Do balance shafts need to be timed to the crankshaft?
One counter-balance shaft is rotated clockwise and the other counter-clockwise. The shafts are timed to the crankshaft so that when the piston is at TDC both masses exert a downward force. To counteract the secondary force on the engine, the balancer exerts an opposing force only when it is necessary.
What does a balance shaft delete do?
This configuration allows the front balance shaft to rotate in an opposite direction to the rear balance shaft, thereby cancelling unwanted horizontal forces.
Why do people delete balance shafts?
Reasons to remove your balance shaft Because the balance shafts rotate at twice the engine RPM, their bearings can take quite a beating. Any secondary vibration in the rotating assembly first gets absorbed by the main bearings, transferred to and then cancelled in the block by the balance shafts.
How to design balance shaft timing gear alignment?
1. Install the balance shaft drive sprocket. 2. For the 1st design balance chain, install the balance shaft drive chain with the colored links lined up with the marks on the balance shaft drive sprockets and the crankshaft sprocket. There are three colored links on the chain. Two links are of matching colors, and one link is of a unique color.
What happens if the balance shaft is not timed?
Important: If the balance shafts are not properly timed to the engine, the engine may vibrate or make noise. There are two possible chain configurations for these engines. Both configurations use a unique chain link to line up with the intake side balance shaft sprocket timing mark. The first design uses a unique link color (1).
Why are balance shafts used for single disk clutch?
Balance shafts reduce harmonics and allow your single disk clutch to shift very nicely. We know it’s hard to believe. It may not make sense that the balance shafts driven by belts, and that are not directly connected to the crank, will be able to do this, but amazingly it somehow works!
What is the purpose of balance shaft gear?
The Balance Shaft Gear. Your balance shaft gear is part of your engine, the component that balances out all the other components within your engine. Its main purpose is to eliminate vibrations, especially when you achieve higher speeds.
