Question: I have the same problem - the O washer opening is smaller than the pipe it goes on.  It does NOT fit!  Help!
Document: I have been using this for about a year now, and love it! It is smaller than some of the other ones, but that hasn't been a problem. Both my husband and I are smaller people though (105, and 145 lbs). It does it's job just great. We have had to tighten the screws once this year, when it got a little loose and wiggly.
All the parts were there and putting it together was smooth and the instructions were clear and straightforward. No squeaking noise from the machine and minimal activity noise as well! The stride seemed to be a little short for me even though it is one of the longer ones out of the cheaper machines, but it does not cause any problem when working out and it seems to fit my height(5'4") just fine.
this item is a good value, but assembly is brutal. the parts and screws did not fit together very well, and when it was shippped the electrical cords in the center shaft were pinched and cut. i had to splice together all of the wiring to make it work. why? because after opening the package piece by piece with all of the individually wrapped items and styrofoam packaging... what a pain it would be to repack this item and return it?
Squeaks loudly after about 3 months of use. I did grease the moving connections per instructions - no help. Now it just squeaks all the time.
It is high quality, was easy to put together (with help) and it works beautifully. I have already lost weight and it is fun and easy to use the Schwinn Elliptical A40!
A backlight would help. I'm not sure if a booklight shining on it would help or not. We are going to try that this weekend. Overall, a good product for the price. I would purchase again. We purchased from Amazon as opposed to other local locations for the "no tax and free shipping" and it saved us in that department since it's about the same price everywhere, within a few dollars.
Great out of the box when working. Not even two month's later it starts making a clanking noise like it will break. Support is through another fitness company and is of no help whatsoever. I have had a ticket open for a month getting the run around. Plus, even though it is under warranty,  the deal is YOU have to fix it yourself while speaking to support on the phone. Just a bunch of garbage.
(BTW...the warranty only covers the part..not labor)  They think it's in the rod....where the pedals connect...or where the handles connect..could be both....so how do we replace the whole rod??? In the end...I use it with the "crick". I'm stuck with this thing...way to big to return..at my expense. DO NOT BUY IT!
It weighs only a couple pounds less than me.PRO's- Stable, not too space consuming, and a great workout.CON's- Just for looks fan, barley puts any air out, Pulse grips are incorrect, and frame was a bit bent when received.All in all I would buy this machine again for the price.DO NOT BUY!! !
DO NOT BUY THIS unless you want to waste your time building and deconstructing a heavy bulky machine.
Answer: yes
