Detroit Diesel 12V92 Oil Pump – Rebuilt

At the heart of the lubrication system is the Detroit Diesel 12V92 oil pump, responsible for maintaining consistent oil pressure and flow throughout the engine. The pump circulates oil from the sump to the bearings, camshafts, rocker arms, and turbocharger (in turbocharged models), ensuring each moving component remains properly lubricated and cooled.

Diesel Pro Power supplies rebuilt oil pumps for the Detroit Diesel 12V92 Non-Turbo that are completely disassembled, inspected, and reconditioned using high-grade components. Critical clearances are verified to factory specifications, and all pressure-relief mechanisms are calibrated to OEM settings. Each unit is sold with a refundable core deposit, reflecting Diesel Pro’s commitment to sustainability and remanufacturing excellence.

Key features include:

• Precision-ground rotors and housing for optimal oil pressure.

• Factory-tested flow capacity for the 12-cylinder 92-series configuration.

• Compatibility with both marine and stationary versions of the 12V92.

• Reinforced gear drive for stable performance at all RPM ranges.

A rebuilt Detroit Diesel oil pump not only restores proper lubrication but also extends the lifespan of engine bearings and crankshaft journals—critical for engines operating in demanding marine conditions.

Scavenging-Type Oil Pump for Detroit Diesel 12V92

The scavenging-type oil pump used on the 12V92 ensures rapid removal of oil from the crankcase and sump, preventing excessive foaming or oil starvation under heavy loads. Diesel Pro Power’s rebuilt scavenging pumps are engineered to perform with the same reliability as original Detroit Diesel designs, supporting both 12V92 and 16V92 configurations.

Benefits of using a scavenging-type pump:

• Reduces internal friction by maintaining optimal oil levels.

• Improves overall oil circulation efficiency in multi-bank V-12 engines.

• Helps control oil temperature when paired with a properly functioning oil cooler.

Every scavenging-type pump from Diesel Pro is pressure-tested and inspected before shipping, ensuring customers receive components ready for immediate installation.

Gaskets, Shims, and Seals – Ensuring a Leak-Free System

A reliable oil system depends on quality gaskets and seals that can withstand pressure, heat, and vibration. Diesel Pro Power provides OEM-grade oil pump gaskets, inlet gaskets, oil pan gaskets, and shims for proper fitment on the Detroit Diesel 12V92 Non-Turbo engine.

Oil Pump Gasket & Inlet Gasket

The oil pump gasket forms the primary seal between the pump housing and engine block, while the inlet gasket ensures a tight connection between the pump and oil pickup tube. These precision-cut gaskets prevent air leaks that could compromise oil pressure, maintaining consistent flow to critical components.

Oil Pan Gaskets

The 12V92 uses a cast-iron oil pan secured to the block with durable gaskets that prevent leaks under high oil pressures. Diesel Pro offers both standard and small oil pan gaskets designed to match Detroit Diesel specifications.

Oil Pump Shim – 0.05

Shims allow technicians to fine-tune the pump’s installation height and ensure proper gear mesh with the camshaft or crankshaft drive. Using the correct shim thickness prevents wear on drive gears and maintains ideal oil pressure balance.

Oil Pressure Relief and Regulator Valves

The oil system in the 12V92 relies on pressure relief and regulator valves to manage oil pressure throughout the engine. Diesel Pro Power offers high-quality replacement valves that maintain steady pressure during varying engine loads.

• Oil Relief Valve: Prevents excessive pressure buildup by diverting oil back to the sump when system pressure exceeds factory limits.

• Oil Regulator Valve: Ensures balanced pressure delivery to the main oil gallery, protecting bearings from starvation or over-lubrication.

Each valve is machined for precise operation and built to resist corrosion, ensuring long-term reliability even in harsh marine environments.

Oil Filter Base and Adaptors

The oil filter base serves as the connection point between the lubrication circuit and the oil filtration element. Diesel Pro Power provides new and rebuilt cartridge-type oil filter bases, as well as adaptors that allow users to convert from older cartridge systems to modern spin-on filters.

Conversion benefits:

• Simplifies maintenance by allowing tool-free spin-on replacement.

• Improves filter sealing and reduces the risk of leaks.

• Widens availability of compatible oil filters for the 12V92 engine.

Both the filter bases and adaptors are manufactured using corrosion-resistant materials and are compatible with the 12V92’s oil galleries and filter mounts.

Oil Filters – Cartridge and Spin-On Types

Proper filtration is essential to prevent abrasive particles from damaging engine components. Diesel Pro Power offers both cartridge-type and spin-on oil filters suitable for Detroit Diesel 12V92 applications.

Cartridge-Type Oil Filters

These filters are designed for engines with older base assemblies. They use replaceable filter elements housed within a reusable metal canister, offering cost efficiency and long-term reliability.

Spin-On Oil Filters

Spin-on filters are modern, user-friendly alternatives that provide easy installation and superior sealing. The PF911 spin-on oil filter fits Detroit Diesel and Cummins applications, delivering high flow and effective contaminant capture.

To facilitate maintenance, Diesel Pro also supplies oil filter removal wrenches suitable for filter diameters between 4-21/32” and 5-5/32”.

Oil Coolers and Heat Exchangers

The oil cooler is crucial for maintaining proper oil temperature, preventing breakdown of lubricating film under load. Diesel Pro Power carries multiple oil cooler configurations for the Detroit Diesel 12V92, including 24-plate, 32-plate, and double-cooler setups.

Available variations include:

• 24-plate oil cooler (standard)

• 24-plate cooler with nipples (for enhanced circulation)

• 32-plate heavy-duty oil cooler (for continuous marine service)

All coolers are pressure-tested and designed to maintain thermal stability during extended operation. The company also provides a complete installation kit for double oil coolers, ideal for vessels that operate under high thermal load or in tropical waters.

Oil Cooler Gaskets, Seals, and Cover Kits

Every oil cooler requires precise sealing to prevent oil and coolant cross-contamination. Diesel Pro Power supplies a full set of gaskets, cover gaskets, and housing seals designed specifically for Detroit Diesel 12V92 Non-Turbo engines.

Key gasket variants include:

• Oil cooler housing gasket

• Oil cooler cover gasket

• Water inlet gasket and seal

• Oil cooler water manifold seal (2 ½” to 2 ¾” diameters)

Each gasket is manufactured using high-temperature resistant materials to ensure durability in demanding marine applications.

Oil Dipsticks, Tubes, and Guides

Accurate oil level measurement is vital to maintaining lubrication balance in a V-12 engine. Diesel Pro offers dipsticks in multiple lengths—44.25” and 27.25”—to accommodate different 12V92 configurations and mounting orientations. Complementary dipstick tubes and guides are also available, providing a secure passage from the oil pan to the measurement point on the engine.

These components are built from corrosion-resistant materials, designed to withstand vibration and exposure to hot oil vapor.

Oil Pressure Switches and Gauges

To monitor engine health, Diesel Pro Power offers fuel and oil pressure switches in various PSI ratings—5, 10, 20, and 27 PSI—each featuring make/break electrical connections compatible with Detroit Diesel 12V92 systems. The switches help trigger alarms or shutdowns if pressure falls below safe operating thresholds.

Complementing these switches are Diesel Pro’s mechanical and electrical oil pressure gauges available in 12-volt and 24-volt configurations. These instruments allow continuous monitoring of oil pressure, ensuring early detection of lubrication issues before they cause engine damage.
