He broke this down for me a while back when I had questions about a manual. Also if you contact Hobart tech support they might be able to assist.
Person I got with was helpful. Her email is:
-
I believe it’s 23 Jan 1985 if my memory is correct. Year and Julian date.
-
I don’t think the manufactured date is a part of the serial number and he’d need to contact Hobart for that info.
Hobart was still making the original C-Line machines in 1985 (the ones with the control boxes mounted down on the sides of the machine below the tray tables). His question is about a C-Line-A machine (single control box up top of the machine – with rocker switches), which was their next generation of conveyor machines.

Shawn, just so you know. What I had broken down for @nafets47 was how to decipher the MODEL number. Hobart made things confusing in that regard. This might be spelled out in their spec sheet, but I’m presently not inclined to read all twelve pages of it. Here’s THAT:
CRS66A Dishwasher Specifications
The model number of your machine actually denotes sections covered by TWO separate parts manuals.
The C (conveyor) and the A in the model number means it’s a C-Line A series machine. I think they started making that series around 2000 (or earlier), then retired the line for the completely redesigned CLe series machine about 2011.
ANYWAY…
The RS in your model means it has an optional section called a recirculating scrapper (RS), which measures 22″. Hobart ALSO made an optional pre-wash section (so, PW in the model number) that was 36″. That’s NOT what you have. So, you have the 22″ one. Here’s the parts manual for the RS section:
CATALOG OF REPLACEMENT PARTS – MODEL RS22A & AW SERIES PREWASH UNIT
FINALLY, there’s the actual DISHWASHER section. That’s the section with a WASH tank, a RINSE tank and a FINAL RINSE. Your dishwasher section is actually a C44A machine (I know. Confusing…right?). Here’s the parts manual on THAT:
CATALOG OF REPLACEMENT PARTS – C44A, C44AW, & C54A SERIES DISHWASHERS
In mid-production – Hobart made some major changes to the C-Line A series and published a supplemental parts manual to cover those changes. Although it doesn’t apply to the machine you asked about, maybe you have a newer C-Line A in your school system which it might apply to. Here’s THAT:
CATALOG OF REPLACEMENT PARTS – C-LINE A/AW DISHWASHER SUPPLEMENT
FWIW: The two preceding manuals (for the actual SECTIONS) both show they were revised in 2018 (vice 2016 for that supplemental manual), so might actually include parts relevant to the C-Line A series’ later incarnation. HOWEVER, those revisions both merely (and ambiguously) refer to the machine differences in design as PREVIOUS CONSTRUCTION and CURRENT CONSTRUCTION. In other words, the 1st generation (older) and the 2nd generation (newer) renditions.
LASTLY…your model number…by the NUMBERS. We already covered the LETTERS.
As you’d said, it’s a CRS66A. The 66 means the whole thing is 66″ long. Since it’s a C44A with a PS22A section, then 44+22=66.

Damn. Is that why they pay you the big bucks?

LOL! Well then, I want to see that bank account that nobody told me I had.

Thank you for the information, the effort is appreciated.

The “C” line machines have been around for a long time. They have many generations and Mod’s. Make sure you have the all important “ML” number with all Hobart. They have been bought and sold many times over the years. Presently they are part of ITW. (Illinois Tool Works) The one thing I remember from way back is how they protected there repair info and screwed there techs. At one time they had there fingers in all kinds of food service equipment. And their mainstay was always Grinders and mixers before branching out to Meat saw’s, scales, wash machines, ovens, reach in coolers, and several specialty items. All for the quest to be the king. But there limited support to outside service, and high repair rates caused a backlash from buyers/users. .

I stumbled across a TSB today that was included as part of a service manual I got from their Hobart Service Manuals link.
This TSB explains how to determine your Hobart equipment’s date of manufacture. So long as there’s a two or three letter date code in the CODE or MD block of the machine’s data plate, you can narrow it down to month and year.

Hmm. Now that I want to attach it, I can’t find an icon in this reply block to do so.
I’ll post this anyway and then look around…

This platform gets LESS user-friendly everytime I log on.
So, I had to go into my profile, upload the document, then copy the link. Hopefully this is it:

It definitely is constantly changing. I haven’t seen a notification by E-mail for months now.

Hey y’all’s I didn’t know where else to turn and this seems to be the best spot for getting some help on figuring out how old this C-44 is (that’s right, not a C-44A or anything like that)
The serial number is 12-055-944. One lady claims it’s been around since before 1965.
Thanks!

I have no clue. But @ectofix might be able to tell you.
Or you can shoot Rebecca.Eichhorn@itwfeg.com an email and she might be able to tell you.

ectofix posted a link to dating equipment earlier in this thread. If I understood it correctly it could be 1988 or 1981
