Philips D8534 help needed - UK Vintage Radio Repair and Restoration Discussion Forum

I need help dismantling the cassette mechanism of the Philips Boombox D8534. I need to replace at least one of the "cheese" gears which has missing teeth affecting the take up clutch mechanism. I cannot see what is holding the 2 large plastic assemblies together and therefore preventing access to the gear wheels. I have removed the cassette mechanism from the case. I have the Philips exploded diagram, but that does not help.

Have managed to prise apart the mechanism and remove the broken gear wheel. I have ordered a replacement from Germany.

If you need copy of the service manual, I have the OEM paper one that I could scan and email to you. PM me if that would be of any help, but it'll be 2 to 3 days before I can get it scanned.

Thanks Dave, I have downloaded the service manual, but it does not indicate how open the assembly to replace gear wheels. Back in the day I suppose you were supposed to replace the whole cassette mechanism if there was a fault. Thanks for the reply.
