Made by the Caterpillar Corporation SPLIT SECOND SHIFTS promotes their new D8 tractor bulldozer and the legendary Powershift transmission. The single-lever Powershift allowed the operator to shift quickly, with more power per load being delivered and resulting in more efficiency. The Powershift gives the power of direct drive and torque converter tractors through the planetary gear, as seen through animation at the 3:00 mark. At 7:30 the film shows the Powershift transmission up close, with the torque converter seen at 7:47. At 8:15, the film shows some of the Caterpillar manufacturing facilities including their legendary quality control operations and the Powershift assembly line at 9:10.
The Caterpillar D8 is a large track-type tractor designed and manufactured by Caterpillar. Though it comes in many configurations, it is usually sold as a bulldozer equipped with a detachable large blade and a rear ripper attachment. Several types of bulldozer blade can be used on the front of the tractor: Straight ("S-Blade"): A short blade with no lateral curve and no side wings. It can be used for fine grading Angle: held by an U shape frame that has three holes on each side, to set the blade to 3 positions: right, center, and left. Universal ("U-Blade"): A tall and very curved blade with large side wings to carry more material. "S-U" combination: A shorter blade with less curvature and smaller side wings Other blade types include landfill U-Blades, woodchip U-blades, and two-way blades for work inside the holds of ships.

My Dad bought a brand new D-7E in 1964 with the 3 speed power-shift transmission. Everyone else in Southern Indiana doing custom work at that time was using standard shift transmission D-6's that had to be manually hand clutched, the direction lever changed, and another shift lever changed if you wanted to back up at a high rate of speed. No one in the area had a hydraulic tilt cylinder for the blade, but the new D-7E did. Clearing land, building farm ponds, and bulldozing fence rows was the order of the day. The D-7E could do probably 2-3 times the work of the smaller D-6's in a day, and Dad only charged $35 per hour, while the D-6 owners were charging $30 per hour. It didn't take long for the farmers of that era to figure out how much more you got for your money in hiring the D-7E to do your work. At first they all thought they were being robbed, but the D7 could push a tree over in one swipe, that took a D6 15.minutes to take out. The total price of a new D-7E in 1964 was $40,000.

We had one of these old 46As with the land leveling outfit I worked for starting back in the early 70s. The torque converter used diesel fuel circulated from the fuel tank. On hot days when the Cat started running hot and the fuel tank was low, it helped to go to fuel wagon and fill the tank.

@tyfrank3427 3 года назад

The oil torque converters are much better. I think the first 3000 46As had diesel torque converters, and then they went to oil torque converters.

This Cat had a Pony motor for starting the main engine. It was a 2 cylinder gas engine that was an electric start, you used it to spin the big engine, when it was spinning fast enough you fed fuel it the main engine. This one also had a cable system instead of hydraulic for control of the blade and an oil bath air cleaner instead of paper. It was a dirty job servicing them.

@tyfrank3427 3 года назад

D8Hs all used dry type air cleaners. These resemble an oil bath but they are not. They have a cap on the bottom to catch dust, then above is a piece about 8" high full of whirlybirds to help separate more dust, and then comes one element. There's no safety element. We had a 1959 D8H and I ran it on jobs as recently as 2009. That year was extremely dusty, and I changed filters every 2 days.

@tyfrank3427 3 года назад

@@wakeupslaveamerica And if you operate properly, in those conditions, except for ear plugs, you don't need any of that. You certainly don't need steel toed boots to operate, because there's nothing to hurt you. Same with a hard hat. Most of the D8Hs still in service have a ROPS, and often the top of the canopy is 3/8" plate. if something goes through that, the hard hat isn't going to save you. Our business has received awards for safety, and yet we are lax on PPE. Society has taken the wrong approach to safety. For example, a trick question is how many accidents have seat belts prevented? The answer is none. The only approach to safety is prevent the accident from happening to start with. That's a much better answer than using PPE and calling it safety. PPE is often used to give visible evidence to make things look good. There again, reflective vests may have a place, but if you are in the operators blind spot, they are not going to do you any good at all.

The 46A series D8H came out in 1959. This film would produced in 1959-1960. The torque converter shown uses diesel fuel. This was troublesome and was replaced in 1961 with a new design that uses transmission oil. The improvement made the 46A series D8H the best selling D-8 to date and widely thought as the best D-8 Caterpillar ever produced.

Who developed the powershift transmission first was it Caterpillar or International or someone else? We have an old Case 600 Terratrac that has powershift like system only you chose from a gear and then you can go forward or reverse in either high or low. You can have one track running in forward high and the other in reverse high. It's a really nice system. Also have a IH TD25 that has a powershift transmission. Not as familiar with that machine as Dad got it after I got married so outside of helping him rebuild the engine and put it in the machine I haven't driven it much, maybe 30-60 minutes.

@Parents_of_Twins 2 года назад

@@jackgee3200 Thank you very much for the information. I guess I need to find a schematic of the systems because I'm having an issue picturing how it works. I was thinking it was similar an automatic transmission in a car but am not sure.

@Parents_of_Twins 2 года назад

@@jackgee3200 Brake operated steering? You can use the brakes if you want but usually don't as you can put one side in reverse and the other in forward. You have high, low and neutral for for both tracks in forward and reverse. So if you really want to flip it around you can put one in high reverse and the other in high forward and it will turn on a dime. I'm almost positive it is the terramatic. The main issue we have had was with the left final sitting in the seat perspective. My dad had a new one cast and since then it has been fine. Prior to that had quite a lot issues. Great little machine although damn near impossible to find parts for which makes it kind of a pain. Really needs a new undercarriage at this point. I think some JD 450 stuff will fit though so I think dad has some of those parts from a friend who does undercarriage work for a living. Scrap dude took 6-8 practically new rollers he had for Dad's TD-25 on him a couple months. Dad was pretty steamy over that. Not sure how that's going to work out.

@Parents_of_Twins 2 года назад

@@jackgee3200 I have a TD-6 myself. The rollers and chains have the same dimensions as the Dresser/Dressta TD-7E according to my track manual so I was thinking about converting them over. As you said it's getting difficult to find parts for those machines. Dad and I rebuilt the DT-817 that's in his TD-25B and the gasket set alone was 2k and that was 20 years ago. I am planning on starting a small business doing lot clearing and driveways with the TD-6. So far I'm adding more projects than I'm finishing though. Curse of finding good deals :)

@heathbauerle2787 4 года назад

I read that just use 30W for everything except the final drives that use 50W. I also read to use 10w for arctic conditions. Hope that helps.

@tyfrank3427 3 года назад

Very early powershift machines like this one have a fuel torque converter. My Dad and I have owned well over 20 D8Hs and Ks. The newer powershift models oil with the transmission, steering clutch compartments, and cross shaft. They oil together and hold 7 pails of oil. They use engine oil in the transmission. Here in Canada, we run 15W40 in the transmission, but if you live in a warmer climate, 30 is fine. The High Horsepower models use duo cone seals between the steering clutch compartments and the final drives. We use gear oil in the final drives along with STP or Lucas which prolongs the life of the final drives. On the low horsepower models, they use bellows seals which are prone to leakage, although some have been upgraded. Better use engine oil in the final drives on those, because eventually, the final drives will get filled to the level of the cross shaft. If gear oil gets into the transmission, the torque converter will overheat. We change the oils in the transmission and final drives every 1000 hours, and the engine oil every 100 hours. The direct drive models use the same oil. Hydraulics also use engine oil on the D8H, and will overheat with "hydraulic oil."

@tyfrank3427 3 года назад

@@LuisA7009 Then run 30 in everything. If the serial number is over 46A12885, (Yours may be a 68A) use gear oil in the final drives. We use 80W90, but 75W90 is better here. You would probably be all right with just 90 gear oil there. Also, I grease the universals between the transmission and torque every 100-200 hours, as well as the steering clutch levers and brake pedals. The fan and idler pulley should be greased every 100 hours and the rest of the machine should be greased daily. When servicing the transmission, There should be 2 filters in one long housing by the engine oil filter (s). Those are CAT 1R0741. There should be a magnetic screen under the transmission pump and another one either near the transmission oil cooler or under the seat, clean them thoroughly. When you do, you likely have to replace the o ring. Those are Cat 5F149. If those leak at all, they will prevent the pump from priming and they will cause you a lot of trouble. If you have an older model, there will be a transmission filter under the floorboard on the right side and one under the seat. Those are 1R719. The engine oil filters are most likely cartridge type. The part number of those is 1R0659. If it is equipped with a spin on, the part number is 1R0716, 2P4005, or the newer 1R1808 should also work. The final drives each have a filter and the part number of those is 1R0729. Finally, the fuel filters may either be spin on or cartridge type, and either way, 2 are used. the prat number for the cartridge type is 1R0724, and be sure to have a gasket handy when you replace those. The Spin ons are 1R0750. I hope that information helps you. Oh, and if it has the hydraulic tank on the fender, you can run 30 in that, engine oil is recommended and it uses the 1R0741 filter, same as the transmission. Also, if yours is the older model and you order the transmission and engine oil filters, don't mix them up. they appear to be identical, and they're exactly the same dimensions, but they are different part numbers for a reason.
