Stiff seat

Post by NHANORAK » January 6th, 2015, 6:09 am

I purchased a new Model D just before Christmas and found the seat does not roll anywhere near as smoothly as the previous model C I used. I've tried spraying a bit of 3 in 1 oil on the rollers under the seat, but it still doesn't roll smoothly. Would you normally expect the seat on a C2 to go from one top to the bottom of the rail with a gentle push, or was I just lucky with my previous model C?

Any advice on getting the seat to run more smoothly would be greatly appreciated.

I'm accustomed to see the seat carriage on my model D roll fwd to the hinge cover without assistance. Same on the crappy machines at my YMCA gym. Jack

Check the seat is the right way round (the lump should be at the front and the indentation should be at the back).

Loosen the bolts on the seat rollers.

Seats in the gym are probably worn from lots of use. If you like that feel, though, it can be changed. The tightness of the seat is adjustable - three holes are provided for the bottom rollers. See this pic: http://www.concept2.com/files/pdf/us/in ... ematic.pdf You would move the rollers to what is called "looser hole" on each side to get the loosest seat.

Certainly there is some variation in how snug the seat assembly is on the rail, thus the different hole options to fine tune the fit. Before you start taking it apart, sit on the seat and carefully reach down and feel whether the bottom rollers are turning when you move the seat. If you can stop them from turning then there's really no need to loosen the fit. C2JonW

Sounds like you have bits of debris on the seat rollers, simply put a damp cloth over your finger and touch the rollers while moving the seat left to right to clean them.

If its a "New" machine then its unlikely it already has bearing issues. The seat is a little noisy as you would expect with one hard surface on another but it should feel silky smooth and roll from the end on the slide to the foot stretchers by itself.

I give the rollers a quick clean before every row to get the "Black" off them, just dust in the air landing on the uncovered slide is a problem over time.

Don't oil the slide, your encouraging the rollers to skid rather than turn like they should.

Thanks for the responses.

My seat is the right way round. I tried loosening the bolts under the seat, but while it rolls easier, it doesn't roll to the front as in my previous C2.

The link to the diagram is very interesting, but before taking the bolts out fully, I just wanted to check I'm reading this right. I need to take the bolts out of the middle hole, where they presumably are at present and move them over to the looser hole?

Are the front legs on the right way round?

Sorry not following what that refers to, or how I would check it.

The wheels are to the FRONT of the rower and the pads sit flat on the ground.

Putting the front support arms on the wrong way around with cause havoc with the slope on the slide.

This creates a gentle slope towards the front of the rower so the seat should just roll forward when you get off.

Users of new indoor rowers may find that the seat carriage does not move quite as quickly as a machine that is several years old. This may be due, in part, to the factory "tightness" of the rollers as described in previous post. A slight sluggishness may also be due to the grease in the bearings. The bearings in new seat rollers are packed with a medium viscosity grease. Over time, the grease can thin out or dry out completely. An ungreased bearing may wear more quickly, but it will also spin more freely without grease to slow down the movement of the balls. This phenomenon is exaggerated by cold weather. A rower in an unheated garage might have a very sluggish seat carriage until the machine is used for some time and the grease thins out.

They are the right way round, wheels to the front. I just connected the two pieces together when they arrived.
