Craftsman Lawn Tractor Drive Belt

I need to replace the drive belt on my Craftsman lawn tractor. The manual shows it to be part #140218 which cost $29 at Sears. The dimensions on the belt at the Sears website show it to be 84.5 x .490.

Dies anyone know if a 84" x .50" or a 85" x .50" belt will work? I can get one of these substantially cheaper than what Sears has the replacement for.

And the substantially cheaper belt will likely last substantially fewer hours. In many (but not all) cases with EHP manufactured Craftsman products I've had decent luck with Gates A-series belts and in your case you would want an A83 (1/2" x 85").

Puey,
just out of curiousity what do you know or think of Stens belts.

I have tried them on some older MTD's but usually wound up changing them out for OEM due to fit mainly.
Never had one in place long enough to determine wear.

The place I get parts said they re-spec'd some of their belts and I was wandering if they fit better on other models.

They are usually a good 10 to 15 bucks cheaper but I have still been too leary to venture one...

TIA

Many of the aftermarket belts come only in "full" inch lengths. You say yours calls for 84.5". Aftermarket usually will be either 84 or 85". No 1/2", 1/4",3/4" ect.
The other dimension is the angle of the "V" the belt is cut. Aftermarket cut the angle all the same. OEM may call for a 75* angle and the aftermarket only makes 60* angle. The angle is crutial to how deep in the pulley the belt sits.
Some equipment is more forgiving on size.
I have found that OEM belts are worth the extra few dollars as the fit better, work correct, and last a whole lot longer.
And the drive belt is not the easist to change so you do not want to be changing it very often.

One reason I asked about Stens is because they cross reference specific OEM part numbers for their replacement belts. I know they do for Craftsman/Sears part #'s as well as MTD.
I do agree that just matching up lenghts at NAPA with a Gates or similar belt does not give the best results.

ALL aftermarket companies have a cross reference. Their cross is usually the closest belt they have to that size. And many times they do work. An MTD belt #754-04122 specs are .312 x 90.24. The Stens crosses to a belt that is 1/2 x 90. The Stens is wider so it sits higher in the pulley which will make it a bit shorter. So this aftermarket belt actually becomes .42" shorter. This could be just short enough that it won't fully dis-engage. So my feeling is the extra $10 is well wrth it so the equipment will operate correctly and you will not have to change it as often.
Also, some aftermarket belts are just automotive belts that just can not take the strain and abuse that a lawn tractor gets.
