Serial number guide?

[D_EDGE]

Thanks diggerdave1958! This was my dads first dozer that he bought 27 years ago that I would love to fix up. The dang thing sat for 20 years without being run and it fired right up last year. Had to use a chainsaw to cut down the trees that were growing up through it!

D_EDGE I would like to see a pic of your D6, and they don't make um like they use too, lol Does she have a pony motor to start the diesel ??
Thanks

 

[D_EDGE]

Yep it has the pony motor. I'll see if I can get a picture of it loaded here.

 

[diggerdave1958]

That is a nice looking 1951 D6 Think about that is a 64 year old machine and still runs, take care of it and it will keep going and going ! And Thanks for posting the pic D_EDGE !!!!!

Hey digger my 690b has no serial number, just a rivit w/ a little corner on it. I bought an oil filter for it and the threads were wrong 12 instead of 16 that they need to be. Found out prior to 588854 SN the threads were 16 which is what I have. Could you tell me whats the last year of that serial number? The guy I bought it from said "oh yeah its an 85' " I pretty sure it can't be! Thanks if you can help

 

[diggerdave1958]

Well Frodomocho1, this is a good one the last year that a JD690B was made was in 1985 and the last SN was 506075 and I can find NO 690's B,C,D or E's that have a SN Higher than 567821? so I am not sure where to go from there I will do some more checking and see what I can find.
Thanks, Diggerdave

Hey guys looking at a cat 312 excavator not sure of the year as there is not an original owner to ask. Here's the serial number 6gk00426. I looked at iron record but I don't have the letters after the 312 like "312b" for example. Any ideas??
Thanks!

 

[diggerdave1958]

Hey, 90plow. I did a little research and this is what I found about your Cat 312 SN 6gk00426 it is a 1994 machine they made SN 00244 thur 00797 and it was made in Japan, Hope this Helps
Thanks, Diggerdave

 

[90plow]

Is that a grey market machine then??
Thanks for the help!

312 Excavator 6GK004276 was built in Japan on 22/02/1994. It was not originally sold in the US therefore that makes it a grey market machine. You shouldn't have any issues getting parts for it in the US though.

Thanks a lot guys! That's why I love this site so much information. I think I'm going to pass as the machine has a gusset welded on the stick and looks a lot more worn than the 4,400 hours the meter shows. If it was a lot cheaper than the 26500 he's asking I would probably take a chance. Thanks again!

Can anyone help me with a year on a Case 580C. Serial # 8979053

Thanks in advance!

 

[diggerdave1958]

Hey, Truck727. Well the best I can come up with is that your 580C is a 1978 machine they made Serial Number 8969420 thur 8980715 so I hope this helps, and let see a pic of the 580C
Thanks, diggerdave

Thanks, diggerdave

Thank You very much diggerdave. I was told late 70's by the seller. I just wanted to confirm. I went ahead and bought it for $6500.

 

[Truck727]

I'm looking at another older machine that the seller does not know the year. It's an Cat D5. Serial # is 96J 1111. Any idea on the year on this one? Here's a picture. They are asking $16,750. Seems reasonable to me but I'm new to buying heavy equipment. I'm just looking for some older cheaper machines to clean up some property I own and have some fun

Date of Manufacture January 1969.

That's a very interesting roll bar. Hard to tell from the picture what shape the undercarriage is in? It's all painted nice but if it needs undercarriage would cost around half the purchase price.
