The wheel of my lawnmower keeps falling off;it appears that the carriage bolt doesnt seem to grip the wheel.Can anyone help me with a solution?
Most lawnmowers have body bolts that have a larger diameter through the wheel to act as an axle and a smaller diameter in the threaded area to go through the mounting bracket. There should be a lock washer and nut or a lock nut on the threaded potion to draw the shoulder of the larger diameter portion tight to the bracket without pinching the wheel so it still turns freely. Most wheels have a bushing to ride on the axle. If you have a high quality mower, the wheel may have a bearing assembly that is worn out. That would cause big time wheel wobble. Solution-replace the wheel. It's near impossible to find these bolts at a hardware store. You can find them online or at a lawnmower shop. Do a web search for your mower brand model and you can probably find a parts list if you don't have your manual.
Drill a hole in the center of the wheel a little bigger than what is there. Get a brass bushing and insert it. Make sure the hole you drill will incorporate the outside diameter of the brass bushing. This will last a lot longer and also make the wheel a lot more stable. Then re-insert the carriage bolt, this should take care of your problem and the wheels will last a lot longer. The plastic wears out way to fast and this is an easy and very sturdy fix.
