Great job. I ended up watching trying to replace a radiator hose and saw the other belt was off. Glad you identified it as you were putting it back on--the fan belt.
Exceptional job filming something so difficult to see. I have watched numerous videos on this job and yours is by far the easiest to follow. Exactly what I needed, thank you sir!!
_"That's another project for another day..."_ Meaning it's not going to happen😂😜
Thanks for the video. I found out I needed to replace my tensioner when it started to throw 05-14 code.
This excellent training video helped me get my T180 back in operations! Thank you!
You made that look real easy. I don't remember it being that easy. I had problems with the tensioning process. Thanks for the video. Nice job.
Your videos are INCREDIBLY helpful!
Thanks so much!!
Thanks for the video. Everything was explained in detail. Job well done
I've watched a few videos on the belt tensioner. You explain everything and show everything. Keep doing g great videos. 👍
Just yesterday had to do this on my S185. Mine took me longer. You made it look easy. Nice video.
Thanks for this video. Just did a belt today thanks to this post.
Super helpful informative. Thank you so much for sharing this with us.
Great Video, Thanks. My belt stared screaming this winter while I was plowing snow... I sure as hell did not what to do it then LOL. And thanks for the comments on the aftermarket pulleys I did not want to pay the $400 bucks for a new one.
It seems that often times when I have a wear and tear issue that you have a very concise and well recorded video available.
Thank you very much for uploading and sharing
This is amazingly informative and useful thank you.
Thank you! Theses vidoes are so helpful
Thanks so much for the informative video. It helped me alot
Excellent video. Helped me a lot! Expensive part.
Excellent video!

@@tetradgroup got it done almost effortlessly. Many thanks!!
Awesome video, thank you 👍🏼👍🏼
Another great insight
Thank you it was very helpful
Thanks man.
Good video.
Great video. Thanks for the info.
Thanks for watching!
Thank you!
Just got a new tensioner from California couldn’t get it in Ireland for skid steer 751
The best man
thanks for the video, tensioner wouldn't fit in my vise, but a big digging bar worked great to get the cams free.. tell you what's a pain in the a$$, is that fan tensioner pulley that thing whipped me
Awesome do helpful
Thanks, bro!
Happy to help
full detail video. thanks man... I removed the belt cover with 3 clips. left them at the customer's place, went back, and only found 1. like wth... but oh well... Thanks again
Thank you for the comment, that's why I said you're lucky if you have all three. I honestly believe those clips have legs lol.
@@tetradgroup and wings... lol lol
It don't get any better than that!
Hey I install a new tensioner pulley and a new belt. like you have in the video. after starting, the belt jumps off the hydraulic pump pulley. ruins the belt. Please tell me what is the reason?
Is there a way to install new timing belt without a tension tool
Oddly my T650 runs pretty dang good with the tensioner ( not under tension). The spring load gives it enough force. Reason: my foreman overtightened bolt and broke it in the block. I had to drill it out but i felt it push thru. PLEASE TELL ME THATS NOT A CLOSED HOLE IN THE
BLOCK. ( which i opened ) Thats not the inside of the actual block is it? I took a pic in the hole The steel looked very clean 😮! Thanks for all the vids!
What causes the belt to split in slits ?
Have you seen knobs breaking off drive belt? It has happened to me twice not sure why.
I have a squeal coming from inside that cover at 2300 rpm and above, constantly.. seems alot more in the way to get the cover off.. you think a tightening it need or just
Replace the belt and tensioner
Likely those spring clips are there somewhere. They tend to fly behind the engine and hide. They hide very well.
They sell the parts to rebuild this tensioner.. Have not found a video of how to do it though
Is this the same on a bobcat 873? Thanks
does anyone know what the size on the hyro drive belt on a s185 bobcat skid steer is?
Nicely filmed video. One question, does it matter whether the numbers on the belt face toward the motor or away?
Thanks and great question, the belt is not directional so it can be installed either way.
I like it simple
On the cooling fan belt. Do all the pulleys line up straight? I have an 864 and the top pulley is about 3/4 of an inch to the right. So the belt comes off the idler pulley and has a lean to the right. I replaced a broken belt and the new one only lasted an hour. I may have had the wrong belt, it was thigh and very difficult to get on. I checked the motor mounts and they look good.
The tensioner bushings wear out and get out of align. If the tensioner is leaning I would replace.
I wish I had a skid steer owned by you
That could be a reality!
@@tetradgroup just waiting on you at this point
@@firewoodsolutions No one can repair/rebuild a skid steer like this person!
Indicator won’t move under tension. Put it in a vise. Help
I have a 2001 bobcat t190 and there is a hammering noise conning from the flywheel area and I have replaced the drive belt and tensioner, machine runs perfectly but the noise it very annoying and fluctuates with the rpm and stays the same under a load, any ideas?
Remove the fan belt, run it and see if noise is still there
Found my problem. Blower turbines basically stuck. Oiled best I could and spun up with compressed air. Fan switch not able to get the blower to turn. Would spin up if I tapped on the housing, but would not start on its own. Idea for new video -- How to replace blower. :) Thanks again. Jay
Glad you figured it out, I thought it was blowing out of the lower vents but not the top which made me believe the blower was working.
@@tetradgroup You remember correctly. Those two right-hand bottom vents apparently are controlled by a separate fan or blower (although I've not seen it). Air comes out of them without the blower (under the seat) spinning. When the blower (under the seat) spins up, the top vents deliver air.
@@duxnlabs yep, there is a small fan that pressurizes the cab in the right hand lower plenum.
How often do you have to replace your tensioner? At work I maintain a t190. Seems for the price of these tensioners,they don't last long. I've been replacing this one at least once a year.
I find it rare that they fail, I think you should get a lot more than a year out of them. Not sure what the issue is.
Sir, I have questions about the Bobcat engine. I am a Bobcat driver. Please help me. The Bobcat engine is leaking oil. It is not from Lagog. Oil is coming out from under the engine..? Thank you
I didn’t know you did request can you do the piston rings on a 773 video. That would be fun to watch! I don’t own one I just want to see you do it
Absolutely, thanks for the suggestion I'll get right on it
I've got a 773 that I can't get the blade into float mode. Any tips or tricks or suggestions?
@@ozarkarky is it manual control or acs machine?
If you wanna send me a couple pictures of the control valve I have a better idea what were dealing with
It's manual foot controls only 😞. There is a float pushbutton on the left joystick but it doesn't down anything. After pressing the operate button the lift & tilt valve light slowly flashes but lift and tilt still works, and no error codes, so I've been using that way as long as I've had it.
Really good video, thanks for the schooling on how to maintain a Bobcat skid steer. God bless.
Thank you sir. I have questions about the Bobcat engine. I am a Bobcat driver. Please help me. The Bobcat engine is leaking engine oil. What is the reason? Thank you again. My name is Jamal from Morocco. Thank you sir ♥️
Why does the part number shown on your new belt not match up to the part number on the link you gave on Amazon?
Good eye! The belt I used was actually for a S160 and although different part number they are almost identical but 1/8 longer. The S160 belt will work on both but the 763 belt would be to tight for the S160. This way I only have to stock 1 belt on my truck for multiple machines.
Had a question ( my belt keeps coming off ? It seems to be off the pump by one groove
Bad tensioner could cause that
Sorry to ask for advice, but my nearest dealer is a few hours away and not great helping by phone. 2013 T650. Personal use only. Ceiling vents are not blowing air. Bottom vents blow on all three fan speeds. Service manual does not show duct routing so I'm stumped as to where to check. Cleaned out blower motor of dust. Seems to spin freely. Guess it's ok since the bottom vents blow air. Ideas? Really appreciate it.
No problem, anything I can do to help. Have you changed your outside filters and your recirculation filter behind the seat? The air flow system is a single plenum so there has to be an air restriction somewhere. There is not a mechanical device that separates air from the top to the bottom vents.
@@tetradgroup Thanks so much for the response. Cleaned the outside filters. Inside filter is missing; cover is present, but no filter. I shot compressed air backwards through the upper vents. Maybe the recirc filter got sucked in. ?
@@duxnlabs it's possible but the filter is really small. You have no air flow on either side of upper vents? I have pulled large rats nest out of the headliners before,
@@tetradgroup I wondered about that. Yuck. Guess I'll start pulling the interior. I REALLY appreciate your taking the time to respond. I enjoy your content a great deal. Very informative!! Thanks. Jay
@@tetradgroup Rats, in the headliner? Were there any live rats in there? If so did they fall on you?
Is it possible to replace the bearings inside the tensioner?
Yes...
Did you use a bobcat OEM belt tensioner? Or did you buy one aftermarket. I see the aftermarket ones are about half the cost.
And I see on bobcats website they break them down you can’t just put new bearings in it and run it?
In this case I used an OEM tensioner. Although some people do not like the aftermarket tensioners I have used them in the past with good luck. I've rebuilt a few tensioners years ago however the price of the individual parts and the time involved to rebuild it in the long run its cheaper just to buy the complete assembly.
@@tetradgroup thank you for the reply. Mines making some noise and needs changed. Gotta decided what to do.
Simple process... Except i can't neither my old one nor my new one compress, even in a vice. Anyone have any suggestions? 🙃 Pretty discouraging to be stuck on a one-bolt job 🙃
Try some WD-40 on the back side, should compress pretty easily in the vice.
@@tetradgroup there's got to be something I'm doing wrong. I tried two different vices I can't get either the old one or the new one to budge. PB blaster all over them nothing is moving at all. 😕
@@StephenfCarman can you physically see a spring in the back side of the tensioner? Not all tensioners are spring loaded.
@@tetradgroup i finally got it to go cranking with all my might on the vice. Soaked it with pb blaster and worked out on the vice. Now I'm fighting with it on the skid. Funny thing is, that it already seems pretty darn tight without the tensioner having even spun past the factory 1:00 position. I gave up on trying to tension it more, and just left it. Gonna start it and see if it's tight enough to work.
I have the same problem. No matter how much I crank down on the tensioner in the machine, that little arrow doesn’t move. Is the spring in the tensioner only there to help you adjust it? The spring doesn’t actually do anything once that bolt is tightened?
Can a bad tentioner cause lose of power ?
If the bearing is siezed it would destroy the belt but that's the only reason I can think would cause low engine power. If you have low hydraulic power the belt could be loose and slipping possibly.
Ok. Thank you for the quick response!!! It is squeeking pretty bad anytime I put it under load or when I push the joy sticks "full throttle."
@@dmadrigal4935 sounds like it's just loose, try to adjust the tensioner and see if that helps. Probably need to replace the belt soon as well.
Thank you ! I'll give it a shot
