Vintage Synth Repair

Wrong old son!  ALL clocks are oiled with special clock oil, similarly
watches are also oiled with special watch oil.  You never ever run a clock
dry it will ruin the pivot and the bush.

Hello:I've used this only on Hammond preset keys and not on key contacts and
I've used it for 30 years without any problems,if you take the preset keys
section apart the contacts are sealed up so the WD-40 does not get on
them,The purpose that WD-40 was made for is to mix with other lubricants to
thin them down,Hammond uses grease on the preset mechanism that dries out
and turns to a very sticky paste,any contact cleaner would completely remove
the lubricant and cause the presets to lock up,I would never use WD-40 on
anything else,but this is a mechanical problem on metal to metal parts not
an electrical problem.I work on a dozen Hammonds a month mostly in Churchs
and I don't get callbacks but do get return business from my customers for
other problems not related to my repairs,for electrical contact problems I
use Caig De-oxit which is recommended by most manufacturers tech
departments.I understand not using WD on clocks,most clocks are designed to
have dry contact and not have lubricant which can cause the parts to stick
together.

Without doubt one of the worst things to do with any keyboard is to use WD40
on it.  It is intended to be used on motor vehicles, around the ignition for
instance.  You can do untold damage with WD40 - we see this with clocks
regularly and when one comes in for repair we double the service charge.
 
Recently I had a church organ to repair where the transpose keys and the
preset tone keys had jammed up all due to the use of WD40 in the past.
 
So having said this, what should you use?  The answer is simple use
something designed to be used on electronic equipment, Electrolube, also
known as contact cleaner.  I don't know what the name is in the USA but I'm
sure you have similar products.

I see this problem with a lot of Hammonds and I usually try to cure it
without taking anything apart,the grease on the mechanism gets thick with
age and keeps the bars under the keys from moving,the way I fix it is by
squirting WD-40 beside the keys and pushing them up and down,use the little
hose that comes with the WD-40 so you can shoot it all around the keys,the
sticking mechanism is in the frontal part of the key,the WD-40 mixes with
the grease and loosens it up,once you get the lock down bar to move go back
and forth between the cancel key and the various preset keys,the volume
should also return by rapidly moving the keys up and down because it usually
is caused by dirty key contacts and the movement will clean the
contacts,I've been fixing Hammonds this way for 30 years.only after trying
this do I rarely have to get under the keys,if you have to get under them it
is a bit of a project but only takes about an hour.
