Troy-Bilt Walk Behind Mower Transmission Fix - Not Belt or Cable! 

I fix my transmission by following your tutorial. When I opened the transmission, there were the 3 parts of the pin! It took me a little over 2 hours. I put a nail and it is working great. Thank you so much, you saved me money by not having to buy a new one!

Incredibly clear explanation, saved a lot of money and trouble by watching this truly excellent video. Thank you!

Man U saved my butt seriously I’ve used this mower like a pro, literally doing 5 big yards a month n a bigger cemetery not to mention I’ve used it like a brush hog, can’t beat it with the Honda motor but short of this issue I’ve got slick front wheels in under two years but man it’s a solider mower for certain! I was at a loss as to what was a miss til I saw this TY!!! 1k fold over!!!

Thanks for this. Just did this repair on my mower yesterday. Only took a couple hours and I only had to remove the bottom case of the transmission once it was off the mower. Saved me some cash!

Great video! I have a Canadian Tire yardworks mower. The Briggs & Stratton motor is a beast but the rest is all from China! The transmission went on it but was under warranty. Going forward if it breaks again I’ll have the confidence to fix it myself. Thanks for your very informative video.

Thank you for the video. My wheels were frozen up with dirt and rust. The cables were shot, too! I attempted to remove the bottom cover of the transmission, but saw that the shaft was turning when I turned the pulley, so I put the screws back in the cover and looked farther to the wheels. I did have a devil of a time removing the right gear behind the wheel. I stripped the T30 screw head. I finally welded a T30 tip to the screw head and was able to remove the screw. I replaced it with a 1/4 x20 Phillips screw. Great explanation of the inner workings of the transmission. Thanks again!

Excellent video! I was thinking of getting rid of my mower, but now I am going to fix it!! I will let you know how it turns out!

Great vid..probably be doing this repair very soon on my Troy-bilt self propelled. My "tractor ain't got no traction" as the old saying goes even though its a walk behind push mower lol.

ive looked all over net for an axle the same axle as mine mtd 50/53 ,your box is identical,now i can fix mine properly as the 3 washers are in the wrong place i put them back wrong,looking at yours ,great vid ,had 2 days messing with mine so far,now to be stripped again,,,,cheers,ev

Handy little tip ,thank you for passing your experience on. [ from Australia]

Did you miss us? :) Nice to see you post again. You explained the details of the procedure very well so if anyone needs this information they have no need to search elsewhere.

Most excellent, detailed video. THANK YOU!!!

Thanks for an excellent video. Clear and to the point.

Good show! I was able to reach in with a pair of box end wrenches and unbolt the end pieces from the deck without removing the wheels. Just have to carefully pry it apart, but no big effort. Thanks for the specs on that pin. I wonder how many hundreds of dollars people have spent on replacing these things over a stupid low grade pin that fails. 😡 Thanks for sharing. 👍🙂

I used a roller pin to replace it... works great ;) and fits perfect. Bought a set of them from Harbor Freight and one of them fits just right

Excellent video. Thank you so much

It would probably be a good idea to heat the drill bit you used with a torch to take the heat tempering out of it to make it tougher to break before you installed it.

Just cracked open my transmission. Pin intact. The retaining spring was broken!!!! Of course, the transmission is obsolete, and no parts available. Off to Ace Hardware to see if I can find a compression spring!!!

Thanks for the video. I've been looking high and low for some time for your explanations. It seems the pros are shy about revealing their dark magic.

Absolutely genius! My pin broke into three pieces just like yours and I replaced it with a hardened nail. We will see how long it holds.

nice video . thank you for sharing your knowledge .

Excellent video! My troy bilt self propelled pushing mower (TB320 21" , 2013) transmission was failed due to a severely worn helical gear. Don't know where this gear is available and couldn't find the part number either.

Thank you for making this video

Do a video on a Murray 626 selr propelled .the trans not engaging when front wheels are on ground

Good information thanks

Thx, and you got that right. They just want you to buy a new transmission.

Great video and very helpful but is the pin 3mm(.118") or is it 1/8" (.125") diameter because those would be common dowel pin sizes and readily available in the length you show. If you install a 3mm pin in a 1/8" hole the shaft hole will rapidly deform and that will cause the pin to fail again soon.

Nice job

Awesome video! Requesting some advice. Checked Google a number of different ways and didn't quite find what I was looking for... With engine in or off, my Troy-Bilt Xp self-propelled pushnower squeaks substantially from the rear axle as you walk it around. I've serviced both wheels via lubing the gears, axle ends, and sleeves and detemined it was the trans from balancing the rear up on a block, spinning the wheels by hand, and hearing the noise come from the transmission. I hope to take the trans apart, identify why it squeaks, flush it and add new fluid. What kind and volume of oil is generally used? Is a permatex silicone gasket bead appropriate for sealing these up? Thank you!!!

Update: Four years later, still going strong!

My problem was just a gob of sealant in gear, but what I need to know is how much ( ounces ) of gear go back in transmission? Thanks

Great video, thank you. How is the drill bit pin holding up?

Great video! I am trying to repair the connection between the drive cable on the 220 and the transmission. The spring is broken and the video does cover how the full transmission connects to the drive cable. Would love to see a view of how everything connects. I cannot find a view. Thanks!

Beautifully done video sir, thanks for posting! I know you don't have this particular mower any more, but it wasn't totally clear to me, what was the original symptom that led you to tear into the transmission in the first place? By the way, McMaster-Carr carries various grades and lengths of stainless steel stock and dowel pins that might work for replacing the old pin. Thanks again!

What did you use as a gasket material? Thanks for the helpful video!

Great video.. My pin broke exactly the same in three equal parts. Its almost like they score them so that they all break exactly like that. Then they can get people unwilling to fix it to replace the entire transmission. Anyway...what oil did you use? I already tossed mine as it was pretty grimy.

I have one of the gears inside my transmission that had a couple of chunks out of it as well as part of the pin missing. I will do the same as you for the pin, but cannot find the gear on line anywhere without having to buy the whole transmission. I have model#12A-466M011. Can you advise please? Thanks for an awesome video!

I am at almost the last step. Where does the tension spring go? It fell off during my breakdown and I didn’t see where it was hooked to

Interesting that it broke into 3 equal sized pieces. Try to keep the burnouts to a minimum... the pin will last longer! =)

I had a.pt cruiser 2007 that the pin on the exhaust cam broke off which knocks.it.out.of time. Odays hardware.in pearland texas had the.pin i needed. Odays.pearland may have this pin on video too.

Awesome video, what gear oil should i use ? Thank you

I have a Troy Built B&S TB240 walk behind. Today the drive lever just went quickly limp. I took the assembly apart that is fixed on the handle. Nothing wrong there. But How in the world do I get the cowl off to see if the cable wire came off, came loose, broke or whatever. I have a feeling the way it snapped something came off under the plastic cowl. But how to get that darned plastic thing off. I can do without the drive although it's going to be hard for the time. 71 here I use it for a few small grades out front. Can you walk me through how to get the cowling off? Thanks so much.

What material did you use In place of the gasket? Or did you just order a gasket?

Can the pin be replaced without removing transmission from the mower?

What did you use for sealant material?

Is it possible to set the transmission vto constantly run , spinning the wheels, without the use of a drive cable.. Say u broke your drive cable. And where you place the drive cable, You can just set it to what the drive cable usually does when it is functioning properly..And when you crank it the wheels start spinning with the belt. If so. Would you know how to do that?

Do you add more gear oil?..and what weight

Any direction in finding a worm gear/ shaft seal for that assembly.

Did you put lubricant after the repair?

The Drive Gears on my lawn mower are attached with a screw and I can't unscrew them. The mower is 13 years old and the screws have never been removed and seem like they are welded on. Any tips on how to remove them. Thanks

how much is a used one on ebay. or is highly unlikely to get the one that fits yours. or could be worn out. not worth all that work to me. guess your mower is worth fixing if it's only a few years old.

Baxrok is there any chance you could reach out to me via email or something. Great video on the Mazda 3’s and my question does involve my 2004 Mazda 3 with the 2.3L Thanks.

You can no longer get the transmission or any of the internal parts so if anything is wrong here you now own a non-self propelled lawn mower unless you can fix it yourself.

Text me how to do a murray selfpropelled

Oil

I hate a diy video that does the stuff. Then freaking points and TELLS someone what to do. This is video not radio. 😂😂😂 I looked for a vid to show me how to remove these things. Although some of it is obvious I prefer a start to finish lesson. Ty for ur time.
