Each auger has its own shear bolt' Remove and pull the augers off one side at a time. Then you can split the gear box and pull out the broken pto shaft end. The gear box has one side that is a cover. Try the auger on that side first as perhaps you have enough room to play.

Sorry I just don't understand. I removed the shear bolts.but if I'm trying to remove the whole auger shaft why do I need to do that? Should the whole auger pull out of the gear box? Or Does just the auger slide off and a long shaft stays? At the end of each auger there is a bearing that prevents the auger from sliding off. It is what bolts to the blower side wall. Am I supposed to remove that?
Thank you for bearing with me.

The gearbox has a stub shaft coming out of it. Once the shear bolts are removed, the augers are supposed to slide off of the stub. Maybe they need a little persuasion (heat)?

Here is where I am. How do I separate the auger from the gear box???

OKKKKK


NOW: the shaft is a one piece animal from worm gear back to
the PTO shaft carrier bearing? so that is clear to me now I think.

For some reason the shaft sheared directly behind the worm
gear in side the gear case.

This certainly reeks of Swamp Ape Stink because it takes huge
amount of energy to break a piece of round stock normally.
let alone friction welding a shaft assembly.

Its entirely possible to have sheared it off when you backed into the pile
if it was frozen solid as the augers would have stalled at the same time
due to the spur gear being stopped dead and the shear bolts not breaking.

The shear pins are your first line of defense with a snow caster and the only
thing that protects a worm gear driven snow caster like your and mine and
any walk behind unit.

The entire shaft has to be removed and then replaced meaning the worm to spur gear gearbox has
to be split and the entire shaft replaced.
new seals installed as well.


I guess you will have to decide if its worth fooling with and dealing with it.

I cringe every time I use mine as the worm drive gearbox is very expensive for an
RAD excuse for a snow caster.

The greater majority of the newer snow casters do not have the worm gear
driven cross augers that I know of.

Even a new four footer would work well for your cub.

The allied farm king snow casters always seemed pretty reasonable.
Send Ken Sweet a PM through the forum here and ask if he has any snow blowers
left to sell as he was selling them out to get them out of his inventory as he has
much better weather in Kentucky than most.

He ships right from his warehouses too.


I am not trying to spend your money but you have pig in poke there. I am sorry this happened to you.

It looks like the part that broke is Kubota part 70060-00831 which has been superceded by 70060-04038 which is available for $119 from Messicks: Kubota SHAFT, INPUT Part #70060-04038

Well I will continue with the tear down Tommorow after work. If all ends up going well I'll have a working blower for about $150. If it doesn't go well I'll have the experience of trying and maybe next year I'll get a new one. Thank you for the advice everyone.

For what its worth you will have to decide if you really want to just install the
shaft as you will not know if the gear is bad and you may have to replace it
and the bearings too so keep that in mind.

If there are metal chips in the oil etc the bearings are not well just be sure to
use a magnet to see how much metal is in the oil.

At $130. for that short shaft that (from memory) is nothing but about 16" of 1 1/8' shafting with 2 ea 3/8" holes and a keyway cut at ends I'd be looking at a local small machine shop.

The new OEM shaft price may not be unreasonable - looking at the parts drawing posted above by Aaron Z, the shaft has three keyways (2 straight, one Woodruff), a snap ring groove, two centered holes for roll pins and a change in diameter for the last few inches. At the break it looks like hardened material - possibly hardened after machining. A good shop can certainly make a duplicate, but it may not be much cheaper. A new OEM shaft may be quicker to get too.

I agree that the OEM price is reasonable. I think that what you are calling two straight keyways are grease passages so that you can grease the fan and PTO shaft (to allow it to spread the grease across the width of area covered by the fan or the PTO shaft) and the holes are for shearbolts.
