How to Change the Oil in a 2023 Husqvarna TC50 — MotoSport.com Exclusive Guide

Shop parts for a 2023 Husqvarna TC50 Dirt Bike.

  • Estimated Time: 30–50 minutes
  • Difficulty: Beginner to Intermediate
  • Recommended Frequency: Refer to the owner’s manual — typically after every 10 hours of riding, or as specified for your conditions

Tools & Supplies Needed

  • Funnel (for adding oil)
  • Measuring cup (accurate oil quantity is vital)
  • Torque wrench (a 13mm socket required for drain plug)
  • Drain pan or suitable container (to catch old oil)
  • Shop towels or rags
  • New gear oil (confirm oil type and quantity from your Husqvarna TC50 owner’s manual)
  • Replacement drain plug crush washer (recommended with each oil change)
  • Gloves (optional, for cleanliness)

Preparation and Safety

  • Ensure the engine is warm but not hot before beginning. Warm oil drains more thoroughly but avoid burns.
  • Work in a well-ventilated area, away from sparks or flames.
  • Place the bike solidly upright on a stand, on a level surface.

Step-by-Step Instructions

  1. Gather and Prepare Tools
    Lay out all tools. Put the bike on its stand so it’s stable and vertical. Prepare the drain pan under the engine.
  2. Remove the Oil Drain Plug
    Locate the oil drain plug under the engine, near the gear case. Use a 13mm socket and torque wrench to loosen and remove the plug. Let the oil drain completely into your pan.
    Pro Tip: The drain plug is magnetic and designed to catch metallic particles; inspect and clean it upon removal.
  3. Clean the Drain Plug and Engine Surface
    Clean all residual oil, debris, and metal shavings from the plug and magnetic tip. Also, clean the mating surface on the engine where the plug seals.
  4. Replace Crush Washer
    Always install a new crush washer or sealing ring to prevent leaks.
  5. Reinstall and Torque Drain Plug
    Thread the plug in by hand first to avoid cross-threading, then use the torque wrench to tighten it to the specified torque:
    • M6 plug: 6 Nm (4.4 lbf.ft)
    • M12x1.5 plug: 20 Nm (14.8 lbf.ft)
    Refer to your owner’s manual for confirmation of the correct torque specification for your specific plug.
  6. Add New Gear Oil
    Double check your bike’s oil type and capacity. Use a funnel to prevent spills. Add the exact quantity specified in the owners manual.
    For the 2023 TC50, refer to p. 114 in the official Husqvarna owners manual for precise volume specification.
  7. Level Check
    Wait a few minutes to let oil settle. Use the level-check procedure outlined in your manual. Add more oil if needed, being careful not to overfill.
  8. Final Steps
    Reinstall the oil fill cap. Wipe down the area. Dispose of oil and oil-soiled materials in accordance with local environmental regulations.

2023 Husqvarna TC50 Model-Specific Call-Outs

  • Oil Type & Capacity: Always use the oil type and exact amount specified for the TC50, as improper oil can cause clutch or gearbox wear.
    Tip: Changing the oil with the bike upright (not leaned) ensures an accurate fill and reading.
  • Magnetic Drain Plug: Inspect the magnetic tip for metal shavings. A small amount is normal, but excessive debris may signal internal wear.
  • Torque Settings: Do not overtighten. Stripped threads in the crankcase are expensive to repair and proper tightening is vital to prevent leaks.
  • Crush Washer: Replace the washer with every oil change to maintain a seal.
  • Clean Work Area: Dirt and grit in the oil fill or drain areas can cause internal engine damage. Clean thoroughly before removing any parts.
  • No Oil Filter: The TC50 uses only oil changes and a magnetic drain plug—there is no physical oil filter to service or replace.

Proper Disposal and Aftercare

  • Dispose of used oil at approved recycling centers or auto stores. Never dump in the trash, pour down drains, or onto the ground.
  • Double check for leaks after the first ride post-change. If you see leaks, recheck torque and crush washer integrity.

Frequently Asked Questions (For the 2023 Husqvarna TC50)

  • Can I use automotive gear oil?
    Only use oil brands and viscosity grades listed in your Husqvarna manual to avoid premature clutch or gearbox wear.
  • How do I know if I used the right amount?
    Refer to the level check procedure in the manual. Overfilling can cause foaming and leaks, under-filling can cause component wear.

Tip: Replacing the oil regularly is one of the best ways to extend the life of your Husqvarna TC50. Perform this job carefully — a little extra attention now saves big repairs later. For more OEM parts, expert tips, and exclusive deals, always trust MotoSport.com.
