What Happens When a Wrist Pin Bearing Spins
A spun wrist pin bearing is a serious internal failure that can lead to catastrophic engine damage. The wrist pin connects the piston to the connecting rod, allowing the piston to pivot during combustion. The bearing—usually a bushing or sleeve—ensures smooth rotation and distributes load evenly.
When the bearing spins inside the rod eye:

• It disrupts oil flow, causing heat buildup
  
• It can seize the wrist pin, locking piston movement
  
• It may score the piston and liner walls
  
• It often cracks the liner and leaks coolant into the oil pan
  

• Improper Installation: If the bearing is misaligned during rebuild, oil ports may be blocked, starving the pin of lubrication.
  
• Plugged Piston Coolers: These nozzles spray oil onto the underside of the piston to dissipate heat. If clogged, the piston overheats, increasing stress on the wrist pin.
  
• Material Fatigue: Over time, connecting rods and bushings can degrade, especially if subjected to high loads or poor maintenance.
  
• Coolant Contamination: Cracked liners allow coolant into the oil system, reducing lubrication quality and accelerating wear.
  

• Wrist Pin (Gudgeon Pin): A hardened steel pin that connects the piston to the connecting rod.
  
• Spun Bearing: A bearing that has rotated out of its seat, losing its ability to function properly.
  
• Piston Cooler Nozzle: An oil jet that sprays the underside of the piston to reduce thermal stress.
  
• Liner: A replaceable cylinder sleeve that houses the piston and maintains compression.
  

• Drop the oil pan and inspect for coolant contamination and metal shavings
  
• Remove rod caps and check for play in each connecting rod
  
• Pull the affected piston and inspect the wrist pin for discoloration or scoring
  
• Check liner height and integrity—cracks at the bottom often indicate coolant leaks
  
• Inspect piston cooler nozzles for clogging or brittleness
  

• Replace the damaged piston, rod, liner, and wrist pin bearing
  
• Replace all six piston cooler nozzles if they are nylon—these degrade over time
  
• Clean oil rifle passages to ensure unobstructed flow
  
• Verify liner height to prevent compression imbalance
  
• Use high-quality bearings and ensure proper alignment during installation
  

• Always inspect piston coolers during rebuilds
  
• Replace nylon nozzles with steel upgrades if available
  
• Use plastigage to verify bearing clearance
  
• Monitor oil pressure and temperature regularly
  
• Train technicians on proper bushing alignment techniques

This article delves into the typical causes of lift axle malfunctions, provides troubleshooting tips, and offers advice on ensuring optimal performance from these essential parts.
What is a Lift Axle?
A lift axle is an extra axle on a vehicle, typically used in trucks, trailers, and certain types of construction equipment, which can be raised or lowered depending on the load. The purpose of the lift axle is to increase the vehicle’s carrying capacity by adding additional support when needed. By lifting the axle off the ground when not in use, it helps improve fuel efficiency and reduce unnecessary wear on tires.
These axles are most commonly found in tandem or triple axle trailers and are used to distribute the weight more evenly across the vehicle when hauling heavy loads.
How Lift Axles Work
Lift axles work through a hydraulic or air suspension system that can raise or lower the axle depending on the weight being carried. The system typically includes a lift mechanism that is controlled either by the driver or an automatic load-sensing system that adjusts based on the weight in the trailer.

• Air Suspension: The lift axle is often controlled using an airbag, which inflates to raise the axle and deflates to lower it. Air suspension systems are popular because they provide a smoother ride and better load distribution.
  
• Hydraulic Suspension: In some vehicles, a hydraulic lift mechanism is used to raise and lower the axle. This system is often found in construction equipment and larger vehicles where lifting capacity is crucial.
  

• Symptoms: You may notice that the axle does not lift at all or it takes longer than usual for the axle to lift when activated. Additionally, the air compressor might run more frequently, indicating a lack of proper air pressure.
  
• Solution: Inspect the air lines and airbag for leaks. A soapy water solution can be used to locate leaks by applying it to the lines and watching for bubbles. If a leak is found, replace or repair the damaged section of the air system.
  

• Symptoms: The axle might raise or lower only partially, or fail to respond to the control inputs. In more severe cases, the axle could become stuck in one position.
  
• Solution: Inspect the control valve for any obstructions or damage. It may need cleaning or replacement if the valve is faulty. In some cases, recalibrating the valve can resolve the issue.
  

• Symptoms: The axle may fail to lift or lower, or it may get stuck in one position. Hydraulic systems can lose power if there’s a problem with the fluid levels or if the pump isn’t functioning correctly.
  
• Solution: Check the hydraulic fluid levels and inspect for leaks. Make sure the pump is functioning, and if there is an electrical control system, verify that all connections are intact and the system is powered properly.
  

• Symptoms: The axle may be slow to lift, uneven in its movement, or may fail to engage or disengage altogether.
  
• Solution: Inspect the mechanical components for wear or damage. Look for broken springs, worn-out lifting arms, or issues with the pivot points. In some cases, lubrication of the moving parts can solve minor friction issues, but severe damage may require component replacement.
  

• Symptoms: The lift axle may sag or appear deformed under load. In extreme cases, it might fail to lift or lower properly.
  
• Solution: Always ensure that the load is within the specified limits for the vehicle. Regularly check the load distribution to ensure that the lift axle is only being used when necessary and that it is not being overburdened.
  

• Regular Inspections: Perform routine checks on the air suspension lines, valves, and control mechanisms to ensure everything is functioning properly.
  
• Keep Air and Hydraulic Systems Clean: Prevent contamination by replacing air filters regularly and ensuring the hydraulic fluid is clean and at the correct level.
  
• Lubrication: Apply lubricants to the moving parts, such as the lifting arms and joints, to reduce wear and tear.
  
• Avoid Overloading: Follow the manufacturer's guidelines on maximum load capacity to prevent strain on the lift axle.
