4HP Noma Snowblower Auger Gear Box Repair Part 2/3

[@ccalzeti]

yup, so I figured this out last night after some trial/error. The bushings are mostly round with a flat side that has to line up with the gear case ends when they are pounded in. If not lined up it will tighten and look correct but causes the impeller to not turn easily. This was masked by the fact that I had to clean the grease off to see this. Works great now. Thanks!

dony, that gear you replaced looked like soft material, am i right? if so why? you are the only repair person i watch. i think you are superior.

[@turkmyster99]

Your videos are a great help with fixing a lot of Snowblowers and lawnmowers you are my go to guy for video help. i have the same snowblower going to rebuild the gear box plus i like to change the impeller bearing at the same time i see you just pack it with more grease but i like to replace it. do you happen to know the part # for the bearing thank you i would appreciated any help you can give.

Thanks for a wonderful video I’m a big fan

[@donyboy73]

@harmonicsl Yes I think it is brass or bronze, thank you for the nice comment

[@johnheidmann1616]

Nice careful work and good production quality. Well done.

[@donyboy73]

thanks John

[@legogamer999]

very funny question so should you be able to hold the augers and the impeller freely spins? Mine did that before now it doesn't could it need more grease? I didn't refill it since it seemed okay and the gear was actually fine. It's a 1998-1999 5/22 Craftsman low use 1-2 times per year. It spins as little as it did in the beginning of this video. The first part helped me take it apart.

[@ccalzeti]

Thanks for the great video. I installed a new impeller and the shaft turns fine until I tighten down the screws... it moves very smoothly when the screws are lose but takes a lot of effort to turn after they are tightened down. Is this normal? Just don't want to get back together and have to take apart again. Thanks!

[@goodvids6161]

have a 1989 noma 8hp 24". replaced auger gear. per your video.. putting it back together, with gear housing bolts not completely snugged down the auger shaft turns freely, but when torqued to only 5ft Lbs. the auger shaft turns very hard. took it back apart 6 times, cant find what's binding.

Terrific work! I've been working on an MTD snowthrower that had a cracked auger gear box, and after removing the auger assembly from the overall thrower box, I found four thin, large washers, slightly greased, on the floor. Any ideas? : ) I also have two bushings -- identical. They don't seem to fit anywhere. Ho-hum. Any help would be appreciated!

[@donyboy73]

@AllenTrucks i usually keep it on because i go in and out a lot

[@donyboy73]

@grego10r that should be ok, i usually use a 00 grease

[@donyboy73]

@colbycous01 not quite sure why the collar is there

[@RogueArcher24]

Hey @donyboy73 I have a MTD yard machine that I just swapped out the worm gear like you just did, but my auger has 4 separate blades with spacers. Does it matter how I assemble them back on the bar, or as long as the align with the pin holes and spin without complications, it is fine?

[@donyboy73]

@redbarn713 thanks very much!

[@jimschowe2770]

The little half moon shaped item is a woodruff KEY that fits into a 'keyway' Kind of small correction but say what you mean please.

[@macspud28]

Just to correct you on your use of keyway, what you are calling a keyway is actually a key (woodruff key in this instance). The keyways are the slots cut into the shafts, gear cog and pulley. I regularly hear people wrongly calling keys keyways so it seems to be a common mistake.

[@donyboy73]

+macspud28 yes thanks, I realized that after

[@richardracicot1982]

hey guys does anyone know who makes Duramark brand of snow blower i need parts for it and i cant find any info on this brand i bought it used so i have no paper work its DURAMARK 2 stage 523 with a 5hp tecumseh motor . need help Ottawa Canada thanks

[@donyboy73]

you mean the gear box?

[@Razorrebel1]

A fully threaded shear bolt for application mounted on a axle is bad business. Is it the actual OEM-part?

[@donyboy73]

+Razorrebel1 this is oem bolt on Noma and Murray snowblowers

[@donyboy73]

@MultiKhaz lol, hopefully u got it for free?

[@johnheidmann1616]

The key way is is the machined slot in the shaft, and the woodruff key is the key.

[@donyboy73]

lol, thanks sometimes I get it mixed up
