Re: Explination of Type Codes per SM 2064

Post by shullpeter » Mon Dec 17, 2012 10:54 am

I have read the explination of Type Codes and am still a little confused.
I have a JD 450BA
SN# 132787T

Does this mean I have a 1972 model? what do the B and A stand for?

Engine:
4219CT02
198851T

Is this a Turbo or not.
Last where can I get a repair manual for this?
Thanks in advance for any help
Peter
Oh I just bought this machine to use for clearing roads for logging and new to heavy equip.

Welcome to the board.

You have a 450B, manufactured in 1971. The B is the "version", so a 450B. The "A" is a designator for the type of crawler, but I am not exactly sure what. It could be standard versus wide track or something else that someone else will have to answer for you- I don't have the manual.

As previously mentioned in this thread, the 4219 engines for the 450B did not come from the factory as a turbo, but could be ordered as a dealer add on. Thus your machine may or may not have a turbo- can you look and see if it has the turbo? It should be mounted off of the exhaust manifold similar to this photo i grabbed off the internet:

There are a number of threads about ordering service (technical) manuals for a 450B- here is one of them:

European serial numbers JD 450 different from the US?

Post by Jeroen » Sun Mar 24, 2013 12:23 am

Hello,

Do you know if European serial numbers differ from the machines for the US market? Mine a 450 dozer has the serial number 450 AC 193731 L I Made in Mannheim Germany, I can't find this in your list, unless it's a 'B" they called "AC" in Europe?

Thanks for your help, Jeroen

Hi Jeroen-

Read these threads, as we have had a few of these European 450A's discussed on this board and those other owners did indicate the serial number ranges are different:

European serial numbers......

Post by Jeroen » Sun Mar 24, 2013 1:58 pm

Thanks to refer me to this message..... but I still have no clue on how to identify My JD 450 AC, Strange that with the amount of units that have got a different serial number than the ones for the US market, no one has done a cross reference investigation, or asked JD about this. I did sent them an email in Mannheim ( Germany) to shine some light on the matter. If I ever do get a clear answer, I will keep the forum informed..... If someone else knows...... I can't wait to know, don't want to use my recently purchased 450 until I get a manual that tells me what to grease and which oil and filter to replace with what specification. I F***ckd up heavy equipment before by low or no oil levels etc.

JD450C non turbo

Post by Dave D » Fri Feb 12, 2016 5:18 pm

s/n 450CC-203454T engine 4219DT 02 301525T
On a tractor this old, could be a drop in engine? Definitely no turbo. Rubber hose from under dash air box to intake. Not an overly loud tractor but it does not have any muffler.

Riddle me this. What is a:. Type E7450,. Serial No. 0089xxT. It does not follow the format in the decoder. It has JD450 stenciled on the side. The tag is on the right side of the instrument panel attached with rivets and looks original.

Hi,

Beats me. The serial number list ends long ago, and the decoder isn't known to go further. May be a machine newer than when the list ends. Plus, the decoder is only for Dubuque, Iowa made machines. We've seen plenty of different serial strings from other plants.
