Description
Product Overview
The Milodon oil pump shaft is engineered from CNC‑machined 4130 chrome‑moly billet, a material renowned for its superior strength‑to‑weight ratio and resistance to fatigue. Each shaft undergoes centerless grinding to remove stress concentrations, followed by a precise heat‑treatment of the ends to minimize wear during prolonged high‑rpm operation. Measuring 9.8 x 5.9 x 0.6 inches and weighing only 3.2 ounces, the shaft offers a compact yet robust solution for demanding automotive performance applications.
Usage
Designed for high‑performance engines, this shaft excels in environments where oil pumps operate at elevated volumes and speeds. It is perfect for race‑car builds, track day vehicles, and any high‑output street car that relies on consistent lubrication. Install the shaft in any compatible Milodon oil pump to achieve smoother oil delivery, reduced pump cavitation, and enhanced engine longevity.

FAQ
What engines are compatible with this shaft?
The shaft fits any Milodon oil pump model that uses the standard 22565 part number, typically found in high‑performance V8, V6 and inline‑four applications.
How does centerless grinding improve reliability?
Centerless grinding creates a uniform surface without the concentric stress points that can develop during traditional grinding, reducing the likelihood of cracks under high stress.
Do I need to heat‑treat the shaft after installation?
No additional heat treatment is required. The ends are pre‑treated at the factory to provide wear resistance right out of the box.
Can this shaft be used with aftermarket oil pumps?
Yes, as long as the pump’s mounting dimensions match the 22565 specification, the shaft will function correctly with most aftermarket high‑flow pumps.
What maintenance is recommended?
Regular oil changes and periodic inspection of the shaft for wear are advised. Replace the shaft if you notice scoring or excessive play.
