Bobcat Swash Plate Sensor, What Is It And Why Does It Fail? 

Hello friend, I'm from Chile, can you help me, unfortunately the representation of the Bobcat brand, in my country there is a company that unfortunately does not comply with the technical assistance and the spare parts are not in stock and only for import, in addition of taking 4 weeks each time a spare part is requested, the values ​​you charge us are practically high, we are working to pay for the spare parts. Currently, 2 elements were damaged (swich plate and coil of the High Flow) I am trying to find a spare parts distributor in the US to directly request the spare parts and skip the dealer in my country, is it possible that you can help me??? Bobcat T770

CNH uses a couple different version of this pump in their skid steers. The pumps they use have the charge pump integrated into that housing you removed from this pump. CNH also does not authorize their technicians to take apart these pumps. I have had one pump where the bolts that hold that end housing on broke at about 20 hrs on the machine and it just kept dumping all the oil out the bottom. There was also one where whenever you enabled hydraulics it would just drive one side in circles no matter the input. That one must have had broken servo piston centering springs or something.

You never say what the swash plate controls? Does it control the tracks? I have one that the tracks work for about 30 seconds, then quits. All of the other hydraulics still work, just not the drive. Since it moves for a short period of time, i know the motors are working, it’s an electrical problem. No codes. ZHS 430 Fast track.

Why would they use plastic? Why not something more durable like bronze, stainless steel, titanium, etc?

Thank you so much for this video, I had a t190 that the left swash plate sensor signal was erratic, ended up pulling the engine and replacing the sensor, reinstalled and did drive calibration and boom problem repaired, thanks for covering this though!!!

Just excellent! Your vids are clear, concise and easy to follow. I did learn quite a lot about taking care of my Bobcat just by binge watching your channel. Thank you.

I Started as a Service technician in The Shop at the Oklahoma city Dealership, I just wanna thank you for some nice content to watch. I love your organization and it seems you have a wealth of great knowledge and are very good at sharing your knowledge thank you sir.

You are a valuable source of Bobcat knowledge regardless if I will never undertake such a repair. I dont think my 7753 has anything like that. lol

A wealth of knowledge. This is called doing the right thing - forwarding your knowledge to others. Thank you!

So whats considered thenleft and right side? Is it with cab up looking at machine left is left and right is right?? Or would it be from an operators point of view. As if in operator seat ? If this makes sense 😅😅😅

I purchased a used T630 Sunbelt machine from an auction. Ran great until this problem, about 3100 hours. 7528 right side. I'm going to order the bushing and control arm and have purchased a service manual. The service manual speaks about remote start tool needed to run a calibration. Is there a way to replace these parts without requiring a full calibration? Can you speak a little bit about when a calibration would be required and ways to avoid a calibration if everything was perfect before this error code? Also the pump motor is painted a deep blue color on the case, I'm suspect that it could have already been replaced. Is there a common color for these hydrostatic pumps from the factory? Great video! Thank you.

I have an issue where on mine the cradle bearing cage breaks and the swash plate gets stucked. The bearing cage is some kind of plastic. It's a HST pump on a D31PX-21.

Help me please My bobcat tl 35.70 when I started my engine the sound sensor always ringing,, before not like that

My 2016 770 SJC rig is throwing the 7527 drive left Swash plate out of position. Recommend solution

My S750 gives a d7527 code and shuts down multiple times while going forward but has never done it backing up. Would it still be the bushing?

Hoping you have a minute for some advice. Just bought a 2016 T550 at auction (2,200 hrs) and it has code D7528 (rt swash plate out of position). I just did a hydraulic flush bc the fluid looked terrible. The machine will run/drive for a bit but it seems to almost always shut down and throw the code when backing up on wobbly terrain. I can run it up and down my driveway 200 yards long and it seems ok but can consistently get it to shut down if I go off my drive and then reverse back on to it as I turn around (there's a couple inch height difference at the edge of the drive). Not sure if there are any other trouble shooting I can do before starting down the road of pulling the engine and pump? I greatly appreciate your time and advice!

Hi I have a Bobcat T 590 track loader it is a 2019 it has an active warning code d7540 drive left swash plate out of range low , any advise for me ?

My skid steer s770 stuck going forward to the right as soon as I turn it on. Seems like its stuck on one side . I unplugged the electric joysticks but still goes forward as soon as I turn it on. Any idea what it could be ? Im not getting any codes either . Ty in advance.

Can I just unplug the sensor so I can finish this job? What will I lose by leaving it unplugged?

Im having issues with said pump. Bobcat says i need to pull the engine to pull the hydrostatic pump. Is that true. Doesnt look like id have to

I have a T-450 2016 D7528 error code where is runs and shuts down after running for a while. Says "shutdown" starts right back up but dies a lot once things heat up. Dealers backed up. Pump calibration first, if bad replace the bushing? Leave the sensor? Thanks for the video

I just love the tempo of your videos clear and easy to follow with little bits of inside knowledge (the spring preload for instance) that's important for us to know. I don't have a bobcat, but have 1000's of hours operating them.....I have an ASV and am sure some of this tech crosses over. Thanks for doing great videos!

Let's say a guy wanted to put high flow on his standard flow t630. The main component would be a triple gear pump swap obviously. How would this guy (me) go about it without taking it in? I know it will need a bigger cooler. Any other insight? Thanks.

Great Vid

Hi. I have a bobcat S650 from 2018. Error D7540 Are these sensors emergency or rather the wiring harness? Can you replace the right sensor with the left one, or is it enough to swap the plugs and another error will appear?

Very good video and detailed explanations. Thank you for that, Artur

Man I just put a motor in my company's t770 and now I'm getting the code for left swash plate out of position. I really hope it's damaged wiring or sensor. Not trying to pull that motor out again

I'm working on a bobcat loader T250 and I am having a problem with getting 2 swash plate sensor codes, I removed the engine and checked for movement in the swash plate sensor actuators and found no problem with either one of them so I replaced both sensors and centered it up pretty good and put it back together but still getting the same codes so I checked the voltages and I can't get the voltages down below 3 volts no matter how far I adjust it with the screws in it indicating that the swash plates really are out of neutral. Do you know how to adjust the swash plates so they are really in the neutral position. This does have the solenoids that controls the speed. The bobcat won't even crank over or turn on the fuel solenoid. could this problem with the swash plates out of neutral, cause it not to crank? This is a job where somebody else changed the engine and I had to finish putting it back together and it's been sitting for several years and I had to repair numerous electrical problems with it to get it this far so I don't know what other problems there might be with the unit but I have been told that the swash plates out of neutral could keep it from cranking but I don't know if it's true or not any help would be appreciated.

Outstanding! Thanks so much for doing such a great job with these videos...making the what-the-hell easier.

Educational video. Is there no way to take the pump out without removing the engine

Great video! Thanks for taking the time to do it.

That sucks!!!! Not sure on the failure rate but that has to be a expensive repair, 3k ?

Do you ever see the angle sensor leak? I have a t590 leaking at the swash plate sensor or input shaft.

Great explainer video. Thanks for sharing.

We had issues here in the west coast with the harness causing the fault 9 times out of 10.

Your videos have been very helpful. I own 4 different Bobcat machines. I have odd question tho, what brand is the mic you are using connected to your shirt?

I have a 2016 T-650. After throwing the swash plate code, the dealer changed the bushing. That didn’t work. They have changed the sensors. That didn’t work. They changed the wiring harness to the sensors. After 35 min, that didn’t work. Dealer and bobcat are throwing up their arms at this point. Machine only has 1400 hrs. Any suggestions on what can be done next? Pump calibration was fine. They want to put an entire new pump in now. Curious on your thoughts? Thanks for much!!

Awesome video, thank you!!!

I just got code D7527 on a brand new S450 skidsteer... what is the most likely cause of a swash plate error on a new machine?

Great video again, Thanks 😊

Thaks... a lots... you are The best

On a R series bobcat it's most likely the sensor, on a M series and below it's most likely going to be the plastic bushing

Thank you Very helpful

where do I find the bushing? local bobcat dealer is saying its not available.

Nice trick with the rope... I usually use a rubber band.

You’re a wealth of knowledge. We just spent 40k on a. Low hour a770 and it’s throwing a code for each side 7527 and 7528. Do you think if it’s throwing both it’s the controller or both bushings? Should I replace all 3 while I have the engine out. Pretty pissed about this ngl, but it is what it is

Great video bro

Where are u located at. Having problem2022 bobcat t770

Thanks!

Well done

I have this exact issue. currently I have the swashplaye sensors unplugged so that it will run in limp mode. Can the pump be pulled from under the cab or does the engine have to be removed. Bobcat quoted me somewhere around 5000 to replace the bushing

Thanks for sharing this valuable information about swath plate.

How much does it cost to change the plastic bushings? and where can i order them

Thanks!

謝謝！

That was very interesting to watch!!! Thx for that. BTW, I asked my Bobcat Service Tech about the hydro oils, and he said they ARE compatible to mix. So, yeah. Thought you would want to know. Again, thanks for doing your videos!! I learn quite a bit!!!
