Changing the gearbox oil in your 2014 Husqvarna TE300 is a critical part of routine maintenance, helping to ensure smooth shifting and a long life for your clutch and transmission components. For MotoSport.com readers, here’s a robust, step-by-step guide that will walk you through the process, highlight the tools you’ll need, outline Husqvarna TE300-specific call-outs, and provide expert tips to get the job done right the first time.

Tools and Supplies Needed

  • 8mm socket with a 1/4 inch drive (for certain side covers, check your specific bike)
  • 13mm socket with a 1/2 inch drive (for the drain bolt)
  • Torque wrench (capable of low settings, as you’ll need it for plug bolts)
  • Oil drain pan (large enough to catch all draining oil)
  • Measuring jug or graduated beaker (to pour the correct oil amount)
  • Funnel (optional but recommended for tidy pouring)
  • Rag or paper towels (for cleaning up spills and wiping down bolts)
  • Replacement gearbox oil: Husqvarna recommends a 15W50 full synthetic gearbox oil for the TE300, meeting or exceeding the manufacturer’s specifications

Model-Specific Callouts for the 2014 Husqvarna TE300

  • This bike is a two-stroke, so you are only changing the gearbox oil, not engine oil—the crank assembly is lubricated via the fuel/oil mixture.
  • Capacity is roughly 800 mL (or about 0.85 US quarts), but always fill to the level check hole for proper height (see below for details).
  • The oil drain bolt torque spec is generally found at 11 ft-lbs (about 15 Nm) for gearbox sump and 7 ft-lbs (about 9.5 Nm) for the level check plug. Always verify in your exact owner’s manual if available, but these figures are widely used for this model year.
  • This model does not use a replaceable oil filter for gearbox oil changes—just drain and refill.

Step-by-Step Guide to Changing the Oil

  1. Warm up the engine.
    • Run the bike for a few minutes to get the gearbox oil warm. Warm oil drains easier and carries away more contaminants.
  2. Place the motorcycle securely on a stand.
    • Keep the bike as level as you can; many owners use a center stand for best results.
  3. Remove the drain plug.
    • Position your drain pan underneath the engine.
    • Use your 13mm socket to remove the gearbox oil drain bolt underneath the engine. Let the oil drain fully—this may take several minutes, especially if the oil is cold.
    • Tip the bike slightly (tilt around 30 degrees towards you) to make sure all pooled oil is released, as oil tends to stay trapped in engine nooks if not tipped gently.
  4. Inspect and clean the drain plug.
    • Most drain bolts have a magnetic tip to catch metal shavings; wipe this off carefully with a rag.
    • Check for excessive metal debris; some “fuzz” is normal, but large or sharp chunks may indicate a problem.
  5. Reinstall the drain plug.
    • Once the oil is fully drained, clean the bolt threads, and reinstall it using your torque wrench set to 11 ft-lbs (or recommended factory spec).
  6. Remove the oil fill and level check plugs.
    • On the right side of the engine case, remove the fill plug (usually with an 8mm socket or Allen key).
    • Immediately below the fill plug (or slightly forward, depending on exact model), remove the oil level check bolt—some people call this the “level screw.”
  7. Add new oil.
    • Use a funnel to slowly pour in 15W50 full synthetic gearbox oil. Pour slowly to avoid overflow.
    • Watch the level check hole: when fresh oil just begins to run out of this hole, you’ve filled enough. For the TE300, this usually takes just under 800 mL, but always rely on the visual check hole rather than a strict measurement.
    • Let any excess drain out, then reinstall the level check bolt (torque to 7 ft-lbs or as per your manual).
    • Install the fill plug and snug to spec.
  8. Final checks and cleanup.
    • Wipe down any oil spills or drips. Double-check all plugs are tight, but do not overtighten, as the cases are aluminum and threads can strip easily.
    • Check around the plug area for leaks after your first post-change ride.

Pro Tips for the 2014 Husqvarna TE300

  • If you routinely ride in harsh conditions (deep water, mud), shorten your oil change intervals.
  • Always use quality full synthetic oil recommended by the manufacturer to maximize gearbox life.
  • Changing gearbox oil every 6–10 hours of riding is common for off-road/enduro use, but adjust as dictated by riding style and conditions.
  • If you notice milky oil (indicating water contamination) or significant metal in the old oil, investigate for mechanical issues before next ride.

With the right tools and a little care, changing the gearbox oil on your 2014 Husqvarna TE300 is quick, clean, and will help keep your two-stroke performing at its best. Ride safe, and remember: MotoSport.com has all the supplies and genuine parts you need for the job.
