Vic, my serial number has no alpha, simply 361400042. I took this off the tag on the front section of the frame and it is lable serial number. What does that tell you? I'm thinking this is like Scott says this tractor is not was not as new as I thought when I bought it. Probably a left over and they knew a fool when I walked in. Can't complain though, Haven't had all that many problems with it and it does what I need it to do.

I think the older models Mfg. year began with a #. The first # should be the year it was built. A 2003 model.

Speedy reply..wasn't expecting that. I think what your saying is mine is probably an 03 model. My wife says she thinks I got it in late 04 or early 05 so I guess that's not so bad. let me ask one more question. when I bought it it showed maybe two or three hours and came with front loader and backhoe. At 19 thousand was that a rip even if it was a hold over?

Doesn't sound like a bad price.
What backhoe did you get.
My 2001 DK 35 model # begins with a 1. I believe yours is a 2003.

Diesel 101. In most Diesel engines there is no restriction in the air going into the intake manifold (no choke and no throttle). In other words, the cylinders always get a full load of air. Power is controlled by regulating the amount of atomized fuel sprayed into the cylinders so the engine runs "lean" (extra air) at all but the highest power settings. To accomplish this, the fuel injection pump pumps a small metered amount of fuel to each injector and the injectors don't "pop" open until the fuel pressure reaches a predetermined value, typically above 2000 psi. The injection pump has a separate pumping piston for each engine cylinder and these are controlled by a "rack" that moves linearly to increase or decrease fuel to all of the engine's cylinders, simultaneously. The rack is controlled by the hand or foot "throttle" and a centrifugal governor so, in effect, your throttle position produces a fixed RPM so the injection pump increases or decreases the injected fuel quantity to maintain that RPM. Now, the final wrinkle is the fuel shutoff; the rack is moved to the full off position (zero fuel injected) by either the solenoid or the manual fuel shutoff lever. There is no provision to stop the engine by shutting off the air although people have done this manually (like a rubber bag over the air cleaner) to stop run-away engines.

All of the preceding applies to conventional mechanical injection systems. The new high-pressure electronic systems are different.

But there were engines that did have a mechanical air shut off for emergencies. Can't remember what engine but remember it was a simple butterfly stop on the intake tube and when you pull the cable it would trigger the stop. You then had to manually reset it. But it wasn't on a tractor either.

Some of the old Detroit diesels had that setup.

I think it was an old motor grader I was running. 4-71. Does that sound right? It heck to get forgetful.

Could be.
I had it in a few 318 and 350 V8 Detroits I ran in Tri axle dump trucks years ago.

It's a BK1550. Powerfull enough for digging water trenches, things like that. Doesn't have a tremendous reach, probably about 9 ft. but does okay for what I do.
