The Dayco 5100855 is an automotive multi-rib serpentine belt with 10 ribs and a 35.05 mm width, listed at a 2171.7 mm effective length. For a maintenance or purchasing professional, those two numbers are the starting point: rib count and profile must match the pulley grooves, and effective length must match the drive layout. This page gives you the exact figures to check against the belt you are replacing.

The 10-rib profile is the first thing to confirm. A serpentine belt with 10 ribs seats across ten grooves on each pulley, so the count has to agree with the drive it runs on. The 35.05 mm width is the corresponding figure for this profile. If the old belt is still on the machine, read the marking on the back and compare the rib count before anything else.

The second figure is length. This belt is listed at 2171.7 mm effective length, which is the dimension that determines whether it routes correctly around the pulleys and tensioner. Measure or read the old belt, then match both the profile and the length to the Dayco 5100855. The alias 10PK2170 also identifies this belt, so either number can be used when you request a quote.

When you contact us, send the part number, the rib count and the length you need. If you are unsure whether this is the right belt for the drive, a photo of the old belt marking and the pulley arrangement helps us confirm the match or suggest an equivalent.
