How hard of a press fit is it? Hammerable, or no?

I have no clue. Brass is pretty soft

Stick the brass bushing inside the freezer for 15 min. The brass will contract in size . Then Heat up the Spur with a Heat gun or hair dryer. The Spur will expand. So it is very hot to the touch, use gloves to handle it. Then quickly insert the brass bushing right out of the freezer. Should fit in/ slide in easily enough. Try that. As both metals get to room temps, the bushing should become nice and snug.
Let us know how it works out.
I would imagine the brass bushing in this application should be a very tight fit for best operation.
Brass Oilite bushings are soft. I would Not hammer it.
And No need to.
My 2 cents.

One of my spur got toasted my gearmesh was too tight and it ruined my brass bushing. I don't think it would be too hard to get one machined to spec or find one online
Wish arrma sold that part alone. Such a waste

Amain decided to send me a new spur gear anyway. They got told by horizon it wasnt normal. Here is the new spur gear.
It can be a real issue if someone doesn't have the tools to press fit the part in. Still a bit bummed by this but i cant complain. Got a free spur for asking if it was normal for the spur to come seperated from its bushing
