2013 Husqvarna TXC310 Dirt Bike Torque Specs
Shop parts for a 2013 Husqvarna TXC310 Dirt Bike.
The 2013 Husqvarna TXC310 was the final year of this displacement configuration in the TXC cross-country lineup. With its 303cc four-stroke engine refined through several seasons of development, the TXC310 represented a mature, capable platform for competitive cross-country and enduro riders. Whether you’re servicing a recently acquired TXC310 or maintaining one that has been in your stable since new, these torque specifications ensure every critical fastener is secured to the standards that protect the bike’s performance and longevity.
Engine and Powertrain Torque Specs
The 2013 TXC310's engine hardware torque values are consistent with the 2012 model. Cylinder head bolt sequences should progress from center outward in a star pattern to distribute clamping force evenly across the gasket. For any engine rebuild on a 2013 model, inspect all threaded holes in the aluminum cases before reassembly—corroded or damaged threads reduce the accuracy and reliability of torqued fasteners and should be repaired before assembly.
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Cylinder head bolts | 25–28 | 18–21 |
| Cylinder base bolts | 20–22 | 15–16 |
| Spark plug | 15–20 | 11–15 |
| Oil drain plug | 20–25 | 15–18 |
| Flywheel/rotor nut | 60–70 | 44–52 |
| Clutch hub nut | 85–95 | 63–70 |
Dry and Wet Torque Considerations
Dry torque governs all engine and chassis fasteners on the 2013 TXC310. This means no oil, grease, anti-seize, or assembly lubricant on threads before torquing—unless specifically required for a sealing function. Thread contamination is one of the most common causes of inaccurate torque application in field service. If old thread locker residue is present, remove it completely with solvent and a wire brush before applying fresh thread locker and torquing to specification.
Drivetrain Hardware
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Front axle nut | 25–30 | 18–22 |
| Rear axle nut | 65–75 | 48–55 |
| Rear sprocket bolts | 35–40 | 26–30 |
| Chain adjuster lock nuts | 15–20 | 11–15 |
Chassis and Suspension Torque Values
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Swingarm pivot bolt | 50–60 | 37–44 |
| Fork clamp bolts (upper) | 15–18 | 11–13 |
| Fork clamp bolts (lower) | 20–22 | 15–16 |
| Handlebar clamp bolts | 20–25 | 15–18 |
| Rear shock linkage bolts | 40–50 | 30–37 |
Brake Hardware
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Brake caliper mounting bolts | 25–30 | 18–22 |
| Brake disc bolts | 10–12 | 7–9 |
| Brake master cylinder bolts | 8–10 | 6–7 |
Thread Locker and Torque Wrench Guidance
For the 2013 TXC310, apply medium-strength thread locker to brake disc bolts, sprocket hardware, and rear linkage bolts at every rebuild. These fasteners benefit most from chemical retention in the cross-country environment. A click-type or digital torque wrench handles the full range of TXC310 service fasteners accurately. Inspect all hardware at the end of each race season, replacing any fasteners showing signs of fatigue, corrosion, or thread damage. This is a final-year model—replacement parts may require sourcing from specialty suppliers, making preventative fastener maintenance more important than on newer platforms.
