Lightweight is good and what did I use it for it’s a lawnmower kzfaq.infoUgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one. But if you take care it does the job really well.

Best repair video I've seen , concise to the point, without minutes of much unneeded dialogue. Bravo and Thanks.

My son and I are in the process of doing the same to both sides on a Super Z. Your video was great, advice sound and practical. The best is how confident you are. Most of the videos we watched, the people acted as if they had never does this before. Thanks!

Smart guy and very competent mechanic. Saved himself some big bucks by being smart. GOOD JOB!

your "wobble plate" is called a swash plate and the "metal" on the face end of the barrel is the bearing plate which has the valve plate seated on it. Thank you for showing us a closed loop pump system. The shaft seal you suspected for water entrainment was over the gear pump that acts as a surge pump to makeup for internal leakage/ pressure drops. Also, the spring you warned us may pop should hold the internal check valve poppet. Thanks for the tutorial!!!

I just rebuilt both on mine as well. The internals had the same wear as yours with just over 900 hours on them. Works like new again. Cheers!

Excellent tutorial. I am about to do this and it's nice to see it done before going into unfamiliar territory. THANKS man

Thank you for doing this. I've been looking at quite a few Hydro-Gear tutorials and some of your observations are new and provide good insight. Yours is also the first to deal with separate pump/motor configuration mowers. I think I'm going to look at buying something w/belts directly driving integrated units bolted to the wheels, 4 component configs seem to be asking for more frequent maint work on the owner's part.

Great video ! Just did my 2002 Toro 62" pump rebuild. Almost the same setup.. Hydro Gear pump. My seal was leaking at the end of the shaft. 👍

Thanks for the video. With the help of your video I tackled my Hustler Super Mini Z. The wheel drive was shot so I ordered a new one. I tore down that side pump to check for metal contamination and wear. Luckily the metal stayed in the wheel drive and I cleaned the pump, hoses and cooling radiator. My Hustler dealer wanted $1015 plus tax just for over the counter price on the wheel drive. They also recommend that you change the pump on the side that you replace the wheel drive. I figure it would have been a good $2500 to replace the drive and pump including their labor. I found Buchallase.com had the Hustler part out of FL and it was $735 delivered to my door with no tax.

Thank you for a very clear and encouraging video.

Aside from replacing worn components, cleanliness is imperative. The work bench needs to be covered with something to keep debris from contaminating parts that come into contact with it. The unit operates in a closed system, thus, abrasive debris can cycle endlessly through the pump and wheel motor, if it is small enough to flow through the filter. The system should be flushed, filter changed, and new hydro fluid added, before operating the unit. If this is not done, minute metal particles suspended in the old oil will create havoc with the "mating of new components" and severely shorten their life.

I replaced one of mine three years ago with a used one. Still running great and i have a spare to rebuild...

Thanks so much!!! What a great job you did for us all ;)

Thanks for the video. Very helpful on my repair.

Thank you really informative, much appreciated

Thank for ur video it was very helpfull

The valve plate and seal kit came from Arkansas Outtdoor Power Equipment, and the cylider block came from Millford Power Equipment. Hope that helps

Dude fucking amazing video man. Absolutely Love It. I know what video ill be watching when I need to rebuild my pumps. Thank u so much

Grate job!

thanks i just needed to pull the pulley of my scag has the same pulley thanks watched it all. I got a whole new pump i think i will rebuild it old one at least tear apart. $452.00 i paid for the new one 1200 hours but the damper went out on that side which damaged the pump THANKS

thanks I was told you can not rebuild these what a savings

Very nice bro , thankx .

according that it is a hydrostatic system and you found destructions like that, you had,at least, to check a hydraulics motor too it is really important

Nice job 😀

good job. thanks!

what method did you use to clean out system,, did you fill pump with oil before re-installing

Glad it helped you.

I have been watching videos about hydraulic systems,including values, pum and so many I want to be specialist on heavy equipment like you what can I do?

good job

At around the 10:30 mark, I show the invoices with the part numbers on them

were the pumps whining before the rebuild?

I work at Danfoss and we build these pumps and motors. Looks like valve plate came off of endcap over time. There should be a timing pin for the valve plate on the endcap.

thank you very good video !

Thank you

thanks for the vid!

thank you very much - I'll sleep better tonite .

I have a husqvarna z4822 and i wondering if you can tell me where can i find it,for both side. I searched for it on different sites but I can't find it. Thank you if you can help me with that.

What are the specs for the cylinder block?

It's a Simplicity Colt, but its when Ferris and Simplicity merged. So, yes it has the same pumps.

@patsy fenters. Sorry, I don't have that info. I'm sure a Polaris dealer know what you need.

After you rebuild the pump and you reinstall it, do you have to worry about air in the lines? Is it as easy as rebuild and install?? Im doing this same thing tomorrow. Id like to get it right the first time.....Thank you for the video

What caused it to ground down like that.

thank you for your reply but its real hard to see the invoices so can you please give me the part numbers please and thank you again for a great video

Nice video. Send me a video how to repair a walker lawnmower hydro. Thanks

Hi good video but can you give or show me the part numbers to the parts you used Thank you

great video is this a pump or a wheel hydrolic motor mower

Great Job . Marathon Hydraulic Motors. Wheel Motor Exchange.

WHICH COMPANY YOU ORDER THE PARTS ? EXELENTE VIDEO .

Where can you buy the parts from please would you put a list on your site

can you lap the port plate and barrel in stead of buying new

What Brand is our mower? I have a Ferris IS1000Z 52" and this pump look exactly like the type thats on my mower

sorry, replied to the wrong video. Patsy, If you look at the second comment, you'll see where the parts came from. I don't know the part numbers.

U was doing good u should have should everything wow

Great job save that money

Where did you buy seals from

buddhika gunasekara....srilanka..hevy euqipment desel mechanic..,

I rebuilt the hydro pump and reinstalled and only builds pressure when motor is off and I turn by hand. When I turn motor on and pulley turns my pressure. Any idea what could be wrong?

was tring to read the invoices where you purchased the parts from.you were moving too fast. can u send me that website(supplier)info plz?

How come nobody never talks about pressure release valve

"These guys here look good".... That's the pump plate. At least take a minute to measure the wear with a feeler gauge so you know what you got since thats #1 of the two major reasons for a weak drive. New pump plate assembly is $35. Takes a special flow meter from Hydro-Gear to test these after you're done. They're right at $1,000. It goes forward/backward doesn't mean it will go up a steep hill after it's heated up to operating temperature for 45 minutes

Thanks for letting me know you don't have to buy the entire thing, but that's all I got out of this video, would have been nice to watch you do it, even if it's just for reference if I get into a situation when doing my own. So sorry your video doesn't help.

Not any more than usual

The problem was it became unresponsive and jerky.

Ms hydraulic pump repair work

Of course "you can't rebuild' these things........lol They want ALL your money.
