Are you sure, the belts are correct and fitted correctly?
Did the seller include mounting instructions and did you ask for advice and support?

There are SO many wrong belts on the market.
Most are mere standard belts, pretty much useless in any B&O, and I wonder how those sellers can stay in business.

Well, as I said, I ordered them from Thakker in Germany - whom I understood to have have a good reputation.  

I didn't receive any mounting instructions, though - so I mounted them the same as the worn ones (only the larger flat belt was stretched - all the others were intact and still seemingly fine really).

 

Thanks for your help!

I purchased a BC3300 belt kit from Dillen a few years ago. He included detailed instructions along with the kit. I recommend you ask him for a kit to replace the previous one you tried.

Does both tape reels rotate when play is activated - (even if just for a brief moment)?

Martin

There is no movement at all when play is pressed - although both rotate fine when fast forward or rewind are pressed.

Just to add - I have just tried it without a tape at all, and when I press play the left hand wheel rotates fine, and seemingly at the correct speed.

Also, I have noticed that when I press play with the tape inserted it looks like the whole tape is being pushed very firmly against the top of the slot - so I'm wondering if the heads are going tight up against the tape and stopping it from moving.

Thanks for the help!

If i read that correctly,the LEFT wheel rotates???

the right one should rotate, together with the capstan in play modus, if the left one rotates (and i guess you mean the pickup wheels) chances are the belt is not mounted correctly, which could also explain the fact that the mechanism turns off after about a second because it thinks it has reached the end of the tape...

 

Maybe this will help"/forum/general-discussion-and-questions/looking-for-beocord-3300-service-manual

 

Sorry, you're correct it is the right one that rotates, NOT the left - not sure why I wrote that... I know left from right normally... lol!! 👍

 

Thanks!

Thanks for the link, I mounted the belts exactly how Iit shows in the last photo.  I assume this was correct - as his is working.

Is it possible to set how far in the heads push to the tape?  I still think this could maybe be the reason, it does look overly harshly 'gripped' if you see what I mean? 😮

Thanks!

Ben.

If your deck has two leaf springs, one each side of the tapehead, make sure they slide in above
the tape cassette. If they hit on the edge of the cassette, play cannot be engaged correctly.
