This comprehensive MotoSport.com how-to guide will walk you through every step, highlight the specific tools and materials required, and note any special callouts or tips for this model.

Tools and Materials Needed

  • 8mm T-handle or socket/ratchet (for drain and fill bolts)
  • Drain pan or bucket (for old oil)
  • Oil funnel (optional but helpful for mess-free filling)
  • Crush washer (replace if damaged or after several changes)
  • Shop towels or rags
  • Gear oil, 500cc (0.5L) (Motul Trans Oil or equivalent 75W/80W, per manual and dealer recommendations)
  • Torque wrench (for precise tightening, set to 15 Nm/11 ft lbs for drain bolt)
  • Safety gloves and appropriate eye protection

Preparation Steps

  • Warm up the engine for a couple of minutes. This helps the oil flow out more easily and carries any contaminants with it.
  • Place the bike on a stand or level surface. This ensures even draining and accurate oil level filling.
  • Make sure the area is well-ventilated and free of ignition sources.

Step-by-Step Guide

  1. Remove the Drain Plug
    • Locate the gear oil drain bolt on the bottom of the transmission case (left side, under the engine).
    • Place your drain pan directly beneath the bolt.
    • Using your 8mm T-handle or socket, carefully loosen and remove the drain plug. Allow the old oil to flow completely into the pan.
    • Check the crush washer on the drain plug. Replace if deformed or after every few changes for best sealing.
  2. Remove the Filler Cap
    • The filler cap is typically on the right side of the engine. Remove it with your fingers or a soft tool if it's tight.
    • This will help the oil drain faster.
  3. Wait for Complete Drainage
    • Give the oil several minutes to fully drain out.
    • Tip the bike gently side to side if needed to get the last of the oil.
  4. Reinstall the Drain Plug
    • Wipe any dirt or oil from the mating surfaces with a clean rag.
    • With the crush washer in place, hand-thread the drain bolt back in.
    • Tighten with your torque wrench to 15 Nm (11 ft-lb)–this is critical for preventing leaks without damaging the threads.
  5. Add New Gear Oil
    • Pour in 500cc (0.5 liters) of recommended gear oil through the fill hole. Use a funnel to avoid spilling.
    • Recommended oils: Motul Trans Oil 75W/80W or similar.
  6. Check the Oil Level
    • The 2022 Husqvarna TC85BW has a gear oil level bolt (inspection screw) on the right side of the engine.
    • Remove this screw and ensure oil is at the bottom edge of the hole (bike should be upright and level).
    • If no oil drips from the hole, slowly add more until it just starts to seep out, then re-install the level bolt.
  7. Reinstall the Filler Cap
    • Thread the filler cap back in by hand. Clean up any spilled oil on or around the engine.
  8. Dispose of Old Oil Responsibly
    • Transfer the drained oil to a sealed container and bring it to a local recycling center or auto parts store. Never dump oil on the ground or down the drain.

Model-Specific Call-Outs for the 2022 TC85BW

  • Oil Capacity: 500cc (double-check with your owner’s manual, but this value is confirmed for the 2022 model).
  • Drain Plug Torque: 15 Nm (approx. 11 ft-lb). Using the correct torque is crucial to prevent leaks and stripping the threads.
  • Inspection Screw Location: Right side of the case–add oil until it reaches the bottom of this hole.
  • Recommended Oil: High-quality gear oil such as Motul Trans Oil or Factory-Approved 75W/80W transmission oil.
  • Interval: Change after every 10 hours of riding or as recommended by the manufacturer (consult your owner's manual for race or extreme use intervals).

Additional Tips

  • Always check for oil leaks after your first short ride post-change and re-torque if necessary.
  • Wear gloves to reduce skin contact–used gear oil can be irritating.
  • If you ever find shiny metal flakes in the used oil or on the magnetic drain bolt, monitor for abnormal wear or consult a pro mechanic.
  • Consult the official Husqvarna Owner’s Manual for any specific updates or years with running changes to hardware or specs.

Regular gear oil changes are your best insurance against premature wear and transmission issues. If you need quality oils, crush washers, tools or more advice, MotoSport.com has you—and your TC85BW—covered.
