Does anyone have a chart to tell what year a d6 9u is. I’m not seeing one in the service manual. Mine is 9u25348. The engine tag is the same
1957
Hi Mike, yes you can find a useful guide at Erik Christenbury's website, chrisco.com. You can also email him and submit info on your unit so that he can update the list with your machine(s)
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
