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.

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!

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

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

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

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!!!

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

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.

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.

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!!!

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 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

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

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?

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.

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

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.

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.

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?

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

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.

Great tip!

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!

Thanks again - bit the bullet and got the engine pulled out today. To get the pump out, I'm guessing it's easiest to just disconnect the hydraulic lines and hoses, electrical connectors, and then pull the pump out in tack with the cast iron pulley housing (or whatever that's called) that has the 3rd engine mount? It didn't look like it had any mounts itself - just was supported by being attached to the cast iron pulley housing. Is that right? kzread.info6m3ySHVZx4w?feature=share

@marshallbell9354 yes that's correct. Pull the housing so you can remove pulley from pump shaft the pump from housing. I'm impressed you got it out that quick. You can mount engine to pulley housing and put it all back in as an assembly.
