Well, it finally happened. My pint sized Muni partner has wiped out the
bearings in his 16" MUni. They squeak, they grind and they’re generally
void of any grease at all. Does anyone know what size bearings I should
purchase? He has a 16" United with lollipop style holders. I’m guessing
35 mm? If anyone has any advice on how to properly replace them it’s
appreciated as well. I’ll purchase a crank puller. Do I need any other
You will need a bearing puller to get the lollipops off of the axle. unicycle.com will have all of the tools you need and the lollipop bearing assemblies. If you have to buy the bearing assemblies from unicycle.com anyway it makes sense to get all the tools from them, too. It will save you a trip and keep you from wondering if you’re buying the right tools.

Right, but what size bearings for the 16" lollipop assembly, 35mm or
Just call them up, 1-800-unicycle, and tell them what you want to do. They’ll tell you the right bearing size and send you everything you need, including the tools to do the job. Ask for Amy, she’s an ACE mechanic there. And tell her I sent you.
I had lollipop bearings on a Zephyr. The frame cracked and I wanted to save the bearings. I drilled three holes in the backsides of the lollipops to access the outer bearing race and used a drift punch to get the bearings out unharmed. The lollipops were essentially unharmed also, just slightly ventilated. I saw no way to use a bearing puller to extract them from the lollipops. But then I am not a GENIUS like John Childs.
The bearing is press fit in the lollipop so the bearing is going to need some force to be removed from its happy home.
I put a nickel (5 cent coin) over the hole in the bearing. The arms of the bearing puller grab on to the outside of the lollipop. The plunger on the bearing puller pushes on the nickel which pushes on the bearing. The bearing gets pushed out of the lollipop holder. So instead of a bearing puller you have a bearing pusher.
Another way to look at it is that you’re pulling the lollipop off the bearing. So now it’s a lollipop puller instead of a bearing puller.
Being naughty to my almost-seized up bearings in the Pashley lollipops, I put the holder on top of a vice and pounded them out with a hammer and tube centered on the inner bearing race. Not only did they come out (with a lot of beating!) but the pounding made the bearings nice and smooth again! But I threw them away anyway…
