I would recommend getting a scissor motorcycle jack and have some short 4 x 4 pressure treated posts for spacers. Jackstands and hydraulic jacks work but beware of a sudden hydraulic leak. You will likely need to do some woodworking surgery as well since the current production caster stems may differ plus you are changing out the sizes. Best to talk to Yamaha about this. I found out the hard way that current production on G2 casters have a larger and longer caster stem. Still have not finished the job because of scheduling conflicts but I had the leg off took out the old caster and it was a no go. I purchased a high quality Forstner bit that can be used in a hand held drill which has to be mounted in a drill press type attachment. Normally this work would be easy to do in a workshop on a horizontal boring machine or the correct sized drill press. As pointed out the bigger casters may raise the pedals.
The casters are not exactly cheap and there could be a supply chain backlog. I had to wait 15 weeks and only 2 arrived. 2 weeks later the 3rd one came

Isn't this going to raise the pedals higher off the floor?

I can't answer about the casters and whether you might have to modify anything. Go prepared for all possibilities Drill, bits, screws, plugs, etc
You can make a jack easily enough. I'd go to Harbor Freight or Auto Zone and get a cheap jack. Then make a box for it out of plywood. I made mine from the wood of a reed organ. It's open on the front but quite functional.

Subject: Replacing Casters on a Yamaha G5
I have a client who has a G5 from 1993. He wants to replace the standard size casters that it came with with the big 3-1/2" ones. Two questions:
First, I don't have a Jack-in-the-Box. I assume I'll have to get one?
Second, does anyone have experience doing this on this model? I'm mostly trying to make sure I'll be able to pull off the old casters and put on the new ones without any unforeseen difficulties, such as having to enlarge the hole, etc.
Thank you in advance,
