Questions about this item

What pulley groove width matches the .5 in. top width of this 9451HD V-belt?

The belt's top width is .5 in., so it fits pulleys grooved for that same .5 in. dimension.

Can this 45.44 in. outside-length belt replace a shorter belt on the same drive?

No — the 45.44 in. outside length is fixed; a shorter belt would not seat correctly on the same pulley centres.

How do I confirm the 9451HD belt is seated properly after installation?

Check that the belt sits flush in each groove with no twist, then verify the 45.44 in. length allows correct tension per the engine manual.
