How do you replace the ignition coil on John Deere 38X?

Answer 1

If you mean the STX 38, the ignition coil is underneath the top engine cover. First you must remove the circular screen cover on top of the engine. Remove the three small bolts inside the center cup and then remove the bolts holding down the outer ring. The outer ring and screen should lift right off with little effort. Then remove the bolts on the top-side portion of the engine cover (there are about 7 or 8 of them going around the engine) -one of them holds the oil dipstick tube in place. 3 of them bolt the cover directly down to the engine block. Once all of those are out, the engine shroud (cover) lifts right off and there, in the center of the motor is the ignition coil held down by 2 bolts. A single wire feeds the coil and the spark plug wire exits the coil. Remove the feed wire, remove the plug wire from the plug, unfasten and remove the old coil and replace. Reinstall the cover and upper screen assembly and you're all done. You'll need a 1/4 drive socket set and that's pretty much it. If you take your time, you should be done in 30 minuts or so.

BTW, the gap should be set at 0.010" between the ignition module (coil) and flywheel.
