The headset bearings on my rad runner 2 have seized.  The lower sealed bearing case wont turn. I pulled the stem, but I can't remove the cups or the encased bearing cages.  Does anyone have a tip on how to get them out of the frame? 

The upper bearings are crunchy.  The lower bearings wont run at all.

The fork stem is very rusted mid stem directly across from two holes in the frame.  I think moisture sat in the frame tubes and escaped out of these holes into the stem where they rusted the steel fork stem.  The rust spread, even some of the aluminum is corroded, into both encased bearings.  The lower bearing cage also had to deal with rust falling onto it.  It took some cleaning for me to even be sure that there was a bearing cage at the bottom.

My biggest problem now is that I can't remove the encased bearing cages to see if they can be cleaned and greased. I can't even remove them to replace them.

Service & Repair / Battery Slot Burned Out
May 30, 2023, 02:27:40 PM
Hi,

I have had on of the slots on the battery burn out.  I notice the issue because the battery was exceptionally difficult to remove from the tray.  It was melted together.  The slot contact somehow failed and melted the plastic housing around it.

I am trying to figure out if this is a Warranty issue, but I can't get RAD to respond.  I issued a customer service request and they closed it without talking to me.

Has anyone seen this issue?  Any advice on how to reach RAD for an answer on Warranty question or what I should do?  These batteries are pretty expensive. If it is not warranty, then I'll look into fixing the part that failed.  The batter still seems to charge and work, just this faulty slot.

Service & Repair / Rad Wagon 4 Freewheel Cleaning
March 20, 2023, 01:40:03 PM
Hi,
I just found this forum from Ryan's youtube posting on replacing the rad wagon 4 motor.

I am finding I need to clean my freewheel.  The pawls are no longer engaging.  I had some trouble early in the winter with the freewheel not spinning freely, but I managed to add enough Phil's tenacious to get it moving again.  Maybe I added too much because the pawls seem to be stuck now.

I avoided cleaning the freewheel earlier because I heard I needed a special tool.  Now I am researching that special tool and the only one I can find is the specialty tool from Bolton that is currently out of stock.

Is there another option?
