Detroit Diesel Series 60 14-Liter – Connecting Rod Section

The Detroit Diesel Series 60 14-liter engine stands as one of the most advanced and proven heavy-duty inline-six diesel engines of its era. Known for its combination of power, durability, and fuel efficiency, this engine remains a mainstay across long-haul trucking, construction, and industrial applications. Within its design, the connecting rod assembly serves a vital purpose—linking the pistons to the crankshaft and transferring the energy from combustion into mechanical rotation.

This section of the catalog focuses on connecting rods, bearings, and related components specifically for the Detroit Diesel Series 60 14-liter engine. Each item listed here is built or reconditioned to meet OEM fit and performance standards, ensuring proper lubrication, alignment, and long service life when used in professional engine rebuilds or in-frame repairs.

Detroit Diesel Series 60 Connecting Rod (Rebuilt, 1.70" Bearing Type)

This rebuilt connecting rod is engineered for Series 60 engines configured with 1.70-inch connecting rod bearings. These were commonly used in earlier versions of the 14-liter and some compatible variants.

Key Features:

• Rebuilt connecting rod for Series 60 engines.
  
  

• Inspected and restored to ensure proper alignment and performance.
  
  

• Compatible with 1.70" bearing width.
  
  

• Sold with a refundable core deposit.
  
  

When Replacement Is Needed:

• Audible knocking or vibration from the lower end.
  
  

• Visible bearing wear or oil film breakdown.
  
  

• Discoloration or scoring on connecting rod surfaces.
  
  

Maintaining a strong and correctly sized connecting rod is essential to prevent uneven loads on the crankshaft and ensure smooth operation across all six cylinders.

Connecting Rod Bearing Set – 1.70" Width, Standard Size

The standard 1.70-inch width bearing set supports optimal lubrication and rotation between the connecting rod and crankshaft. These bearings restore proper oil film thickness and load distribution in the Series 60 engine.

Specifications:

• Standard-size, narrow-width bearings.
  
  

• One large lubrication hole for consistent oil delivery.
  
  

• Tri-metal design for wear resistance and strength.
  
  

Replacement Signs:

• Metallic particles in oil filter or sump.
  
  

• Uneven or scored bearing surfaces.
  
  

• Low oil pressure or engine noise at idle.
  
  

These bearings are ideal for engines using the early-style narrow connecting rods.

Connecting Rod Bearings – Standard Wide, 1.70" Width

This bearing option provides a slightly wider load surface while maintaining the same 1.70-inch journal width. The additional contact area supports better wear resistance and longevity.

Highlights:

• Standard wide bearings for improved oil film stability.
  
  

• OEM-equivalent fit and finish.
  
  

• Designed for smooth oil distribution under sustained load.
  
  

Maintenance Notes:
Replace bearings at the first sign of uneven wear or material flaking. Doing so ensures steady crankshaft support and helps reduce vibration at higher RPMs.

Detroit Diesel Series 60 Connecting Rod (Rebuilt, 1.86" Bearing Type)

This rebuilt connecting rod fits later-model Series 60 14-liter engines that use the 1.86-inch connecting rod bearings. The larger bearing width provides greater surface area and improved load distribution for engines with higher torque output.

Key Features:

• Rebuilt and inspected for proper fit and function.
  
  

• Compatible with 1.86" wide bearing setups.
  
  

• Designed for the 14-liter Series 60 configuration.
  
  

• Sold with refundable core deposit.
  
  

Signs of Wear or Failure:

• Lower-end knock or rattle.
  
  

• Oil pressure drop at operating temperature.
  
  

• Discoloration or damage around the rod journal.
  
  

Replacing connecting rods as part of a rebuild ensures consistent balance and performance across all cylinders, especially in high-mileage or overhauled Series 60 engines.

Connecting Rod Bearing – 1.86" Width, Oversize

When a crankshaft journal has been reconditioned or shows measurable wear, oversize connecting rod bearings (0.254 mm) are required to maintain proper oil clearance.

Features:

• Oversize 0.254 mm for reground crankshafts.
  
  

• Two large lubrication holes for even oil flow.
  
  

• Maintains correct oil film strength under heavy load.
  
  

When to Replace:

• Visible wear-through on existing bearing material.
  
  

• Persistent oil pressure irregularities.
  
  

• Noticeable vibration at mid-range RPMs.
  
  

Proper oversize bearings help restore engine balance, preventing metal contact between the crankshaft and connecting rod during operation.

Detroit Diesel Series 60 Connecting Rod (Rebuilt, Standard Wide Bearing Type)

This rebuilt connecting rod fits Series 60 14-liter and compatible 12.7-liter configurations using the standard wide bearing design. Each rod is rebuilt and inspected to meet fitment and clearance requirements.

Key Features:

• Rebuilt and inspected connecting rod for Series 60.
  
  

• Compatible with standard wide bearings.
  
  

• Designed for stable crankshaft support.
  
  

• Includes refundable core deposit.
  
  

Replacement Indicators:

• Piston misalignment or loss of compression.
  
  

• Excessive bearing wear or discoloration.
  
  

• Rod distortion after engine overheating or oil starvation.
  
  

Replacing worn or fatigued rods ensures each cylinder maintains consistent balance and compression during combustion.

Standard Wide Connecting Rod Bearings – 1.86" Width

The standard-size 1.86-inch connecting rod bearings are the most common in later 14-liter Series 60 engines. These bearings feature two small lubrication holes, providing consistent oiling without over-bleeding pressure from the crankshaft gallery.

Specifications:

• Standard-size bearings (no machining required).
  
  

• Two-hole oiling configuration.
  
  

• OEM-equivalent fit and material quality.
  
  

When Replacement Is Required:

• Bearing pitting or scoring.
  
  

• Low oil pressure after rebuild.
  
  

• Uneven wear on the crankshaft journal surfaces.
  
  

Keeping the bearings in top condition ensures a smooth-running crankcase and extends the service interval between overhauls.

Connecting Rod Bushing – Detroit Diesel Series 60

The connecting rod bushing supports the piston pin at the upper end of the connecting rod. It ensures a secure, low-friction interface between the piston and rod assembly.

Features:

• High-quality bronze construction.
  
  

• Precisely machined for piston pin alignment.
  
  

• Compatible with all Series 60 connecting rod assemblies.
  
  

When to Replace:

• Piston pin looseness or upper-end noise.
  
  

• Discoloration or scoring on bushing surface.
  
  

• Uneven piston travel or movement in bore.
  
  

Replacing worn bushings maintains proper piston motion and reduces wear on cylinder walls and wrist pins.

Importance of Connecting Rod Maintenance in the Series 60 14-Liter

The connecting rod assembly is one of the most critical rotating components within the Detroit Diesel Series 60 14L. Excessive bearing clearance, rod distortion, or improper oil film thickness can lead to severe crankshaft damage or engine failure. Regular inspection, proper torque procedures, and timely replacement of worn components keep the lower end of the engine reliable and efficient.

Maintenance Tips:

• Replace rod bolts when reusing rods during overhaul.
  
  

• Always check bearing clearance with plastigage or micrometer tools.
  
  

• Inspect rod bushings whenever piston pins are replaced.
  
  

• Maintain clean oil systems to reduce wear on bearing surfaces.
  
  

Properly maintained connecting rods ensure that combustion energy is transmitted efficiently, minimizing mechanical loss and maximizing engine longevity.
