Oil Pump Primer Shaft Milodon CNC Billet 4130

Description

Product Overview

The Milodon oil pump primer shaft is engineered for performance and durability. Constructed from CNC‑machined 4130 chrome‑moly billet, the shaft offers superior tensile strength and resistance to fatigue. Centerless grinding removes stress risers, providing a smooth, uniform surface that enhances oil flow. Heat‑treated ends further reduce wear, extending service intervals for high‑volume oil pumps operating at elevated RPMs.

Usage

Designed for high‑performance automotive engines, this primer shaft excels in racing, track days, and demanding street applications. It is ideal for engines equipped with high‑capacity oil pumps where consistent lubrication is critical. Suitable for professional mechanics, racing teams, and enthusiasts seeking reliable oil delivery under extreme conditions.

FAQ

What engines are compatible with this primer shaft?

The shaft fits most high‑performance automotive engines that use a standard oil pump primer shaft size. Verify your pump model and dimensions before purchase.

How does centerless grinding improve performance?

Centerless grinding creates a uniform surface without stress risers, resulting in smoother oil flow and reduced risk of shaft failure under high loads.

Is heat treatment necessary for oil pump shafts?

Heat treatment hardens the shaft ends, significantly reducing wear from constant friction, which extends the service interval and improves reliability.

Can this shaft be used in street‑driven vehicles?

Yes, it is suitable for both racing and daily‑drive applications where enhanced oil delivery and durability are desired.

What is the warranty on this product?

Milodon offers a limited one‑year warranty covering manufacturing defects for peace of mind.
