Our dozer.  And the one we almost bought first, pretty glad we didn't. And #1 operator.

What a great pic, is that your son?

I got this last Halloween of my grand son on his first red machine.

Dad has been operating dozers almost solely since 77 or 78 when he got of the Navy. He has built alot of feet of terraces and waterways and a bunch of ponds and lakes. His Dad ran dozers as well until his death. 

The guys my Dad worked for for years ran three D6C's and a D8H. Early on they had some old D7 cable dozers. He worked for them until they got out of it. The last 6 or 7  years he has been working for a guy with later model equipment. They run two D6T's and two D6R's. They broke their record last year for the feet of terraces they had done in a year. I want to say it was 90,000 feet. I think they did something like 15'000 feet of waterways. Also built one good size lake and some ponds.

I wish I could find pictures of Dad on the old D6C's. I know there is one when they had all the D6C's and the D8 on one job. Sometime I'll have to try and round up some of the old pictures we have.

D8K I'm overhauling the engine in. Started last year about this time but they had a truck go down and money went that way. Just started back on it last week.

excuse me for my stupidity, but what is the difference/need for the tall triangle shaped tracks vs the straight oval type ? I bet that D8 is heavy - how big of an engine do those have?

Hey sledge how is that knife looking?

 

You’ve seen all there is to see so far. Been busy with life lately, extra shifts at work, and some other projects.  The little guy (almost 4) wanted to work on his small engine tonight when I got home (taking apart a tiller engine to teach him the parts) so that’s what I worked on. Knife will be there and I will show more progress when it happens ?

How well does it preheat the Diesel engine in cold weather?

How long does it have to “wirl” at 0 degrees or colder to warm the Diesel?  I do not see a water jacket on the electric wirler thingamajig.......

When they are converted to 24 volt direct electric start the precombustion chambers are changed to add glow plugs.  Then like a 560 diesel, preheat and crank.

My 7E starts pretty good in the cold with good glow plugs and batteries.  If I’m working it every day it starts easy down to 0°F. Coldest was probably when it was -30 overnight and had warmed up to around 32°f that afternoon.  Glow plugs on for 2 minutes and it fired up within the first couple revolutions.  Everything was still white with frost. 
 

I like pup motors for the noise they make and the novelty but I’m glad mines direct start.

Doesn't look a good place for a driver who needs a "senior's siesta"

The way I heard it 

"Why does it cost about as much to overhaul the pilot motor as it does the main engine?"

And around pilot motors

A couple of friends took a punt (uninspected) on a couple of old D7's from a long way away.  One bloke's answer to questions of risk was "Fortune favours the bold".

They took some pilot parts for inspection by another friend who ran the local council machinery depot.  He announced that the parts were "f***ed".  

One of the owners reply was "You're used to working on a budget where you can do that.  We're just a couple of broken down ranchers and we need to know if there is any way we can get them from "f***ed to half-f***ed"

Which term entered the local vernacular.
