Part 4: Cleaning the “Black Goo” – The Most Critical Step
Inside, you will likely find a black, tarry substance smeared around the motor pulley and flywheel. This is your original belt. Do not touch it with bare hands – it stains everything.
- Remove the old belt: Use tweezers and toothpicks to extract the sludge. Be patient.
- Clean the pulleys: Dip a cotton swab in isopropyl alcohol. Scrub the motor shaft pulley, the large flywheel groove, and the counter pulley until all black residue is gone. Use a toothbrush for the gears.
- Clean the pinch rollers: Locate the two small rubber rollers (one for each direction of auto-reverse). They should be dark black, not shiny. Clean them with alcohol until the friction returns. If they are hard or cracked, they need replacement (a harder repair).
- Remove old grease: Look for white or yellow grease that has turned into wax. Scrape away old grease from gears with a toothpick and re-lubricate with plastic-safe grease (like Super Lube 51004 or lithium grease). Never use WD-40 – it destroys plastic.
