2009 Husqvarna TE310 Dirt Bike Torque Specs
Shop parts for a 2009 Husqvarna TE310 Dirt Bike.
The 2009 Husqvarna TE310 occupied a unique niche in the enduro lineup—a 310cc four-stroke single designed for a broad, tractable power delivery suited to long-distance off-road riding and enduro competition. The four-stroke architecture of the TE310 means a different maintenance focus than the two-stroke TE models, with oil system fasteners, valve cover hardware, and a more extensive engine fastener set that reflects the added mechanical complexity of the four-stroke platform. This torque reference covers all critical fasteners for the 2009 TE310.
Engine Torque Specifications
The 2009 TE310's four-stroke single has several engine fastener categories that don't apply to the two-stroke TE models. Cylinder head bolts on a four-stroke typically carry higher torque values due to the increased combustion pressure, and the oil drain plug is a service point unique to the four-stroke platform.
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Spark plug | 20–22 | 15–16 |
| Cylinder head bolts | 45–55 | 33–41 |
| Cylinder base bolts | 20–25 | 15–18 |
| Oil drain plug | 20–25 | 15–18 |
| Flywheel/rotor nut | 60–70 | 44–52 |
| Clutch hub nut | 60–70 | 44–52 |
Drivetrain & Wheels
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Front axle nut | 25–30 | 18–22 |
| Rear axle nut | 65–70 | 48–52 |
| Rear sprocket bolts | 35–40 | 26–30 |
| Chain adjuster lock nuts | 20–25 | 15–18 |
Suspension & Chassis
The 2009 TE310's four-stroke mass is slightly higher than the two-stroke TE models, and the chassis is configured accordingly with appropriate spring rates and geometry for enduro use with the heavier engine package. Fork clamp bolt torque keeps this heavier chassis system aligned correctly for consistent steering input.
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Upper fork clamp bolts | 15–18 | 11–13 |
| Lower fork clamp bolts | 18–22 | 13–16 |
| Handlebar clamp bolts | 20–25 | 15–18 |
| Swingarm pivot bolt | 65–75 | 48–55 |
| Rear shock linkage bolts | 45–55 | 33–41 |
Brake System
| Fastener | Torque (Nm) | Torque (ft-lb) |
|---|---|---|
| Front brake caliper bolts | 25–30 | 18–22 |
| Rear brake caliper bolts | 25–30 | 18–22 |
| Brake disc bolts | 16–20 | 12–15 |
Dry vs. Wet Torque
The 2009 TE310 four-stroke introduces oil drain plug service as a regular torque point. The drain plug should be torqued dry with a fresh aluminum crush washer at each oil change—a previously compressed washer loses its sealing ability and must be replaced. The cylinder head bolt torque on this four-stroke is applied dry and typically requires a multi-stage torque sequence: a first pass at approximately half the target value, then a final pass to full torque in a cross or star pattern.
Thread Locker Application
Medium-strength thread locker on brake disc and sprocket bolts is standard for the 2009 TE310. On the four-stroke engine, valve cover bolts are another common loosening point—vibration from the four-stroke firing pattern can back these out gradually, causing oil misting around the valve cover if not addressed.
Torque Wrench Selection
The 2009 TE310 four-stroke requires a click-type wrench with a wider range than the smaller two-stroke models—a 3/8-drive unit (10–100 Nm) covers all primary fasteners including the higher cylinder head bolt torque values. For smaller engine fasteners like valve cover bolts and spark plug, a 1/4-drive wrench (2–25 Nm) provides better precision at the lower end of the torque range.
Failure Consequences
On the 2009 TE310, over-torquing the oil drain plug strips the aluminum sump threads—a repair that requires a thread insert and affects oil change service for the life of the bike. Under-torqued cylinder head bolts on this four-stroke cause head gasket failure that's more dramatic than on a two-stroke—hot coolant or oil can escape alongside compression gasses, creating a combined mechanical and fluid leak that requires immediate repair. Use a calibrated wrench on every drain plug service and every head bolt check.
