New to us, trash compactor. After we received it, it was parked for a couple of months. Tried to start it this week and  it would not run more than 20 seconds (protection system). Couple of hours reading operating and service manuals, did some basic checks and finally found a corroded plug on the coolant level sensor. Now I have to go through the whole darn thing before releasing it to the public works dept. Did I mentioned that this is an hydraulic nightmare to work on ? LOL

Just to give you an idea of the size of this thing, the inner circle of the steel wheels is about 5.5 feet and overall height is 12.5 feet at the roof line. the filtration system on top is another foot. It weights a little over 34 tons (from the scale documents).

Are you going to change all of the fluids?

I don't think your new Micropod is gonna work on that thing.  ;D

wow that is going to be a heavy job.....was bad enough on my John Deere

Sending oil samples for analysis first (hydraulics) since it would mean dumping 350 liters of oil. I'm taking out all of the hydraulic filters and cutting them out for inspection. Rest of fluids are getting changed as well as the diesel in the fuel tank.

Yes, that is the reason I asked, changing the fluids will be a very expensive operation.

Spence,

I have a John Deere tractor...had an issue with a hydraulic pipe and had to replace the hydraulic fluid.

I was an expensive exercise, expensive fluid and a lot of it.

The hydraulic fluid is shared with the entire transmission.

That machine will have much more than my JD, glad I'm not paying for it.

(by the way Spence the JD is up in the hills, I'm very familiar with the road up there)  ;D

Denis,
I think a few of us might be interested in any questions you have......I'm very interested.

Denis, is it one of these if so which model?

Would love to drive it. Sounds like a challenge...   8-)

Got pulled up by a cop one day for going too slow on the JD wanted to book me for only doing 26 kph in a 80 kph zone.

He could not tell me the section of the traffic act when I insisted he quote it.

so he got on his radio and I could hear him repeatedly say "there must be something I can book him for" only to hear the reply "let him go"

Well I didn't get a fine but weeks later I did get a written letter of apology from the cop.

The JD will only do 28kph........the cop clearly was a lot slower

The first pic is the view from the rear upper compartment. These are the main pumps. all the valving is in the lower compartment.

The second one is the "power plant". Deutz 7.2L.

P.S. : It looks clean now because I spent 4 hours cleaning that compartment. Still have the hydraulic tank to finish cleaning and the front compartment. There was so much oil and anti-freeze in there that I had to wear hip waders and crawl in to get to the drain plugs.

Pretty cool Dennis! Looks like an adjustable wastegate rod...  [smiley=disimulo.gif]

Dennis,
What diagnostic interface does it have and can you communicate with it?

I would check for oil in the intercooler and intake and also see if there is a specification for crankcase pressure and ensure that is right.

If not it may need some work to the control valve.

Also check for soot build up in the egr system.

After the clean have you run it for a few hours to see if it stays dry or have you not got to that point yet?

Logic wrote on Jun 23^rd, 2018 at 12:25pm:

Not there yet : too many other things on the go right now so i had to defer that job.
Still need to finish some cleaning on the hydraulic tank and front compartment. The engine water pump (leaking) and coolant lines need to be replaced before I can run it for extended periods. All filters have to be changed too.
And we're also modifying a 50 ton scissor neck trailer to haul that beast around. It will have to travel to 3 different landfill sites, on a regular basis.

Logic wrote on Jun 23^rd, 2018 at 12:22pm:

Dennis, What diagnostic interface does it have and can you communicate with it?

There are two monitoring panels for all the subsystems, with colored blinking lights (indicates type or severity of faults) and a main button/light that flashes trouble codes. As for an external interface, I haven't even looked into it yet.

Just a thought........
You could record flashing light codes with the Picoscope.

This machine is testing me : From the time we got this machine delivered, the engine only ran about five minutes (after resolving the engine shut down issue) and there was some major fluid leak issues. Got the water pump and pretty much all cooling lines replaced and some of the obvious hydraulic leaks repaired. I started the engine to test for coolant leaks and right away notice an unusual vibration. Darn it ! Looks like the crankshaft damper is crapped out. Belts and tensioners are jumping enough to notice and you can see the damper "wobbling" up and down. Looks like the front of the engine compartment is coming out tomorrow.

Here are some short video clips of the engine running. Let me know what you think.

Looks and sounds good except for one or two fan blades. Wonder if a NVH capture wound pick that up...   [smiley=disimulo.gif]

You don't see that crank pulley movement ?
I pulled the belts off and ran the engine briefly and the vibration is very noticeable. So was the crank pulley movement.

Don't have a NVH.....but I'm willing to try it if you lend me yours lol.

No chances of that happening. Been short staffed since December and my shop hand/welder is going on holidays for the next three weeks. Only the apprentice and myself left to hold the fort. I currently have over 15 weeks of accumulated vacation time and it doesn't look like I'll be taking any until next fall.

Good point, Could you check to see if the crankshaft is bent with the NVH? If it's possible, how would you do it? Would you have to test with and without the balancer?

Denis, what's your next plan of attack on this one? Good stuff btw!

Ernest wrote on Jul 29^th, 2018 at 9:37am:

I will remove the damper and inspect it, check crank for lateral movement and runout (once the gout in my right hand goes away  [smiley=brickwall.gif]). I have strong suspicions the the front seal is gonna have to be replaced also, judging from the crap build up that was originally on the engine.

But on a good note, I ordered a 4 posts drive on hoist for the shop today. 40,0000 lbs cap. with a 30 feet deck. These old bones are gonna love it.

Would love to! That would be cool. Then swing over and see Larry aka stitchB

Had a bit of time to work on the beast today and as I suspected, the centering dowel wasn’t even in the crank hole: all of it was in the damper. Since it looks like this is the original damper (14000 hrs) I decide to replace it and the crank seal. All parts have to come from Germany so I’ll have time to do other jobs lol.

This is what I found when I took the damper off. Should be sticking out at least 1 1/2 inch.

Ready to commit arson : Had to make time to work on the beast. Engine is running OK (still has a vibration that worries me but Public works wants that machine badly). Flushed the engine oil twice and pulled the fuel filters off and found about 20% antifreeze in the 3 filters. Fuel tank bottom is all antifreeze. Oh joy !!!

Oh and I did voice my concerns when the management wanted to buy this machine. What do I know.

Do you feel the antifreeze is coming back through the return line?

As for the rebuild , no chances of that happening. The Only Bomag approved repair company won’t even touch the engine. I have to get the Deutz approved service center guys up here and they are 250 miles from me. I’ll be testing the system tomorrow by isolating the fuel return and monitor for coolant. It could be an old issue and they never cleaned the fuel tank.

With the kind of week I've had, you may want to keep that number for yourself, lol. Otherwise you would be accessory or accomplice to a crime.

So did this thing run successfully?

Yup, it's running. Still lots of work to do on it to bring it up to our standards but Public Works "needed" it to work in the landfill so they could demonstrate the benefits of having one. Gotta say that it does a good job of compacting garbage but found out that it doesn't float well in water  ::)
