My buddy (source of the spare 560SEL cluster) was having clock troubles so I told him I'd replace the capacitors in this one. I did the same for the 300SD as the cluster was on my desk. The procedure is pretty straight forward, just be careful with the units.

Step 1) Remove clock/tach pod from cluster

Step 2) Remove circled screws and desolder as indicated by arrow:


Step 3) Remove face screws.


Step 4) Replace the capacitors

Flip unit over carefully, giving yourself access to the back of the clock and its capacitors.



Now, my 300SD had two capacitors whereas the 560SEL only had one. Both were 100uF/16 volt capacitors. I had previously ordered a batch of 100uF/25 volt capacitors from Mouser so I was set. Radioshack should carry 100uF/35 volt capacitors as well.

560SEL New:

Step 5) Carefully reassemble the unit.

Be sure to fully seat everything and solder that one point that we de-soldered in order to gain access to the capacitors. After that, put your screws back in and put the pod back into the cluster, and you're done!

Hope this helps some of you out there.

If you've any questions let me know.
