32” Heavy Duty Tiller for Simplicity 725

Recommended Posts

dince

Can anyone tell me the diameter of the idler (pulley) on a 32” Tiller, please?  It’ a while since I dismantled mine, and I’m trying to work out where the three idlers I have are meant to go.  One for the tiller and two for the 725 Garden Tractor.  I’m much better at dismantling than I am at re-assembling!

Bill725, many thanks for your reply and advice, however, I’m a bit “stumped”!  Do you mean the Simplicity Manufacturers website, which I cannot find, or one of the other user group websites, like Facebook?

Sometimes you can go on a "treasure hunt" to find the part info you need.  I use Jack's Small Engine old search box found here:

https://www.jackssmallengines.com/searchdb2.cfm

Enter the old part number and it will give you extra info like the diameter of pulleys (sometimes).  

If not, it will show the pulley on a 1" square grid so you can get some idea of the diameter.  

For instance, for Idler Pulley "V" for your tiller, the original item number was 108386 (from the combined operator/parts manual) enter that number at Jack's and you'll get:

2108386sm.jpg

You'll find the latest part number is 2108386SM and sometimes you'll get an alternative aftermarket match(s).  So for the Stens alternate (#280214) you'll see this:

280214.jpg

And under the "specifications" tab you'll fine this:

heavy-duty-flat-idler-measurement.jpg

Height 1"
ID 3/8"
Material Steel
A 3 3/4"
B 3 1/4"
C 3/8"
E 7/32"
F 7/32"
H N/A
K 3/4"
V 1"

So you notice the ODs are different by about an inch.  But many time the lip of OEM Simplicity idlers are higher than the aftermarket equivalents.  So the effective diameter (when the belt rides) is probably about 3-1/4" on the Simplicity pulley.  

Happy searching!

PhanDad, what a great lesson!  Thank you indeed.  Unfortunately, for the US manufacturing economy, I will seek out my needs here in Australia.  The US Postal Service usually charges more than the parts cost!

I understand that for sure.  

It's all about getting info, hopefully correct, and matching it up as best you can with those mealymeters you use.  666

Now, PhanDad, you have struck me with a new word!  I don’t know as to whether I should be elated, or offended!!!  LOL!

What are “mealymeters” that I (might) use?

I've never seen any personally, but I understand you get 25.4 mealymeters per inch.

Ah yes! Now I’m with you!  That would be a metric inch you are referring to!  I think you ought be careful, because when I found my 725 Tractor, it had UNC, UNF, metric and Whitworth nuts and bolts on it.  Must have on it when it sailed down to Aus!  The PO, an Australian, can’t have changed any original nuts and bolts.  How do I know, you might well ask?  Because, there was nothing held on with hay string or wire, the typical fasteners an Aussie would use!

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
