Step-by-Step Guide to Changing Your Viar Gearbox Oil

Alright, so you know why it's important and where to find the capacity. Now, let’s talk about how to actually change the gearbox oil. Don't worry; it’s not rocket science. But safety first, guys!

Tools You’ll Need:

• New gearbox oil (check your manual for the correct type and amount)
• Wrench or socket set
• Drain pan
• Funnel
• Gloves
• Rags or paper towels

Steps to Follow:

1. Prepare Your Viar: Park your Viar on a level surface and engage the parking brake. Let the engine cool down completely before starting. Gearbox oil can get hot, and you don’t want to burn yourself.
2. Locate the Drain Plug: Find the drain plug on the gearbox. It’s usually at the bottom. Place the drain pan underneath the plug to catch the old oil.
