Is there a way to tell if the bolts are shear bolts or just regular bolts someone stuck in?

I went out and tried turning the impeller by hand on my 928 (with the ignition switch off) before suggesting timh310 try it. It turns, but not easily and I did worry about getting my hand stuck in there. Yes, maybe using a stick would be a better idea and you could come from the front, which gives a better view of the auger anyway.

Glad you found the problem and that it was something easily corrected. As for the lube in the auger gearbox, check it and if it’s ok or only a bit low, leave it until you find out what to use as borat advised.

However, you might find there’s very little lube in the gearbox and/or you might not be able to find out what lube was recommended. There is a solution.

Newer machines are going to liquid grease rather than gear oil. The difference between grease and oil is that grease also contains a thickener such as lithium compounds, molybdenum compounds, or PTFE’s (Teflon). All grease contains an oil base, so a good gear oil won’t damage seals that a low temperature liquid grease won’t damage. In a pinch you can use a synthetic 75w-90 gear oil. A synthetic gear oil will have excellent low temperature properties and higher shear strength that any conventional gear oil. Using it even if you don’t know if it’s the right lube is much better than having little or no lube in the gearbox, which is not uncommon on old machines. If you do find the gearbox is nearly dry and you add gear oil, the gearbox will likely leak oil for a while until the gaskets swell up. Just put something under the gearbox to keep it from messing your garage floor. Also, keep an eye on the level.
