number on td15

[jared phillip]

hello. i have a td15b dozer. the serial tag is gone and i am trying to figure out what year it is and engine. i know its a 407 or 361. I found a number on the side of the left side of the block under the intake. it is #TD15B PM 7514, does this help identify any thing, thanks

Walk up to the rer of the dozer and act like you are trying to put a big hug on it. Right where your right fingers hit, written verticaly in the rear housing will be in numbers which are your serial numbers. Prety much all the 361 dozer engines had the turbo mounted out funny on a 3 bolt metal pad ,larger unit siting crosways to the engine. The Normal 407 mount is a smaller turbo mounted directly to the exaust manifold.
Also about time they went to the 407 their was a change in the front cap. Call the early b a square noze then they rounded it off when the 407 engine was used

JM, will the numbers be on the back of the dozer or side ( by the final drive). I sanded all the paint off the right side ( area above and behind the right final drive)and could not find any numbers. is this the right area? thanks

Right side of the square houshing that the final drive mounts to. Would be written or stamped in one inch numbers verticaly right at the rear edge...Now I have found very early units that did not have this very few but some. That being the case it will be a very early td15b. When you look ate the housing that the radiator sits in.
Dose it look like two peices off metal , sides and a top welded on it, or does it look like it was formed ,pressed, one peice curved. That change came about at something around 26,000 sn number. Tight under your left aarem rest on the outside of the seat was also a factory tag but they always got lost, burned or swaped around.
I suspect that engine number you came up with is going to be your unit serial number///

Don,t have my sn # book right here it is in the shop but found your photos. Just as I suspected
early square noze tractor BUT does have later styled front idlers. Close to a i963 but I will
get you a definate answer, theat 7514 is a good sn number for that vintage.
