How to remove and install cam bearings at home?
In order to remove and install cam bearings, you must have an install tool. You will be much better off purchasing a quality universal tool as opposed to a cheap bargain tool store unit. We got ours from Comp Cams. Note the box of bearings; we have them numbered 1-5 in order of placement in the block. 02.
What kind of bearings do I need for a camshaft?
When installing cam bearings, always work your way from the rear of the block forward. When fitting aluminum cam bearings, it’s important to allow sufficient bearing-to-camshaft clearance, since the harder aluminum alloy bearings won’t wear in as rapidly as babbitt bearings to make their own clearance.
What to do if Cam fit is too tight?
If cam fit is too tight, bearing material can be removed by reaming. Honing bearings to size is not recommended because honing stone grit can easily be trapped in the bearing surface, and its presence can lead to premature camshaft journal wear.
When do you start the cam bearing selection process?
The installation process begins after you’ve accomplished any machining that might be needed (cylinder boring and/or honing, align-honing, deck resurfacing, cam bore alignment, etc.). Before starting, make certain that the block is totally clean.
Where are the camshafts located on a Chrysler 300?
However, the number and positioning of camshafts vary depending on the architecture of the engine. For example, the gasoline Pentastar 3.6L V6 available for the modern Chrysler 300 relies on the DOHC configuration having two cams located in the cylinder head.

How do you remove a camshaft from an engine?
Mark the rocker arms before the camshaft is removed. Remove the bearing cap bolts, the bearing caps and the camshafts. Remove the rocker arms. Lubricate the cam followers with clean engine oil before installation. Position each cam follower onto the valve lifter and valve stem.
What are the bearing caps on a camshaft made of?
The valvetrain uses cam followers with hydraulic valve lifters. The camshaft bearing caps are made of powdered metal. The location and direction of each cap is marked on the side of the cap. Each camshaft is made from nodular cast iron and each has a pressed on magnetic timing wheel that is magnetically coded.

How are cam bearings aligned with oil gallery holes?
Some cam bearings have to be aligned with oil gallery holes, which is critical for the supply of oil to the crankshaft. I find marking cam bearings (with a permanent marker) where the oil hole should be, makes it easier to align. Aligning a hole PERFECTLY is possible…but hard to achieve.
When is the best time to replace cam bearings?
Once tightened, a hammer is used to knock the bearing out of the block. You want to remove all of the bearings before moving on, unless you are only replacing one. If you are at this point, there is no real reason not to replace them all. Now is the best time to thoroughly clean the block. 09.
