I worked as a cylinder tech for 5 years. I have a couple of tips for you. 1. Invest in smaller picks for more control, When peeling seals out. If you make a burr, the oil will follow it to bypass seals. 2. Flathead screwdrivers work wonders when putting in the u-seal. Feed the u-seal into the groove, and when the last little bit is sticking up use a wide flathead to push the rest down. 3. If you do make a burr with your big pick, you can use alittle sand paper to level it out, don’t over do it. 4. If you have burrs or pitting on your rod, you can polish them out. That’s what usually chews through the u-seal.

[@jerrysmith9780]

You just took the mystery out of replacing seals in the lift arms. I've always removed the entire cylinder and brought it to a hydraulic shop. The next one I'm going to try on my own. Thank you. Your Bobcat videos are amazing. Bobcat should pay you since you're teaching Bobcat owners like myself to become more familiar and comfortable with owning our Bobcat equipment.

[@jimcox6661]

You certainly make it look easy and I'm sure you took a lot of confusion out of the endeavor that I'm about to take on. Besides the knowledge it's really nice to watch your video with no belligerent talk or obscene music in the background overriding your voice. Thank you

[@Mieuss]

Glad to know for when I need to do mine. Your videos so far have taught me to replace tensioner on drive belt and now I’ve fell in a rabbit hole watching all your videos so I’m prepared for next problem. Thank you sir

[@j31355a]

Two weeks ago, using your video, I replaced both lift cylinder seals. Removing the gland nuts and removing the large nuts holding the piston in place were certainly the hardest part of the procedure. Replacing the seals themselves was a piece of cake. I would really appreciate it if you could do a video on replacing the seals in the tilt cylinder. Thanks for the excellent work.

Great video! The last pair of these I did I left it on the machine like you. Your videos are very well done and without a bunch of fluff or off-topic BS. Thanks for the link to the spanner wrench... I just added one to my Amazon cart. I use (used) the u-shaped one with a cargo strap to hold it onto the gland... what a PITA.

If I'm seeing how you have mounted your vice that's a good idea and I'm really enjoying your vids will help me out definitely when I start to repair things on my s250 4000 hours but haven't had any yet I'm sure they are coming

[@wiscano]

Your expertise and methodology is second to none. I have a 642B that I purchased all the parts for to add auxiliary hydraulics and its videos like yours that help us 1st time bobcat owners tremendously. I wish you nothing but good things for your generosity.

Today I was able to get the leaking lift cylinder out of my S185, but my air hammer drill isn't budging the nut at all. When you talk about heating the nut, are you talking about a propane torch, or something else to melt the lock tight? I could probably take this into our mechanic at work on Monday, but I'm bound and determined to fix this darn thing myself!!! Thank you for the video and your help.

Thank you. The only think I did not like is that I do not have your cleaness yet . Hahaha. Amazing! Still learning. You are great! Gracias.

[@woodywood7734]

Your videos are great. I especially like the format and camera work that you do. No nonsense and no hype just straight forward information. I was wondering if you have considered doing a video on older bobcats or maybe just skid steers and mini ex in general that are good candidates for homeowner guys like me that are worth purchasing and putting time into and which ones you think are good to avoid due to bad design or due to parts availability or any other pitfalls that turn these things into lawn ornaments. Anyway thank you for taking your time out to make all these

[@tetradgroup]

Thanks for the idea, I will have to do that.

[@janhalter]

Is this basically the same process on an S185? Someone told me the cylinder on the S185 is too long to come out the top without raising the arms higher that the safety stop. I just finished resealing one tilt cylinder, but just discovered that one of the lift cylinders is leaking out of it's top. This video was great though. Very well done. Made a lot of sense. The only thing I would change is to make sure that people know that the first two seals have to go in with a certain side up.

[@tetradgroup]

It will come out, it actually comes out at an angle after you pull the pin and retract the rod a little

[@janhalter]

Thank you!@@tetradgroup

[@ToddFathers]

I recently purchased an A300 machine that had the lift cylinder hoses detached for some time. What do you recommend for cleaning out the lines and or system? Thank you for your time/channel!

#1 out of 45 Hydraulic Lift Cylinder DIY repair video in the wild and probably the best self-help video in 12+ years. Direct to the point explanation, supported by best and safe industry practices - zero fluff. You are an expert at your craft; job well done! P.S. Going to tackle replacing the manual release valve. An overview on that would be great.

[@mies-bvd]

Hello, Thanks for the great videos! This one really helped me to get my hydraulic cylinder leak free (great info about all the seals required). Would love to see a video about adjusting the speed control plate to the right rpms for the engine. How do you read the RPM from a Kubota Bobcat engine and how do you configure it.

[@mattdeloff4348]

Great detailed video, thank you! I have a T190 and need to replace the seals but not sure of this method will work. Your lift arms have that gap where you can pull the piston up and out (where the pin goes through). Mine are tubular steel, so I won’t be able pull the piston through up and out. So I’m not sure if this method will work with medium size framed machines (S175/185 and T180/190).

[@GingerbreadTrim-zp5ys]

I came upon your T300 Bobcat cylinder video ( Just what I needed). I have an T300. Everything worked great and I was on my way. When I got to removing the shaft though I was stopped in my tracks, It will not move. I can not budge it. You mentioned the suction that can hold the shaft in? I'm afraid of damaging the shaft. Any hints? The video is great and explains every step clearly. I know it will work, I just have a stubborn machine.

[@tetradgroup]

Did you figure it out? Make sure to loosen hydraulic lines to prevent suction holding rod in.

[@dscripps]

Watched your video to change out the seals in my T190. I appreciate your detailed content! I’m not a mechanic, but can follow directions. You saved me a ton of money! Thank you!!

Thank you for your video. It’s very explicit. I have to replace the gasket in a piston and before I watched your video I didn’t have any idea about how to do it. Now I know how thanks to you. Thank you for sharing. God bless you.

[@garygreen5243]

Man very informative video well done buddy I need this done on my bobcat

[@garygreen5243]

Is this why it's important to pressure wash your machine when done using so the dirt doesn't wear the seals?

[@mart16100]

My t 190 has leaky lift cylinders. After watching this video I think I’m going to try fixing it myself.

[@mattdeloff4348]

Same.. but I think ours might be a little more tricky based on the research I’ve done. The lift arms on the larger frame machines have a gap between the two steel edges. That allows you to slide the piston rod right out. Our T190’s have a solid tubular lift arm with no gap.

[@jeffjones2227]

Has anyone tried this on a t190 yet?

[@devinhouston]

@@mattdeloff4348You are right, can’t lift the rod out of T190 cylinder. Just take the whole thing off.

I have a 2014 S530 that needs to have seals replaced. My problem is, the data plate with the serial number has been blasted and painted over. How can I find out exactly what seal kit to purchase with out the SN?

[@megavoltelectrocycles]

The lift arms must be angled a bit diff on M series. For T650 I had to use a forklift to raise my arms 8+ in higher than they would sit on the safety U bar to get enuff room to pull my rod out. I sure could use big MILLIE right now! My milw has 1600ft lbs and its useless. Damn you make this look easy but its quickly reminding me of my Ex … STUBBORN and BITCHY as Hell. That nut is on TIGHT with the thread lock ! 😅. Thanks

[@hunkeeeboy7062]

Did a similar DIY on my trucks Ram. Costed me only $100 for seals. Ram works like new. Shops were quoting 600 to 800 and were saying they will also need to do sandblasting of barrel and re-chroming of rod.. Talk about over engineering or they are just scamming.

[@salvor1]

so what is your 'favorite' method for removing stubborn ends? I just sheered a pin from my gland nut wrench with a 5 ft cheater. didn't budge. A pipe wrench will just distort it.

[@yLeprechaun]

Wow. I just took mine off and took to hydraulic shop. It's a 1974 M700 and they're telling me it could $400 if the heads don't come apart easy. Maybe I should go back and get 'em. 😃

I cant get to the most important part in your steps. My ‘14 T650 isnt allowing the rod to come out the top. Looks like its running out of room up in the arm and pinching into where the arm bends. Im using a fork lift to help lift it out too. Whats the best way to knock out the pin on the bottom? Looks like it would be hard to reset from the inside of machine. Theres room inside to push it Full in and then reset from the outside too ? Thanks !

Yes they can be done same way. the problem is if you rely on the cylinder guard to hold arms up the cylinder rod end pin may be difficult to remove because the cab will be in the way.

[@c165vin]

Just had my 863g radial lift cylinders resealed. Unfortunately my bobcat dealer did the job because I don't have the shop to do it in. They found the left cylinder head wouldn't come loose. So basically I had to purchase a new cylinder. Have you ever run into that situation? Thanks for a great video.

[@tetradgroup]

Yes on the older machines I have run into that situation. The head is aluminum and the barrel is steel so over time the dissimilar metals corrod to one another and makes it impossible to remove. I have lots of tricks but sometimes the cylinder needs to be replaced.
