I'm not talking about the 'ends', I'm describing the middle where the snow collects on its delivery to the fan. The 2 pictures are from 2 different random snow blowers that I found pictures of. Here are some more. All I've ever seen in the field is the collector section at the center of the auger frame is in phase. The 'ends' are out of phase generally because they are a different length. Check out the schematic, the augers meet in the center while the ends are 180 degrees out.
SeaRay's don't seen to be positioned that way. Snowblowers that are 180 degrees out at the CENTER usually have 2 rake straps joining them to shovel snow into the fan. These are the end drive type with a roller chain drive. Can't do that with a center drive gearbox.
He said the thing seems out of balance. Yeah, the shaft collars are not aligned per the gearbox float, but the parts books show spacers installed to take out the slop.
That's why I'm a plow guy. No need to worry about pea gravel, a twisted neck, a serpentine driveway path, or shear pins. My engine only turns 15,000 times to clear my drive. Any frozen dog poo gets pushed aside. No need to clean it out of a fan or chute.
