I bought a three wheel adult 6 speed non motorized trike for exercise and I need help putting it together.

It doesn't appear to exist. These items are made in China where selling them and the odd spares is the name of the game.

This is a difficult operation, you can try a video from Utube. But the best solution is take your trike to the local bike shop.

I just put my Maridian together and two days later hit a small pothole on the left rear doing about 15mph so I called Schwinn and they replaced the wheel with no hassle. They have mnfg standards and a lifetime warranty...

Yes. Contact your local bike shop

The speedometer reading change when pushing the button means that this button was probably installed to recalibrate the speedometer. The size of the rear wheel was probably reduced, so the speedometer needs to be calibrated for the smaller wheels. As long as the speedometer reads right, I wouldn't worry about it. As for the oil level, it shouldn't be changed. There's marks on the dipstick indicating how much oil is needed.

That's too subjective. You be the judge.

you need a new axle kit, and a cog removal tool. They used to be a Huret dearailleur if I remember right. I know a varsity never had Shimano. I think you may be better off buying a new rear wheel (it is usually less money than having to rebuild the axle) and let the bike shop do the change over, it is well worth it. You wont have to deal with the brakes,check the cones etc. Why did you have the Meridian adult trike on, and you have an old 10 speed Varsity? Kind of confusing.
