Can you change Reluctor wheel on LS crank?
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 does the Reluctor wheel do?
Also referred to as a tone ring or timing wheel, the reluctor rides on the back of the crank and is read by a magnetic sensor located on the outside of the block near the starter. The magnet reads the teeth on the wheel and this gives the ECU accurate crankshaft position.
How do you remove a Reluctor wheel?
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.
What is the Reluctor wheel on a LS engine?
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.
Where is the Reluctor located?
The reluctor ring is mounted on the crankshaft so that as the crankshaft rotates the magnetic sensor is triggered by notches in the reluctor ring. The magnetic sensor provides position information to the electronic control module, which governs ignition timing.
How do I relearn my crankshaft position sensor?
- Turn off all of the accessories.
- Accelerate the vehicle to 55 mph at part throttle.
- Cruise at 55 mph for another 5-6 minutes.
- Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
- Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary.

What is a reluctor wheel on an engine?
Any builder familiar with late model engines knows that an engine’s computer control system monitors both camshaft and crankshaft position in order to achieve correct spark and fuel delivery. Many crankshafts feature a press-fit toothed timing wheel, referred to as a reluctor wheel.
