Hey Guys, new to the forum. Been googling around recently and stumbled upon your forum and read a bunch of good stuff so i figured i'd join up and ask my question directly.

I own a small excavating company. I'd like to get myself a smaller dozer. I've been looking around for a good D3 or a D4. Figure it'll be a good size for what i do. There's a D6 for sale as well for around the same price but i think that's too big and too much of a pain to move.

Anyways, i found one on facebook. Guy is asking $6k. I don't know anything about these. It's an older one. I think 70s but that's a complete guess. I'm going to go look at it this weekend. Is there anything i should be looking for in particular? Also any ideas on weight of this machine? Google says 18k but this thing looks a bit heavier than that.

Really just wondering if this would be a good first dozer for me or if i should keep looking around and buy something different.

I know these pictures aren't great but it's all he has at the moment.

Thank you!

Thank you!

I'm pretty knowledgeable on what to look for myself just not specifically on this dozer. Like i know those track pads are probably like 35% life left but they're not wearing the bolt heads yet so they should still have life in them considering i think i'll only be using this thing for 50-70 hours a year if that. I also know to check the sprockets for wear, check all the rollers, idlers, check to see if the pins have been turned, see how far out the track adjuster is to see if the tracks are stretched, etc.

I also know that if possible i want to put this thing against a tree and see if the transmission stalls out or if the tracks just keep spinning even if the machine cant physically move forward.

I'll also use the hand clutches to make sure they engage properly.

Then just a good look-over of the machine, check the oil and smell it for diesel, check coolant and see if theres coolant in it as well as possibly oil in it, etc etc.

I just figured that someone on here might know that this is a XYZ machine and on XYZ machine this or that is a known problem and blah blah blah or watch out for this or that on this.

I"m excited but obviously i'll keep my poker face on when looking at it.

I have an International 175C crawler loader that i love playing around on so i can't wait to have a dozer.

It looks like a D4D. The early ones had some problems, I don't know the serial no break. For the asking price it should be running. It looks like it has been there for years, maybe parked for a reason. Might be one of those scrap price deals.

the serail number is very important for parts---the older Cats had the serial number in two places, the upper left side on the rear steering clutch case, and on the engine block above/behind the pony controls. these were tags riveted on
someone will come along if the location is somewhere else

I find my power shift and pedal steer machines so much easier to run than the old manual ones , and love my D3B with the 6 way blade--so easy to grade with

Check the bushings on the track rails, sprockets and bottom rollers, thats where the big expence will be if needed and the amount of work you'll get out of it.

Had a owner of a D4 D that had been around a lot of equipment that the D4D models fix the final drive at the first sign of a oil leak, much cheaper.



On my older 9u D6 that just means there is oil in it.


Good luck

On the d4d it is very easy to pop off the rear inspection covers 4 bolts each side for the break/clutch pack compartment inspect brake linings and MAKE SURE that the compartment is dry make sure that bevel gear oil isnt leaking in and make sure water/moisture hasnt built up in there from setting outside. They are little monsters it is amazing how much work you can do with those little dozers i had a d4d 22c powershift with tilt and loved it the only thing it was missing is a 6 way blade other than that very fuel effecient great running dozer. Good luck and 14k-18k depending how they were dressed out i hauled mine with a 3/4 ton pick up not making it wrong or right

Hey neighbor, welcome to the forum. I've seen that old girl on marketplace too and thought about taking a ride to check it out but I got too many irons in the fire this year.

Let me ask, what kind of excavating work are you doing? Keep in mind this has a straight blade. Any old Cat with a straight blade is gonna be a good pushing machine so long as everything works, but there's a reason smaller dozers are now all 6 way blades. If you're doing a lot of topsoil stripping or small clearing jobs this would do pretty well. I've used my friend's D4C for the same and it works great.

If you go the 6 way route you can pick up a good older one like a D3B or C, Deere 350/450, Case 450 etc. for not much more money. I know a guy in Manchester who's refurbing a Deere 350 6 way and will have it for sale in the spring for around $10k if that's something you'd like to try.

"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."
