Sometimes when brokeoff flush or just proud you can place a nut over the top of it and fill the nut in with weld real good. let it fully cool before trying to remove. The heat swells the bolt and it stays hotter longer than the aluminum But it often cracks the rust loose. The weld will not stick to the aluminum. I had worked in a machine shop a few years and this is a trick a old timer taught me. Other wiseinvest in a good extractor set with left handed drills. If you drill just under the thread size the left hand drill will often back the threads out. If your drill slips a bit and gets into threads then drill it out and retap for a heli cool the right size to restore them. I am sure you have removed it already but maybe my post will help someone out of a bind!
Great job Bob. That coil bolt isn't going to be any fun at all. I would just use a center punch in the broken stud and drill it out. Bad place for a broken bolt. Wishing you good luck with it my friend.
I purchased a new zero turn Husqvarna mower I had 11 hours on it and the bearing locked up and broke the belt. I didn’t know at the time what caused the belt to break, till I started to install the new belt, that when I discovered the bearing failure., None of the the spindles had any grease nor did the front wheel bearings. Husqvarna would not cover the cost. Now I am concerned about the hydraulic motors now no way to check to see if they have oil..
their spindles are made with sealed bearing so pump all the grease you want in and they will not get any in them. Only way to fix them is to knock the bearings out and remove the plasicseal from the sides you want grease to enter. It is a stupid design almost all of these mowers now have.
Actually, I saw a video that would allegedly prove if you pump enough grease in the center, the pressure will push the new grease into the bearings past the thin seal. He used red grease to displace the dark grease originally installed. Also the grease in the center of the spindle keeps any heating down.
My 42 inch has the spindles under the mower which makes them inaccessible without taking the deck off. Minor, but irritating. I didn't use anything on the spindle bolts except WD40 to loosen them.Spend the extra money to get the prethreaded housing...save yourself some pain...
