No, just drive them out with a cam bearing tool and throw them away. DO NOT REUSE THEM. Now they do go in a certain way, just make sure that the oil hole is not covered up by the bearing.
That requires a SPECIAL TOOL to remove and install the cam bearings correctly. It will be hard to find someone that has that tool, and let you use it. You need to just take the engine to a machine shop and let them do it for you. It may cost about 25.00$ plus the bearings.
Your cam bearings should be numbered in a particular order
Yes the cam bearings are the same.
Cam bearings are pressed into the block therefore there is NOT an adjustment.
roller bearings are only needed if engine has roller bearings, u would replace bearings with same bearings that are in engine and cam specs
YES, NEW cam bearings increase oil pressure and Improve oil lubrication through out the valvetrain. The cam bearings MUST be in GOOD shape if you want the engine to last.
Cam bearings, Main bearings, Rod bearings.
2.7L doesn't have cam bearings. It has Cam towers. There is no Bearing in there. Look for torque of Camshaft Towers.
Wheel bearings, main bearings, connecting rod bearings, cam bearings, axle bearings, carrier bearings, pinion bearings and so on, need to be more specific.
The cam is held by the 3 bolts that holds the cam gear on the block in order to remove the cam shaft you have to remove the distribitor & intake & loosen up your rocker arms & remove the push rods &lifters.
The first step is to buy or rent a cam bearing installation tool. Check your local auto parts store. It should come with instructions, but you will probably need to take the engine completely apart in order to be able to get the old bearings out after you drive them through to an open space. There's not enough room to reach up in there and get them out with the crankshaft and rods in the way.
If all the lifters are out of the way, the cam should slide right out. Worst case scenario would be to remove the rear soft plug and drive the cam forward. This would likely ruin the cam bearings, which can be replaced.
