Navistar, a leading manufacturer of commercial trucks, has issued a recall for certain International trucks manufactured between 2018 and 2020. The recall affects trucks with a potential connecting rod problem, which could result in engine failure and an increased risk of crashes. However, Navistar also announced that the problem could be resolved with a quick software fix.
If you own an International truck or fleet, it's vital to understand the issue and take the necessary steps to ensure your truck is safe to operate. In this blog, we'll take a closer look at the recall, what causes a connecting rod problem and how it is fixed. We'll also explore the role of connecting rods in your truck's engine and why they are essential to maintaining its performance.
Connecting Rods: The Basics
Before diving into the recall, let's first review what connecting rods are and what they do. Connecting rods, also referred to as con rods, are a critical component of an engine's crankshaft assembly. As the name suggests, these rods connect the crankshaft to the pistons within the engine block.
Their primary function is to transfer the force of the pistons moving up and down in the cylinders to the crankshaft, which ultimately converts this linear motion into rotational motion. Simply put, connecting rods are responsible for transforming the reciprocating motion of the pistons into rotary motion, which powers the engine and propels the vehicle.
What Causes a Connecting Rod Problem?
Connecting rods are incredibly durable and designed to withstand significant stress and loads. However, they may fail for several reasons, including:
- Overloading or revving of the engine beyond its limits
- Poor maintenance and lubrication of the engine
- Wear and tear due to the age and mileage of the engine
- Manufacturing defects or design flaws
When a connecting rod fails, it can cause catastrophic damage to the engine, including bent or broken rods, damaged pistons, and even engine block cracks. This may lead to an immediate shutdown of the engine, risking the safety of the driver and passengers.
Navistar's Recall for Connecting Rod Problem
In August 2021, Navistar issued a recall notice for several models of its 2018-20 International trucks with A26 engines. The recall affects more than 4,300 vehicles in the United States and Canada. According to the notice, some of the trucks' connecting rod bolts may not have been properly tightened during assembly, which could result in an engine failure or loss of power while driving.
However, Navistar noted that the issue could be resolved with a software update that would alert the driver if there is a risk of a connecting rod failure. The fix would also limit the engine's power to prevent further damage until repairs or maintenance can be performed.
