Series 7 Dump

[Marybelle Bailey]

Hasanyone discovered a brain dump sheet that helped get them through the exam? I used one for my SIE and did not use one for the Series 7 but I am curious if maybe Achievable could create a sheet to memorize going into the exam that will help with certain questions.

Other heavily tested Series 7 topics usually include debt securities (municipal products in particular), options, taxes, investment companies (mutual funds in particular), and dynamics of brokerage accounts (e.g. fiduciary accounts, required information to open different types of accounts).

I have two seperate 986's that I have questions on. First one we put a clutch in and I have the free travel set up but I have a question on setting the dump valve becasue the light wont go off till you have your foot all the way off the clutch. I went to adjust the dump valve rod but my I&T book says 3/8" of an inch of the spool should stick out. Is that to far? I also need to replace the rod and nut because the threads on the rod are chewed up so ith there a good place to start or just go right for the 3/8"

The other 986 I am having problems with just started to today. My brother in law has been running the tractor this spring and today he called to say the lube light was flickering on and off some times. He checked all the fluid levels and they were up to snuff. I ran it for an hour and the only time I could get the light to come on was at an idle when hot. This tractor had a new T/A and MCV pump last year. I also noticed that the light didn't always flash when the T/A was shifted. I checked the dump valve and It was adjusted to just barely out of the housing. I havent put a gauge on it yet but do you guys think it might be a linkage problem. It does seem like you have to let the clutch out a little farther this year to get the light to go out.

First thing to do is to set up the clutch with extra free play. This is usually to your own liking, but I set them up so that the tractor starts to move when the heel of your boot is still on the floor. This makes it easier to feather the clutch for hitching equipment or moving a few feet in the lineup at at the elevator. Don't make any adjustments on the booster, only on the turnbuckle going on down to the clutch release shaft (which requires a 9/16" wrench to loosen the locking block and a large flat screwdriver to turn the adjusting screw on the '86 series and two 15/16" wrenches on the older models without the booster, or two 3/4' wrenches with a booster). Once you have this adjustment where it is comfortable, make sure that the lube oil tellite is operating on the dash. It should come on when the clutch is pushed all the way down. Adjust the linkage so that when in High range, 3rd gear the light should go out just before the tractor starts to move as you slowly let the clutch out. Now adjust the transmission brake. Run the tractor at idle speed while the speed transmission is in 3'rd gear. Push on the clutch and count 1-2-3- and try to slowly shift to high range. It should go in nicely with only a "clunk" from the gears. Any adjustment tighter than this will make it difficult to shift on-the-go. Try to adjust this accordingly. Remember to break loose the jamb nut before removing the locking pin.... they sometimes require a little persuasion.

I have been setting them up this way for quite some time (and follow the order) and it has worked well. Remember to lube all of the shift linkages on top of the transmission from time to time, and you will have a super nice useable tractor.

I would add that on the 86 series clutch booster to make sure the upper links that attach the clutch pedal to the booster input rod do not have any lost motion. Adjust so that the links are free to wiggle by hand but so that the rod starts to move as soon as clutch pedal movement commences.

Lube light flickering....Put a gauge on it and monitor the pressure. Should be 18 psi minimum but I'd rather see 20-22 psi. If the pressure drops off at idle and picks up as soon as the engine speed is increased there might be nothing wrong that would require a tear down. (there is a page in the 86 series IH manual that explains the parameters for acceptable lube pressure)

I followed those directions when I set the tractors up. My I&T book says that any time the clutch is adjusted the dump valve should be too. On the tractor with the light flickering the lube light when out just like it should so I didn't adjust it after I put the clutch and T/A in it. Now it comes on at an idle when hot. The idle is set around 700rpm and it will go back off around 1000rpm.

The Muncie E and EH Series dump pumps are designed to meet the needs of the dump trucking industry. Muncie dump pumps are available in both direct and remote mount configurations; standard or extra-large port sizes; two or three line plumbing; and air, cable, or lever shift.

Many dump bodies function quite adequately with a 2-line design. However, a 3-line system includes a separate line to return hydraulic oil from the cylinder directly to the reservoir instead of forcing its way back through the inlet line.

The separate line is recommended when used for road building or stockpiling material because the 3-line pump allows faster down cycles, provides an easier method of filtering the hydraulic oil, and ultimately runs cooler.

The Muncie Cast Iron/Roller Bearing Pump Red E/EH Series is warranted against any defect in material and workmanship which existed at the time of sale by Muncie, according to the following provisions, subject to the requirements that the Pump must be used only in accordance with catalogue and package instructions.

Three Year Warranty. Both the Muncie E/EH Series Dump Pump and CS/TG Series PTOs are warranted for a full three years when combined with the Complete Muncie Tractor WetLine Kit with Polyethylene Hydraulic Reservoir and Hoses (3 line systems only). All additional warranty details described for the Polyethylene Hydraulic Oil Reservoir applies.

Warning. The above warranty shall terminate if any alterations or repairs are made to the Pump other than at a Service Center owned by Muncie, or if the Pump is used upon any equipment other than the equipment upon which it is first installed.

As to any Cast Iron/Roller Bearing Pump Red E/EH Series which is rebuilt and retested at a Service Center owned by Muncie, the period of the above warranty is extended for a period of one additional year from the retest date.

The Tommy Gate G2 Series is a dual-cylinder, parallel-arm design which utilizes a pair of hydraulic cylinders to lower and raise the lift by applying direct power to both sides of the platform. G2 Series Lift-N-Dump models include all the same features and functions of other G2 Series liftgates, but also offer a unique dump-through capability to be used with dump bodies.

With a 7-gauge floor, high-rigidity sidewalls, and a 3x2 tube top rails, it won't be easy get the Pro Series dump trailer bent out of shape. And its many user-friendly tools mean you'll also keep your composure. Need to bring extra tools? There's plenty of space for them in our large pump box, and the interior lighting will help you find them when you're working after dark. Ready to dump a load? The integrated hold-back will keep the doors in place.

These are good questions. I wouldn't hesitate to go ahead and upgrade to the latest maintenance release, R10.9 at the time of this post. If you notice a pattern of instability or see exception reports along with uptimes less than you expect, then it's probably time to call support and open a ticket. If there are power issues, then the exception report could be incomplete. I don't understand the process for exception reporting very well. Either way, you'll probably need to open a support ticket to have the exception report analyzed. If your 3400 series unit exhibits a pattern of trouble following the firmware update, I recommend calling in right away.

I would like to add the following new information that I have learnt:

There are two ways to generate LAMMPS dump files during simulations:

a. Entire data over multiple time steps written to one big dump file.

b. A separate dump file generated for every Nth time step.

I have tried loading the data using one big dumpfile (file attached). Paraview is able to load the data and run the animation flawlessly.

However, for my work, I would like to have separate dumpfiles for each Nth step, since each of these separate files is large. A combined file would be too big.

Designed for wide body mining dump (WBMD) trucks operating in more severe duty-cycles and harsher conditions, Allison 4800 WBD transmissions provide an extended torque range and a higher gross vehicle weight (GVW) capacity. They are highly regarded in the mining industry worldwide for their unrivalled performance, quality, durability and reliability.

Major Chinese mining equipment manufacturers, including SANY, LiuGong, XCMG, PengXiang and Tonly, outfitted their WBMD trucks with Allison 4800 WBD transmissions in the first half of 2023. These trucks were exported in large quantities to Indonesia, Saudi Arabia, Colombia, Brazil, South Africa, the Philippines, Ghana and Eritrea for strip mining and ore transportation.

The Allison 4800 WBD transmission can perform full-throttle high-torque starts and easy ramp starts, eliminating manual transmission issues such as difficult starts, easy-to-burn clutches, and failures to shift gears on a slope, which could cause the vehicle to skid. In addition, the transmission can automatically and intelligently shift gears in response to changes in road conditions and slope gradient, keeping the engine running efficiently without power interruptions and enhancing the vehicle's uphill dynamics and safety. The integral hydraulic retarder in the transmission assists braking without thermal decay, and when used in conjunction with the constant speed downhill function, prevents over-speeding downhill.
