Bomb proof Model E, not

Post by le grand fromage » August 14th, 2023, 5:19 pm

Just a heads up for all those with a model E, check underneath where the front leg assembly attaches to the box frame.

Went to lift mine out of the garage for a clean and maintenance and the front leg assembly dropped down. Only held onto the box frame by 2 bolts not 4 as the flange on top of the leg assembly, nearest the 'seat', had sheared off. Obviously been happening over time and completely gave up the ghost as couldn't support the weight of the front legs when I lifted it off the ground. Contacted C2 as hoping it was a structural fault similar to early model D's and warranted a free part, but unfortunately not.

Managed to fashion a repair with some angle iron, mainly as I thought £150 for a new front leg assembly was a bit steep. Will probably end up paying it eventually :roll:

Common problem with the model E.

The legs are longer than the D and have a lot of leverage, I wouldn't recommend one for those that row at pace or have bad form.

Its common for those fasteners to come loose even on a Model D, they need to be checked at regular intervals in high use situations.

Screws should be Loctite in or use a washer and spring washer minimum.

My RowErg manual actually said to do so every 250 hours of rowing (see https://www.concept2.com/files/pdf/us/i ... shOnly.pdf).

To make sure that I understand properly, referring to the Step #1 image in the PDF file at the link above, was the issue with the flange in the leg assembly that's closest to the footrests? (i.e. the one on the left side of the image)

Thanks

I have seen the frames shredded on these if the fasteners come loose.

There is only strength with everything bolted together. If it comes loose the threads get stuffed and the metal gets twisted, its only aluminium. A favourite over here is for people to then try and fit a metric screw into the 1/4 UNC thread.

You can literally scrap a frame if the problem is not fixed in time.

Yes that is the correct flange.

And, for clarity for those comments that suggest loose bolts. The bolts were tight, ie still connected to the box frame. The flange sheared in two locations 'inside' where the bolt holes are on both sides such that the two bolts were no longer holding the front legs to the box frame.
