What is a cam tool?
CAM-TOOL is a five-axis-control-machining-center compatible, high-end CAD/CAM system with a hybrid CAM engine (Polygon and Surface Calculation). In addition, CAM TOOL provides a superior surface finish, longer tool life, reduced machining time and finishing time.
When do you need a camshaft holding and lock tool?
Once you buy a new timing belt, you also need to purchase gasket adhesives and gaskets for your vehicle’s engine model. The camshaft holding and lock tools help you get the right timing on the timing belt once it is replaced. The timing of the engine valves is critical to the functioning of your engine.
Can you remove the timing cover on a camshaft?
Access the camshaft. Removing the timing cover is one of the most difficult parts of an in-car installation, if you’re going to attempt it without pulling the engine. The oil pan must be lowered enough to remove the timing cover while also clearing the crankshaft snout.
How are timing chains used in a DOHC engine?
In some engines, such as a Chevy 3.4L DOHC V6, a timing chain is used to drive an intermediate sprocket that drives two belts (one for each cam). Timing belts and chains carry a heavy load. They have to turn the cam with enough force to overcome the resistance of all the valve springs.
What do you remove from an engine to install a camshaft?
With the cover off the engine, remove the three upper timing-chain bolts, along with the lower timing gear if a new timing chain is to be installed.
What should the cam timing be on a DOHC engine?
If the cam timing was set to this smaller/narrower 110.5 degree lobe separation angle, the engine would behave much differently than the 113.5 degree lobe separation angle.
What happens if your camshaft timing is not correct?
If you answered “yes” to any of those questions, your camshaft timing may not be what the camshaft manufacturer specified. Improper cam timing can lead to reduced performance, increased fuel consumption and an increased likelihood of detonation.
How to change the timing on a Zetec?
You’ll want to remove the cam locking tool to prevent breaking the back of the cams out. Use a large wrench to hold the intake cam in place while you use a Torx bit (T55 I think) to loosen the intake cam bolt. You only need to loosen it enough so that you can move the cam gear free of the cam.
Do you have to degree the camshaft on a SOHC engine?
IT’S USUALLY NOT IMPERATIVE TO DEGREE THE CAMSHAFT (S) ON SOHC ENGINES. Unfortunately, the engine may also lose performance at higher engine speeds. Conversely, when all valve events are retarded with respect to crankshaft rotation, the engine will typically lose horsepower at lower engine speeds.
