Dayton V-Belt on AHS - Replaced After 6 Years

Finally replaced the old cracked Belt, greased the bearings and cleaned and lubed the chain. Much quieter now.

Wow, that belt could have let go at any time. Good thing you addressed it when you did!!!

When buying belts I go for the green agriculture belt, they are super tough and only a little more.

Anyone try a polyurethane belt supposedly they don't crack or dry out?

Heat will eat them so look at the applcation closely before choosing a poly belt. Green ag belts take a pounding like a champ.

That belt is cooked! How long was it in service?

Is the 4L250 the same size V-Belt that the AHS S130 uses?

Given the size difference between the two boilers, it is very unlikely the same.

If 4L250 means 25" in length, they are probably the same belt.

When you say green, do you mean V-Belts such as the Gates Green Stripe series?

Not sure, their Green Stripe are truck/bus belts IIRC. They have a Power Rated that has Aramid fiber, I think that is their HD ag belt.

It's written on the belt what does yours say?

My boiler is already prepped for winter. I will have to remember to take the belt guard off and look at it when its time for its spring cleaning and lube.

I did look it up on Grainger, and the Dayton 4L250 is 25" long. It is also 1/2" wide on the outside, 5/16" wide on the inside, and I believe 0.31" in thickness (this later dimension not being mentioned on Grainger).

The AHS part number (as seen on the AHS parts website) for the S130 belt is 200-326. Their part number for the S260 belt is 200-327. This would imply that they do not use the same belt.

The two use different belts.
