Where is the timing mark on a balance shaft?
The mark for the front shaft is a little notch on the case and there is an arrow on the pulley. Line the arrow up with the mark on the case when the crank is lined up with the timing mark.
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).
How to reset the balance shaft chain tensioner?
• Install the upper and small balance shaft drive chain guides and bolts and tighten to 106 IN/LBS (12 Nm). • Install the adjustable balance shaft chain guide and bolt and tighten to 89 IN/LBS (10 Nm). • Reset the timing chain tensioner by performing the following steps:
How do you balance a belt drive pulley?
Rotate the pulley by hand and let it come to rest on its own. Mark the point at the very bottom center of the pulley. Rotate it again and let it come to rest. If it stops with the same point at the bottom center, then its weight is not balanced – the pulley is heavier at that point.
The mark for the front shaft is a little notch on the case and there is an arrow on the pulley. Line the arrow up with the mark on the case when the crank is lined up with the timing mark.
Can a pulley be unbalanced but statically balanced?
It is possible for a pulley to be statically balanced but dynamically unbalanced (although the reverse is not true), so dynamic balance must be measured while the pulley is turning. For a dynamically balanced pulley, the center of mass coincides with the center of rotation.
Can a water pump be used as a pulley?
Engine Application: All racing. Accepts standard pulleys NOTE: Can be used with a water pump pulley and belt P/N 9433722 without an idler pulley or alternator. NOTE: Can be used with a water pump pulley and belt P/N 9433722 without an idler pulley or alternator.
How to reset timing chain tensioner on balance shaft?
• Reset the timing chain tensioner by performing the following steps: • Rotate the tensioner plunger 90 degrees in its bore and compress the plunger. •Rotate the tensioner back to the original 12 o’clock position and insert a paper clip through the hole in the plunger body and into the hole in the tensioner plunger.
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 is the balance shaft connected to the oil pump?
The left balance shaft that’s directly connected to the oil pump driven gear and the right balance shaft that’s driven by the balance shaft belt over the oil pump sprocket. Two balance shafts rotate in opposite directions at twice engine speed.
