Here is what I have done with no lift needed:
1.) Go for a quick 5-10 minute ride around the block to warm up the bevel box oil.
2.) Park the Three Wheeler on a slight downward incline if possible with the front wheels higher than the rear.
3.) Remove the drain plug (hex head bolt located directly below the fill plug. Fill plug is the hex socket below the yellow check-mark in this photo).
Note: It will be behind the cross bar brace, but you can reach it with a wrench or smaller sockets.![[Linked Image]](https://i.imgur.com/Fl5oXhJ.jpg)
3.) Remove the fill plug (hex socket below the yellow check-mark example photo) to allow air to enter the box and expedite the drain process.
Note: I pumped some new fluid in there just to push out any extra old oil.4.) Install drain plug.
5.) Move the Three Wheeler to a level area.
6.) Fill up the bevel box until the oil flows out the fill hole (approx 350mL?)

7.) Install fill plug.
8.) Go for another 5-10 minute ride around the block
9.) Repeat drain and fill procedure and enjoy the Three wheeler for another 500-1000 ish miles until you have to do it again.
Note: I think more frequent spending ~$25 on the bevel box oil is good practice and preventative maintenance to ensure clean fluid is in there and better than going too long or unknowingly letting fluid level get too low over time. $25 is better than a few thousand for bevel box replacement
