Frequently Asked Questions About International 8600 TranStar Drivetrain Parts

Will these drivetrain parts fit my specific year International 8600 TranStar?

Most of our drivetrain components are compatible with International 8600 TranStar models from 2007 to 2017. However, there are variations between model years, particularly in transmission types and differential ratios. We recommend checking your VIN or calling our parts specialists at 1-888-875-7787 with your truck's serial number to ensure exact fitment. Key differences often occur in 2010+ models due to emission control updates that affected drivetrain configurations.

What are the most common drivetrain failure points on the 8600 TranStar, and which parts should I keep in stock?

Based on customer feedback and service records, the most frequent replacement items are U-joints (especially on trucks with over 500,000 miles), carrier bearings, and transmission synchronizers. For preventive maintenance, we recommend keeping universal joint kits, transmission filters, and differential fluid on hand. Heavy-haul operators often experience accelerated wear on clutch components and should consider our heavy-duty clutch kits rated for 1,850 lb-ft of torque.

Can I install these drivetrain parts myself, or do I need special tools?

While experienced mechanics can handle many drivetrain repairs, certain components require specialized equipment. U-joint replacements typically need a hydraulic press or heavy-duty C-clamp. Transmission work requires proper lifting equipment and torque specifications. Differential repairs often need bearing pullers and precise shimming tools. We provide detailed installation guides with each part, but recommend professional installation for transmission internals and differential rebuilds to maintain warranty coverage.

What's the difference between OEM and aftermarket drivetrain parts for my TranStar?

OEM parts are manufactured to International's exact specifications and typically carry a 12-month warranty. Our aftermarket options from brands like Eaton, Meritor, and Spicer often meet or exceed OEM standards at 20-40% lower cost. For example, our Spicer Life Series U-joints feature superior needle bearing design compared to standard OEM joints. Critical components like transmission gears and differential cases should match OEM specs exactly, while wear items like filters and seals offer more flexibility in brand choice.

How can I identify which transmission or differential I have in my 8600 TranStar?

Look for the identification tag on the transmission housing (usually driver's side) or differential housing (front face). Common transmissions include Eaton Fuller 10-speed (FRO-14210B, FRO-15210B) and 13-speed (RTLO-16913A) models. Differentials are typically Meritor RT-40-145 or RT-46-160 series. The tag will show model number, serial number, and ratio. If tags are missing or illegible, count the forward gears, note whether you have single or tandem axles, and check the driver's door jamb sticker for original equipment specs.
