- 0.8 liters (27oz) of SAE 10W-30 engine oil
- 8mm Allen wrench
- Oil drain pan
- Funnel
Instructions:
Preparation:
- Place the motorcycle in an upright position, preferably using a center or paddock stand.
Draining the Old Fluid:
- Locate the transmission fluid drain plug on the bottom of the engine. It is usually an 8mm Allen head bolt.
- Place the oil drain pan below the drain plug to catch the old fluid.
- Use the 8mm Allen wrench to loosen and remove the drain plug.
- Let the old fluid drain completely into the oil drain pan.
Refilling with New Fluid:
- Once all the old fluid has drained, put the drain plug back and securely tighten it.
- Locate the transmission fluid fill plug on top of the engine or on the side of the engine cases. It may also have an 8mm Allen head.
- Remove the fill plug and insert a funnel into the hole.
- Add the fresh SAE 10W-30 engine oil into the funnel. You will need to add about 0.8 liters (27oz) of new oil.
- Add the oil slowly to prevent air bubbles from forming.
Checking the Oil Level:
- Once the oil is added, start the engine and let it run for a few minutes.
- Turn off the engine and wait a few minutes to allow the oil to settle down.
- Use a dipstick or look through the sight glass (if it has one) to check the oil level.
- The oil level should be between the "Full" and "Low" marks on the dipstick or sight glass.
Cleaning Up:
- Once the oil level is correct, remove the funnel and securely replace the fill plug.
- If you accidentally spilled oil on other components of your motorcycle, clean them up immediately.
- Properly dispose of the old oil and the empty container according to your local environmental regulations.
By following these steps, you have successfully changed the transmission fluid on your Honda CR 125. Regular maintenance, including changing the transmission fluid, helps keep your motorcycle in good working condition and prolongs its lifespan.
