Holy cow! I can't believe I just sat here and read through all 9 pages of this thread going back over a week! JimP2014, I do believe you now hold the record for the longest single, unpunctuated sentence I have ever read. Up until post #60 I don't believe I saw a single punctuation mark, and few capital letters. #60 was beautiful. It would have gotten you an A+ on a college writing exam. This lack of punctuation makes your posts extremely hard to read because we don't know when you leave one sentence and start another. The reader has to try to figure out what you are saying and decode your post. At a minimum you need to use periods at the end of a sentence, and capital letters for the first word of a sentence. A few appropriately located commas would also help the meaning of what you are writing come through a little better. Rest assured you are NOT the only one that does this, you are just the one that put me over the top and made it necessary for me to call your attention to it. Otherwise I would never be able to sleep tonight.
But, that aside, it seems to me that you are in over your head with this project. I do applaud you for trying, though. It's just a simple mower deck. There are only a few things that can go bad on them. Bearings are probably number 1, belts break, pulleys wear out, bolts break, belt tensioning springs break, bent metal on a bracket, and occasionally a weld will break. Your problem with the belt length is probably because you are trying to put the "too short" ones on without releasing the spring tension on the belt tensioning pulley. The wobbling pulley after you just tightened it is probably because you didn't have the square shoulder on the bolt aligned with the square hole, so once you started using it, the vibration caused the bolt to rotate where the 2 shapes aligned, and then the bolt popped into place, causing it to be loose. It should not be hard to find the case of that wobbling. I can absolutely assure you this: Using duct tape on a mower deck ain't gonna fix it.
Like Rivets, I'm bugging out of this tread. I can't take any more of it. It reminds me of a tech I had working for me years ago when I was a desk-bound tech support guy for all the field techs at a telephone company. Occasionally, while on a customer's site he would call in for help and tell me all the problems he was finding, asking me questions and trying what I suggested, eventually getting to the point that we were just going in circles and nothing was making sense. It finally dawned on me that he wasn't trying what I was suggesting, he just told me he did to get me to move on to another possibility. After half an hour, he'd suddenly be the hero when he would "find" the problem and fix it. Turned out, there never was a problem, he just described symptoms so he could keep me running in circles, hoping to not have to run another service call for a couple of hours. It took me exactly 4 of these calls to catch on to his game. I'm ashamed to admit it took that long.
I wish you good luck. I'm going to bed.
