How to Install Transmission Drive Belt TroyBilt Bronco Tractor 

The 22MM Crow Foot fit so I bought the metric kit for around $27 more likely to use them in future. My nut came off easily so grinding an old wrench shorter and crow baring might have worked. I used an old bike cable and scrap piece of wood as handle to pulled spring worked nicely. Thank you very much for video it wasn't difficult and I am back on the road. A real MTD Kelvar belt was $18 on Ebay seems worth the few extra dollars the other belt still looked serviceable that is still half price of normal retail. Didn't even know Crow Feet Wrenches existed! The same PT Performance brand is cheaper on Ebay than Sturdevant's if you watch the video in advance you can save a few more bucks.

I’ve watched 10+ videos explaining how to do this and yours is the only one that makes sense and can see what’s going on! Thank you!

I like watching your videos, even if it's not my type of mower, I might see a trick or two I can use fixing mine

Thanks for the idea of using a crows foot and extension with using a breaker bar for taking off the trans pulley

Thank you for your great videos. I found it is helpful to take the clip of of the lift rod that goes over the pully, right side and you can slide it out of the frame bushing and you can get straight on the pulley nut. :)

This is so detailed and excellent.

Love your video Jack! Your website too!

Best instructional video I've seen so far to replace the upper transmission drive belt on a Troy Built Bronco. Great work and explanation. 👍

I have a troy built bronco and I changed the belts on iti did not do that short belt cause I thought that would be the way to change that belt so that's what I will do

Do you happen to have the numbers of the belts thank you

Awesome video 👍🏼.

Regarding that ornery spring, I use a loop of #80 weedeater line that I run thru a handle that I made out of a small block of scrap wood. I drilled a hole in the handle & then tied a double knot on the line ends after inserting them thru said hole. The loop grabs the curved spring end. When I get the spring in place, I cut the line (which is now pinched) to remove it. Yes, I have to remake the line/loop next time I need to perform this task but that's not very often. Your hook is better but sometimes one has to improvise. Thanks for the very well filmed & communicated video!

Hello can you help me I got a bronco 42 inch if I lift it on Jack stands n place on reverse tires turn ,but when I place them on the ground tires don't turn ?

Great video. My clutch is on the right but pulleys look the same. Mine popped off the idler. What would cause that?

Thanks for an excellent video; especially in getting the light exposure in an unlit space. I ordered a spring tool after watching this video. I own an older vintage Troy Bilt (2005) that has served me faithfully. Years ago I paid a local shop $150 to "replace all the belts". I have a very small mowing area and use the tractor for towing a small yard trailer; a year later I discovered that the belt for the blades had been the replaced BUT the drive belts were almost in pieces (multiple deep cracks); the "mechanic" had obviously given up in replacing that belt but still charged me for the entire job! Lesson: watch videos like this and DIY. BTW, at least on my mower, there is a frame bolt on the left rear of the mower which, when loosened allows the pulley on that side to be moved enough to slide a belt over it. Just FYI.

Is it a lot of trouble to take the body off?

Tony how about going over replaceing long drive belt , I'm haveing a little trouble

THANK YOU!!! this video was extremely helpful! I borrowed a crows foot wrench from a neighbor (he didnt have 7/8 but the 22mm worked!) I also didnt use a hook tool. I used an old dog tie-out cable and looped around the spring hook and pulled the spring through the hole.

Wheredidyou get that spring pullerfrom an how much do they cost

Got a craftsman lt1500 basically a mtd 42 inch . Just replaced the upper transmission belt and now it won't go fast at all. Its like speed 2 and the clutch doesn't seem to go all the way back now. Any suggestions? I've been all up on the pulleys and don't see any remnants from the old belt that shredded off. I'm lost at this point. Thanks in advance!

Is not there another spring for tension on this belt near the mid pulleys?

Excellent presentation on how to install transmission drive belts on TroyBilt Bronco

i have a troy-built bronco, i had to swap out both upper and lower last year because it just stopped moving. it ran better but i still had to push the gas almost all the way to the floor before it will move and the longer belt feels as loose as the original one i took off. i really want to get this back to par. any ideas?

Dumb question. Are you from Maryland?

Oh yes those springs is strong pressure for belt tension

You could take the body off the back which I had to when one of the flat idler pulleys top nut that was not accessible. Way easier to access trans belt but a hassle. From a 2004 Z809K Troy Bilt owner.

Great video & thank you! What I do is take the entire upper frame off. About a 30 minute job. Makes belt changing a cinch.

Thanks 👍

Good video. You reminded me of a friend I had. Missing his left hand from birth due to an anti nausea medication his mother took during her pregnancy. It was amazing how he had compensated for this. So much so I got to where I didn’t even consider it when we were working, hunting, fishing or whatever. Oh yes, our work, we were both police officers and counted on each other to go home to our family at night. We both retired unscathed from those tried to scathe us. 😂

Excellent showing..I applaud you sincerely.. Thanks 4 ur skillfully knowledge..

I'm working a lower drive belt on the Bronco, that seems to be stuck in drive and reverse. I had to replace the jam nut that was missing. The only way to stop the tractor is to turn the ignition off. I know the part # is 954-0467, but that belt seems to be too tight and will not become loose and fear that is the issue. The other # is 954-0467A. I hope that one is at least 90.8 inches. I had hoped that you were going to do both belts to see the routing. There are no schematics under under the frame as other tractors have. As for the spring though, I use a long electrical wire to loop around.

Thank you for this very instructional video. Looks like a quick trip to the auto-parts store for that crow's foot is in order. Anything to save headaches. Mine popped off yesterday evening right at dark as I was driving it to put it away in the shed, figured it was going to be an ordeal. Not now, though, that I know how to approach it.

You've GOTTA be a Maryland or Pennsylvania native! Am I close?

I repair mowers myself all day long and the flashlight that I use is a Milwaukee it’s the greatest flashlight that I’ve ever seen it’s expensive but you’ll really love it. There’s never been a time that I couldn’t stick it and adjust it to right where I want it it cost like $200 without the battery but it’s a good one.

The Drive belt always been jumping off. On the Craftsman T-140 > IDK WHY? OR HOW IT DOES THIS? Unless the belt guild is to wide ? Idk how it keeps jumping off? or the idler pulley arm is BENT? IDK? YOUR RIGHT! The dam idler arm spring is very a strong spring> i use the rope method > but i'am going to make a tool like your. but longer like you said. THANKS FOR THE HELP! > If any one know what this problem is? PLEASE COMMENT! If i fine a way to fix it? i will leave a comment here. Right now! I'am thinking of putting a higher idler pulley on it to keep it from jumping off. THE SAME SIZE BUT TALLER > I think this will fix it. Do away with the belt guide when you put the taller pulley on. So it want chew up the belt > ( OR ) Close up the belt guide where it can't jump out. BUT IT WILL WEAR ON THE BELT (OR) it could be the idler pulley arm is bent? Making it jump off? idk yet. 1 of the 3 bound to work

Thanks man !! Very helpful!!!

Nice work,,most people with 2 hands wont do this,,you da man,,good tips ,Crip in Ohio

Thank you soo much, this is exactly what I needed to replace my belt. Clear and Straightforward directions.

Wow excellent video! Just found your channel. I just got a troy bilt tractor off Facebook for 200 bucks. It was garage kept, engine surged etc...I hope i wasn't ripped off. The tractor won't start now. I charged the battery, it turns over but won't stay running. The guy I bought it from had it running when I picked it up. I could hear it surging while it was running. It looks like an older troy bilt. I checked the filters all new, spark plugs new, the guy I bought it from said I might have to spray some fluid to get it running..any help would be appreciated. Great channel and will donate 👍

👀👌💯

You did a good job of explaining that, especially for guys that don’t have any clue about mechanical side of things. Well done

Great video, thank you. I couldn't find my hook tool, so I used strong twine and left it tied on to reinstall after.

Thank you so much!

After watching this and having problems with springs, I've made a hook from an old washing machine tub stabiliser bar and a piece of thick dowel was pre threaded with washers so easy to make.

Great Video. Thanks for being so through.

Thank you so much you were very helpful.

How about some part #s. Model # of mower? I have a 2018ish bronco…I bought used, all the labels are missing so I’m having trouble getting the right part #s but my mower looks just like that one and my problem is it goes so much slower In forward than reverse🤷‍♂️..please help😂

Thanks brother, nice video and a lot of help to me.

Great video! Thanks!

Thank you!! This is the best!

Hello friend, i replaced both belts and now my mower wont brake in gear. Its the same exact one as in the video. It also seems as if the pedal wont go down all the way. Any idea why?

Great video! You saved me a lot of aggravation!
