Brompton owners

I got my biggest mallet out and hit the shite out of it.
Also the rear triangle bolts are rounded. Fucking thing.

Get some Plus Gas in there. Magic solution to seized stuff.

What rear bolts? Hinge?

silver please

The hinge bolts are meant to be drilled out when replacing anyway

Hinge bolts can be drilled so no sweat there!

You need a big metal hammer and a punch rather than an Allen key. The force required is uncomfortable.

This do?

Why is my T5 chain tensioner like this:

... when it's supposed to be like this(?):

Admittedly I've taken it apart, so I must've assembled it wrong. Before the tension was already low, but now it's basically unusable. I can't figure out what I did wrong, since the spring can only be mounted in one way. Is it worn out maybe? I fitted it in the correct slots in both parts.

It's a common problem for first time Bromtpon owners (speaking from experience)

Watch this, it should be able to fix the correct position for the rear arm:

Brilliantly explicit video

I have the punch, will get a bigger hammer.

I've watched the whole video, but I don't think it is related to my problem.

See how without the chain on the lower jockey wheel in my first picture, my tensioner arm is in the 4 o'clock position, whereas it should be in the 11 o'clock position like the second picture. There is no tension on the tensioner arm when I put the chain on the lower jockey wheel.

I'm not familiar with that paritcular design, but presumably you need to take it apart, and - with the spring engaged -twist it backwards past the stop as you reassemble it, so it has some tension in it.

Have PM’d you!

its old af, so possible some wear, but unlikely on the spring. the tension should be pushing the long arm / idler wheel clockwise, maybe you have got the spring caught or over tightened the main screw?

Checked the spring multiple times. It's in the slots. The arm can swing freely. There is just no tension on it. Pretty dumbfounded to be honest.

I think the spring is bent in its (counter) rotation direction. I don't really see another option. The coils are kinda wonkey as well.

I can send you over a new spring if you reckon that might do the trick?

I'm in the Netherlands so I wouldn't bother. Thank you kindly though!

Mine looks like this. What do you think?

I think the bent pieces should be more opposite of each other, like this:

aye should be "looking" at each other!

I may have the opportunity to get a brompton via cycle solutions, but does anyone know if and when there will be stock?

thanks lol

I've got a bunch of spares if anyone wants them. Just come down and pay whatever you want. Enclosed pics.

Other thing I've got is a Brompton Diagnostic kit for the electric stuff. If anyone is interested, give me a PM.
