Harman Kardon hk 100m belt replacement help

[foofiebeast]

Greetings all,

Sorry this is such a simple question, but I'm trying to get this done and I think i'm just about there!

I picked up an hk 100m a few weeks ago. Great physical shape, but playback auto stops after a few seconds. Opened it up and poked around and eventually figured out the belt going from the take up reel to a spindle that connects to the counter had given up the ghost.

If I manually move the counter wheel playback continues fine, so I think replacing this one belt should get me back up and running. The belts I have are too thick though and don't quite fit- and from the remnants of what's left I can see it' was a pretty skinny square belt. I believe the ones I have are 1.5mm thick, the existing band doesn't look much more than half that.

Using the repair manual I can see it is reference number 718, which is part number 2642-01454, but is there any way to use this part number to actually track down the belt I need?

I've had pretty mixed luck with ordering belt "sets" off sellers claiming to have the right ones, and would rather avoid paying a premium if I don't have to. Any help would be greatly appreciated!

Can you measure the thickness of the old belt? You can use a string to figure out the length.

Maybe you can confirm this one will work? (no affiliation).. https://www.turntableneedles.com/ha...quare-drive-belt-sbo6.0-harmon-kar-2642-01454

According to my PRB cross reference that machine uses belts FRX11.0 (larger, flat belt), SCY4.2, and SCY6.0 (smaller square belts). Your part number crosses to the SCY6.0 belt.

The one I linked is SBO6.0 - .039" x 6.0".
SCY6.0 is .035" x 6.0". For a counter on a cassette deck, probably either would work if the 6.0" part is correct. That's why I suggested using a string to check the length.
