LS Cam Bearing Install Tips! Engine Building 101

Engine building is all about precision. Take camshaft bearings, for example. They may look alike to the naked eye, but they’re sized to fit into the cam housing bore in a specific order. They also have to be driven into position perfectly straight, with the oil galley holes lined up. If you’ve done everything right, once the camshaft is in place, it should spin by hand with ease!

In this Summit Racing Equipment Engine Building 101 video, your instructors Brian and Mike demonstrate the proper way to install cam bearings in a LS Gen 3, LS Gen 4, or LT Gen 5 engines. They’re using a late-Gen 3 LS engine block that they rescued from the returns bin and turned into a project 408, but the same techniques work on all of these blocks. Brian and Mike share several helpful tips, including cleaning, how to determine bearing order and orientation, and test fitting the camshaft.

They also show us how to operate the Summit Racing cam bearing installation tool. Sometimes called a cam bearing driver, cam bearing tool, or knocker, this tool has a bearing die and centering cone sized specifically to fit the cam journals of Gen 3 LS engines. The removable bearing die allows you to install the first three bearings, and then reverse the tool in the block to install the last two. The same tool can be used to drive out old bearings as well.

The right tool can make any job easier, so grab your Summit Racing camshaft bearing installation tool for late-model LS engines, available only at SummitRacing.com!
