Here we continue to repair the charge pump now that the cab has been removed from the John Deere 9570R. I’m going to get to the root cause of the failure and make this tractor like new again. #johndeere #johndeeretractor #johndeeretractorpower #johndeeregreen

@robingerrets1077 2 жыл бұрын

Yeah, extremely well engineered. In order to replace a pump, as a maintenance engineer you just have to unhook numerous bolts and hydraulic lines so that you can lift the entire cab off the tractor. In order to set the cab aside, you just need some big wooden blocks, because it would be ridiculous if the cab could just be placed on the ground without wooden supports. This process just takes half a day. Then you just have to take off two wheels in order to gain access to a set of bolts and hydraulic lines on the bottom of the pump assembly. Then you need to remove a lot of dust and dirt that is below the now removed cab, so that you can unbolt yet another set of hydraulic lines and bolt. Now you just need some acrobatic skills to remove the actual pump assembly, which was built with one undersized sprocket which was destined to fail on this giant tractor. In order to finish the installation of the new pump, just reverse all operations you just did. If you’re a good mechanic, you can probably pull them off in yet two more days. The customer will be super happy with this marvelous piece of maintenance friendly engineering, because that 10 dollar sprocket will cost him no more than a week of lost productivity, thousands of dollars in repairs (including an expensive recovery) plus a few parts. Really well engineered John Deere…

The engineers really should bring the techs in when they’re designing tractors in order to do a better job to make it a little better to get to bolts and hoses. Better for the tech and the customer who has to pay for labor. It seems like every industry has this issue when designing. I really like the education you bring and the level of technical information

Amazing that you can get all those hydraulic lines, coolant lines, refrigerant lines, cab, covers, and electrical harnesses back together without problems in addition to the original one! I suppose the designers of this equipment (as well as most vehicles) do their job while assuming that it will never need to be serviced.

From the UK. Your video facinating. The loads on that tiny hydraulic pump spline can be clearly large! Not familiar with JD kit, but does that multiple pump pack also drive the articulated power steering? Those duals can force high initial loadings! Almost 78 years. As a youngster in the mid 1960’s I was involved in the testing/measuring of small tractors at a UK government agency to develop safety cabs, suspension seats and reduce noise following UK fatalities on farms from tractors overturning, noise induced deafness and back related injuries. An objective was to produce a British standard, and tractors were also getting larger. An ex WW2 airfield runway was used to ensure a consistent surface to measure on using a dynamometer car. I had a microphone attached by a frame close to my ear whilst driving a test tractor.

When it's still under warranty, it's all fine and dandy, but wait till these things are 8 years old, still cost over $100k to purchase and it costs $20k or more for a repair. Part of the reason prices on old iron are skyrocketing.

@davesawyer497 2 жыл бұрын

Many thanks for this series of videos. One thing that is clear is JD didn't consider serviceability in the design. What a lot of dismantling and major access problems to replace a pump. I sense you are getting a lot of satisfaction when you can drive your patient around the yard and feel it ready to get back out in the fields once more. What kind of costs would this job being accruing? Parts and labour? This isn't take you five minutes to complete after all. I live out in the country side in the UK and we do have "Green iron", but not as big as the machines you play with. You never see twin tyre configurations here as they wouldn't fit on the roads. However there is plenty of plant about and now when I pass a tractor I am thinking about ZK.

Zeth Why is that hydraulic pump referred to as a "charge" pump ? My guess would be it is because it supplies oil to a series of "stacked pumps" , rather than have them try to suck inlet oil themselves. There is an electronic circuit that does something similar & it is called a "charge pump" as well, but it moves electrons & not oil. Great videos Zeth...I troubleshoot & fix a lot of electrical & electronic problems for local farmers, but at 81 I don't work on any mechanical things at all. I love your videos....you are one Hell of a mechanic !

@@ZKMasterTech Thanks for replying really enjoying your videos. What I was trying too get at was pressure times flow equals power.

@2xKTfc 2 жыл бұрын

The pump input shaft almost looks like it's designed to fail there rather than force torque into a system that's hydro-locked. Only the work required to change it makes me doubt that theory, normally such intentional weak links are at least a little easier to get to... and wouldn't require changing all the pumps all the same. I do think that the pump stack design itself is really clever! And, uhm, space-optimized with the hoses in there. haha
