Why Diesel Pro Power Charges a Core Charge for Rebuilt Blowers

A Simple, Proven System That Keeps Blowers In Stock When You Need Them

When you buy a rebuilt blower for a Detroit Diesel two-stroke engine—such as the 6-71, 8V71, 12V71, 8V92, or 149 Series—you’ll see a core charge included in the order. Many customers wonder why this charge exists and what it means for them.

At Diesel Pro Power, the core charge is essential for one important reason:

It ensures we always have rebuilt blowers in stock, ready to ship the same day you order.

Here’s exactly how it works and why it benefits every Detroit Diesel owner.

What Is a Core Charge?

A core charge is a refundable deposit added when you purchase a rebuilt blower. When you send back your old blower core, the deposit is refunded—as long as the core is rebuildable and the proper return process is followed.

It isn’t an extra fee.
It isn’t a penalty.
It’s simply a temporary deposit that comes back to you once the core is returned correctly.

Why Diesel Pro Power Uses a Core Charge

1. It Keeps Blowers In Stock for Customers

Detroit Diesel does not manufacture new two-stroke blowers anymore. The only way to maintain inventory is through customer core returns.

Each returned core becomes the base for the next rebuilt blower we make available.

When customers return their rebuildable units, it allows us to keep:

• A deep inventory
• Consistent availability
• Same-day shipping
• No backorders

This is the system that prevents delays and keeps your equipment or vessel running.

2. It Prevents Inventory Shortages

Without core returns, rebuilt blowers would rapidly disappear from the market. By returning your core:

• You help avoid supply gaps
• You keep older engines supported
• You help ensure future availability for yourself and other operators

This is especially important for working vessels, commercial operations, industrial equipment, and generators where downtime equals lost revenue.

3. It Helps Keep Pricing Stable

If Diesel Pro Power had to source blower cores from independent sellers, the cost would increase dramatically.

Consistent core returns allow us to:

• Keep pricing fair
• Avoid shortages
• Reduce overall rebuild expenses
• Maintain a dependable supply chain

Everyone benefits from a healthy, steady flow of rebuildable cores.

4. Better Cores = Better Rebuilt Blowers

Returning your used blower ensures we have:

• Good-quality housings
• Rebuildable rotors
• Salvageable internal components

This helps us maintain the high-quality standards our customers expect.

Better incoming cores mean better rebuilt blowers going back out.

How the Refund Process Works (Important)

To receive your core refund, two conditions must be met:

1. The blower core must be rebuildable

The returned blower must be:

• Structurally sound
• Free of major cracks or housing damage
• Internally intact enough to be rebuilt

If the blower is destroyed, missing major components, or not rebuildable, it cannot be accepted for refund.

2. You must complete a Return of Goods Authorization (RGA) form

Before returning your core, you must fill out a simple Return of Goods Authorization form. This ensures:

• Your core return is properly documented
• It is matched to your order
• The refund is processed correctly and promptly

Once the rebuildable core arrives and the RGA is verified, the core charge is refunded in full.

The process is straightforward and designed to make the return as easy as possible.

What This Means for You

The core charge exists for one purpose:

To make sure Diesel Pro Power can always provide rebuilt blowers quickly, reliably, and at a fair price.

Because of this system, customers benefit from:

• Same-day shipping
• Large inventory in stock
• Reliable rebuilt quality
• Fair and stable pricing
• Parts support for both common and rare Detroit Diesel engines

Whether your Detroit Diesel powers a commercial vessel, tugboat, generator, or industrial machine, this system keeps you running.

Bottom Line

A core charge supports the entire rebuilt blower supply chain. It ensures:

• You get your blower fast
• Inventory remains available
• Prices stay stable
• Engines stay supported for years to come

And when your rebuildable core is returned with a completed RGA form, your deposit comes right back to you.
