snowblower auger grease fittings.....

We are working on another snowblower. The auger has only one grease fitting on each side, when you grease the auger with a grease gun the grease only exits near the auger housing but grease never makes it to the inside of the auger where the gearbox is.
There are two shear pins on each side. How come there aren't two grease fittings? Is this a cost saving measure? Does the manufacturer realize that even though grease gets through one side it is not going into the other end? Then when a chunk of ice is hit or a drain cover heaved on the sidewalk from frost heaves, the shear pin is not going to break, what is going to break is the gearbox because the auger will be rusted to the auger shaft!!

See pictures of Mr. Fix-it drilling and tapping out an additional grease fitting hole in order to get grease to the entire shaft.....Mr. Fix-it was lucky enough to get the augers off of the shaft. Once they were removed he had to grind and sand all the rust from both parts, in order for them to spin freely.

That is an awful lot of work , when another grease fitting from the factory that probably would cost pennies for the part and tool setup to drill one additional hole about 6" away from the other one they put in.....what were they thinking?

Do the engineers wake up every morning and say " How can we make the mechanics lives harder today?"

Where was the cost savings here?
