I'll even forgo the 600-grit sanding and see if I can get away with just 400-grit. I noticed that the pump case faces were simply fly cut (typically 0.001" tolerance), so I'm sure my ghetto porcelain tile method would produce as good or better surfaces than the factory finish. Instead of paying $40+ for a granite surface plate or machining a 2" steel disc, I used a scrap piece of 3/8" thick porcelain floor tile and 400-grit wet/dry sandpaper. The parts were well scored and look as bad as the pictures posted earlier by sjsmith and idakiteman:Īfter much self debate on sending them to a machine shop or DIY, I decided to try the cheapest method possible and sand them myself. So I finally took the K46AC out last weekend and took some "before" photos. The K46AC would whine all the time regardless of the temperature. It would drive OK when it was well below freezing, but when I ran it during the last early spring snowstorm, I had trouble reversing up a shallow driveway after snowblowing for 30 minutes with the snowblower attachment and 50 lbs of ballast. I did a half season of snowblowing on my L130 (370 hours) with the new oil. My oil-change-only method with 5W50 synthetic didn't work very well.
