Changed the gear oil in both gearboxes, reduction box and final drive box and thought I’d post pictures of it. The reduction gearbox has a drain, small metric allen head and holds 24 ounces. The final drive gearbox doesn’t have a drain so I improvised (shh don’t tell the wife) to remove the fluid, it held 12 ounces. I used Mobil Delvac Synthetic Gear Oil 122035 75w90 for refill from Summit. I always label with date, oil and capacity for future reference, no guessing!
