Yamaha Rhino 450 Engine – Core Build Remanufacturing Service

If your Yamaha Rhino 450 engine has lost compression, developed internal noise, or started burning oil, we rebuild your engine to restore dependable performance. This is a core build engine, which means we require your rebuildable core before shipment.

However, you may choose to have us build an engine without sending your core first. In that case, we require a refundable core charge and a 50% down payment before work begins.

Core & Payment Options

• Send your rebuildable core first to waive the core charge
• Or pay a refundable core charge plus 50% down payment
• Work does not begin until deposit and core charge are received
• Engines are scheduled in the order cores are received

We recommend calling for current lead times before shipping your engine to ensure a satisfactory turnaround time.

Warranty Coverage

Every rebuilt Rhino 450 engine includes a standard 1-year warranty guaranteeing our work. In addition, you may upgrade to a 2-year no-fault warranty for added protection.

Documentation & Quality Control

This process provides transparency and protects both you and our team.
