I'm on a D11R pushing topsoil and using 1500 liters of fuel in a 9 hrs day working on a 10 degree slope The mine I work at supply the fuel and say It's using to much and it should do 12 hrs on a tank are they right. The dozer is one of the best I have driven performance wise so may be it's a bit more than 850 hp cheers
Is it a 9TR OR 7PZ D-elephant...??? Honestly I have a lot of trouble believing your figures. 1500 Litres in 9 Hours is 166 LPH. That is 3516 Fuel Burn from a 3508. In my experience a D11R will sip at 90 to 110 LPH in an average Job. FULL Stall Jobs will touch on 140 LPH. I have never seen a D11R suck a Tank of "Motion Lotion" dry in less than 12 Hours.
That seems a bit whack, is it blowing a lot of black smoke? You have some sort of issue if you're going through that much fuel. What are your air filters looking like?
Yes it blows black smoke only when winding up just for a few seconds though new filters It may of been opened up for more power. Can this be done on these motors easily I have been on it a while but manly ripping rock and fuel use didn't appear excessive Two of us operate it 3 days 3 off we both get the same hrs out of a tank I is a extremely good pusher but I thought more fuel dosen't allways give more power dose it. I will get the serial no when I go back to work. Cheers
I'd be getting oil samples of the engine oil done ASAP for fuel dilution mate, thats burning way too much fuel
If it has a U blade and 32" plates and is pushing solid all day you would be surprised what she will burn. The other thing is if it is a 8ZR (770HP) and it has had a later engine installed (850HP), well the 8ZR has a smaller fuel tank compared to later machines so possibly something going on there.
Checked out everything today all good. The A team did some research and concluded that in the conditions I am working in 150 liters p/h is ok It is 850 hp U blade beautiful pushing I have been on a few of these mainly ripping / pushing rock and for some reason this one performs exceptionally well It has series 3 on it if that means anything or may be someone stuck it on. Sort sounds like a V8 Mack
With series 3 on it i know this is something done by the QLD Cat dealer, Hastings Deering, you are in QLD i assume then? It would be a 7PZ serial number machine and you can get a large tank for them but it looks dog ugly IMO.
It came from QLD The group I work for wanted one in a hurry for a job in Hunter so that explains it all Cheers
Who are you with in the valley?
I thought you hardcore D11 guys might enjoy this pic. I saw this D11R headed down the highway the other day.
