The 8U/9U series D6 was one of the best Cats ever built. Trouble is finding one that isn't beat to death or just flat worn out. Most pieces still available.
thanks for the help!!!, i am going to look at one this weekend, it looks a little wore out from the pictures, but the price is around 5k, and has been on the farm for over 25 years...might take a chance. anything in particular to check out on this model?

They didn't have many weaknesses. Pony motors are vulnerable, check wear on the bottom of the final drive housings, I've seen them worn clear through. Worn out undercarriage is pretty typical of a farm machine but that's no fault of the tractor. Late units have oil clutch which is a plus and the late units have provision for mounting direct electric start. Transmission cases have been known to crack when units are run in rough conditions without belly pan protection.

Has anyone tried www.ironrecord.com it doesn't seem to be working. I'm trying to figure out the years of a few different cat dozer's.

High horsepower machines generally have the hydraulics mounted to the right side of the operator. Low horsepower machines generally have the hydraulics mounted under the radiator and the pumps driven from the front of the engine crankshaft. You can probably find a high horse engine swapped into a low horse machine but you will also find they will have heating problems as there was barely enough radiator to keep the low horse engines cool in eighty degree weather.
