Product Details

The Dayco 5100688 is a heavy-duty poly-rib serpentine belt engineered specifically for commercial trucks, buses, and heavy-duty vehicles with multiple accessories. This 68.75-inch belt features 10 ribs with a 1.38-inch width and straight rib profile, designed to power essential systems including alternators, air conditioning compressors, power steering pumps, and water pumps on heavy-duty diesel engines.

Key Features:

  • EPDM (Ethylene Propylene Diene Monomer) construction for superior heat resistance up to 266°F (130°C)
  • Specially treated cord reinforcement resists stretching and ensures length and tension stability throughout belt life
  • Engineered for high torque and high power pulse applications common in heavy-duty diesel drives
  • Grooved rib design runs cooler, quieter, and provides reduced slippage compared to standard belts
  • Compliant with SAE J1459 and SAE J2432 specifications for heavy-duty performance
  • Designed to resist cracking and wear under extreme temperature ranges and demanding operating conditions

This heavy-duty serpentine belt is manufactured to OE quality standards and provides reliable, long-lasting performance in the harshest commercial vehicle applications. The advanced EPDM compound delivers resistance, reliability, low noise operation, and extended service life on heavy-duty diesel engine drives with multiple accessory systems.

Specifications: Length: 68.75 inches | Width: 1.38 inches | Rib Count: 10 | Profile: Straight Rib | Metric Designation: 10PK1745

Shipping was a little expensive but overall very happy

A+

Super ez to apply low payments great products

...

Excellent.

Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

Very easy and quick ordering process, so far so good. Completely satisfied with the product and the speed of shipment. Would gladly do business again with Autoplicity.

Hope it fits!

Better prices and even better service. Will do business with again.

Great communication, lowest price I could find anywhere, and quick shipping with a tracking number. What more could you ask for. 2nd time dealing with them and still impressed! order# 6935
