Can someone help me identify year 450
I believe Ijust purchased a 65 - 70 straight 450. Can someone help me identify the exact year. It’s serial number on the dash tag is only 3 numbers and they are 297 with a model number of 7450.
Re: Can someone help me identify year 450
aint positive, but i think the 450s serial numbers are on seat base next to your right leg.
try search serial number ovation in this lte model forum...or someone with more positive location will soon advise...dont believe serial on dash
Edit...one post indicates that if possibly 450b...the tag should be on the battery box and that would place that one near midway in the series..for close date
also helpful to add your location to your profile

Wrong tag, that is the loader's serial number tag. 7450 is the model number of the loader on your crawler, not the crawler. A straight 450 crawler serial number tag will be on the panel under the seat, right behind your right calf when sitting in the seat. If it is not there look for two 1/8" holes about 3 inches apart horizontally. That is where the tag was. Mid-way through the 450B production the tag was moved to the front panel of the battery box, where you would see it getting on the left side. If it has the two holes there you don't have a 450, it would be a B series or later.

Ok guys I finally got around to adding the serial tag under the seat. Here it is SNT5E3M011153T
Re: Can someone help me identify year 450
Here is the machine serial number tag breakdown using the 450 Introduction from the JD 450 Parts Catalog:
SN = serial number
T = Tractor
5 = JD450
E= Crawler - Loader
3 = Diesel
M= (Transmission) Hi-Lo-Reverse
Serial number: 011153 (This number falls in the 1965 build range using the serial number list on this site’s FAQ board)
T= (Build location) John Deere Dubuque Works
This serial number indicates it is a 1965 straight 450 crawler tractor equipped with loader having a diesel engine and H-L-R transmission.

I had assumed it was a 65 - 70. Thank you, Jim B. With exception of turbo on later models. Do you know for approximately how long the 450 engine remained exactly the same after 1965 ?
Re: Can someone help me identify year 450
I don't know the number of years. The basic 4219 engine remained the same for years and was used in many wheel tractors and other equipment. Changes like injectors, injection pumps, turbos, and timing gained some power. Accessories like the power steering pump addition on the early 450s and Bs were added to fit the application the engine was used in. Are you looking for something specific?

Re: Can someone help me identify year 450
No, I was just wondering when and if the time comes to buy engine parts if those parts apply to most 450’s. I’m finding it’s not very easy to track down parts for these older machines. I’m wondering for example if I were to ever need a head gasket. If a head gasket or water pump is the same on all 450’s ?
