hello everyone i have an old John deere riding mower a L100 . I use it here to mow a few hours every month . I recently had problems with the steering on there i heard the steering wheel make sounds as i turned the wheel , and when i was turning the wheel it took more turning it for the wheels to turn. until finally the tires wouldnt turn at all. i looked under the mower . i saw a small sprocket about 2 inches long the center of the teeth looked rather worn out. so i took off the sprocket from another john deere mower i have L105 i could NOT get the sprocket to come off on the L100 i was able to remove the sprocket easily from the L105. i took off the large nut under the sprocket that looks about 3/4 " size . is there a small kotter pin holdeing it on ? i also saw that the teeth on this other part that makes contact with the sprocket needs replacement too its shaped like this D the teeth in the middle of that are worn out too.
Parts on both riding mower seem interchangeable the motor on the L105 is bad it needs a camshaft replacement . i pulled the carburator from the L105 to use on the L100
I have some tools to work with , large breaker bars with deep & shallow well sockets . large & small wrenches , smaller rachets . im not sure if that D shaped object has to come off for the sprocket to come off .
I very much appreciate any help it really wears me out pushing a mower all day to mow around the house
thanks again katie (babyangel)
