Great video as usual you make it look easy. As an owner of a 7753, I can tell you, your videos are such a huge help. Thanks much.

[@tetradgroup]

Thanks 👍

[@coltenjm10]

Great video, thank you for the in-depth detail, and being realistic on how to do it. Very nice video!

[@michaelj.dubritz7478]

Thanks for posting. I just picked up a 753 and the right front axle was leaking.. using this video, I fixed it! Only thing I did differently was use a slide hammer to remove the outer race. I had to buy the wrench and wrench extender, but now I have them.. Thanks again.

[@gregbannish8423]

Very helpful, similar to my 743 but there is less access to the rear chaincase on my 743, and hub and axle are 1 piece. The hardest parts for me was getting the sprocket back onto the axle, you made it look easy! And getting the seal installed straight and seated, since my hub was in the way. I didn't replace the inner race because I thought would be too hard to install, didn't know your trick with dry ice!

[@blorph1]

Super video. Don't own a Bobcat but when I saw the title of the video I just had to see how you did this. Wanted to up vote and comment but had watched it on TV so couldn't. But took the time to find it on the computer so I could commend you and up vote. Thanks again.

Your reminiscent of my former bobcat mechanic it would come and fix everything for me nice job thanks for sharing

[@terrylundquist2646]

Very informative video. I recently installed new axle bearings, races, seals, sprockets and chains on one side in my S300. With the help of your great advice, I was able to get it done. You are so knowledgeable, and I am so jealous.lol. Thanks for all the information you share.

[@tetradgroup]

Great to hear and thank you so much.

[@CHERYLHEDDELL]

I didn't realize that after guessing on the torque that going "click click" would certify the correct torque. Great to know that after all the years of guessing. On a serious note, I would tighten a simular nut to get the feel of it and then tighten the nut to tighten. Good video as usual. John

Dry Ice....who knew !! I would always put similar parts in the shop freezer. I'm sure the dry ice gives it that extra shrinkage to make the job that much easier. Great video !!

Thanks for another great video! What weight hydraulic fluid do you recommend for a 1995 763 C series, Bobcat or any substitutes?

[@tetradgroup]

AW46 is a good alternative for the 763

[@brianmceneaney4266]

On a S250 , for the same job does the body need to be lifted off the case? getting the rear cover off requires all the hydro plumbing to be removed? thanks.

[@Jimo225]

I got a 773. one of the rollers, (the thing that touches the sprocket), was brocken off the chain and laying at the bottom of the case. I been using the machine like that but am worried that chain will break soon if I dont' replace it. You ever have the roller piece break off a chain like that?

Brought to mind messing with early 70 mod. cats with the wide drive belt and variable action pulley for speed adjustment. Wisconsin motors they were still the cats meow back in the day. We had one with a single cly. Wisconsin motor. Should have said engine you know the rule.

[@estevanmendoza1170]

What brand is that Extendable 1/2” ratchet??

[@ExploringCabinsandMines]

Are those Spacely sprockets ?

[@oiu7890]

Is the machining of the tubes, axles, sprockets, cups and bearings that exact that no shims are needed to set the rolling torque of the axle? 🤔🧐

[@lukemorley7481]

ALL Right😮

[@Order-in-Chaos]

Hello there, great video. Perfect tips. I'm about to tackle an S300 rebuild, there's what appears to be a water cooling hose about 1.5" round in the way and other 3/4" hoses connected to some sort of a pump right on top of the cover. Also the 4 large hoses (hydraulics maybe) in the center are kind of closer together than what you have in your machine. Do I have to remove these hoses? All of them or which ones? I'd appreciate your input if you've ever worked on an S300. Thanks pal.

[@stephenrountes]

Those are all going to be hydraulic hoses, it makes the job a ton easier if they are removed. I’ve had some luck using zip ties to hold stubborn hoses out of you way on jobs like this 👍

[@Order-in-Chaos]

@@stephenrountes Thanks Steve, I was hoping there's a way without going through disconneding these hoses because they have larger than normal nuts which require me to purchase large wrenches but I guess there's no way around that. I'm going to tackle this job soon. Thanks again Steve for your input. God bless and Merry Christmas to you and your loved ones.

[@stephenrountes]

@@Order-in-Chaos Having a few wrenches bigger that 15/16ths is great when you own a bobcat. 1 1/6, 1 1/8, 1 1/4 and 1 1/2 are the only ones you should need. Merry Christmas and happy new year to you and your loved ones as well!

[@fredygarcia353]

Excuse me for a question, what is the exact size of the key?

[@440capnhook]

They make box end torque wrenches for jobs like that.

[@ExploringCabinsandMines]

Is my Bobcat 631 mostly the same ?

[@stumper798]

I tryed to get to talk to you but cant make your time frame, S175 will the lift tilt valve solenoid coil, make the bucket dump and not hold, but i can tilt the bucket down on the ground and pick the cat up but does not leak down, I have no leaks on the valve body

[@naj370]

anyone know where I can get a hub? bobcat discontinued the 6706075 hub.

[@joelsmith5886]

Nice video would you happen to know would this video be helpful to me when working on my S205 which is a good bit newer than that 753? Are the drive systems somewhat similar?

[@Rprecision]

Thank you for the tutorial, looks like my 763 is the same. What's your preference for chain case oil, manual says bobcat hydraulic fluid.

[@tetradgroup]

Thanks for the comment. I personally use whatever is available at the time. It's just a chain case and bearings. I think any AW32 or AW46 would be fine. I just filled this chain case with motor oil. Bobcat is selling their 2.5 gallon hydraulic oil for $80 so that would have cost me $320 to fill the case.

753 will hold about 8 gallons. You can use any hydraulic oil, engine oil or a universal tractor fluid.

i thought it was bad to use a gear wrench to break a bolt?

[@lanieeve1485]

some times they brake first...it's better to use a wrench just to loosen bolts...base on my experience.

[@garymallard4699]

🇨🇦🤓🤟

[@b.malnit8983]

Wow. Time for an extra pair of hands.

[@FrequencyOfThought]

My 843 was designed with a one piece axle, then the last model of the series they decided to switch to a 2 piece, so instead of just replacing the oil seal. you have to remove all the controls and plates where your legs go, my machine was so rusted it took me 3 days to get to the chain case. Then if you want to remove the rear axles you gotta pull all the pumps from the belly... What a joke... Someday I will replace the back 2 axles with the later model ones... Some day.

[@Pogimo68]

I bought a 533 and am going through all what you said. Everything has to come out and I had to cut the big hydraulic hoses (3 out of 4) all this to replace leaking seals. My left side is leaking so I have to do the back. Those axel bolts at the sprockets are giving me problems. But once it’s done it should be great. It would have been so nice just to take the hubs off and replace the seals. Good luck with your machine

[@FrequencyOfThought]

@@Pogimo68 I finally got mine running with a repower using an ISUZU generator engine 2.4l.. Then I decided to power wash it and the power washer eroded an access plate on the belly of one of the hydropumps causing it to leak. Now I have it in pieces and rebuilding that pump and had to locate a new casing for the pump.... Long story short I am ending up replacing almost every single hose in the belly and hard lines too.. What a PIA. But at least if I have to service it again those hoses will come off without the force of God F my life..

[@frankrobbins6680]

The 843 is that big of a job? Remove pumps?
