One of the two belts was intact in my sharpener.

I measured it and counted the teeth and believe I have now ordered the replacement drive belt for the sears craftman sharpener 319.190710 or 919071 or 319190710 seems all are the numbers i could find.

the part # i ordered is a 100XL037

timing belt with 50 teeth 3/8 inches wide 1/5". remember to order 2 of them.

I hope once I receive it I will remember to post a confirmation on this site that it was correct. if i do not please remind me to if you need definitive.

I was wondering if the timing belt you ordered worked in the Sears sharpener?

part number 100XL037 1/5 pitch (XL) timing belt

you will need 2 of them, price was $4.21 a belt

very easy to change out 1 on a scale of 10 for difficulty. you have to know how to operate a screwdriver.
