The two bolt pictured here are what drove me nuts. When i pulled the sole plate, i didn't think anything of it, but two of the bolts were shorter. After i put it back and adjusted the reel I couldn't get the right end of the reel to brush the bottom blade, the reel blades kept catching against the inside curve of the sole plate when they were moving at the back of the reel. I thought about it all last night, was the bearing housing pulled forward by the tension of the intermediate chain when I lowered the reel? I had a look and not possible. So this morning I decided I will replace all the bolts for the sole plate. Looked up the part, and it doesn't match. i think my model is earlier than the one on here. took one of the long bolts to Bunnings and tried the thread sizer there, it was 5/16 x 3/4". Grabbed a pack, got home, they don't fit. I bought UNF thread, must need UNC. We have a local hardware as well so went there, found the uNC and came home. They don't fit either! Whaaat is going on. Went back to the bolts that were in there, and notice they had the tiniest bit of play in them, like 1mm. the sole plate has a tiny bow in it, so I pushed it back wards as hard as I could and locked off the long bolt on the right side. This worked, and i had clearance now, the reel was lightly brushing the bottom blade without hitting the frame. I gave it a back lap and the grind was even, much better. It needs a sharpen, but this will do till I get it all running.
