Having worked at a rental store and playing a bit with power generation my personal observations are people still think "old school" with engines. These Tier 4 engines NEED to have the **** worked out of them. Running at 30% engine load is just ruining the equipment. Why do you think the days of big bore, 16L on-highway truck engines are over? Because its too much engine for a measly 80k lb rig. I've lost count of how many times I'd go to a generator for emission codes and come to find out they're running the engine at a 20% load? When you explain to them that they created this problem by renting a generator that was vastly oversized for the job I'd get the deer in headlights look.
You nailed it.So I'm going to ask a question that I've asked before, and haven't gotten a good answer for. What are we supposed to do with tier 4 cranes? Take a single engine truck crane/ or boom truck, it has to be big enough engine, to move a 90,000lbs rig down the road, so the customers/ company sells/ installs a 500hp engine. Then when we get to the job site, it has to sit and idle 1/2 the day, and "working hard" only turns a set of hydraulic pumps that you could pull with a 80 hp engine. There is no effective way to "run it hard".
All my trucks and cranes are pre 2002. I don't own anything new enough to have def. A old 6-71 I have will just burn a little blue for the first 3-4 miles after its been on a jobsite for a week, burning out the slobber from the exhaust manifold. Somehow I don't think that kind of use is going to work with def equipment. I have had a little experience with regen, and that engine in that particular crane was a nightmare. The company that owned it gave up on it last month and sold it.
Keep everything pre 2002 until I absolutely have to?
I have no knowledge on military spec. Do they run Tier4?
I just can't imagine trying to run some kind of maneuver and having an issue.
The military does not run tier 4. They know it doesn't work. In some applications, they still run brand new 2-cycle detroit engines as they have a standing contract with detroit till like 2040. The best thing to do in a application like this is run pre-emissions stuff if you are paranoid about deleting something.You nailed it.
And it is a problem.
Friend of mine works in a local truck shop.
Our city fire trucks are always in the shop. ALWAYS.
He thinks, and I have to agree with him, that there should be exemptions for certain applications.

I don't think its a good idea to be pulling off emissions equipment on a nationally televised tv show...…...….where government officials could be watching. LOL
Hello People
Just sat watching gold rush the other night and noticed the guys were having problems with the dpf throwing codes and shutting down the engine (Cat C9) on a large water pump.
After much messing around with the machine the mechanic decided to remove the full DPF/egr system he took off the NRS cooler and blanked everything off. What amazed me was he got her up and running no problem.
Is this really possible or just TV bs I have a few machines with the C9 with DPF not ad blue and would love to rip it all off, I'd like to hear other peoples thoughts on this.
Cheers
