Needing info for mower belt on Murray 40702x92F

[MarcStump]

Broke a belt on my brother-in-laws old Murray he purchased at an auction. Belt seemed too big, slipped a lot and finally broke. I can't find a lot of information on these old Murrays, and came across this forum.
the model number is listed as 40702x92F
the date of manufacture code is 94304-002207
Briggs and Stratton are no longer supporting these older Murrays, and I know the place to go for info is to people like some of you that own these old workhorses.
Can anyone give me a clue as to the numbers on the tag? If I have the model number maybe i can figure out the size belt.
Thanks.

And note the deck belt is listed as "Wedge" this is a specific belt that is nearly twice as deep as a standard section belt and fitting a standard belt will wreck the pulleys.

I hate to resurrect this old thread, but I got a "gift" of this same 40702x92F Model 95081 SN072118 from a neigbor with not a spot of rust on it... replaced the ignition and the solenoid and it fired right up. Got to looking at the belts and found this post.. More Thanks StarTech... for the part numbers.
I noticed the idler pulley for the drive belt is kind of burned through on one spot and has chewed up the drive belt a bit so was hoping someone might be able to point me towards a diagram or part number for a replacement?

I found this https://www.ereplacementparts.com/pulley-p-271044.html#product_reviews

And it looks pretty similar at 3.5 inches wide, but mine is eaten up a bit so I am not sure..

Any help is greatly appreciated as I can't seem to find a manual or parts diagram anywhere for this model..

Teach a man to fish & you feed him for life
SO measure the outside diameter of the dead pulley at the flanges
Measure the diameter of the surface the belt runs on
Measure the width between the flanges
Go to Rotary, Stns , Prime Line or Oregon web page & find the "pulleys by size " tables
Find one that is the same as yours
All of them are common off the shelf items
The only real difference is the mounting bushing in the bearing and the old one will push out if the new one is different .
Or go to a shop. you know the places where people stand behind counters and help people like you get replacement stuff they have no idea about
In this case you need an "engineering supply " or Chain & Sprocket store
Take your old one in and leave with new one .

Thanks.. did a lot of that.. and each replacement pulley I look at.. from Stens to China to Briggs n Stratton have slightly different dimensions than the one I have. And for whatever reason Jack's and PartSelect and Repairclinic don't have diagrams for 95 model mowers.. only 96 and above. Neither does Murray.

So after looking at the idler pulley on 96, 97 and 98 models with a 40 deck, I am going to just bet that the 95 was probably the same pulley and see if it matches up. I suppose it can't really matter that much if the diameter is 3.5 inches or 3.375 inches as long as the mounting bushing/bearing is the same size.

Nearly every idler runs a 6202 or 6203 bearing with a pressed in stand off bush
There are a mile of 3.5" diameter pulleys
Way back they were custom made with the bush forming the inner race and were double row of 1/16" balls
I still have some of them in stock
So while most sites list the heavy duty pulleys as having double row they are all single row deep balls
The flange diameter is not critical unless it will foul on a belt keeper
