Regular oil changes are vital to keeping your 2006 Husqvarna TE450 in top running condition. This robust guide from MotoSport.com will take you through the process step-by-step, including all specific call-outs you need to know for your bike.

Tools and Supplies Needed

  • Engine oil (consult your owner’s manual for the recommended type and quantity; reputable synthetic motorcycle oils are ideal)
  • New oil filter
  • Oil drain pan
  • Measuring cup (to check correct oil volume)
  • Contact or brake cleaner
  • 10mm and 13mm sockets or T-handle wrench
  • 5mm Allen wrench
  • Pliers
  • New crush washers (recommended for drain and filter plugs)
  • Rags
  • Rubber gloves
  • Safety glasses
  • Torque wrench

Preparation

  • Start the bike and let it idle for 2–3 minutes to warm up the oil; this allows it to drain better.
  • Move the bike to a well-ventilated workspace and place it on a stand for stability.
  • Remove the skid plate if equipped; this will provide better access to all the plugs.

Draining the Oil

  • Thoroughly clean the area around all engine drain plugs before removal to prevent contamination.
  • The 2006 TE450 features multiple oil drain locations:
    • One main drain plug at the bottom of the engine (beneath the crankcase).
    • One oil screen cover plug toward the bottom/side of the engine.
    • One smaller filter plug near the front left side of the engine (sometimes a composite material).
  • Remove all drain plugs and let the oil fully drain into your pan. Allow several minutes for a complete drain.

Cleaning and Inspecting Components

  • Inspect drain plugs and washers. Replace crush washers if deformed or excessively worn — this helps prevent future leaks.
  • Clean the oil screens/strainers you remove. Use contact cleaner and let them dry fully before reinstallation.
  • Wipe any oil residue from mating surfaces with a clean rag.

Replacing the Oil Filter

  • Remove the oil filter cover (usually on the left side of the engine) using the appropriate wrench or socket.
  • Remove the old filter; note its orientation.
  • Install the new filter, making sure it seats correctly as per the manufacturer’s design.
  • Reinstall the filter cover with a new crush washer and torque appropriately (see below).

Torque Specifications – Husqvarna TE450 (2006 Call-Outs)

  • Both the main drain plug and the oil filter plug require 25 Nm (18.4 ft/lb) of torque. Do not overtighten — overtightening can round off the plug’s hex or damage softer plastic or composite plugs, which are present on some models. Apply even, gentle pressure with your torque wrench for best results.
  • If your oil filter plug appears to be composite or plastic, take extra care: the torque spec remains 25 Nm, so stop immediately if you feel any odd resistance or the hex begins to round.

Refilling with Oil

  • Install all drain and filter plugs, ensuring proper torque and new washers.
  • Add the correct volume and type of oil specified for your 2006 TE450 (consult the owner’s manual; most Husqvarna 450s take roughly 1.1–1.3 liters per change, but always double-check).
  • Using a funnel, pour in the oil steadily and avoid overfilling. Use your measuring cup to verify the quantity.

Checking Oil Level and Final Steps

  • Start the engine and let it idle for about 30 seconds, then turn off.
  • Give it a minute, then re-check the level with the dipstick or sight glass. Add oil in small increments if needed.
  • Look for leaks around all plugs and filter covers.
  • Reinstall the skid plate if you removed it.
  • Dispose of used oil and filter at a proper recycling facility.

2006 Husqvarna TE450 Specific Tips

  • Don’t overtighten the drain and oil filter plugs — the 25 Nm torque spec applies to both, but especially exercise caution if your oil filter plug is the M14 composite type. Husqvarna experts warn that overtightening is a common cause of damage on older TE450s.
  • Verify you have all screens and washers reinstalled; older models like this have multiple oil screen plugs as well as the drain bolt.
  • If your plug’s hex is worn or rounded from previous overtightening, replace it before your next oil change to avoid future headaches.
  • Keep a close eye on the oil level for the first couple rides after a change, especially if your bike sits for long intervals between uses.

Why Change Your Oil?

  • Regular oil changes remove dirt, metal particles, and degraded oil that can prematurely wear your high-performance engine’s parts.
  • The correct oil also protects against extreme heat and hard riding common with enduro motorcycles.

With proper care and regular oil changes following this guide, your 2006 Husqvarna TE450 will remain a reliable, high-performance machine for years to come. Contact MotoSport.com’s experts for questions about oils, filters, or any other maintenance parts specific to your model.
