The 2020 International MV is a medium-duty workhorse relied upon for everything from delivery routes to municipal services. Keeping this truck on the road safely means adhering strictly to the manufacturer’s torque specifications during maintenance and repairs. Whether your MV is equipped with the popular Cummins B6.7 or L9 engine, or an Allison automatic transmission, guessing on torque values is not an option when you are dealing with commercial vehicle gross vehicle weight ratings.
As an ASE-certified master technician, I’ve put together this reference guide to help you find the most common torque specifications for the 2020 International MV.
Quick reference
Below is a quick reference table for common fasteners on the 2020 International MV. Keep in mind that torque values can vary based on the specific engine (Cummins B6.7 / L9), transmission (Allison 2000/3000 series), and brake systems (hydraulic vs. air disc).
| Fastener | Torque (ft-lb / Nm) | Notes |
|---|---|---|
| Wheel lug nuts | 450 - 500 ft-lb (610 - 678 Nm) | Hub-piloted 22mm studs. Apply 2 drops of oil to threads/flange. |
| Oil drain plug | 35 - 44 ft-lb (47 - 60 Nm) | Applies to Cummins B6.7/L9. Always use a new sealing washer. |
| Transmission drain plug | 18 - 25 ft-lb (24 - 34 Nm) | Allison 2000/3000 series. |
| Brake caliper bracket bolts | 180 - 220 ft-lb (244 - 298 Nm) | Check manual; varies by air disc (Bendix) or hydraulic system. |
| Brake caliper slide pins | 40 - 50 ft-lb (54 - 68 Nm) | Typical for hydraulic; Air disc guide pins often require specific multi-step torques. |
| Axle nut (Steer Axle) | Procedure-based | Typically: Torque to 200 ft-lb while spinning, back off 1 full turn, torque to 50 ft-lb, back off 1/6 turn. Check end-play. |
| Glow plugs / Grid heater | 10 - 15 ft-lb (13 - 20 Nm) | Cummins uses an intake grid heater rather than traditional glow plugs; torque applies to terminal nuts. |
| Valve cover bolts | 7 - 9 ft-lb (10 - 12 Nm) | Snug in a cross-pattern from the center outward. |
| Intake manifold fasteners | 18 - 20 ft-lb (24 - 27 Nm) | Follow outward spiral sequence to ensure uniform gasket compression. |
Wheel lug torque pattern
Medium-duty trucks like the International MV typically utilize a 10-lug hub-piloted wheel system. It is absolutely critical to follow a star (or cross) pattern when tightening these heavy-duty lug nuts.
- Start with the top lug nut (12 o'clock).
- Move to the bottom lug (6 o'clock).
- Move to the upper right (2 o'clock).
- Move to the lower left (8 o'clock), and continue crisscrossing across the center of the hub.
Tech Tip: Hub-piloted wheels require two drops of 30-weight oil on the stud threads and between the nut and the integrated washer before installation. Never lubricate the face of the wheel or the brake drum. Always re-torque wheel lug nuts after 50 to 100 miles of driving following wheel removal.
Brake torque notes
The 2020 International MV can be spec'd with either heavy-duty hydraulic brakes or air disc brakes (such as the Bendix ADB22X system). The clamping forces required for brake caliper brackets on commercial vehicles are immense. When dealing with air disc brakes, the caliper slide pins (guide pins) often feature a short pin and a long pin with distinct torque values and complex shear-adapter tightening procedures. Always replace the shear caps on air disc calipers and ensure you are referencing the exact brake manufacturer's procedure.
Why torque matters
In commercial vehicles, torque is directly responsible for bolt stretch, which creates the clamping force holding the vehicle together. Under-torquing a 10-lug wheel can lead to stud fatigue, wheel-off conditions, and catastrophic accidents. Over-torquing stretches fasteners past their yield point, permanently weakening them and risking sudden failure under heavy loads. Relying on an impact wrench without using a calibrated heavy-duty torque wrench is a liability you cannot afford.
Disclaimer: The specifications provided in this article are typical ranges for the 2020 International MV equipped with standard Cummins and Allison drivetrain configurations. Due to the high level of customization in medium-duty trucks, it is imperative that all critical fastener torques be verified against the official OEM service manual for your specific VIN before completing repairs.
