What is a "Washer (SUP)"?

[D.M. Procida]

Could "Washer (SUP)" in a parts list mean that the washer is supposed to be of a certain material, referred to by "SUP"?

I ask because some washers are "Washer (Nylon)".

(SUPplied)

[D.M. Procida]

That's possible. However, I previously discounted that interpretation because only (non-nylon) washers merit the SUP, and many parts are obviously supplied but not "SUP".

Or is "SUPplied" *always* what "SUP" means?

This is from a service manual written in the 1970s.

Here is a choice of things it can mean

This is from a service manual written in the 1970s.

For what?

An Akai tape recorder.

Then I would think 'supplied' an unlikely answer - that would seem more probable for self-assembly items. However, I don't know of any material for which SUP would be an abbreviation or acronym. Perhaps supplementary, to describe one that may not always be present?

Could it simply be the top one? Hence from superior?

Otherwise, Still Unanswered Problem.

[Mike Clarke]

Supplementary ?

[Dave Plowman (News)]

My experience of Akai literature from that period suggests it will be a poor translation.

[D.M. Procida]

I did wonder whether it might be a misreading of "slip" - because there is such a thing as a slip washer.

However, that's inconsistent with the general quality of the rest of the translation, which is pretty good, if somewhat stilted.

B-) Maybe if we had a detailed description of the washer, size, shape, material, function etc refered to by the reference we might stand a better chance. I assume that at least some part of it still exists in the machine being serviced.

========================================= If it's a translation error it could be a 'cup' washer.

[D.M. Procida]

They are washers on a spindle (the reel table assembly).

I *think* that they are stainless steel, though they seem to be almost black, rather than shiny metal.

They are for example:

[outer diameter x inner diameter x thickness, all mm]

6.1 x 10 x .25

6.1 x 10 x .5 6.1 x 10.3 x 1

According to the manual, some of the washers - and it's hard to work out whether these are the ones - can be added or removed to adjust pressure. If these are the ones then SUP=supplementary would make sense.

However, there are also washers called: "Reel Torque Adjust Thrust", and perhaps these are the ones to be added and removed. It's extremely unclear...

[Cicero]

========================================= Possibly something from here perhaps - shim washers:

[John]

Could it be "supplimentary" - as in - not a specific part from a parts list - just a standard generic washer?

[D.M. Procida]

I've posted the list of parts and the exploded diagram at:

Sorry about the quality, it's the best I have.

An "x" after a part ref. no. means it's not shown in the diagram, for example 4-13x is the counterpart of 4-12, but for the other reel (only one is shown).

It's very inconsistent though. For example:

There are two Reel Table Pulleys (one for each reel), but only one is mentioned (4-34).

There are four Reel Table Spring Plates (two for each reel), but only three are listed.

Some washers are nylon, and are listed as such. But some washers are nylon, such as Flywheel Thrust (A), but not listed as such (and again, this one isn't listed for the other reel).

Anyway, don't spend too much time trying to solve the puzzles, but if the list is somehow immediately comprehensible to someone I'd be grateful for any tips on how to work out what is suposed to be what.

Reminds me of a Parts List showing SOT/AOT items. (SOT = Select on test, AOT - adjust on test). So perhaps they mean the assembler should choose the one washer of the three which gives the correct end float or height. SUP =? Set Upon Production?
