The Dayco 5040338 is an automotive multi-rib (serpentine) belt with 4 ribs, a width of 13.72 mm and an effective length of 860.04 mm. Before you fit this belt, inspect the drive and sheaves so the new belt runs true. MR Industrial Accessories supplies this belt to maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.
A worn serpentine belt often points to a problem elsewhere on the drive. Check each sheave for grooves, rust, nicks or embedded debris, and confirm that all pulleys spin freely and align correctly. Any misalignment or damaged sheave will shorten the life of a new belt, regardless of its quality.
Confirm the routing matches the drive layout and that the tensioner moves through its full range without binding. Clean the sheave grooves before installation. The Dayco 5040338 has 4 ribs, a width of 13.72 mm and an effective length of 860.04 mm, so it fits drives designed for that profile and length.
