Vintage Synth Repair

Tim 
I know you caught a lot of grief over the WD 40 on the bar for the 
preset keys but after I saw Bob samorkate photos I knew I could try 
it with little concern. For the record it worked great.

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.

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.

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.Regards Tim K.
