Oil Pump Relief Spring – Pressure Regulation and Protection

The Oil Pump Relief Spring acts as the safety valve of the lubrication system. It maintains consistent oil pressure by diverting excess flow back into the sump when pressure exceeds factory settings. This protects seals, gaskets, and bearings from damage due to over-pressurization.

Diesel Pro Power’s relief spring is built to Detroit Diesel’s specifications, ensuring precise tension and reliable response under varying oil viscosities. It’s a simple but critical part that guarantees your lubrication system performs optimally whether the engine runs cold or at full operating temperature.

Crankshaft Seals and Sleeves – Preventing Oil Leaks and Pressure Loss

Maintaining oil containment in a turbocharged two-stroke engine is critical. Diesel Pro Power offers a complete range of crankshaft seals for the Detroit Diesel 3-53 Turbo, including both standard single-lip seals and oversized versions for worn housings. Each seal is molded from premium heat-resistant elastomer designed to withstand extended exposure to high temperatures and crankcase pressure.

Front Crankshaft Seal – Standard
Designed for standard crankshaft diameters, this seal provides a tight barrier between the crankcase and the exterior environment, keeping oil inside and contaminants out.

Front Crankshaft Seal – Oversize
The oversize version is ideal when the crankshaft or housing surface has been lightly machined or shows minor wear. It restores sealing integrity and prevents oil seepage during high-load operation.

Crankshaft Seal Sleeve – Oversize Application
