I had to buy the 753 to help do clean up after hurricanes here in central Florida, it wasn't really in my budget but needed it bad, so being able to save money fixing things myself is a big deal. Your video has the best real content that I needed, I'll be watching you from now on ...thanks so much.
I still enjoy the opportunities I get to work on equipment. You always made me try to figure out how to fix it by myself first then would step in if I still needed help. You are also one of the contributing people who made want to create my company with a higher level of customer service and repair quality.
We have just bought a 2003 bobcat 753, it has a ton of issues and bodges that the previous owners are responsible for. We are currently working through these problems. Your videos are really helpful, clear and well edited, you deserve a lot more subscribers. Hope to see more videos on the bobcat stuff. Many thanks from the UK.
Thank you so much for the comment! Let me know if you have any specific questions on your machine.
Was your only symptom prior to the repair an oil leak? Or did you have any creeping issue
@@tetradgroup I have a 753. the one side bolt for the Pintle Steering Lever seems to be loose, how do i tighten it?
@@kahlme927 should be able to tighten with a 9/16 wrench
I never write comments on RUclips, just wanted to say that you should keep up the good work on these videos. U are so helpful, and I can honestly say that I haven’t found a youtuber who knows these machines better than you. There is only one reason why you don’t have more subs that’s the RUclips algorithm. You will need to upload more often, if you want more wives…
I just bought an old Bobcat 753, and your videos are a lifesaver. A big thank you from Denmark.
Your videos are very helpful for me to work on my 773 bobcat. Thank you
Great instructional video for those of us who do our own work. thank you for your skill and knowledge. would love to see the vacuum unit you use to apply negative atmosphere on the hydraulic oil tank sometime.
You make the best videos on RUclips, with awesome video quality, you must be a gold bobcat technician
I’m a great follower of your videos, you know all the tricks (spring compression) it’s so educational to watch. Thanks for sharing.
Thanks for watching!
As most will agree, you are probably one of the best teachers out there. Keep it up.
Part numbers on these seals, O-rings and dust shields? 👍👍
thanks for sharing your experiences
Really good video, thanks for the help. God bless.
I love your videos! I know something that is / would be helpful for me is a overview of common problems when your working in a area. Such as these are common wear items that can fail, here is what we see, etc.
You do alot of that already just trying to give some feedback, thanks
Great idea,
Well described video. Great work. Much appreciated 🙏
So nice of you to say- I appreciate the feedback!
Another awesome video. My machine creeps forward would like to watch a video on how you set that.thanks God bless.
Thanks for the great information , I have 753 c series same issue oil leak from the Pintle shaft , may i know the part number on the seal . thanks
I need to do this on my 773. What is the best way and easiest way to drain the hydraulic fluid. Also you mentioned you had a vacuum system to use on the hydraulic system. Can you show a video of it. Thank you for your great videos. They are very helpful.
I have a 463 and it has a little back walk when I start it up. I have to push forward to keep it put. If I replace steering triangle, does that take care of that?
I have a &%# and one side drives and the other I need to put real pressure on to get a response. Have FITTER adjust but he just adjusted the brackets and thru his hands up. I was amazed to watch how simple you made theis process do you have any ideas that I can pursue (I understand I have given you a tid bit of info)
Thank you for the video gracias bendiciones...
Do you have a video on centering steering your videos are great searched through all of them and can’t find one of setting steering I have a 863 with steering issues removed top plate found steer triangle’s loose and pivot bearings frozen got all that taken care of and went to set steering sense it had a creep but found with the plate off the top of the pumps right pump finds center fairly easy but left pump fights to find center and it’s a really narrow section where I can find neutral but I was hoping to find a video to center the pump if you have that if not any information is much appreciated
Yes Thank you so much
Thanks brother 👍👍👍
Hey man thanks for the videos I help me learn a lot stuff about bobcat but i have a question my boss has a 763 and we call it the crazy one and the problem is that when you start the skid steer i will drive forward or backwards be him self or it will go left or right be himself and i will like to know is the problem to see if you know something o and another one is that once you start driving it it will lock and jump please help me
Steering linkage is worn and out of adjustment, I should have a video soon.
What oil do you use for hydro oil? I bought a used machine with no manual and there seems to be a debate on what oil to use. I have an S175 that is very similar to your machine and this pump video is really helpful and confidence inspiring.
Well thank you for the comment. Yes there's always going to be debate on what hydraulic oil to use. I personally use bobcat hydraulic oil. It is more expensive and it comes out to about an ISO 40 weight. However the Bobcat oil has a much higher zinc content for lubrication. If you were to lose hydraulic oil such as a busted hose or another issue you would want that high zinc content to protect the internal components if something were to happen. Not perfect but peace of mind if you can stick with the Bobcat oil.
Thanks for doing a great job on your videos. Keep up the good work. I have an s205 that has an unbalanced steering. It was a good view of the mechanism "linkage" from pintle through linkage. I hope to figure it all out. Some sort of balancing act it seems. Extend one rod and the other is inadequate. I'll have to go through your videos and see if you address that elsewhere.
I'm working on a steering video, hopefully be up soon.
A video on forward creep adjustment would be helpful to alot of people,
Question u mentioned that ur bobcat creeps forward I was wondering how did u fix that I have a 753 and was wondering how to fix it
It might be time for a steering rebuild however you can buy some time by adjusting the steering blocks on top of the pumps. They're probably worn and have some slop between the block and the bearings. It's not hard to do, it's just a little difficult to explain. Start by raising the machine off the ground, start the machine lower the arm bar release the brakes and then raise the cab at this point the side that creeps should be spinning freely off the ground. You'll see the centering blocks on top of the pump you'll need a 9/16 wrench to loosen the bolts just barely and then tap the bolts with a hammer to push the block tighter against the bearings until the steering becomes perfectly neutral. This is a very vague explanation but maybe it'll make sense once you look at it closer.
I have an A220 and rear left steering cylinder is leaking. Can I fix this from outside the belly of the beast?
Can you replace a roller bearings on the steering triangle without removing the whole assembly? my 863 version has a Allen key bolt securing the roller bearing, which is accessible, though looks like there is nut below it which may not be captured based on the parts diagram. Did not know if I try taking it apart if the nut will fall out without disassembling it first? The 863 has a hydraulic line running through the middle of its steering plate.
That has a center charge pump on it however you can still remove the plate and just spin it around the line and remove the triangles. That's going to be the easiest way.
@@tetradgroup Yes, I figured that... I was just hoping it was going to be an easier fix without removing the steering plate and pulling the steering triangle...
Great man
I have a f series 763. Lately my lift pedal get stuck going in the down position. All linkages look ok. Happens more when it was cold out. Valve is sticking ?
Sounds like an issue with float detent in valve. Remove the detent bonnet and see if that helps.
I'm trying to find the correct procedure to set the steering geometry, are there any good videos? Special tools? Does it have to be in the air and running to find the neutral position?
Great question, no good videos that I've seen on the steering. I do have plans to make one. Best to have in the air and running and it can be done without special tools.
@@tetradgroup thanks for the quick reply! I have limited time so I'm very thankful. I just got it in the air in hopes that it was the correct road to go down 👌 I saw another video of a tech doing that but no actual demonstration. So I'll try it and hope for the best
When you put the dust shield back on, you said the shaft was nearly worn out. Do you have to pull & disassemble the pump to replace that shaft or will it pull out the top like you mentioned the bearing pushing up due to hydro pressure?
The pintle shaft is part of the swash plate which requires a complete tear down to replace. I'll do a pump video soon.
Swash plate has to be replaced. T250 machine. Will the pump come out without pulling the engine or is it best to get the engine out of the way?
Thanks!
Thank you so much, i really appreciate the support!
I have an 05 t190 with the same issue, I want to fix it myself but having an issue find the part number for the seal...can u help, the kids at my bobcat dealer always send me home with the wrong parts
The vacuum/ sucker is a great tool
Do you have a part # for that dust sheild?
Where do you drain the oil?
Do you have a part number for the seal kit
What holds the axles in to prevent from coming off during operation?
I have a hard time now getting then out to replace seals, bearings and racers
There is a large retaining bolt inside the chain case, remove bolt and sprocket and press axle out
@@tetradgroup
Do this apply for my little bobcat 463?
Thanks for the help!
@@eliasservices yes but you have to remove the pumps to access the chain case cover.
I just going to let the expert do it, I know it will be expensive but I need to get off stress, thank you for the help
Can you do a vid on the steering adjustment? I have an 863 that has a little left reverse creep.. Would appreciate thanks@!
That video is definitely in the pipeline! I appreciate the suggestion. This is one that I have been wanting to do!
@@tetradgroup Awesome@!!
@@tetradgroup just checking if youve done it. No pressure haha
How do you fix the back creep?
very good video explained everything really good best i have seen on this job
Thank you 👍
The left side of my 753 was pulling in idle so I replaced the left steering triangle. Afterwards it still pulled to the left at idle. Any suggestions as to why?
Need to adjust centering block, I'm working on a video, hopefully upload soon
@@tetradgroup awesome I’ll be waiting for it! Also my lift arms quit working after I got it all put back together. Where should I start looking for the issue?
Obrigado muito útil
please send a link where to buy a sucker
Do u possibly have the part numbers for these seals i have the same problem ..thanks in advance ..and awesome videos man
Thanks for the comment, what model machine and first four of the serial number and I can get the numbers for you.
@@tetradgroup I'm looking for the same watched the vid which is greatly on detail and I can't find em for the life of me, changing the pintles too because our machine has terrible stick drift.

I appreciate your videos! I have a 743B. I was using it very roughly digging out a stump with a lot of tilting forward and backward of machine. Banging down sometimes. Now loader only goes up.
Goes down extremely slowly. One time it went down normal if I shut off engine. Tilt doesn't move either. I suspect something in the spool valve. I don't mind paying for your assistance through email or phone if required. It may be spaced out so I thought I should contact you first for how that would work. Thank You, Duane
Sounds like the auxiliaries are engaged. Male sure right drive lever is pushed to the outside.
Have you ever got a fault code M4622 on a T-190.and How did you correct this issue.
5V sensor supply out of range low, several things could cause this. It could be a bad controller, wiring, or a sensor. 5v sensors include arm bar sensor, oil pressure sensor, and RPM sensor. More information can be found at www.4tetradgroup.com
@@tetradgroup Thank you for Your response
The best
Is the same Ring gear on all 753---751
I'm not 100% sure, I'd have to research a little
Sir how are you. Sir I need help. I need to charge presure manual. S450 Bobcat. Thank you.
Not sure I understand, do you need a service manual?
@@tetradgroup yes sir I need to service manual charge presure.
Sir bobcat ssl S450 code H7404 main controler no comunication . Where is the problem coming machine?
Fuses?
Will the leak on the pintle effect the drive motor side from going weak?
Not usually, unless it's a very large leak.
My 1990 753 right pintle looks a little wet But not that bad. And it's a little weaker on that side going forward then the other side. But revers runs great. So I was just wondering. Thank you sir for the reply.
@@dalelee01 that could be an issue with the seals inside of the motor. I have another video of a drive motor reseal that would be almost identical to the motor you have.
@@tetradgroup thank you I will look in to it. I'd just order the services manual. Thanks
Hey my name is Lee Meredith I have a 763 and I am losing hydraulic power in my steering and lifting and curling all at the same time could you please help me out? Today’s date is Wednesday, April 20, 2022
If all hydraulics are losing power I would start with the drive belt, check the belt tension, it might be slipping.
I have change the belt already and have re-tightened it like three times because I thought that might be the issue as well and I changed my hydraulic oil filter but still no power is there a filter on my hydraulic valve body?
@@christianmeredith7187 no filter on control valve, we may need to speak so I have a clear understanding of the issues. If you would like to schedule a time check out the website www.4tetradgroup.com.
Thanks got it will be talking to you looks like tomorrow at six thank you
ho da poco un Bobcat 864 che dovrebbe essere la versione cingolata dell' 863 con comandi ahc, praticamente da quando l'ho presa non ho fatto più di 12/13 ore di lavoro per quanti problemi ha presentato, prime 3 ore di lavoro tutto ok, ho caricato 2 camion di materiale di scavo, il secondo giorno 5 ore di lavoro a spostare pietrisco e scoppia la guarnizione del pistone di sollevamento, il terzo giorno nemmeno 3 ore a sbancare terra questa volta materiale compatto continui allarmi di bassa pressione idraulica difficoltà a spingere e a sterzare con strappi alle leve della traslazione, ciliegina sulla torta scoppia anche la guarnizione del richiamo benna, rientro in officina allarme alternatore e spia ahc accesa, comando di richiamo benna non disponibile, sostituisco alternatore attuatore comando benna tutte le guarnizioni di tutti i pistoni idraulici e la cinghia di trasmissione della pompa perché troppo usurata (su consiglio concessionario Bobcat) si è bruciato anche l'elettrostop. Tutti i problemi elettrici apparentemente risolti , rimane la scarsa forza di trazione e il fatto che fermandola in salita tende a scendere , il concessionario Bobcat ha collegato lo strumento di diagnosi e ha controllato la pressione di alimentazione che risulta perfettamente nei parametri (29,5 bar al massimo dei giri) almeno a freddo o comunque senza che abbia lavorato prima di collegare lo strumento, a questo punto chiedo qualche consiglio su cosa controllare, io avevo pensato ai motori di trazione, ho dato anche un occhiata al manuale e sulla parte idrostatica parla di sostituire in filtro idraulico (già sostituito anche questo), e di due filtri sfiato carter che non ho capito ne dove siano e neanche la loro funzione, mi sapresti aiutare?
I have same issue but can't find part #'s. I have a 863 serial # 514416432. Been 3 weeks looking for parts please help. And thank you for help and videos. Keep up the good work.
