Detroit Diesel Oil Pump Drive Gear – 35-Tooth Precision

The oil pump’s performance depends heavily on its drive gear. The Detroit Diesel Oil Pump Drive Gear for the 353, 453, and 6V53 engines features precision-cut 35-tooth steel construction for consistent torque transfer from the crankshaft. This gear ensures the pump maintains steady oil pressure and reduces the risk of slippage or wear.

Machined to exact Detroit Diesel tolerances, this gear resists heat distortion and long-term fatigue. For rebuilders and maintenance technicians, replacing the drive gear during a pump overhaul is always recommended to prevent premature failure of new pumps.

Oil Pump Relief Spring – Maintaining Proper Pressure

Oil pressure control is managed by the Detroit Diesel Oil Pump Relief Spring, which functions as the pressure regulator inside the oil pump assembly. The spring opens when oil pressure exceeds factory specifications, allowing excess oil to bypass and return to the sump, thereby protecting seals, bearings, and gaskets from over-pressurization.

Compatible with Series 53 engines—including the 353, 453, 6V53, and 8V53—this spring is a small but critical component. Over time, relief springs can weaken, leading to fluctuating or low oil pressure readings. Replacing it with a new spring restores stable pressure and ensures optimal lubrication system balance.

Crankshaft Seals and Sleeves – Preventing Oil Leaks

Detroit Diesel Crankshaft Seals (standard and oversize) protect the engine from oil leakage around the crankshaft front housing. Available in single-lip configurations, they’re engineered from high-temperature rubber compounds that resist hardening and oil breakdown.

For engines with minor wear on the crankshaft sealing surface, an oversize seal paired with a front seal sleeve restores proper sealing without requiring crankshaft replacement. This combination prevents oil seepage, keeps the front housing clean, and maintains internal oil pressure efficiency.

Diesel Pro Power offers both standard and oversize options, each designed for the 3-53, 4-53, and 6V53 engine families.

Detroit Diesel Oil Coolers – 8-Plate and 13-Plate Designs

The oil cooler is the heart of the engine’s temperature regulation system. The Detroit Diesel 8-Plate Oil Cooler provides efficient heat transfer for lighter-duty or single-engine configurations, while the 13-Plate Oil Cooler handles higher heat loads, ideal for continuous heavy operation.

Both coolers feature brazed-plate aluminum cores that maximize surface area for heat dissipation. The 13-Plate Oil Cooler with Nipples option simplifies installation by integrating fittings directly into the cooler housing.

These units are designed to maintain consistent oil temperatures, preventing viscosity breakdown and ensuring reliable lubrication during high-load conditions.

Oil Cooler Gaskets – Reliable Sealing Under Pressure

To complete an oil cooler installation, Diesel Pro Power provides Detroit Diesel Oil Cooler Gaskets that guarantee a leak-free seal between the cooler and housing. Available in multiple material options to handle both 8- and 13-plate configurations, these gaskets are oil-resistant and dimensionally stable even under prolonged exposure to heat and pressure.

Replacing gaskets during any oil cooler service is critical—reusing old gaskets often leads to leaks and oil contamination.

Detroit Diesel Oil Pan Gaskets – For Steel and Cast Iron Pans

The Detroit Diesel Oil Pan Gasket for the 4-53 engine forms a secure seal between the engine block and oil pan. Diesel Pro Power offers two configurations: one for standard pans and one specifically for cast-iron oil pans.

These gaskets are manufactured from reinforced fiber materials to prevent leaks and resist oil saturation. Regular inspection and replacement during oil pump or pan service help preserve crankcase pressure and keep oil levels stable.

Gasket for Front Lower Cover – Protecting the Oil Pump Cavity

Located near the base of the timing gear housing, the Front Lower Cover Gasket seals the oil pump cavity and prevents oil seepage around the pump drive assembly. A compromised gasket here can cause external leaks and pressure drops within the lubrication system.

Diesel Pro Power supplies OEM-grade gaskets for precise fit and reliable service.

Detroit Diesel Oil Filter System Components

Oil Filter Base (Cartridge Type):
This heavy-duty base is the foundation for cartridge-style oil filters. It secures the filter and directs oil through the filtration element for thorough cleaning before re-circulation.

Oil Filter Adaptor (Cartridge to Spin-On):
For owners updating older engines, Diesel Pro Power provides a conversion adaptor that allows a modern spin-on oil filter to replace the original cartridge type. Spin-on filters are easier to replace, minimize mess during service, and provide equivalent filtration efficiency.

Gasket for Oil Filter Adaptor:
Each conversion should include a fresh gasket to maintain tight sealing between the adaptor and base, preventing oil seepage under pressure.

Oil Filters – Cartridge and Spin-On:
Diesel Pro Power stocks both filter types, giving customers flexibility depending on their engine setup. Each filter is rated for Detroit Diesel oil system specifications, ensuring debris and contaminants are effectively captured without restricting oil flow.

Oil Filter Removal Wrench:
To make maintenance easier, the Oil Filter Removal Wrench fits spin-on filters between 4-21/32" and 5-5/32" diameter. This tool provides the necessary leverage to remove filters without damaging the housing.
