How to tell series ll

I can't find my serial number reference but surely somebody will give you the breaks for the various series. Beside that if you can detect the original paint it would have been the more red type orange with cream wheels. Another series 2 only feature was stamped metal nameplates on the hood instead of decals. Another thing is the grill will be the later type used from series 2 to 4.
There are a slew of series 1 D17s around with updated paint schemes and whatever decals the painter placed on it thus the only real teller is the serial number.
 
(quoted from post at 21:44:59 11/01/20) On a D-17 how can I tell if it's a series ll
if I can't see a decal?

Can't remember where I got this from........might have been on this site even. I printed it out when I got my D-17 (Series II).
The Ser. # on mine is: D-17-34633.

Thanks, he said it's a series ll but it is
all orange and has the oval d-17 below gas
tank so I'm pretty convinced its a series l.
What are all the disadvantages of a series l
vs ll?
 
If it's earlier than serial number 23000 or so, it's got the WD engine with low pressure bypass filtration. The last of the series 1 got the G226 with full flow oiling. No differences otherwise.

Aaron I assume by your statement you meant to say "...it got the WD engine STYLE low pressure bypass filtration." Every D17 had the G226 engine with larger journals and the center thrust bearing. No W226 engines were used in D17's.

That picture of the chart is also wrong in that all Series I and II did not have power steering pump driven off the back of the generator. I'm not sure of the SN break but somewhere along the way it changed to being driven off the back of the governor housing (between the governor & distributor) before it moved to left side belt driven in Series III. I have a very late Series II parts tractor that has the governor driven power steering pump, hood panels w/o the metal name tags and the updated wide front end wishbone (that was effective SN 38136).

The chart says number #19978 which may be the "engine" number rather than the tractor number.
The parts manual (like Aaron), says the full flow system started with tractor #24001.
I had a friend who owned a D-17 Tractor Ser. #21657 that had the full flow oil system...Don't know if the engine was swapped but I don't think so.
Easy to spot because the filter is like your typical FL-1A Ford filter.
One of the biggest improvements A-C ever made.
As Skyhigh points out, there appears to be some errors in that chart. I don't think any D-17 had the PS powered off the back of the generator. Up until tractor #42001 (Series III) the PS was powered by a pump between the governor and distributer drive. And, of course, all D-17s had the new block with larger journals as well as higher compression pistons which "jacked up" the HP beyond the WD-45.

jhncp, could you please post your "tractor" and "engine" serial numbers and whether or not you have the full flow oil system? It would be interesting.
 
It is a 1957-58 or early 1959. Serial number is on the left side stamped on the bellhousing near the air cleaner oil cup. Power steering was always an option, even on a series 4. She's been repainted and has wrong decals on the hood for the age I think it is.
 
I was thinking it was a really good deal for
$2500 but now not so sure since he said it
was a series 2. And no power steering.
Claims to only have about 1000 hrs. Are
there other disadvantages as far a
hydraulics etc?

Only 1,000 hrs on the tractor ??? Really ?? on a 60+ yr old tractor ?? No way !!! Maybe 1,000 hrs since it was last overhauled ?? But, I'll be the hr meter doesn't work or it may not even have an hr meter as that was an option too. If the tires are all really good and the rear rims aren't rusty rotten from fluid, that is a good start. Operate the tractor for at least 20 minutes at full speed and see if the exhaust smokes blue or smells like it is burning oil. This is always a concern. They won't smoke blue when cold but after they are warmed up and hot then you figure out it needs an engine overhaul. Normally one that age is a $1500 tractor around here with no power steering.
 
The tach only shows 850 but who knows when
it quit working. I guess when they took
motor apart they said it was in good shape.
I wonder if the 9932 is serial number. Also
where do I find engine serial number?

I would guess 9932 is the serial number, making it a 1958 model. Two things for sure: #1. It has a new foot clutch. #2. It has new brake linings, not liner. Did you read the rest of the repair information ???? That engine has been sitting around outside and had water in the cylinders and a stuck valve !!! It could now have a bent connecting rod from anyone trying to start it with water in the cylinders !! You had better run it a lot before buying, because that engine is somewhat suspect.
 
I'm with the Dr. That engine needs some time on a dyno and a compression test to make sure it's healthy. Realistically, it's not worth much more than the repair bill.

Could that number printed on the upper LH side of the invoice be the Ser. number? D-17 3806 That would make it a '57.
 
D-17 serial numbers began at 1001. From the introduction in the Fall of 1957, the serial numbers went from 1001 to 4299. The official s/n list shows the first tractor for 1958 was s/n 4300. So, anything prior to that was built in 57 and are 57 model year builds even tho it was just for 3 or 4 months. The full flow oiling system began at chassis s/n 24001 which was late 1959. The gas engine serial number was only 19,998 because their was 4 to 5,000 or so diesels built in this time frame. Both D-17 gas and diesel were Nebraska Tested in November of 1957. The gas chassis was s/n 1128 and the engine s/n was 17-1071-M making it the 71st gas engine built. The diesel chassis actually was 1001-D, so it was thee first production serial number chassis built. The diesel chassis had a "D" stamped with the serial number because the torque tube clutch shaft was 1 3/8" shorter than a gas clutch shaft, so they had to keep from mixing them up. Other that the clutch shaft length, the chassis were identical between gas and diesel. Diesel engine s/n was 100274, which to me meant it was the 274th diesel engine the Harvey Engine division had built, starting at 100001 ??? That's a guess on my part.
 
You lost me Doc.....so, could D-17 3806 be the serial number?
The number is on the invoice....must mean something?
Hopefully, jhncp will get a chance to look at the actual serial number and post it here shortly. The engine serial number (behind the Carburetor) would be nice to know as well.
 
I was thinking the 9932 might be serial
number too, too bad pic wasn't a hair
higher. I was thinking of offering 2000 but
that isn't much higher than repair bill. I
think the motor is low hour original but got
rain down exhaust , and repaired by
professional shop so most likely ok.
 
Absolutely 3806 could be a legit D-17 serial number. They started at 1001 and from there to 4299 were 1957 models.
 
He did say the invoice 3806 is the serial
number. I assume tractor serial but not
sure. I decided not to look at it for now.i
still think it is a pretty good deal if the
tires look as good in person as pics and the
tractor looks clean and tight and if there's
extra factory draw bar parts.
 
At this point in time what difference does it make which series? Isn't it a matter of what shape it's in and how good the tires are?
 
The tractor pictured has a series I grill and series II side decal. A real series II has a silver grill with black bands across like wide stripes and a few other changes.
