I have a chance to purchase a used 9400 series Ariens 8-24 at a good price but it has a broken auger gearbox.

 I don't know what the exact damage is, but after some quick research, these parts seem to be in short supply or you have to buy the shaft & the gear as a set ($$$). Is there a place where I can source replacement parts cheaply & does the gear normally slide on & off the rake shaft easily?

Thanks

Not sure about this exact machine or availability but some gear sets can be quite expensive. I was in a shop last Friday and a guy was discussing replacement of an Auger gear set with the owner. He used a bolt instead of a shearpin and ate a newspaper. $294 for the parts without the labor. I heard the dealer tell him the gears are sold in sets because they have to be replaced as a set. That price was for the parts without  replacing the cast iron gear box which was undamaged.Obviously it pays for you to check the price of the parts before buying the machine.

What is the factory model number off the back base of the machine?

 

Can’t tell from the picture if it’s aluminum or cast gearbox but seems to be aluminum.  Ariens is not sourcing any aluminum gearbox parts for the 924 other than as a complete assembly which goes for 190 and up depending on the dealer pricing.  You could get lucky and find some old stock at a dealer. 

 

Chances are good you may just have a sheared pin on the gear and a cheap fix if broken.  Yes, the gear slips off the shaft.

 

There are gears around you can buy if the gear is broken.  The factory recommends changing both the shaft worm and the worm gear as a set (before they stopped sourcing them) I have heard because of wear but not positive.  That would not bother me.  I have purchased a spare gear and would use it.   

Kdez, thanks for the manual, did I miss it or are there no part number lists (descriptions) to go with the numbered diagrams? I see it is available on the Ariens website, but I like to have hard copies for reference.

Thanks

No part numbers in a repair manual.  For part numbers you need a parts exploded view.  To get the right one you'll have to have your factory model number off the back base of your machine..

this is the parts manual link up to 1979. . .http://apache.ariens.com/manuals/PM%2024000.pdf

this page has lots of links for the 924000 series.  I hope it helps and GOOD LUCK!

Kdez - That parts manual does not cover his model.  His is later than those listed in that manual.  That manual covers 70's and 80's.  I think his is very late 80's or early 90's.

GtWtNorth, tough to know what you have.  Ariens made 924xxx models for many years and quite a bunch that look just like yours in 8hp 24inch THAT ARE DIFFERENT.  It's tough to say how similar your machine is with others without you posting your factory numbers.  Kdez has posted the wrong thing twice because he had to guess.

Go to ariens.com and look up your serial and model number on the parts radar.  I would recommend replacing the entire gearbox and to not just try and rebuild it.  Chances are you have other worn parts in there which could cause it to fail again.  If you do decide to rebuild it, look at all the parts in there and if any show signs of wear, replace them as well.  You will have to also replace the oil seals on each side of the auger shaft. Don't forget to replace the oil seal on the shaft that goes to the impeller.  The seals are very thin so be sure not to cut them when you slide them onto the shaft.  If they tear they will leak.  That is why I suggest replacing the entire assembly.  The auger shaft rusts and becomes pitted which makes it very diffucult to replace the oil seals without damaging them.  Let me know how it goes.

The seals can be installed on a buffed out shaft if you use a seal protector or a piece of old micrfiche as a protector.....

Also sometime a better seal can be installed than the unit came with,  A good industrial bearing supply house can fix you up with "very good seals" if you can show them the old one..   

....Just something you may want to try..

Good Luck,

Thanks for all the info guys. I'm sorry to cause problems with these non-specific questions. I saw this machine on sale on Kijiji and just wanted a general idea what Issues I might expect with a gear box repair/replacement for Ariens. I'll try to be more specific in the future. Again, I appreciate all your help.

Cheers
