Heat up the wheel with a torch, somewhere near 200-degrees (fahrenheit) and using heat resistant gloves, pull the reluctor wheel off of the crankshaft. The reluctor wheel with Goodson’s jig in place. Installation is just as simple. Check for any burrs on the wheel or mating surfaces.
Can you change the Reluctor wheel on a LS?
The reluctor wheels on LS cranks are pressed on and there are a few tricks to getting the old one off and the new one on without causing any damage. That’s right, you can’t just hammer a new one onto your crank and call it a day.
What is 24x crank Reluctor?
The crankshaft reluctor has 24 unique pulses per 360 degrees of engine rotation that the Gen 3 PCM interprets to know engine position. This is where the “24x” terminology/saying comes from. The camshaft reluctor provides what is called the “1x” signal because it is either on or off for 360 degrees of engine rotation.
What is a 58x Reluctor wheel?
GM LS engines feature a toothed reluctor wheel (also called a tone wheel or tone ring), which is press-fit onto the rear of the crankshaft. This toothed wheel is used by the crankshaft position sensor for ignition timing.
How do you remove a Reluctor wheel?
Proper position of the wheel is essential. To avoid bending or distorting the reluctor wheel, DO NOT use a puller when removing it. We recommend heating the wheel with a torch to about 200ºF. Like all metal, the wheel will expand and you should be able to slip it off easily.
Can a Reluctor ring go bad?
Even tiny fluctuations in thermal expansion, or vibrations themselves, can weaken and break the internal wiring and circuits in CKP sensors. Bent, broken or worn reluctor ring teeth can also generate a weak or unstable signal, which the ECM will be unable to analyze.
What happens when Reluctor wheel goes bad?
One of the first symptoms of an issue with the ignition trigger is problems starting the engine. If there is any issue with the ignition trigger or reluctor wheel it may compromise the signal to the computer. The engine may take more cranks to start than normal, or may require several turns of the key before firing up.
What is a toothed reluctor wheel on a Chevy LS?

Do all LS cranks come with a reluctor wheel?
Most aftermarket crankshaft manufacturers sell LS cranks with the wheel already installed, but it’s possible that you bought a crank where the reluctor wheel is sold separately. This isn’t a simple matter of hammering the wheel onto the rear of the crank.
What are the different types of wheels for an LS engine?
There are two styles of wheels: Gen IV LS engines (2005-Present) – includes LS2, LS3, LS7, L76, L99, LY6 & more … In most cases, you can identify a Gen III or Gen IV by the location of the camshaft sensor.
Where is the crankshaft position sensor on a GM LS engine?
A magnet sensor mounted stationary in the block is aligned to the wheel and picks up crankshaft position. GM LS engines feature a toothed reluctor wheel (also called a tone wheel or tone ring), which is press-fit onto the rear of the crankshaft. This toothed wheel is used by the crankshaft position sensor for ignition timing.
