Complete Overhaul Kits for Detroit Diesel 8V71 Non-Turbo Engines

One-Piece Piston Overhaul Kit

For operators running a natural 8V71 with one-piece pistons, our overhaul kit includes everything needed to refresh the top and bottom ends of the engine. This kit is designed for simplicity, reliability, and straightforward installation.

Included Components:

• Pistons with rings matched to Detroit Diesel specifications

• Cylinder liners with shims and liner inserts

• Full gasket set including head gaskets, seals, and O-rings

• Main and rod bearings

• Thermostat and sealing components

• All supporting hardware required for a complete inframe rebuild

This kit is ideal for operators seeking a direct replacement solution that restores compression, fuel efficiency, and performance to OEM levels.

Crosshead (Two-Piece) Piston Overhaul Kit

Many Detroit Diesel 8V71 natural engines use the crosshead two-piece piston design, which allows for easier maintenance and longer piston skirt life. Our crosshead piston overhaul kit includes all the same essential wear components, but configured for the two-piece piston arrangement.

Key Benefits:

• Designed for high-hour engines in marine and industrial applications

• Provides maximum durability for continuous-duty operation

• Includes upgraded rings and liners for long-term reliability

Essential Tools and Supporting Components

No overhaul is complete without the correct tools and related components. Diesel Pro Power supplies not just overhaul kits, but also the precision-engineered parts and tools required for correct installation.

Cylinder Liner Puller

A vital tool for removing cylinder liners without damaging the engine block. Specifically designed for Series 71 engines, this puller ensures smooth extraction and speeds up rebuild time.

Liner Inserts and Shims

Both standard and oversize liner inserts are available for the 8V71. These ensure proper seating and fitment of the cylinder liners. Shims in precise thicknesses (.002 and beyond) allow for fine adjustments to liner height, which is critical for maintaining compression balance across all cylinders.

Gaskets and Seals for a Leak-Free Rebuild

Complete Gasket Kit for 8V71

A full gasket set is included with every overhaul kit. This ensures that every joint—cylinder head, crankcase, inspection covers, fuel connections, and coolant passages—are sealed properly.

Inspection Cover Gaskets

Inspection gaskets are small but critical components for Series V71 and V92 engines. These gaskets allow mechanics to reseal block inspection covers after checking liner fitment or crankshaft components.

Crankshaft Seals

Both front and rear crankshaft seals are available in standard, single lip, and double lip designs, as well as oversize versions. These seals are designed for long service life and prevent oil leakage, which is vital for maintaining engine cleanliness and preventing bearing wear.

Fuel System Components

A properly rebuilt 8V71 relies heavily on clean, filtered fuel. Overhaul kits are complemented by fresh filters and supporting components.

Fuel Filters

• Primary Filters: Available in both cartridge and spin-on designs, these protect injectors and pumps from debris.

• Secondary Filters: Ensure ultra-fine filtration to safeguard the fuel injection system.

Filter Removal Tools

Specialized wrenches are designed to safely remove and install filters without causing damage to housings or filter elements.

Oil System Protection

Rebuilt engines require clean lubrication from the start. Diesel Pro Power supplies both cartridge and spin-on oil filters to match your 8V71 configuration.

Benefits of Using OEM-Spec Oil Filters:

• Prevents abrasive particles from circulating through bearings and journals

• Maintains proper oil pressure

• Extends the life of pistons, rings, and liners

Cooling System Components

The Detroit Diesel 8V71 depends on consistent cooling, particularly in marine environments where engines are subjected to continuous duty at varying loads.

Thermostats

Available in 160, 170, and 180-degree ratings to match your application. Thermostats regulate coolant flow, ensuring your engine maintains the ideal operating temperature for performance and efficiency.

Thermostat Seals

A critical sealing element that prevents coolant leaks around thermostat housings.

Radiator Cleaner

Over time, coolant passages accumulate scale and deposits. Radiator cleaners help restore flow and efficiency, protecting against overheating after a rebuild.

Piston and Ring Installation Tools

Rebuilding a Detroit Diesel 8V71 requires precision. Tools such as piston ring compressors and piston ring assembly tools are designed specifically for the 71 Series to make installation easier and safer.

Why These Tools Matter:

• Ensure rings compress evenly without breakage

• Reduce installation time

• Guarantee proper seating of pistons inside liners
