What is a cam drive?
What is a cam drive?
A camshaft is a rotating object— usually made of metal— that contains pointed cams, which converts rotational motion to reciprocal motion. Camshafts are used in internal combustion engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers.
How does the phaser timing gear drive work?
The Phaser kit includes a new reluctor wheel and the other gear-drive items shown here that take the place of the factory chain-driven timing set components. The pictured CNC machined reluctor wheel works with the crankshaft position sensor in the EFI engines to provide the vehicle computer (PCM) accurate crankshaft position information.
Do you need a timing chain for a Milodon Cam?
Cam timing accuracy and consistency are the key to accessing 100% of the cam’s available power. A timing chain or an “easy to install” $150 gear drive can not provide this. Milodon’s professionally proven “Fixed Idler Gear” system is capable of maintaining the precise cam timing required to allow the cam to work to its maximum potential power.
When did the Phazer 6.5L timing gear drive first appear?
This product review first appeared here in The Diesel Page in 1998. Many product reviews have come and gone since that time, and we sometimes forget just how important these can be to owners of the 6.2L and 6.5L diesels.
What are the timing gears on a Chevy LT1?
Chevy has also used two different timing gears on its LT1 V8 engines. The earlier 1992-’95 LT1 engines with aluminum heads use a p/n 10128349 cam drive gear with a small hole with 16 splines in the center. On 1995 and later LT1s, a different gear (p/n 10206039) with a larger, unsplined center hole is used.
Where is the timing gear located on a Detroit Diesel engine?
The crankshaft timing gear, pressed onto the front end of the crankshaft, directly drives the bull gear and oil pump drive gear, and indirectly (through the bull gear), drives the air compressor and power steering pump drive gear, accessory pulley drive gear and water pump drive gear.
How does the timing of a cam drive work?
If an engine is being built for a particular application (stock, street/strip, drag race, circle track, you-name-it), how the cam is timed relative to the crankshaft will depend on the cam grind selected, the valvetrain, the gearing and final drive ratio, and what kind of power curve the customer wants. With stock engines, it’s a no brainer.
Where is the camshaft drive gear located in a diesel engine?
The camshaft drive gear is part of the camshaft gear assembly and is located in the cover of the assembly.
What is the timing of the fuel pump?
Time Engine pump timing begins with the timing of the fuel injection pump drive gear to the camshaft gear. The first step is the location of TDC of the compression stroke for cylinder Number 1.
