    Belt keeps popping off.

    I'll send a better picture .. the picture I originally posted, was taken when the thing was partially disassembled. Belt LOOKS loose cus spring(s) etc. were detached. When assembled everything is exactly as it was out of the box 12 years ago. About 6 years ago I turned this thing into a...

    Belt keeps popping off.

    I've replaced the damaged anti-rotate bracket and new transmission and all the brackets holding the three pulleys. The two main pulleys were always in perfect alignment. But the smaller idiler pulley was always (before the damage occured) slightly tilted a couple degrees. I assembled with...

    Belt keeps popping off.

    Finally got around to where I could see the problem. Part #50 (anti-rotate bracket) was cracked and only being held together by a thread. It wasn't bent but actually cracked at the bend and became more of a hinge than a bracket. So it didn't fully break appart but flexed enough to allow the...

    Belt keeps popping off.

    Yeah I know .. The spring in the picture was disconnected. It's not an issue. I've changed belts and had this thing apart several times over the years. This current problem is something different and new from anything I've experienced in the last 8 or so years I've been using it. For...

    Belt keeps popping off.

    Thanks very much for all the detailed replies. I'm going to take the tractor apart while waiting for the new belt to arrive and will post some pictures with hopefully better views of the system. But some comments here first: To quote ILENGINE: "I suspect the anti rotate bracket has come off...

    Belt keeps popping off.

    Thanks everyone. I think "StarTech" has the best grasp of this problem. Yeah, the "model number" is strange when trying to get info. The printed manual that came with the thing is a 28881. The actual model of the tractor from the chassis label is 247.288810, Serial 1C301B80276, and was...

    Belt keeps popping off.

    Craftsman 2011 - 247.28881 7 speed Shift-on-the-Go lawn tractor. What would cause the smaller vari-speed belt to instantly pop off when engaging clutch? Could this be caused by a miss-adjusted part of the linkage? The user manual does not have any instructions for brake or clutch...

    Head Lights not working

    Star Tech ... thanks. Looks like what I have is possibly an early model (2011) with the last digit omitted. It has to be your #1 diagram for the 88810 schem. The others are different, (one is a 19 HP as opposed to my 17.5 HP, and the wiring is different on the other two. Can't thank you...

    Head Lights not working

    Have a 2011/12 Sears LT1500. Model 247.28881 Built by MTD. Some time ago both headlights just stopped working. Also noticed at that time tractor was having some trouble turning over. Always started but just barely. I load tested the battery and it was very weak. Bought a new battery and...

    Craftsman Rider dies

    See if the fuel line from the gas tank to the carb has a "bend" in it where the line loops lower than the carb for a few inches. Like the line starts high at gas tank then loops down LOWER than the carb and then back UP to the carb. IF you have a PARTIAL gas flow problem somewhere (like the...

    Tecumseh OHH50-68023J w/ 640340 carb problem.

    Makes no difference. Once it stalls and fuel starts flowing out profusely, it doesn't stop. It flows whether or not the cap is loose or removed during or after it starts leaking, with or without the original unmodified cap or with with cap with the hole. And as I said this last time I did...

    Tecumseh OHH50-68023J w/ 640340 carb problem.

    Yeah, I do regular maint. on all my stuff. Cars, trucks, tractors, appliances etc. Enjoying retired life on a mountain top in the middle of a forest where I do daily battle with chipmonks, mice and squirrels. They get into everything so keeping the machinery clear of acorns etc. is part of my...

    Tecumseh OHH50-68023J w/ 640340 carb problem.

    Ah thanks guys. I thought about that, and DID notice once in a while while the thing was stored for a while with some gas in the tank that when the temperature changed over night from very cold to hot (been having extreme weird weather here lately) when I cracked the gas cap to add gas I could...
