Why Diesel Pro Power Charges a Core Charge for Rebuilt Blowers
A Fair, Industry-Standard Practice That Protects Quality and Keeps Blowers in Stock
When customers purchase a rebuilt Detroit Diesel blower from Diesel Pro Power, they’ll notice a core charge included in the order. The video you have of blower cores stacked and ready for rebuilding is a perfect illustration of why this charge exists and how it ultimately benefits the customer.
Here’s a simple, transparent explanation.
What Is a Core Charge?
A core charge is a refundable deposit added when you buy a rebuilt blower. You get this deposit back as soon as you return your old blower core.
It’s not a fee.
It’s not extra profit.
It’s simply a temporary charge that ensures we can continue rebuilding and keeping these essential components available.

Why a Core Charge Is Necessary
1. Blowers Must Be Rebuildable
Detroit Diesel blowers are no longer made new, so the only way to keep them in circulation is to rebuild used units. When customers return their old cores, we can clean, restore, and completely rebuild them to a like-new condition.
The video of our blower cores shows exactly what we rely on: used housings, rotors, gears, and end plates that can be restored through professional rebuilding.
Without cores coming back, rebuilt blowers simply would not exist.
2. Returning the Core Keeps Prices Reasonable
If cores stopped coming in, the cost of acquiring rebuildable units on the open market would skyrocket. Many would become unavailable altogether.
The core charge ensures:
- We always have rebuildable units in stock
- Prices stay fair for everyone
- Supply remains steady instead of drying up
It protects the customer as much as it protects the inventory.
3. It Encourages Sustainability and Reduces Waste
Rebuilding Detroit Diesel blowers is a form of heavy-duty recycling. Instead of scrapping castings, rotors, and gear housings, we restore them to a second life.
Returning your blower core helps:
- Reduce unnecessary manufacturing waste
- Keep classic engines running
- Support environmentally responsible repair practices
It’s better for the customer, the industry, and the environment.
4. The Refund Is Simple and Fast
Once your old blower core arrives at Diesel Pro Power and is inspected, the core charge is refunded quickly. The process is straightforward, with no hidden deductions or surprise fees.
We don’t believe in making core returns complicated—we just want the rebuildable unit back so it can help the next Detroit Diesel owner.
The Core Charge Helps Maintain a Worldwide Supply
Diesel Pro Power ships rebuilt blowers to 180 countries, supporting commercial fleets, workboats, industrial operations, and engine rebuilders around the world. Keeping this global inventory moving requires a steady flow of good cores.
The blower core video shows the foundation of that system: racks of used blowers ready for the rebuilding process. Every core returned keeps that inventory circulating and ensures we can continue supporting Detroit Diesel operators for years to come.
In Short:
You get your core deposit back.
You help keep prices low.
You help keep Detroit Diesel blowers available worldwide.
And you support a rebuilding process that keeps these legendary engines alive.
