Schwinn meridian rear drive axle
#1
Recently bought a slightly used 26" meridian trike. While replacing wider tires on the rear, I noticed an issue with the rear drive side wheel hub. The wheel is held on with a nut and single washer. The hub is not held firmly in a location on the axle and is able to slide back and forth on the axle a good half inch even though the nut is tightened all the way down to its bottom threads on the axle. The non drive side hub and wheel has very little play on its axle , perhaps a 1/8 inch and seems to run fine.

While the drive side hub slides back and forth and seems to be creating undue wear on the hub which is a hollow "D" shaped hub.
My question is should the rear axle have an even amount of axle sticking out of the bearings on both sides and thus allowing me to remove some of the play out of the drive side or was the rear axle designed this way for some reason to allow the drive hub to slide back and forth on the axle? To me it seems like if the play was removed the hub would not wallow out from sliding back and forth.
It looks like the solid rear axle is held on by two large nuts on each side seating it to the bearings and frame. Any help is appreciated.

Hey Chuck

Did you find a solution to your hub/axle issue? I also have a used Schwinn Meridian that I converted to 18 speeds. It does not have the play you described (if I understood correctly). Pictures would help. I was searching for replacement hubs (mine have severe external corrosion) when I found your post. I was shocked when I got to the end of it and saw that the poster lives in Bradenton! Which is where I live!

BTW, I really enjoy this Trike Alot, I have 8 other bikes ! But ride the Meridian almost every weekend to tow my Kayak to Palma Sola Bay or to go get groceries. If you want me to take a look at yours, depending on where your at I might be able to OR if you want to look at my trike for reference, just let me know.

Thanks for the reply Bruce. I did get it resolved and while it felt very tight it still had room to tighten more. That took out all the excessive play. I also ride mine down to Palma sola but on manatee ave. I also have a kayak but have not yet made a wheel set to pull it on. I need to do that soon. I made a wooden cargo box but have not added a hitch yet. The cargo box lets me store and lock things such as the lithium battery and tools and gear etc. would be interested in seeing your gear conversion.
Thank you
Chuck

Here are some pics of my Meridian drive train. It was a used trike from a garage sale with ALOT of rust and I used a cheap donar Mountain bike for the gearing upgrades. Used Trailer from Goodwill converted for hauling kayak etc...
