Hours, how high would you go?

[John 1594]

cant imagine a 6810 being a "pottering about" tractor, that would have been a frontline machine in its day surely? Only way you wil know is to view it, if the wheels are leaning in, the pedals are smooth and all the markings wore off the controls, and the rear linkage has more play in it that a cheap hore, you know shes seen her best

i've seen a Cat 226 skid steer with over 10,000 hours on and still going strong on original engine ...... and saw a Cat 928Gz in Oz on original engine, axles, trans etc with 28,000h........

the latter was traded in, and a buyer found before it hit the yard.........

 

[roscoe erf]

our jcb teleporter has 15000 hrs on same engine still lifts and is used every day truck i drive has a million ks on the clock still going strong you do need to view before making a decision but i would not let those hours put you off,

That's good to know because my NH, which might possibly have the same engine or a variant [if it's a 2 litre] is just coming up to half that.
Gen-set engines and those that run at moderate loads at moderate revs will, when well maintained, last much longer than a tractor engine. High hours done with few cold starts will have an advantage over an engine with very many cold starts for the same hours.

Until fairly recently tractor engines were designed for at least 7000 hours between overhauls. The best would have a 10,000 hour service life. Nowadays you will be looking at 15,000 hours for premium engines. Super-premium heavy engines, such as truck engines, 20,000.

In the same way, up until the 1970's car engines had a 50,000 mile design service life. After the Japanese invasion engines were better built to a 100,000 mile life. Nowadays car engines [and auto transmissions] commonly have a designed service life [between overhauls] of 150,000 miles with premium engines up to 200,000.

Now some people [one in particular] might well poo-poo these figures. But they are what these things are designed to achieve under average use and servicing. Well driven and maintained ones might well last much longer. Others might not make it and might have a weak link that causes premature failure that could well be uneconomic to repair given the likely age and cost.

tractors and cars service life peaked 10 years ago now they have went backwards,take pick up trucks every one is dodgy today but old hi luxs were good fer 200k miles

 

[multi power]

Every hour registered at average revs of 1500 is 90,000 times for the piston up and down the bore. 45,000 turns of the camshaft.
Some will average more revs and a few, probably not high hour tractors will average fewer. Some will be at light load and some will be heavy work. Some will be driven sympathetically and regularly serviced. Some will be hammered and neglected.

12,500 hours times 90,000 revs per hour means an engine that has has its crank turned and its pistons slide maybe 10", a full 1,125,000,000. Over one Billion times.

There MUST be significant wear in that time.

If it was a long distance truck, not a tractor, it would have covered 417,000 miles or 670,000kms.

Not an insubstantial amount of work.
If the gears were changed only once every two minutes on average, the ratio would have been changed 375,000 times.

On an average 35 hour working week it would have been run for nearly seven years non stop.

as i understand in australia 1 million miles is not uncommom for trucks so 417,000 miles is not that much

 

[Cowabunga]

Trucks in Australia tend to run on the flat, have few cold starts and run at a constant 1200rpm in work [or thereabouts]. They are also super-premium type engines not medium duty engines such as we find in tractors. You will find that the majority of tractor engines are now parent metal bore type whereas the vast majority of truck engines have wet liners and more easily overhauled when the time inevitably comes.
You will find a few million mile trucks in the UK and those that have done so are usually motorway haulers, but not usually without one overhaul.
A motorway long-haul truck might well average near 50mph at optimal revs of between 1200 and 1400 is about 20,000 hours. As I previously mentioned in a post above, these engines have an inter-overhaul design life of about 20,000 hours as an average. Some manage it, some don't.

Around these parts the same truck would be lucky to average more than 20mph, which means a million mile truck would have covered 50,000 hours, not 20,000 hours. This illustrates just how much operating conditions vary and this obviously has a huge impact on the operating cost and ultimately the life of the machine.

Heck, there was an UPS van delivering here the other day with 375,000 miles on it, but it did sound a bit sick.

i seem to remember my old g reg ford escort had near 250,000 miles when it died, i never looked after it at all, my jcb805b had about 10,000 hours on the perkins 6354 before i fitted a replacment engine

 

[multi power]

another thing to remember, 10,000 hours with a sensible driver who treats something with a bit of care is equal to just 5000 hours if its had an idiot in the seat who revs the granny off it and doesnt know how to use the clutch, stamps on the brakes and generally abuses it.

i would rather 20,000 hours with agood operator than 5000 with an idiot, no servicing etc

I remember the first petrol and diesel Hi-Lux that were not quite that good, although the gearboxes tended to spill their guts all over the road before the engines gave up. Many as early as 60,000 miles.

 

[roscoe erf]

we had a 93 ford transit that's gearbox and clutch let go at 255000 miles and was sold still running sweet with 300000 miles on it bloody good truck its replacement was a different story.

It must have been very much improved on the Fords I remember from that period that needed overhauling properly at between 60 and 70 thousand miles on average.
About 10,000 hours was average between overhauls on the 6.354 although some managed more. Once properly overhauled they would run reliably for a few thousand hours more of course.

Are you sure that you haven't forgotten an overhaul on that Escort? It is a 1990 version, so indeed should be much improved on the ones I mention above from the 1970's and early 80's. I forgot for a moment just how long a production run and how many versions of the Escort there were. It surely wasn't a CVH engine? More likely to be a diesel, but only if you religiously changed the timing belt every 30,000 miles or so.

A local 300tdi land rover has done over 420000 and has never been touched,the owner puts it down to it never getting cold.

The old 2.5di engine were one of the best engines made,gutless but they would run and run,shame about the newer ford shite.

that's very true although ours were the turbo version much better for pulling/towing etc

They are indeed very good, in marked contrast to previous LR engines.
What is wrong with the Ford engines? I've not heard of many problems with them apart from the industry-wide EGR valves from time to time. They are also used in the Mondeo and Transit.

They didn't sell the 200 or 300TDi direct injection without a turbo.

The earlier idi non-turbo 2.5 was OK but only 67hp but had a poor reputation. One of mine was great but another was dire, needing a new crank among other things within 30,000 miles. The idi turbo was thirsty, used oil and was a generally dire heap of an engine.
