I've got a new-to-me Jantar 3 that was previously sitting in its trailer in humid Houston for 10 years.
I'm trying to remove the axle for the main gear in order to change the tire and fix the brakes.
I've removed the bolt/nut on the left and right side that would retain the axle. Beating on it from either end was not successful at getting the axle to move. I'm not even sure that this axle (slotted on both ends) doesn't need to be unthreaded out.
Before I get rougher with it (rotation and beating along axis), I was wondering if anyone had any hints as to how it should be removed.
Believe this is my first post. Looked for how to post photos, but can't find it, sadly. Would have been helpful for this.
Thanks,
Mike Pollard

I run the SZD-55 users group at https://groups.io/g/SZD-55usergroup but I've searched and there is nothing specific on wheel removal (there is the 55's TSM with exploded view). There may be a users group for the Jantar that could help - does anyoneknow if there is? There wasn't one for SZD-55 that I could find, and so I started one (free on groups.io), we now have 38 members (about 110 built).
In 2013 on r.a.s. there was a note:

Brakes will be part 2. I pull the handle, the lever moves but the wheel is still free to rotate. Once I get this apart, I can see if some correction needs to be made. I sure don't want to count on landing short at our field every time and not need

MikeI had a Jantar-1 (19m) years ago, which I recall had the same or very similar wheel. A light tap with a suitable drift should do it, otherwise you just need a bigger hammer!

I want to thank all of you for your responses. Good info. No bashing, insulting or grossly off topic stuff like I've seen in so many other forums. Must just be better people :) My fancy screwdriver is being reviewed by a machine shop. In the mean time,I've ordered a shaft with a keyway cut in it and some key stock. Some grinding will be required, but think it'll be a good second attempt at getting this thing out. The best part is I'll have it for this weekend (I'm unfortunately not retired yet). If it

Axle came out using a "bucking bar" of wooden posts and a larger hammer. I was ready with the heat gun, torch, fire extinguisher and a defeatist's expectations though. Took the wheel assembly home to look at in more detail with coffee hopefully

Mike,Robert,
The best option I think is a brake retrofit kit available from TOST. It can be purchased from Wings & Wheels https://wingsandwheels.com/conversion-kit-jantar-swift.html
Hydraulic brake in my SZD-48-3 was installed by Williams Soaring Center. Original wheel was replaced with Cleveland .
