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!

I'm guessing this is the reason why my 2015 Chevy SS Sedan is having the dreaded "low oil pressure" indicator. I've replaced the oil pump, oil pressure sensor, and it's still reading that indicator off to me in my car. This was very a helpful, knowledgeable video.

Im getting ready to order this tool, a machine shop used the universal tool to install my besrings and atleast one is crooked. Is it safe to install a new set of bearings in my aluminum ls block, and not fear spinning a bearing. My journals were within spec originally.

@victor.hugo.differentialz 3 года назад

Does it have to be hit from the back? Can I get away from the front and leaving the block on the engine stand

@maxwolthuis 2 года назад

So if I understand correctly, the bearing positions go from front to back, 1 being the bearing next to the water pump and 5 being the one closest to the bell housing?

@Desert_guy Год назад

yeah watch the first three were done from the rear to keep the bar as centered as possible. Thats what they're explaining at 6:00. they flip the block and install the back two bearings from the front to keep the tool centered

some of the expandable ones do not have sufficient step on them for the tapered LS bearings and will damage the edges of the bearing babbit. gotta be careful

@guitargod66 3 года назад

So can the cam bearings be pushed in or out either way? Like there is no taper or anything in the cam bore is there? Also if you overshoot installing it from one side, can you just tap it back the other way with the installer?

@SummitRacing 3 года назад

Thank you for your question. The O.D. of the bearings change, but the I.D.’s will be the same. They can go in from either direction, but you will find going in from the opposite side gives you the best alignment. If you do go too far, yes it’s acceptable to just tap it backwards from that side.

@SS10guy012 Год назад

So I'm sitting here looking at my 6.2L L92 block that I just removed the stock cam bearings. In the bores where the cam bearings go, there is only a chamfer on one side of the bore (which is the side the bearings were just knocked out from). The other side of the bore has nothing to help guide the bearing in straight so your process in this video to install the bearings would not work. Now I am questioning "are all LS motors the same way with the single chamfer on one side of the bore?" If that's the case, then you're telling people to install the bearings from the wrong side in your install process.

@limabravo6065 3 года назад

I was told that with the ls y block design you should install the main caps before throwing the bearings in?

@SummitRacing 3 года назад

During any engine build, the main bearing clearances should be checked using a dial bore gauge with the main bearing caps torqued to spec. Watch this video for more information. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WYx-de7cyxs.html

@frazeysburgelites3490 4 года назад

Does it matter which direction you put the bearings in from? I'm ordering my bearings and tool right now and trying to prepare for install.

@SummitRacing 4 года назад

Thank you for your question. In general, the tool needs to needs to be the farthest away from the bearing being installed for best alignment. Meaning, the rear cam bearings would be installed with the cam in the front and the front cam bearings being installed with the tool at the back.

@mikeandmona 4 года назад

Same here, now I’m terrified to put these bearings in, thanks Summit 👍

@reggierendert6494 3 года назад

You're absolutely correct...they should go in dry just like crank and rod bearings. Greasing them is just asking for a spun bearing. There's no need for it anyway. Put them in dry.

@ls4.8frank 3 года назад

I've noticed Summit that you have not replied to any of the questions or comments about the cam bearings going in dry, why not? Cam bearings are suppose to go in dry because if not then that allows for the bearing to possibly spin much easier and the bearing to either stay stuck to the cam journal or spin out of the cam bearing journal in the block and walk out of the journal and cause a lot if damage or commonly referred to as a "spun bearing". Can you clarify why you used assembly lube and wether or not if it is correct to use lube or tap them in dry?

@SummitRacing 3 года назад

Thank you for your question. We did some research on this prior. Different bearing companies have opposing views. The light oil on the back of the bearing will not impact its ability to remain in place. The majority of it squeezes out as the bearing goes into the bore. The damage of a galled bearing backing from installing dry along with scraping material off the back is the reason we choose oil.

@reggierendert6494 3 года назад

Going by the opinions of guys with a lifetime of experience...I put them in dry.

@jameswiz 2 года назад

@@reggierendert6494 I solved this problem based on tips from really "Old Timers" and their tips and tricks. Works as a Lube and hardens to "glue" the bearing in. They and I use "Permatex Indian Head Gasket Shellac Compound".. It's messy, but cleans up great with carb cleaned when done. Just be sure to verify none is in the oil journal hole, and it works like a dream. Most of these guys are dead now, but they were the ones pioneering racing back in the 40s, 50s, and 60s.. Never once did any of the "tips" advice they gave me cause harm and they always worked. If you've never tried it. Next "junk" block you have, pop out the old bearings, and reinstall them using the compound on 1 or 2. You'll feel them slide right in. Give it a few days then bang them back out. It's HARD to get them out when that stuff cures. I've NEVER seen one spun after doing that

@matthewstorm5188 Год назад

@@reggierendert6494 I take it you haven’t worked with aluminum blocks. For iron, dry is fine. But you risk damaging the bearing bores in an aluminum block if you install the bearings dry.

@philipmazzuca2269 10 месяцев назад

WD-40 is all you need

@Hitman-ds1ei 3 года назад

That's great for an iron block but cold shrinking bearings for slide in fit is preferred for alloy blocks, banging metal backed bearings into any alloy block not good as any galling even the slightest can cause issues and losing crush in alloy block not desirable as they expand so much more than iron blocks at operating temps, so dry ice or if can get some liquid nitrogen and shrink bearings for any easy fit and when bearing expands it grabs alloy block better, if using liquid nitrogen be gentle and don't drop as babbit can flake off, i have never seen an LS cam bearing move using this method but you do what you think works for you

@spaight711 3 года назад

I'd go so far as to install them cold and using a shop press with the block standing on end. I get that not everybody has a press with that kind of clearance. But if you're skilled enough to rebuild an entire engine, you aught to be able to cobble something together with a bottle jack.

@matthewstorm5188 Год назад

This, of course, would be ideal. But for those of us who don’t have this option, using a lube is MUCH better than installing them dry.

@DeVoN420zz 8 месяцев назад

5:05 I'm pretty sure you should heat up the block and cool the bearing so you don't accidently mushroom the bearing & block and mainly to utilize thermal expansion, and contraction, it will go in without Binding

@SummitRacing 3 года назад

Thank you for your question. We think you may mean the SH-2125’s which are used for the cam housing bores from 2004 forward. Your SH-1814’s are for the 1997-03 models. It’s not easy to tell how old a salvage block is, but luckily even a dial caliper does the job. The individual cam bearings used in these sets differ by which bore they are in and have different part numbers even within the same set. Mike gets into this around the 2:15 mark.

@SummitRacing 3 года назад

Thank you for your question. The basic method to installing cam bearings will be the same for any gen. 3, 4 or 5 engine but the LM7 was used from 1999-2007. This means you will need to verify if you have the late 2003 and later block with the different cam housing bore. Here are the specs for each and you will need to order the appropriate cam bearing set we mentioned.

@dreamsteelgarage8418 2 года назад

While this is a good video, I think a major portion of the install was missed and that is the proper way to align the oil hole to the oil channel in the cam bore. Maybe it was just tough to show with a camera.

I've watched a lot of these install videos, they've all skipped that part for some reason.

@angelavalos8125 3 месяца назад

Do not grease the outside of the cam bearing. You run the risk of spinning the cam bearing. It goes in relatively easy without grease

@mikeschneider634 2 года назад

You should NOT lube the bearing before install. And you also need to check end play

@matthewstorm5188 Год назад

Maybe on an iron block. But if you install cam bearings dry into an aluminum block, you will gall the aluminum on block, which will cause the bearing to either go in crooked or become deformed by the metal buildup between the bearing and block. You could also seriously gouge the block, which would require line boring and oversized bearings. Dry installation is for IRON BLOCKS, not aluminum.

Why's that tool so long? It seems to me that it's almost twice as long as it needs to be, and aught to work fine if it were shorter. From a manufacturing perspective, nobody's going to make something with more material than needed unless there's a reason. So it must be intentional, but I'm just not seeing it... Is the same tool made for longer blocks, or something?

You NEVER want to install bearings dry into an aluminum block! Doing so can gall the aluminum, cause the bearing to install crooked, and (worst of all) damage the bore in your block! Remember, aluminum is very soft, and you are installing a bearing with an interference fit. While no lubrication is fine with iron, it can EASILY damage aluminum.

@matthewstorm5188 Год назад

@@nsmturbo5902 Here’s something else to consider. Even if you install the bearings dry, it is inevitable that oil is going to make its way into the nooks and crannies between the bearing and the block. Oil can easily seep into small spaces. And in the case of cam bearings, they even have a supply of pressurized oil.

@TheGamersRace Год назад

Please do not grease/oil the outside of any of your bearings. It can mess up your tolerances, and worst case you could spin a bearing. Not as dangerous on a cam bearing, but still not worth the risk.

@Desert_guy Год назад

Why not? The manufacturer says to lube prior to installation. Why would you go against what they designed specifically?

@TheGamersRace Год назад

@@Desert_guy The manufacturers specify that you should not place oil or grease between the block and the bearing. Doing so can decrease your tolerances, and in worst case scenarios you can spin your bearings. Most if not all bushing style bearings must be placed in a clean, dry block. Grease and oil are for lubrication, you don't need to lubricate something that will not see friction. Greasing the inner side of the bearing is almost always recommended.

The reason we replaced cam bearings was because the block had some machine work done to it and we wanted to be sure it was absolutely clean. That’s the only way to insure there is no debris in those galleys and grooves that could come loose and cause a problem once the engine is up and running.
