Oil & Fuel Diesel Gal/Hr

[W5FL]

Looks like a cable hooked up to the transmission input gear that goes to the hour meter and tachometer. Guess that would be rev/minute x minutes at pto speed translates into hours and fractions of an hour. Don't see how the hour meter could read anything except hours at pto speed. Run 1/2 pto speed you get 1/2 hours. Guess if it looks like a duck, quacks like a duck, then it must be a duck! er hour meter that is - at least it says hours. /w3tcompact/icons/smile.gif /w3tcompact/icons/smile.gif

Bird,

The glow plug time is different even on the M Series engines. The M6800 has 0 seconds above 50 degrees and the M4900 and M5700 specify 2-3 seconds. Don't know if that is a function of the engine design or the fuel mixing design, but they are definately different.

p.s. Bet Marks tractor is actually making diesel with the Amsoil and he is having a hard time figuring out how much diesel he has had to drain off each week to keep the tank from over flowing. This in turn makes it very difficult to calculate consumption. /w3tcompact/icons/smile.gif /w3tcompact/icons/smile.gif

Wen, maybe that Amsoil really is slicker'n owl poop./w3tcompact/icons/smile.gif

They keep changing these engines so much I can't keep up with it. My brother has a GMC Topkick with a Caterpillar engine and you don't wait on any glow plugs, just hop in and hit the starter like it was a gasoline engine and it fires right off (of course it has an automatic starter fluid injection system, or some such). And a couple of weeks ago, my son-in-law bought a new F250 crew cab Power Stroke Ford, and you do wait on the glow plug indicator light to go out to start it, but I was amazed at the acceleration that thing has.

Bird - yep, the L-series tractors have a glow plug light that goes out when it's ready to start. I haven't looked at the shop manual to see what kind of circuit it uses, but I think it's just a temperature sensitive relay. Maybe they figure the average L-series owner isn't as smart as the averabe B-series owner. /w3tcompact/icons/smile.gif

Wen - Alright, alright, I said I haven't had a chance to look yet. Just for you, I hope it burns 10% of the fuel yours does. /w3tcompact/icons/smile.gif

Mark, I think having a glow plug indicator light to go out when it's ready to start is the best idea. Maybe they just figure you L-series owners spent more money and ought to have more bells and whistles (like having a brake indicator light that we don't have)./w3tcompact/icons/smile.gif Of course, if it were up to me, my tractor, car, and pickup would all have at least as many instrument lights as an airplane.

Bird - I wish everything I own had a gauge and a light for every function that has anything to do with a measurement of any kind: temperatures, pressures, voltages, you name it. I don't hate lights necessarily, but I hate lights without gauges.

Mark I wondering if that hsd doesn't do as well on fuel as my old gst? Noticed I have not posted about my fuel milage or should I say hourage. Is that even a word (hourage) well it is now.

Wen if that doesnt get him hunting that book nothing will/w3tcompact/icons/smile.gif

Another way to tell if your "hour" meter measures time or engine revolutions is to follow the cable from the meter and see where it goes. on my B2400 it goes to the injection pump, which is a dead giveaway that it measures revolutions, not time. It happens to be calibrated such that the revolutions when operating at 540 PTO speed is magically the same as time. What a surprise.

This does throw an interesting wrench in the works around the gal/hr question. Anyone reporting consumption figures will need to be clear if they are reporting real time, or meter time. If meter time, they wiull also have to report how their meter works and what speed they were running at.

For my B2400, I can only give a qualitative answer. I refuel very infrequently. I've got 80 "hours" on the machine and doubt I've filled up 8 times. I've spent the better part of two days cutting fields and not gone through a tank in that time.

Good point about the hour meter and the injection pump. On the other end I would say if the hourmeter is wired to the keyswitch than its safe to say its a straight time unit.
Guess this would throw everyones fuel measurments out the window as far as being accurate comparing two different hour meters. Actual time versus wear time.
