350 vs. 350C?
350 vs. 350C?
When I gave the local parts guy my serial number to order some parts he said the machine is a '76 350, not a 350C, even though there is a huge "350C" decal on each side of the fuel tank. I guess the tank could have been changed, or the machine was modified to a C or something ???, it isn't that important to me at this point other than I wonder if there are any important differences that I should know about. I have a 350C technical manual. Should I be getting a JD350 manual instead?
Re: 350 vs. 350C?
Your local parts guy is just wrong.

Stan has a good post on serial numbers there.
If this is a 1976, then it's a C. If it was a 1975, then it could be either a B or a C. It should be easy enough to tell the difference between the two since the C had wet steering clutches and the B had dry.
The last 350-straight was made in 1970.

I think the other major difference between the straight 350/350B and 350C models (other than wet vs. dry steering clutches) is a naturally aspirated engine vs. turbocharged engine. That should be easy to check.

(1) JD Straight 450 crawler dozer with manual outside blade; (2) JD 2010 diesel crawler loaders; (1) JD 2010 diesel dozer with hydraulic 6-way blade; (2) Model 50 backhoe attachments, misc. other construction equipment
Also remember that after the model#on the serial plate the next digit is a C this is for crawler the next one after that is series so if you have a 450CB on your serial number plate then you have a B series 450 machine .If you had a 350 D it would say 350CD on the plate and so on .Recently I looked at a 550A and the owner swore up and down he had a special 550C.Sure enough his serial number started with 550CA There is your sign Buddy!!I shook my head and walked away .Your series is the second digit after model number not the first I don't know why John Deere did this but they did so try that .From one series to the other is a big technical jump you are talking two series wet clutch ,controls are moved and different engine for three things .The other thing is a B and a C are worth bigger bucks than a straight 350 not a whole lot more but they are worth more .Digitup.

350 vs 350C
I don't think any 350 came with a factory turbo, is they did we would have them in our 350C widepads. The turbo comment is correct for the 450's, althougt the late 450B's had turbos as well.
Best to check under the seat.
1. If the steering cluch levers attach directly to the steering cluch cases it is a straight 350.
2. If is has hydraulic assist cylinders between the steering clutch lever and the steering clutch cases is is a 350B, although i have seen some straight 350 with the power assist as well.
3. If the steering cluch levers are connected to a valve bank on top of the rear end (not the clutch cases) it is a 350C or newer.
I always check under the seat as some people put the wrong decals on.[/code]

Hi,
I think they used the 'c' after the model number, then the series letter, as the 'c' was used years earlier to denote anything that was a crawler.
Not that they needed to, as there were no wheel tractors using the same model number as any crawler once they came out with the 350 and 450.
Prior to that, they used the same model number for a wide range of equipment on the machine that required a sub-type designation letter of some sort. As in 420s, 420w, 420c, etc.
Of course this would be useful for phone conversations regarding parts, mostly, as there are some significant parts differences between the sub-types.
I mean, once you get *to* the machine and have a look, it's pretty danged obvious that a 'c' sub-type is a crawler, regardless of the model number!
Anyway, never go by decals since things tend to get re-painted and re-decal-ed all the time.....
Besides, if one were selling an older 350 and wanted to get the most one could for it, a can of paint and some new decals can be a real help, right??
And, should someone give a seller a newer set of number decals, then that's not the seller's fault, right???
I hate it when they paint things before putting them up for sale. I'd rather see reality and then slap paint on myself later. But, then, the selling price might not be quite as high.....
later!

Hi,
Yes, it can be confusing, all right.
My neighbor was in the market for a loader/backhoe. He found a JD350 so equipped not too far away, so I went along to look it over.
It was advertised as a 1989 JD350C. It wasn't. It was a 1967 JD350, which would not have had a sub-letter. What we call a 'straight 350' around here.
The confusion was as follows:
The serial number plate started out 'JD350C', meaning it was an early, straight JD350. That was misread as it always is and so the stickers on the side boxes read out JD350C.
It had the power steering option, which made it look like it was newer than it was.
It also had a completely re-done undercarriage. New chains and pads, new rollers and idlers, new sprockets. The whole smash. That made the machine look to be a lot newer than it was.
The engine had been overhauled, as it ran strong with no sign of smoke or blow-by. The hour meter showed 11,000 hours, so if it were original it would have shown it.
The machine had a newer coat of paint on it, so it looked real good just sitting there.
The age giveaways were there, too.
Firstly, dry steering clutches with optional add-on style power steering.
Secondly, an original first-run style of injector pump.
Thirdly, the serial number plate which showed it to be a late 67 build.
I don't blame the guy selling it. He bought it this way and as a 89 machine. I think what it was, is that 1989 was the year the machine had been overhauled. I bet it was all done at the same time by the guy *he* bought it from and so that year was spoken of and then misunderstood to be the build year.
I have to say that the seller was unhappy with someone else when I pointed out that it was a 1967 and had a list of serial numbers by production year with me.
In the end, my neighbor was a little overwhelmed by the crawler part of the machine and opted to buy a JD300 tractor/loader/backhoe that wasn't overhauled but had only 3000 hours on the clock. It was bought new by another farmer in the local area and so not used in the manner that a commercial machine would have been. I've never seen a loader/backhoe that old with this little wear on it before. Amazing.
Good luck with your dealing on yours!
Later!

ok,boys -- i think i finally have it. i now firmly believe it is a 1967 straight 350. yay.serial number is right. steering system is right. injector pump is right. engine/cooling systems are right.
it came to me with a 350b tech manual, a 350c op manual, and a new straight 350 parts cat., = pc-921.
wish i had figured this out a few days ago, before i ordered a brand new deerely 350c shop manual.
tante grazie.
