Which bearing are used for crankshaft of IC engines?
The sliding bearings used in internal combustion engines: Main crankshaft bearings support crankshaft providing its rotation under inertia forces generated by the parts of the shaft and oscillating forces transmitted by the connecting rods. Main bearings are mounted in the crankcase.
What is the main function of the crankshaft?
The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion.
What is the difference between camshaft and crankshaft?
A camshaft uses egg-shaped “cams” to open and close engine valves (one cam per valve), while a crankshaft converts “cranks” (the up/down motion of the pistons) to rotational motion.
Does the camshaft turn faster than the crankshaft?
Because one turn of the camshaft completes the valve operation for an entire cycle of the engine and the four-stroke-cycle engine makes two crankshaft revolutions to complete one cycle, the camshaft turns half as fast as the crankshaft.
Which type of crankshaft is preferred in high speed engine?
In the high performance crankshaft world, the nickel-chrome-moly alloy SAE-4340 (AMS-6414) has been a favorite in both forged and billet applications. It is used because of its very high strength and fatigue properties, coupled with good ductility and impact resistance at high strengths.
Which tool is used to remove the crankshaft pulley?
A half-inch drive impact gun might be a great tool for removing a stubborn crankshaft pulley bolt. A torque wrench has also been proven to be a helpful tool for correctly securing it. You might want to follow the service manual when removing the crankshaft pulley.
How do you remove a pulley without a puller?
There is a way to do it. You put a wrench on the pulley bolt and block the other end against the floor or the frame. Then you use the starter motor to turn the engine (DO NOT START IT, JUST TURN IT) for at most one or two revolutions of the crank. Just enough to break the bolt loose.
How do I keep my crankshaft pulley from turning?
Jam a pry bar/screwdriver btw the torque converter (5AT)/flywheel (6MT) teeth and the case. This will enable you to stop the crankshaft pulley from turning in either direction. Grab a torque wrench and tighten the bolt to 180ftlbs or 45ftlbs+ additional 60 degrees. Caution: Please go easy and be safe!
Is crankshaft pulley same as harmonic balancer?
A harmonic balancer is a front end accessory drive component that is connected to the crankshaft of an engine. Harmonic balancers do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others.
What happens if you drive with a bad harmonic balancer?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
