Each component listed below is engineered for precision fitment and durability, helping ensure your engine operates at peak performance and efficiency.

Detroit Diesel Oil Pumps for the 3-53 Engine

The oil pump is the heart of the Detroit Diesel 3-53 lubrication system. Its job is to draw oil from the pan and deliver it under pressure through filters, galleries, and bearings, ensuring that every moving component—from the crankshaft to the camshaft and pistons—remains properly lubricated.

Detroit Diesel Oil Pump for 3-53 Engine (New)
This new oil pump is precision-manufactured to meet or exceed factory specifications. It features the correct pressure balance and gear configuration to maintain consistent oil flow, even in heavy-duty or high-RPM applications. Each pump undergoes detailed inspection for gear clearance, body tolerances, and pressure relief calibration to ensure maximum longevity and reliability.

Detroit Diesel Oil Pump for 3-53 Engine (Rebuilt)
For those seeking cost-effective solutions, Diesel Pro Power also offers professionally rebuilt Detroit Diesel oil pumps. Each rebuilt unit is completely disassembled, cleaned, machined, and reassembled using OEM-standard components. Critical wear parts are replaced, and the final pump is pressure-tested before being made available for sale. These rebuilt pumps deliver factory-level performance and are backed by Diesel Pro’s commitment to quality.

Both options—new and rebuilt—are designed to maintain oil pressure within the optimal range for the Detroit Diesel 3-53, typically between 40 and 60 PSI under normal load conditions.

Oil Pump Drive Gear

The oil pump drive gear transfers rotational power from the engine’s camshaft gear to the pump itself. Diesel Pro Power’s drive gears are manufactured with hardened steel teeth, ensuring consistent performance and minimal wear under the high torque loads typical of the 3-53 and other Series 53 engines.

This gear is interchangeable with the 4-53 and 6V53 versions, but its configuration and fit are verified for proper timing and alignment with the 3-53’s oil pump assembly. Each gear undergoes precision machining and is balanced to prevent vibration or excessive wear on the pump shaft and cam drive.

Oil Pump Relief Spring

The oil pump relief spring plays a crucial role in maintaining steady oil pressure within the lubrication system. It prevents over-pressurization by opening a bypass valve when pressure exceeds the preset limit.

Diesel Pro Power’s replacement relief springs are made from tempered steel, ensuring consistent tension and correct pressure calibration. This component is compatible with multiple Detroit Diesel Series 53 engines, including 3-53, 4-53, 6V53, and 8V53 configurations. Replacing a weak or fatigued relief spring is one of the most effective ways to restore proper oil pressure regulation.

Crankshaft Seals and Seal Sleeves

Oil leaks around the crankshaft are common on older engines, particularly at the front seal where the crankshaft exits the timing cover. Diesel Pro Power offers both standard and oversize front crankshaft seals for the 3-53 engine, ensuring a tight, leak-free fit.

Crankshaft Seal – Standard Front (Single Lip)
Ideal for engines with minimal wear on the crankshaft journal, this seal provides reliable oil retention and resists heat, pressure, and oil contamination.

Crankshaft Seal – Oversize Front (Single Lip)
For engines where the crankshaft journal has minor wear or scoring, the oversize seal provides additional sealing diameter to compensate for imperfections.

Crankshaft Seal Sleeve – Front Oversize
When the crankshaft surface is too worn for a reliable seal, this repair sleeve restores the sealing area by creating a new, hardened surface for the oversize seal to ride on. Together, the sleeve and seal combination extend the crankshaft’s life and prevent front-end oil leaks.

Detroit Diesel Oil Coolers

Oil cooling is critical for maintaining stable operating temperatures and preventing premature wear on bearings and pistons. Diesel Pro Power offers 6-plate and 8-plate oil coolers designed specifically for the Series 53 family.

6-Plate Oil Cooler
Compact and efficient, this cooler suits most light-to-medium-duty applications where space and weight are considerations.

8-Plate Oil Cooler
The 8-plate version provides enhanced cooling capacity for engines operating in high-load, high-temperature environments such as marine propulsion systems, heavy construction machinery, or industrial compressors.

Each oil cooler is thoroughly pressure-tested for leaks and built using corrosion-resistant materials to ensure durability in harsh operating environments.

Oil Cooler Gaskets

Proper sealing between the oil cooler and housing is essential to prevent oil leaks or cross-contamination. Diesel Pro Power supplies high-quality oil cooler gaskets made from durable, heat-resistant materials.

Two gasket versions are available, both compatible with the 3-53’s cooler housing. These gaskets ensure reliable sealing and easy installation during maintenance or rebuild procedures.

Oil Pan Gasket and Lower Cover Gasket

The oil pan gasket prevents leaks between the oil pan and engine block. Diesel Pro Power’s replacement gasket is cut from premium composite material to resist oil, heat, and vibration.

The front lower cover gasket (sometimes referred to as the oil pump cover gasket) seals the joint between the timing cover and oil pump assembly. A fresh gasket helps prevent pressure loss and oil seepage—critical for maintaining the lubrication system’s integrity.

Oil Filter Components

Clean oil is essential for the health of your Detroit Diesel 3-53. Diesel Pro Power carries both spin-on and cartridge-type oil filters, as well as related accessories for servicing and removal.

Spin-On Oil Filter
The spin-on design simplifies maintenance, allowing for quick filter changes without disassembly of the housing. Each filter provides superior filtration, trapping fine contaminants that could damage bearings or clog oil passages.

Cartridge-Type Oil Filter
Used in older or industrial-style 3-53 applications, the cartridge filter offers excellent flow characteristics and fine filtration capabilities.

Oil Filter Adaptor Gasket
Ensures a tight seal between the filter base and housing, preventing leaks during operation.

Oil Filter Removal Wrench
This adjustable tool fits oil filters from 4-21/32” to 5-5/32”, allowing easy removal of spin-on filters without damage.

Oil Fill Cap, Dipsticks, and Tubes

Maintaining correct oil levels is vital for lubrication and cooling. Diesel Pro Power offers OEM-style oil fill caps, dipsticks, and dipstick tubes for accurate oil level monitoring.

Oil Fill Cap or Lid for Head Cover
Seals the oil fill port and prevents contamination or oil splash from the valve cover area.

Dipsticks (61” and 72”)
Available in two lengths to accommodate different installation configurations, including marine and industrial setups. Each dipstick includes engraved markings for precise oil level readings.

Dipstick Tube and Guide
