MTD snow blower auger gear case repair how to YardMan rescued from the curb!

Yeah yeah it's been a while..
I found another non deserving piece of scrap at the curb with a minor issue 2 miles from home. A 22 year old YardMan snowblower with a broken auger gear case.
An issue that could have been avoided if correct shear bolts were used.
The video is long.. but the repair should take about the same time, I did not want to leave out any detail as it only makes complaints..
Parts used:
918-0123A housing left
918-0124A housing right
710-0890 shear bolt kit 2014 and before
Permatex Ultra Grey RTV sealant
Valvoline GL-4 gear lube
By the way mark the augers before removing them, at the end you will notice they are on the wrong sides, had to switch sides the next day. Thanks to a keen viewer..;0.
Thanks for watching!

Excellent video - My mother in-law is visiting in a couple of weeks while she is here I will spend a few days hiding out in the garage taking my snowblower apart to put some Lithium grease or anti-seize on the auger shafts.

[@gerryplante2651]

I pulled in a chunk of asphalt hidden under the snow at the end of the driveway. I ordered a new auger to replace the broken one. I poured a coffee before I started and decided to check youtube for pointers. I looked at a few but yours was the best done and most helpful to me. I have fixed a lot of my equipment and am pretty good at, but there is always something more to learn and you were a big help. It helped me avoid going about it the wrong way. AND......it was 12 degrees in the garage/shop so watching your video was a good reason to come in the house and warm up. Thanks!!!

[@MowersNBlowers]

Augers are backwards! Time to split it up again!

What impressed me was the ease it came apart ,all bits and bobs were found exactly where they were dropped .Not like one of my projects for sure . I need a exploded view of the parts to show the order in rebuild - great mechanical knowledge ,great vid

[@donhart3782]

Good job on the video, clear descriptions and part explanations and good camera work. The finished product looked like it was running as good as new. I would just like to point out a few things I noticed. Pre assembly lubrication applies to all machinery. Always remember to pre-lube all gears, bearings, bushings and seals with the manufacturers recommended lube. Using gear oil in the gear case can be risky unless you make sure that you are using either G4 manual trans rated gear oil or G5 that is rated for yellow metals. This gearbox works like a differential in a car but the brass gear is a lot softer than a steel gear and can actually be damaged by using gear oil with active sulphur. Improper lube can actually eat away at the brass gear, dramatically increasing the wear rate. Some manufacturers recommend low temp grease, some 75-90W inactive sulphur gear oil and some even recommend 30W motor oil and 5W30 motor oil. It's always best to get the recommended lube for the type of gears, bushings, bearings and seals in your machine. If you can't determine the proper lube, 00 grease is the best compromise. Marine, outboard motor lower unit oil is brass friendly as well and would be the next best compromise. Judging by the pre-load on your gears, the brass gear is worn and may have to be replaced soon. Replace using the exact amount of manufacturers recommended lube. Spread some lube on the gears, bearings or bushings and seals before they are placed into the housing during assembly. Fill housing with remaining measured amount of lube either before assy. if no port(put lube in one half of housing before sliding other half down shaft and sealing) or after assy. through fill port.

Have the 5.5hp yardman since 1996 it is a beast. 1 pull starts every time

[@Whatever-od7zi]

Nice work. My neighbor gave me his early this spring because the augers stopped turning. He ruled out everything else and said the gear box is bad. I'm guessing the worm gear broke on it; I have yet to take it apart but this has been a helpful video. Thanks!

[@Terry3Gs]

Great video ... found it while searching for a understanding of my situation from a few days ago. I hit a brick hidden in the snow I thought I had gotten out of the way & it got caught under my auger blade & after it killed the auger flywheel drivebelt I was able to replace it on my own. BUT my engine & drive system runs fine on it still .. BUT as soon as I go to engage the augers it totally stops & seems something in the augers system is seized & wont allow for it to be moved at all. Im now in the process of waiting to hear back from a local shop to come look at it/do the work on it as its out of my ability to do. Again ... awesome job on the video & subbed for future references/content !! :)

[@builtyankeegirl]

00 grease is a must for long life, it's specially made to not freeze up and keeps gears coated.

[@wayneo1486]

good video, did the same job on a 40in. cub cadet blower attachment on yard tractor. After first start, discovered augers were reversed the same as yours. Can,t get snow to fan that-a-way.

[@lookeywho1287]

Reverse the augers

[@MattPiekarsky]

Something looks off at the end when you run the auger. The auger blades are driving to the outside. Wouldn't you want them to pull snow to the inside to feed the impeller?

You scared the heck outta me when you leaned over to check that the augers were turning and the cord from your hoody was dangling there. Anyway, thanks for the video. I needed info on how to grease/lube the gearbox.

[@benmichael1494]

Very well done ✅

[@thekingsilverado3266]

These newer snow blowers around here in the north east the cables break and if that doesn't happen first the things rust in half totally rust out bearings too all of em. The pivot bolts seem to seize up as well. All really cheap tin foil metals.

[@paulbrown8370]

Nice job. I had to see this, I have a customer who said his Auger is turning but not the impeller shaft. So I think it could be the gears inside the case. It is an old Sears Craftsman he says, very old. I guess I will find out soon though. Nice video, but I would have made a real gasket for the case when I put it together and got a good bolt to fit in the top to plug it up. I know most of them have a threaded bolt in the top filler hole. Thanks for a lot of info.

[@MowersNBlowers]

If the impeller shaft doesnt turn, it's impossible for the augers to since the augers are powered by the impeller shaft.

[@paulbrown8370]

True, he may have thing backwards, but I told him it would be somewhat expensive, so he decided not to bother putting the money into it now.

[@logigustafsson]

Nice video there! Yet you scared me when you bent down to see if the augers were running, with the lace from your hoodie dangling near the housing. It may have been further than it seemed, but I dare claim that loose strings/ belts or even long hair (not an issue for you though, lol) have actually been causes of deaths and serious injuries, and should be kept away from revolving machinery at all cost.. Subscribed due to this video, excited to see what else you have in store! Best wishes!

Logi Gustafsson thanks

[@kenhilson786]

Mtd specifies a special 00 grease for those gear boxes. Friend of mine used regular grease and paid the price. This time he got the mtd part numbered grease.

[@MrVile-bz9fw]

Take a hard look at the augers while its running . Like I did one time , I think you did the same. that is I'm pretty sure you put the augers on the wrong side. Check it? My auger is on a tractor and oh boy it was not fun to realize i got them reversed when I went out in the 1st heavy snow & had to stop, go back in the shp and do a quickie switch of them. good luck , nice job

[@Broncocarl92]

Yeah I just looked and you are right! I never thought about that.. but like I said in the video first time for that job. At least still warm here and it won't take long so I will flip them around today. Thanks a mil.

I see the snow blades are traveling in the wrong direction instead of pulling the snow into the auger blade, they are pushing the snow outward.

carl cappy yes I realize that from another viewer and put it in the video description. Thanks for the comment.

My shear bolts are stuck too..and I got a DB jammed up in there! A cat or a coon pancake left by the plow truck in the piles at the end of drive. Smells terrible, luckily I have a respirator but I cant be messing around too long.. will try an air hammer. Hoping to unwind it. They are 3/8 bolts that were put in at some point when the shear bolts broke.

[@victoryfirst2878]

My dad has a Troy-Bilt snow blower. He goes through shear bolts like candy. Got him a box of 100 bolts and nuts just five years ago. Hi is down to about thirty. When you live on a farmeit, you go through lots of shear bolts. Cause of cow patties freezing and they are like bombs. The person who owner the yard-man used the wrong bolt type. Bet you it is hardened bolt. I have a yard-man machine a neighbor gave me for helping him out over the years. Mine has tracks and they are like new. Bet you that the new track material will never compare to what I have and the machine is from the late 70's or early 80's. Ten h. p. Tecumseh snow engine. Manual say the engine will surie with really low oil level. Bet you they will never write that fact about the new machines. You will lose your machine i bet. I really like mine. Would never sell or get rid of it. Good day too.

[@Broncocarl92]

The person who owned it before me did use shear bolts, but they were for a different diameter auger shaft and the shear points were not where they were supposed to be, did not fail when they were supposed to. Not all shear bolts are created equal LOL. I just used it tonight for the first time this season, started on first pull of the rope after sitting all summer. It's a beast! Thanks for the comment and the interesting story!

[@victoryfirst2878]

@@Broncocarl92 I can tell you that just about any engine that is put away correctly will start in a pull or two. I really love the old snow machines. You can tweak the engine for more power within reason. The shear pins can be calculated at when they shear by using a formula on engineering toolbox. Do not remember the exact web--site. But keep on working and using elderly machines. Good day too.

[@snappingbear]

It looked like you could have removed the auger without taking everything apart. The drive shaft just slipped away from the gear box. In my case, I just want to remove the auger assembly because an extension cord caught got between the side flange and the end of the auger shaft. It is jam so tight I can't pull it out. It actually bent the flange out. Wouldn't it be easier to open the gear box and remove the drive shaft to get just the auger out?

[@Broncocarl92]

You could try heating it to 400ﾟ in the oven. Leave shaft in snow. Should slide together.

[@ChildrensStorytimeCorner]

You would have been better off using thicker bearing grease and packed some in and squeezed a tube in also. Reason is all these gear boxes leak over time and the liquid gear oil is just another trap that will get you some years later!

Did you ever find out how to get the bearing off I am In the same situation and cannot get the anger out of the housing because of the Bering

[@falcongro]

@@anthonygrace562 yea i did, gave it a nice little wack...add some wd40 or something though ...use a mallet and a socket that will fit around the outside of the bearing

[@anthonygrace562]

Ok I’ll give it a try. The bearing needs to come off to get the auger out of the housing correct? Did you smack it towards the auger then just slide it off when it broke loose? Or did you hit it towards the end it’s already close to that won’t go through the housing? Sorry about the questions i appreciate the feedback though.

[@falcongro]

@@anthonygrace562 when you put that socket around the bearing, hit that auger axel real hard..use a mallet though. it will punch through, so the whole auger will drop down..then the bearing will just come out hopefully.. ( if bearing is stuck in there ) do this --> after the auger and gear box assembly fall throughs turn it upside down and then you would be able to knock the bearing out . just incase you didnt know the bearing comes out from the top..

[@tazmun]

Only one niggle, and it’s not your fault because there is apparently documentation out there that indicates gear oil is OK. My experience working on Sears equipment which is basically the same thing as you had there is that The seals on the snowblowers gearbox are not designed to hold in oil. Reference the seal on the input shaft and look how huge that thing is compared to the shaft slopping all around there. Sears provided us techs on the road with a little cups of white lithium type grease in a paste that we would fill up the gearbox as much as we could.

[@Broncocarl92]

Interesting.. hasn't leaked out yet and it's been a few seasons since this was made.

[@tazmun]

@@Broncocarl92 I’m surprised, maybe you didn’t put much in. Take a mirror and the light and look for that input shaft goes in, you can see air between the shaft and the seal. At first I thought I had wrong parts but they’re all screwy like this. I guess in the environment it’s used there’s no heat developed most likely thus there’s no pressure. The seals on the output shaft are better but still appear to be mainly something that will only work for basically dust shields.
