How do I know if I have 24x or 58x?

Secondly, all 24x wheels are detected by a black sensor, while 58x use a grey sensor. This sensor is located at the back of the block, near the oil pan, on the passenger side of the engine, just above the starter.

What LS engines are 58x?

Installation and Removal Tips for LS Engine 24x or 58x Reluctor…

  • 24-tooth reluctor wheel (24x) Gen III LS engines (1996-2007) – includes LS1, LS6, LQ4, LM7 & more.
  • 58-tooth reluctor wheel (58x) Gen IV LS engines (2005-Present) – includes LS2, LS3, LS7, L76, L99, LY6 & more. …

How does the Reluctor work?

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.

What does a distributor Reluctor do?

ignition systems …a magnetic device, called a reluctor, that is operated by the distributor shaft to produce timed electric signals, which are amplified and used to control the current to the induction coil.

Is the reluctor wheel on the rear of the crank?

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.

Where is the crankshaft reluctor wheel on a corvette?

GM part number 12552953. Crankshaft reluctor wheel images: Left image- 24X crankshaft reluctor wheel found on all Gen III V8 engines (LS1, LS6, LQ4, LQ9) and early Gen IV V8 engines (2005 LS2 Corvette, 2005-2006 LS2 GTO, 2005-2006 LS2 SSR). GM part number 12551520 or 12559353.

Where is the reluctor wheel on a LS engine?

The reluctor wheel (again, also called a timing wheel or tone wheel) is interference-fit onto the rear of the crankshaft, with no key or other registering device.

Can you re-use an OE crankshaft in a new engine?

Whether you plan to re-use the OE crankshaft that was included in your new or used engine, or are planning to install an aftermarket performance crankshaft, you may run into a situation where the reluctor wheel needs servicing.

What kind of wheels do crankshaft reluctor wheels use?

24 x crankshaft reluctor wheels. No cam reluctor machined into camshaft. Cam sensor moved to front timing cover. Camgear used was “type C” 1 x signal below and held on by 3 bolts. 58 x crankshaft reluctor wheels.

Where is the crankshaft reluctor located on a GM Gen III engine?

The Gen III crankshaft reluctor wheel is mounted on the rear of the crankshaft and within the engine block. The outer diameter of the crankshaft reluctor is exposed through a hole in the side of the block above the starter. The CKP sensor seals the sensor hole and returns a 24-pulse signal to the PCM while the crankshaft is turning.

GM part number 12552953. Crankshaft reluctor wheel images: Left image- 24X crankshaft reluctor wheel found on all Gen III V8 engines (LS1, LS6, LQ4, LQ9) and early Gen IV V8 engines (2005 LS2 Corvette, 2005-2006 LS2 GTO, 2005-2006 LS2 SSR). GM part number 12551520 or 12559353.

How many teeth does The GMIS 58X crankshaft reluctor have?

This sensor is designed to ìreadî only one row of teeth from the crankshaft reluctor wheel. Where the 24x crankshaft reluctor is made up of two, out-of-phase rings, the 58x crankshaft reluctor contains only one row of 58 teeth. This gray CKP sensor is unable to properly produce a signal from GMís 24x crankshaft reluctor.

How do I know if I have 24x or 58x?

One easy way to tell which reluctor wheel you have is to look at the crankshaft sensor. If it’s black you have a 24x wheel; if the sensor is gray then you have a 58x wheel.

What is 24x crank?

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.

Are crank sensors interchangeable?

The Crank Sensor is the same exact part.so if you need both just buy 2 of the same part number. if you need just one,it don’t matter which one you ask for,even the parts people can’t screw this up because they are both the same sensor,crank or cam sensor.

What is a 58x engine?

58-tooth reluctor wheel (58x) Gen III engines featured the cam sensor mounted at the top rear of the block, while Gen IV engines feature the cam sensor mounted onto the timing cover. [Read: How to Identify an LS Engine.] This is important to note for those who plan to use an aftermarket timing control unit.

What is a 58 tooth reluctor wheel?

engine gm. Around 2005 or 2006, GM started using a 58-tooth reluctor wheel, where before they used a 24-tooth wheel in the LSx based engines (LS1, LS2, LS3, etc.). This wheel is used as a way for the computer to detect where the crankshaft is at in its rotational cycle.

Where is the camshaft sensor on a LS1?

The cam position sensor is located at the rear of the block, behind the intake manifold, and above the camshaft.

How do Reluctors work?

function in direct-ignition systems 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.

What is ignition trigger?

The ignition trigger is an electronic mechanism of the vehicle’s engine management system, commonly found, in one form or another, on a large number of road going cars and trucks. Most ignition triggers operate as a magnetic sensor that is “triggered” as the unit rotates.

Is there a difference between crankshaft sensor and camshaft sensor?

The crankshaft position sensor monitors as a multifunctional sensor used to set ignition timing, detect engine RPM and relative engine speed. The camshaft position sensor is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.

Are cam and crank sensors the same?

The camshaft position sensor monitors the rotation speed of the camshaft, which indicates valve position in the combustion cycle, while the crank position sensor monitors speed of crankshaft rotation, which gives piston location.

When did GM switch to 58X?

With the evolution of the Gen IV LS2 in 2005, one change relocated the cam sensor to the timing chain cover. The cam gear also doubled as the cam sensor trigger wheel remaining a 1x for 2005. That evolved in 2006 when GM switched to a 58x crank reluctor, which demanded a 4x trigger for more resolution.

Are all 5.3 cranks the same?

For the most part, the 3.622-inch crankshafts used in the 5.3L, 5.7L, 6.0L, and 6.2L Gen III/IV engines are all the same. Also, all LS-series crankshafts built prior to 2009 have a universal six-bolt flywheel/flexplate pattern.
