    Default Cat d4400 power unit

    I recently purchased a Link Belt drag line with a D4400 power unit serial number 1s4402. Any idea of year of manufacture?


    Thanks, Matt

    Default D4400

    According to the Cat SNID book they went in production in 1936 so it would be a little newer than that but my book only has start up years but some on here has a book with each year a SN was made.

    What book would I need to get that lists individual years of manufacture?

    Try an early version of the "Caterpillar Performance Handbook"

    I seem to have lost track of mine

    The one I had (can't find) was a 1972 edition but I would think any of the 70's versions would have the info.
