How many teeth are on a Chevy 350 flywheel?
A Chevy 350 engine flywheel typically has 153 teeth. The flywheel is a critical component in the engine's rotating assembly, providing a smooth and consistent power delivery to the transmission.
What is a Flywheel?
A flywheel is a heavy, circular disc that is attached to the crankshaft of an internal combustion engine. Its primary function is to store rotational energy and help maintain a consistent engine speed, reducing fluctuations and vibrations. The flywheel's teeth, also known as the ring gear, engage with the starter motor to crank the engine during startup.
Chevy 350 Engine Flywheel Specifications
The Chevy 350 engine, also known as the Small Block V8, is a popular and widely used engine in various GM vehicles. The flywheel for this engine typically has the following specifications:
- Number of teeth: 153
- Diameter: 14 inches (355.6 mm)
- Material: Cast iron or steel
- Weight: Approximately 30-35 lbs (13.6-15.9 kg)
The 153 teeth on the Chevy 350 flywheel provide a secure and reliable connection between the engine and the transmission, ensuring smooth power delivery and efficient operation.
Importance of the Flywheel
The flywheel plays a crucial role in the overall performance and efficiency of an engine. It helps to:
- Maintain a consistent engine speed, reducing fluctuations and vibrations
- Store rotational energy, which is then used to help start the engine and keep it running smoothly
- Provide a secure connection between the engine and the transmission, allowing for efficient power transfer
- Absorb torsional vibrations, which can otherwise cause damage to the engine and drivetrain components
Proper maintenance and inspection of the flywheel are essential to ensure the long-term reliability and performance of the Chevy 350 engine.
How many teeth are on a big-block Chevy flywheel?
All other big-block displacements used a 2-pc rear main seal, internal or “0” balance, and 168 tooth ring gear. They will accept the same flywheel as the early small-block engine. All Big Blocks can use the 153 tooth flywheel when the engine block is drilled for starter type.
How big is a 168 tooth flywheel?
You can measure the flywheel diameter. The 153 tooth is ~12 1/2 " while the 168 is ~14". You can pick apart stock style starters, as mentioned by others, by the position of the mounting bolt holes (staggered for big flywheel).
How many teeth does a Chevy 350 flywheel have?
There's 168 tooth flywheels and 153 tooth flywheels. The straight pattern is for 168, the offset is for 153.
How many drive teeth does a TH350 have?
Looks like the TH350 could be 7, 8, 9 or 10 tooth drive gear. However, 8 appears to be pretty common. What is your tire height or size? Based on your pulling of a natural 18-tooth from the trans with a 3.07 gear, This shows you may have a 1.84" 8-tooth drive gear.
How many teeth does a GM flywheel have?
Gen I and Gen II Chevy engines featured two available diameters of flywheels and two corresponding tooth counts of 153 and 168. Gen III, IV, V LS/LT series engines feature only the large diameter, 168 tooth flywheels, and flexplates, but carry either a 6, 8, or 9 bolt crank flanges.
What is the difference between a 153 and 168 tooth flywheel?
Other than the bolt pattern (and low torque verses high torque starters) the starters are the same. The starter will spin the engine faster with the 153 tooth flywheel, but the starter has more "leverage" turning a 168 tooth flywheel, therefore turns the engine over with less amperage draw.
What is the difference between SBC flywheel and flexplate?
Flywheels are typically found on vehicles equipped with manual transmissions, while flexplates are used in vehicles with automatic transmissions. A manual transmission has a flywheel that is attached to the crankshaft and has a clutch disk in between the pressure plate and flywheel.
How do I know how many teeth are on my flywheel?
Calculating number of teeth of an engine flywheel
- Start the engine and measure the frequency (Hz) at the generator's output (L-L or L-N)
- Run the excel file and add the frequency you recorded in A4 cell.
- Measure the frequency from the MPU and add it on cell G3.
- The result whill appear on cell I3 - and you are done.
How many teeth are on a C4 flexplate?
157 teeth
They are 157 teeth, neutral balance, 3.0" pcd for the six bolts, and have the same 9.5" converter bolt pattern as the Aussie C4 items. Any time a C4 was fitted to an Aussie Falcon 6, it lost 3 teeth form its 160 teeth flexplate, and got a 157 teeth item.
How do you know if your flywheel teeth are bad?
If your flywheel is damaged or has surface contamination, then your clutch might not be able to get a firm grip on the wheel. Sometimes, clutches go to the other extreme and stick to warped or damaged flywheels. Or, they suffer from chatter problems where they skip on and off their wheels rather than attach to them.
