All,
Good afternoon - Been lurking for some time, but finally joined up to post a question. I recently purchased a Long 460DT tractor. I was looking for a project tractor to work, and this one fell into my lap. I used this site to check into the old Long tractors, so realize the pros and cons of them and what I'm getting into.
So this tractor hasn't run in some time, so I've embarked on the first steps to get it started, and hit a really odd issue....
Basically in summary, with some funny details below...What direction do you pull the throttle lever to throttle up or down? Essentially, if I pull the throttle lever towards me/down, does that make the tractor rev up? (Gosh this is hard to ask!) My only other experience is with an old Ford backhoe (model 555) and the hand throttle was up for faster, down for slower...
Here's the details...
So I set out to get this Long tractor running. I was told it last ran about a year ago. So I've changed the oil, new filter, changed both fuel filters, trained fuel tank, added fresh diesel and additive, put in a charged battery, and primed the fuel system. Checked coolant and hydraulic systems, and was ready to just give it a go and see if it would fire off.
I was also cognizant of diesel runaway, and I realized I didn't know the history of this motor and how worn it was, even though it has a claimed 650hrs. So, I was ready for runaway conditions, had the air intake tube open and rags handy. I also figured it was possible the injection pump could be stuck internally...
So I get it started, and must've had a bit of air still in the injectors even after a few bleed attempts, so it ran slow, and then all of a sudden starts revving up. I instinctively pulled the throttle lever DOWN, and it really cranks up! So, I go "Oh boy it's running away!" and plug the intake.
This was late Sunday, so I decided to go back to the service manual and plan my next steps. I realized I should've pulled the fuel cutoff to know it wasn't an oil issue runaway but maybe a stuck injection pump, etc...
So I keep thinking, and then realize, wait - what if pulling the throttle that direction is actually INCREASING throttle?
So I hit up YouTube, find a few Long tractor cold starts, and sure as heck it looks like pulling the lever towards you/down increases revs.
OK - so now I feel stupid, and sheepishly post this. What direction of the throttle lever is rev up vs rev down? Did I instinctively pull it inadvertently to full throttle? I realize YouTube isn't always the best guide - I spent many nights before this watching runaway videos thus my instinct to assume the worst lol!
To be fair, I'm very mechanical, I rebuild cars and gas stuff all the time, so while my question seems bad, I haven't had any issue doing the work on this tractor and none of it's been very difficult - well expect what dir the throttle lever goes lol. This is my first tractor but I've helped my dad repair his backhoe many times. I'm not a diesel mechanic but know the basics and secured a service manual prior to starting this.
And one more thing - does anyone know if Long had an Operators Manual for the 360/460 series? The service manual doesn't seem to get into some of the operational stuff...looks like some of it is standard but want to be sure there's not other oddities of these tractors in operation compared to standard issue...
Thanks in advance!

And, I think my instinct was messed up after watching all the crazy ruanway diesel videos on YouTube (the on with the NS locomotive shooting flames out the top is pretty awesome!), so I choked the intake before pulling the fuel shutoff. It was late in the day Sunday so I decided to hold off messing with it further to when I had more time.
