PAI engine components offer a quality aftermarket solution for professional diesel technicians, heavy-duty repair shops, owner-operators, and commercial truck fleets.

This engine overhaul kit is intended for compatible PACCAR MX-13 12.9L diesel engines commonly found in Kenworth and Peterbilt heavy-duty trucks. Because component specifications can vary by engine generation, production date, and engine serial number, the exact kit configuration must be confirmed before fulfillment.

Important: VIN & Engine Serial Number Verification Required

After your order is placed, our team will contact you by email to confirm your truck's Vehicle Identification Number (VIN) and engine serial number (ESN).

This information allows us to identify the correct PAI inframe overhaul kit for your specific PACCAR MX-13 engine configuration.

• VIN: Required to verify the truck's original vehicle and engine application.
• Engine Serial Number (ESN): Required to identify the engine's specific configuration and applicable rebuild components.
• Kit Verification: Our team will review the supplied information before confirming the appropriate kit configuration.
• Order Processing: Kit fulfillment is subject to successful VIN and engine serial number verification.

Please monitor your email after placing your order. Delays in providing the requested information may delay order processing and shipment.

Additional parts or machining services may be required to complete an engine rebuild.

PACCAR MX-13 Diesel Engine Applications

The PACCAR MX-13 is a 12.9-liter heavy-duty diesel engine used in various Kenworth and Peterbilt commercial truck applications. This inframe overhaul kit listing is intended for compatible MX-13 engine configurations, subject to VIN and engine serial number verification.

Potential applications include compatible Kenworth and Peterbilt trucks equipped with PACCAR MX-13 engines, such as:

• Kenworth T680
• Kenworth T880
• Kenworth W900
• Kenworth W990
• Peterbilt 579
• Peterbilt 567
• Other compatible PACCAR MX-13-powered trucks

Vehicle model alone does not guarantee kit compatibility. Engine serial number verification is required because different MX-13 engines may use different internal components.

When Should You Consider an MX-13 Inframe Overhaul?

An inframe engine overhaul may be considered when inspection and diagnostic testing indicate excessive wear or damage to internal engine components.

Common conditions that may lead to further engine inspection include:

• Excessive engine oil consumption
• Low compression caused by internal engine wear
• Excessive crankcase blow-by
• Worn piston rings or cylinder liners
• Internal bearing wear
• Engine performance concerns related to mechanical wear
• High-mileage engines requiring major internal repairs

Proper diagnosis and dimensional inspection should be performed before selecting replacement parts or beginning an overhaul.
