DE Vere 504 enlarger chassis question

[info@foto-art.nl]

Hi,
I am building up a de vere 507 (504 chassis) and have a question about the chain in the base that is used to change the heads position.

I find that the chain is quite loose, so when rotating the wheel it comes of the sprocket quite easily. (see pics)
At the top there is a plastic thing that can be used to adjust the chain but even in the most left position the chain is to loose.

So i must have done something wrong here.
Does anybody know if the chain is running wrong over the sprocket and plastics wheels???

thanks.

I think you'll find that's normal when it's not fully assembled. The chains are supposed to be locked in place and unable to rotate when the enlarger is disaasembled.

I have a service manual in storage I'll try and find it in the next couple of evenings if you're stuck, I've got to find some other things anyway.

Ian,

The cap that is over the chain has a moveable item to push the chain, but when attached it looks like it is still to loose..
I have a user manual that says you never will have to do something about this... So i guessed am I doing saomething wrong here?

Thanks for your help.
