Hi Derek,

I have completed a similar operation with a 3000. I involves removing the rear cover, locating the pully wire brackets (one top, one bottom, a tourch is helpful) and the 2 screws on eachand, I cannot stress the need to loosen these, carefully, just enough to allow the doors to be moved together and re-tightened on the 'new' wire position .The Service manual for the 3000 is available on this site.

If you do not feel 'DIY sufficent' take to your local B&o.

I hope this helps.

Phil

Phil:

Thanks for your reply. I do have the service manual from this site. Where does it explain the procedure for this adjustment?

I know which screws you are talking about. The ones on the top rail are easier to get at. How do I adjust the bottom ones? Do I need to remove the string?

 Also do I need to make adjustments to all for brackets that hold the door in place?

Thanks,

Derek

Hi Derek,

You need to remove the electronic pack to get at the bottom door carriage adjustment. With only 3mm or so gap I would probably leave it alone but if you feel the need then I would only adjust one door. To maintain a uniform gap it is usual to adjust top and bottom door carriers.

On the several times that I have fitted new doors, the gap seems to be wider with the replacements doors fitted. I believe that later models of these machines have rubber buffers in the centre of the carriage slides (as do replacement slides) and new doors are manufactured to achieve a slightly wider gap to take these buffers into account. If that is not the answer, it is indeed strange that the gap grows every time I fit new doors!

This is a bit of a balls aching job and you will probably regret starting it for the sake of a 3mm gap!!

Hi Graham:

Thanks for your reply!

Your describe my scenario precisely. I dove into it this weekend and it was an annoying process. It took me a good hour to get everything the way I wanted it!

Hi Derek,

Sorry for not responding sooner, I was away this weekend. I'm pleased that Graham has come to your rescue, as he helped me through my experience!

It's a job, once mastered you never want to do again!
