8V92TA Running Hot

[Birken Vogt]

The Deere diesel's are just as loud in the application(s) as the Detroit Diesels IMO.

I think the dB measurements are about the same but the Detroit noise is just more annoying to me.

To me the Detroit noise is more of a symphony, get those twin accelerators going on the TS14 its like playing the piano

Oh man, that is the main reason I kept my 12V-71T. You put 600kw resistive against that and it really "barks".

When I had the 671 in my and you were pulling heavy, it would really sound nice. Of course the English at the front of the truck and I'm at the back.

Detroit's have a high pitched whine in them that is in addition to the diesel noise that every other fixed timing engine has, and that whine really gets to the ears even when you can't hear it. A lot of Detroits also don't have a turbo, and that makes a huge difference in noise as well.

I once worked on a tug boat that had a pair of 3,600 HP V-16 Nohab engines and 2 8V71's powering the 150 KW gen sets. The Nohab's were so loud that you had to either look at the control panel or place your hand above the 8V to check for heat to see which engine was on-line.

One of my life's goals is to fit a 671 to the front of one of our TS14's, I see it's quite common in America but nobody seems to do it here, I reckon it would make a huge difference and be great when pulling power with the hydraulics and a full can

 

[cfherrman]

Scraper? What engine you have now because it probably would be gutless otherwise.

 

[Huffa]

Factory setup twin 471's

 

[cfherrman]

Well a 8v71 would be better, if you could find some sort of turbo'd one would be even better

I saw a TS14 once with a turbo 4-71 for the front engine

Back in the 70's I spent a lot of time keeping a fleet of TS 24's running. Good machines. 12V71 Turbo in front with an inline 6-71 turbo in the rear. They were push loaded with a D9.

I remember a fleet of TS-24s on a coal mine reinstatement job in South Wales back in the late 70s. I need to see if I can find some photos.

After a fun couple of hours looking through old photo albums I found these............
Merthyr Tydfil, South Wales, UK. Early 1976.

There was also other DD-powered equipment on site, including these Terex R50s.
Sold & serviced by the (in)famous John Blackwood Hodge & Co, known to all in the muckshifting business as "Deadwood Dodge".
The young lady in the 2nd photo was at the time my GF, later wife, now ex-wife.

Awesome. Green everywhere

So mechanic pulled the after cooler, I haven't seen it but apparently not that bad, so now we're this far do we pull heads? Is it ever even possible for crud to block water galleries in the heads and or block? If so is there anyway to reverse flush the system?

 

[mekanik]

The after-cooler can look okay and still be partially blocked.

 

[Huffa]

Enough to make it run hot under load?

 

[mekanik]

One way to find out. Its out so block the coolant passages that feed it and put the engine back together and see if it helped.

I've done this in the past with a truck when the cooler burst a seam and another couldn't be acquired fast enough. Only detriment was an increase in exhaust temperature which was easily compensated for by an easier application of throttle, and a slight alteration of the driving style. No long term effects when the replacement cooler arrived and was installed.

That's been over 20 years ago and the truck was still around till last fall when sold off. Not many grain haulers around here running straight trucks any longer.
