• Milky or grey gear oil showing water has got in
• Metal glitter or paste on the drain plug magnet
• Vibration and noise that persists after the propeller is checked
• Gear oil level dropping between checks

🛠️ Service Notes

• Five lower gear units in this group cover the ratios and all weigh between 27.216 kg and 28.032 kg, so weight cannot separate them - order strictly by ratio
• The number it replaces was listed as a remanufactured unit, so confirm with us whether the current number is supplied new or on exchange before you order
• At over 27 kg this is a freight item, and the drive oil, seals and propeller hardware should be renewed at the same time
