Each diatribe you wrote points to you not doing a walk-around inspection before AND after operation – that’s just responsible ownership. Tightening nuts and bolts that work loose is part of the fun – get used to it.
Apparently you had never been under the dozer to see that there isn’t a belly pan. Driving through brush and saplings is bound to tear something up if you aren’t careful and know what you’re doing. This all comes from experience.
One thing puzzles me: You said that the left steering clutch and brake linkages were reversed. How was it even possible to operate and steer because the linkages are geometrically timed in a sequence. The clutch is released before the brake is applied. That just won’t work in reverse sequence.
You complain about missing cotter pins?
Your overheating issue, what’s up with that? Radiator plugged? Thermostat removed? Lugging the engine? Bad gauge? Improper coolant?
I’m glad that you have found a good mechanic that can explain and sort things out for you. Remember, “A good mechanic is expensive, a great mechanic is priceless.”
That missing plug you mentioned is for the steering clutch/brake compartment. It’s a straight metric thread. Those are important because they keep debris out of the compartment, and they will also tell you if your final drive or transmission seals are leaking. The last thing you need is oil on your steering clutches and brakes.
Your air cleaner complaint is a valid one. These engines are used in a variety of applications, and the air cleaner included does not fit this application. These are the only pieces of equipment I know of that allow the radiator fan to blow directly into the air cleaner. I installed a Donaldson outside of the engine compartment.
You should have known too, that Nortrac isn’t the only small dozer in town. Mitsubishi BD2, Komatsu D21, Sutter 300, Sweco 480, and the Magnatrac. To name a few.

And therein lies the truth. These little dozers aren’t Cats, so consequently don’t expect them to perform like one. I have been through Cat schools and worked for Cat dealers, and I can easily recognize “operator error” when I see it. So when you are through venting maybe we can address your issues ……. or maybe not.

Well, I’m 76 and have over 750 relatively trouble free operating hours on my dozer.
I self imported from China through a broker, and did all of the assembling and preparation myself.
The only problems I’ve had are the ones that I asked for.
So you dropped 20 large like it’s a lot of money – price out a new Cat D-11.
I think your dozer needs a new owner.

“Oil” and “fluid” are pretty much synonymous when it comes to hydraulics, with fluid being more generic and less specific. After all, ground glass, mud and gravel are also fluid. Use of which term reflects your knowledge base. There are many formulations of hydraulic oil and most will have the AW designation. This is part of the additive package. There are two different base stocks used in formulation – synthetic, with an ashless zinc free package, and standard from paraffinnic base stocks. Most good standard AW hydraulic oils will carry an AGMA rating of 1 to 5. Hydraulic oils are available in viscosities of 10, 32, 46, and 68. (Personally, I use a multi-viscosity hydraulic oil ISO AW 32/46/68.) Many of the oils may be substituted for others in certain cases, others not. Many wives tales and misconceptions revolve around the use and applications of hydraulic oils.

That’s an impressive laundry list of issues, some of which just don’t make sense to me.
Did you purchase the dozer new from Northern Tool in 2015?
“I didn’t want to be a mechanic, just wanted to have a working/reliable dozer.” Sorry to say, but you can’t have one without the other. Small to large excavating companies have their own operators, mechanics, and shops. In my experience, it seems an extreme rarity for an individual operator to NOT be a mechanic. You can go broke quick if you rely on a dealer to repair any little glitch or scratch, or perform standard maintenance.

That’s a design that was made by Donaldson many yeas ago. The same design is also used on air filter pre-cleaners. They were originally called “Donaclone” filters. I have one on my skid steer and dozer, and they are both equipped with an automatic dust ejector “pooter”, which extends the filter life.
The incoming air creates a toroidal (centrifugal force) effect, throwing the heavy dust particles against the housing.

That is indeed a rare engine Adam. Glad you were able to identify it. Hope you get his business.

….. he believes all the parts fit except the sleeves, rings and pistons.
Yes, and he also believed what engine he has. I suggest you call Adam at Keno Tractor and order the correct parts.
