Why do engines need balance shafts?
Why do engines need balance shafts?
[149 Pages Report] A balance shaft is designed to rotate and vibrate in a way that reduces the vibration produced by an engine. Balance shafts are commonly used for engine refinement. Four cylinder engines use a tow shaft, which turns in opposite directions on either side of engine’s crankshaft.
Do all 4 cylinder engines have balance shafts?
Overview. Balance shafts are most common in inline four cylinder engines which, due to the asymmetry of their design, have an inherent second order vibration (vibrating at twice the engine RPM) which cannot be eliminated no matter how well the internal components are balanced.
Why would you delete a balance shaft?
Reasons to remove your balance shaft Because the balance shafts rotate at twice the engine RPM, their bearings can take quite a beating. So in terms of minimizing bearing load, the balance shafts don’t have any benefit. As such, it seems almost necessary to remove the balance shafts for a performance build.
What happens when timing marks are 180 degrees off?
So if you have both timing marks correctly lined up, the timing belt installed and rotate the crankshaft one revolution the timing mark on the crankshaft will be lined up once again but the camshaft will appear to be 180 degrees out. A second revolution of the crankshaft will bring both timing marks…
How do you remove a balance shaft from a car?
1. Remove timing belt, downpipe, transfer case and oil pan. 2. Remove alternator, power steering pump, cross member, front and left motor mount to drop the engine low enough. 3. Remove the front case with the left balance shaft attached. This involves pulling the crank shaft sprocket and everything else over the front case. 4.
How does a balance shaft bearing get installed?
Cover the crank shaft key with a cloth to prevent damage to the oil seal when pulling out the front case. Oil is fed to the right balance shaft from the main oil galley. The bearing is installed with the clinch positioned at 12:00 and the oil hole to the right so that it aligns with the main oil galley opening. 4. Balance shaft bearing install
Which is the front end of a balance shaft?
You can use the balance shaft’s front end since it has a larger diameter than the rear bearing. The left balance shaft bearing can be eliminated since the oil is fed through the shaft and not from the block. 5. Stub shaft install Use red Loctite or equivalent! Install the oil pump gears so that the timing mark are shown.

How do you get your timing 180 out?
Pull the distributer body from the engine before rotating your engine’s alignment to TDC. Then, carefully reinsert the distributor so that its spark transfer blade is pointed directly at the #1 port when bolted down.
