Colby Smith: Donyboy73, thanks for all the great videos. I have used your tutorials on all my chainsaw, lawnmower and snowblower fixes. Your videos are very informative and you have saved me a lot of money as well as taught me a lot. I hate having to get someone else to fix something for me if I can learn to do it myself.
I am having a bit of a challenge diagnosing my latest problem and hopefully you can help me out or point me to a video you may already have (that I have missed). I have a 27" Murray Snowblower and today while using it, I noticed that I seemed to have a lack of power. Sometimes while in 1st or 2nd gear, the snowblower would not propel itself. I later checked the idler pulley and it appeared to be in good shape and tight enough. I then heard a scraping noise from inside the housing. I determined that the augers were still spinning, however, the left side of the auger blade (if you were standing at the controls) was now scraping the side of the housing assembly and gouging the metal. I removed the shear pin to stop that side of the auger from spinning temporarily until I can figure this out. The shear pin was in tact, although it had a slight bend in it. Once the shear pin was removed, the hole in the auger blade would no longer line up with the shear pin hole in the shaft. It appears to have misaligned by 1/4". There is a 1/4" gap between the auger blade and the bushing on the housing assembly, however, I cannot slide the blade to align the holes because the end of the blade is pushing against the housing assembly.
I can't understand why the auger blade just began doing this. Is it possible the the gearbox and/or impeller has misaligned and is now on an angle causing the scraping? If you could provide any guidance on how to troubleshoot this, it would be greatly appreciated. Another Nova Scotia winter snowfall is coming soon and I want to be ready. Thanks again Donyboy!
Antonio Aguilera: hi..i am looking for a mtd 26" auger housing 684-0040D
John Bird: Hi Dony, I could use some help. I have a 42" John Deere snowblower attachment for my riding mower. This seems to be nearly the same type of system but there's one thing I couldnt understand from your video. I removed the pulley on the back of the snowblower housing but I am not sure how to detach the worm gear drive/shaft/impeller from the housing. also, not sure I can get the 2 pins out that are attached to the gear drive shaft where it meets the impeller. any suggestions?
Basher: Thanks Donyboy73 Cost me ~$35 in parts to fix. Our excellent local small engine shop needed $250 + parts.
Youtube and folks like you are an incredibly valuable resource! Thanks Again
Buddy B: Hello it's me again. What would cause a snow blower to spray gas out of the primer bulb, the carburator the drain valve under the bowl and the tiny little hole that's on the side of the carb itself.?
Michael LeFave: does anyone know if a Ryobi 10hp 28 augur front will fit on a yardman 8.5hp 26inch front. it looks exactly the same, but the motor is obviously slightly less powerful and the mouth is a few inches bigger. It surprisingly looks like it could work, but before I rip it appart to find nothing lines up has anyone else tried this. the yardman is mine, in good condition but it stripped the gearbox bad, steal shaft and the gear. the Ryobi I just picked up at a scrap yard for 12 bucks. broken gas tank, no handles, probably a bad engine.
Michael Rumak: Rebuilding a very similar blower mtd 29 inch and have looked at the diagram for the blower it only calls for one washer by the gear box and in my parts box i only have 4. Am i missing something?
Jonathan Dignam: Donnyboy, great video as always. Very detailed. Do I have to maintain the gear case in anyway? Do I have to remove the grease plug and add grease? I have not lubed the MTD snowblower. When I remove the shear bolts what kind of oil do I put in there. There is no nipple for a grease gun anywhere. Thanks
Mark Cramer: what would cause the impeller shaft to move back and forth ? so much so that the impeller blades scrape the back of the auger housing and the auger pulley hits the engine frame ? Auger Pulley looks like it woobles a bit too?
John Romanoff: Thanks for the video. I got the gear box replaced, but now I can't get the impeller/auger assembly back in the housing. The shaft for the impeller won't fit into the bearing. I've greased it, but I don't want to start pounding on the thing now that I fixed it!
Rob Kennedy: I am having trouble pulling or separating the Auger and impeller from the bearing! Any advice?
lanp2502: First, thanks for this very helpful video! My problem is very similar to the one in the video, except that my gear is not snapped, but very worn. Is there a way to replace only the gear? It seems to be pressed on the shaft.
Bruce Bastarache: Can you explain how to determine RH vs LH and in/out on the auger spirals need to be in the case that they get mixed up?
Dave leaf: do you know what kind of fluids or gear lube goes inside the auger gear box?
Enrique Benedicto: Salut Don,
I think I've detected a bit of a French Canadian accent... but I'm going to go ahead and ask my question in English, in case I'm wrong... :)
I have one of those tractor mounted snow thrower from MTD (model OEM-190-823).
My auger gear seems all messed up. I'd like to take the assembly out WITHOUT taking the whole Impeller assembly out in the process. There are a couple of spirol pins on the shaft that goes through the Impeller. Is there a way to remove those pins easily without having to pull the Impeller and/or snow housing assembly?
If I need to pull everything out... this may just be too much work for me. If I could, however, remove those pins... then the job (with your videos) seems pretty easy.
Any help would be appreciated.
P.S. I'm using the user's manual for part names... I have no clue what I'm talking about :)
Jon Jones: Thanks... bought an old one the other day, and the gearbox blew after an hour. With your video and $85, I'm running again
Lisa Iobst: Thank you so much. I fixed my snow blower yesterday and today we had a foot of snow and worked great! Thanks to your great videos!
ryanarey79: Great video
Pejones95: Appreciate the video. I am working on my 2005 MTD Pro, the bearing in the housing behind the impeller did not want to come off the shaft. I used a gear puller to get it off. Should that actually just slide out? - I am afraid I stripped the threads inside the impeller shaft when I did it. Also can you recommend a site to purchase parts?
