Panasonic RX-ED77 Cassette Mech Timing
Can anyone help me out with this one please?
Does anybody know, or even better, have any instructions, on how to set up the timing on a Panasonic RX-ED77 dual cassette deck please? The unit in question requires new belts, which I stupidly thought would be an easy replacement. I have the belts and replacement pinch rollers. I have looked on YouTube, but can only find something in a foreign language, which I can't follow tbh. If anyone can give me some advice on this I would really appreciate it. Thank you |

Don't know if this will help, but apparenly it uses an AR2 cassette mechanism series deck.
I've looked at the places I know of for a manual, but can't find one. |
Re: Panasonic RX-ED77 Cassette Mech Timing
Probably will not help much but the RX-ED77 Service Manual can be downloaded from a couple of sites such as manualslib.com

Thanks for your reply. Yeah, I've got the service manual but, unfortunately, it doesn't cover the cassette mech. Mark |
Re: Panasonic RX-ED77 Cassette Mech Timing
The service manual exploded diagrams do show the cassette mechanism parts but will not really help in terms of fitting parts.
I see some posts in the tapeheads forum which indicate that the referenced AR2 cassette mechanism is Panasonic. David |
Re: Panasonic RX-ED77 Cassette Mech Timing
I can’t recall any manual showing how to fit belts. The exploded diagram will give clues about the way its assembled. You then have to work out how to do it. The manuals are meant for service engineers who should have a good idea what to do.
Can I ask what you mean by timing? |
Re: Panasonic RX-ED77 Cassette Mech Timing
I never knew about the tapeheads forum. Thanks. I have just joined :thumbsup:

Maybe timing is the wrong wording, but I couldn't think of anything better. Mark |

Re: Panasonic RX-ED77 Cassette Mech Timing
There are probably holes or marks on pairs of gears which need to be lined up in a given mode - not very helpful without specific information, I grant you, but they may provide a clue.

Re: Panasonic RX-ED77 Cassette Mech Timing
There’s a ‘neutral’ position where the flywheel can turn without driving the mechanism. This corresponds to the stop position on most decks which run the motor at all times. I doubt that you will need to remove any of the gears, if fitted, in order to fit new belts. On many decks there will be a solenoid to start the drive to load the mechanism into play etc. assuming this deck has touch buttons to operate it.
