This bulldozer is a solid workhorse!

I bought it in 1987 when I started developing my 200 acres of property in the Sequim area.  It had about 5500 hours on it, but the engine had been rebuilt.  The undercarriage was shot.  All six bottom rollers were so bad it would hardly roll downhill.  The turbocharger was weak and the engine, even though rebuilt didn't seem to have enough power.

I found some almost new bottom rollers and had the undercarriage completely rebuilt:

Two of the four top rollers were pretty worn and I replaced them.  The front idlers were good.  The rear sprockets were fairly worn and I later replaced them (see photos further on).  The track pins and bushings were pretty worn and the grousers were very worn, so I replaced the whole set of tracks with a good solid set.

I replaced the exhaust system with a more modern turbocharger that had much more power.

I used the bulldozer to build roads and homesites and put on about 500 more hours on it.  Note the total hours is now about 6000 hours, but much has been rebuilt or replaced with only about 500 hours on the new parts.

I've always kept it stored in my barn out of the weather.  Until today, I hadn't even started it for about three years, but I've kept the batteries (two 12 volt) charged.  It started up immediately after sitting three years!

Now that all my roads are paved, I can't drive the bulldozer around the property any more, so I really have no more use for it now that I'm retired.  I still live on 25 acres, but I have a backhoe and grader that I can get by with, so my "baby" is now for sale.

The only thing "wrong" with the dozer is that the right hydraulic idler pushrod has slow leak in the seal.  Note the sagging right track.  Since it has been sitting three years, if I was going to use it, I would have to pump up the pushrod with a grease gun.  That would push the idler forward and tighten the track.  It's a big job to replace that seal, so it has never been worth the trouble - a shot of grease every year or two is pretty easy!

The blade has hydraulic tilt and it is in excellent condition.  When I bought the bulldozer the bits were quite worn.  I replaced the center bits and added extreme duty corner bits.  You can see that they are still almost new.

Here's the gauge panel:

Here are lots more photos to show the condition of this dozer:

The left track and top rollers are in good shape:

A few years ago I found the left pivot brake was not working correctly.  It was a big job, but I pulled the final drives and found that one of the three pins that the brake clutches slide on had broken.  And the clutches were pretty worn.  I replaced the broken pin and the clutch plates.  Then I replaced the sprockets and final drives on both sides.  The finals worked OK, but the original owner had welded the three pins supporting the planetary gears inside to keep them from leaking.  I never liked those leaks so I replaced the entire drive.  In the photo below you can see the three pins now have no leaks at all.  The sprockets are new.

Also, when I originally replaced the undercarriage, the main bushings, covered by the square cover plate in front of the final drive, were quite worn, as well as the undercarriage guide plates up front.  Those were also completely replaced.

The blade pushbar bracket shown below was also quite worn (it's supposed to be round).  I replaced both sides, so the blade pushbar is now nice and tight with no sloppiness.

The front idlers were in decent shape, but I replaced one of them (I can't remember which).

The crossbar support arm was OK, but the button bushing under the arm was pretty worn so I replaced both of them.

The two left top rollers are somewhat worn, but they still have a lot of life in them:

The right idler is fine, but as mentioned above the seal for the hydraulic pushrod has a slow leak, so every year or so it needs to be pumped up with a shot of grease:

The right sprocket and final drives were replaced a few years ago.  The probably have about 20 hours on them since I replaced them.  The sprockets were brand new.  The final drives were used but in excellent condition:

The right blade pushbar bracket was also replaced:

The right top rollers are like new:

The tracks are in good shape with lots of life left in them:

The hydraulic cylinders that push the blade down are supported at the top by a yoke assembly that rotates in the chassis.  These bushings were quite worn when I bought the bulldozer.  I replaced those bushings on both sides to make the blade push assembly quite solid.

The Carco winch works great.  We pulled a lot of trees with it.

Here are some photos of the cab area:

 The original seat was in pretty sad shape.  I replaced it too, and it's quite comfortable.

The two 12 volt batteries are under the seat.

The 2 speed Powershift transmission works great.  I never had any trouble with it.

A small toolbox on the left of the seat:

The hood area:

Here's the left side of the engine:

All I've had to do here was change the fuel filter (on the left) and the two oil filters (on the right):

To replace the turbocharger with the new style, I had to change out the exhaust manifolds.  The new turbo was like adding a new engine - I was really surprised how much power it added.

I can't recall whether the fuel tank is 60 or 80 gallons, but it's full!

I have the complete Parts and Service manuals for the dozer.  These were extremely handy when I was rebuilding and replacing parts.

 Also the Operator's Manual:

I have a 20000 sq. ft. barn that is great for storing my heavy equipment.  Even though I've had the bulldozer since 1987, it still looks pretty decent and more importantly, it is reliable.

Updated 12/9/17

Both batteries are new.  When recently starting the dozer, I found it wouldn't rev up quickly and it didn't seem to have the pep it should.  After checking the fuel, filters, and strainers, I found the fuel injection pump had some debris in it from a deteriorated flex ring.  So I had the pump completely rebuilt and what an amazing difference!  Not only does it start immediately and idle so smoothly, but it also revs up immediately to it's 2480 spec rpm.  It seems like a new engine in it again!

A good bulldozer! 

After owning this since 1986, I'm pretty much done with this machine on my 200 acres of property.  I've got some smaller machines - a backhoe, excavator, and a grader - that I can by with.  I'll let this guy go for around $20K if anyone is interested.
