learned later that this was a common system in the UK at one time.)

@  # 87 wheehorsE312 ,  done a number of decks , a bearing lubrication  UPGRADE , on every related bearing  . including mule drive   . pto detailing  makes a magical difference of function . also add a  flat belt bounce eliminator , pulley  , decks easily spin by hand ,  original set up  will  fail again , pete
