If you own a 2011 Husqvarna TXC511, regular oil changes are essential for engine health and performance. This detailed guide walks you through all the steps, specific notes for your model, and the tools needed. Presented exclusively for MotoSport.com, this is your one-stop DIY reference for oil changes.

Tools and Supplies Needed

  • Socket set (including 17mm and 22mm sockets for drain bolts and filter cover)
  • Allen keys/hex wrenches (for oil filter and screen covers)
  • Oil catch pan
  • Funnel
  • Replacement oil filter (per manufacturer specification)
  • Quality 4-stroke motorcycle oil (consult owner's manual for viscosity and capacity; typically around 1.3 to 1.4 liters for this model)
  • New oil filter O-rings and crush washers (strongly recommended)
  • Gloves and rags

Preparations

  • Start and run your engine for about two minutes. Warm oil flows and drains easier, carrying away more contaminants.
  • Turn off the bike and place it firmly on a stand so it's upright and stable.

Step-by-Step Instructions

  • Remove the skid plate (if equipped) to gain access to all drain bolts and oil filter covers.
  • Locate the drain plugs:
    • This model features multiple drain plugs and oil screens, all conveniently clustered underneath the engine case. Make sure your oil pan is positioned to catch all draining oil.
  • Remove the main oil drain bolt using a 17mm socket. Let all the oil drain completely into your catch pan.
  • Remove the oil screen covers (small covers secured by Allen bolts) and carefully pull out any mesh oil screens. Clean the screens thoroughly with solvent or brake cleaner and inspect for metal fines. Replace if damaged.
  • Remove the oil filter cover using a 22mm socket. Take out the old oil filter. If reusable, clean the filter; otherwise, replace with a new one.
  • Inspect drain plug/magnet: Wipe the magnetic tip and check for significant metallic debris. Some fine paste is normal.
  • Replace the crush washers (on drain bolts and oil screen covers) with new ones before reinstallation to ensure a proper seal.
  • Reinstall the oil screens, filter, and all drain bolts. Tighten them to the torque settings stated in the owner's manual (do not overtighten; aluminum cases can strip).

Refill With Fresh Oil

  • Remove the fill cap (top right/superior side of engine case).
  • Insert a funnel and carefully pour in the recommended oil type and amount. Husqvarna generally recommends about 1.3 – 1.4L for this 511cc engine, but double check your owner's manual to confirm exact capacity for 2011 TXC511 (common call-out).
  • Stop periodically to check the oil level on the dipstick or level window. Do not overfill. Overfilling causes smoking and can damage seals .
  • After filling, reinstall the fill cap and wipe away any spilled oil.

Final Steps

  • Start the engine and let idle for 1–2 minutes. Inspect for oil leaks at all drain plugs, screens, and filter cover. Shut down and let oil settle.
  • Recheck oil level on dipstick or sight glass and top off if needed. Ensure that oil is between the minimum and maximum marks.
  • Reinstall the skid plate and clean up your workspace.

Special Tips for the 2011 Husqvarna TXC511

  • This model's oil system uses multiple drain points and mesh screens for optimal filtration, a unique feature compared to many bikes (don't skip screen cleaning.) .
  • Always inspect and clean the magnetic drain plug – a little metallic paste is normal; large chips or shavings can indicate internal distress .
  • Use only high-quality motorcycle-specific oils to protect the wet clutch and engine internals.
  • During reassembly, thread all bolts by hand first to avoid cross-threading the soft aluminum case
  • Never reuse crush washers as they easily deform and may not seal properly.

Disposal and Maintenance Logging

  • Dispose of used oil and filters responsibly; most auto parts stores or service shops accept waste oil.
  • Record the date and hours on your maintenance log. Frequent oil changes (every 10–15 hours of riding is typical for high-performance dirt bikes) are vital for engine longevity.
