I always respect anyone who confesses a mistake when they could have easily carried on with no one ever knowing. In this case it not only shows you're honest it also shows you really are interested in educating others as best you can which includes mistakes that are easy to make ad how to avoid them. I'm currently installing cam bearings in my LY6 so I appreciate the information. All the best.
Great video with good information, I’m rebuilding a lm7 5.3 now and installed cam bearings twice already with trouble.The first was with a universal cam bearing tool so I bought the Summit cam bearing installer and all went in great but had binding when installing original cam back in engine that showed no sign of wear or damage. Watching your video has convinced me to replace the cam with a new one! Thanks!
Thank you for this video, doing an early model LQ4 and this is exactly what I needed.
Matt you do a really good job with these videos. You use the right terminology, seem to know what you are talking about, and get great camera angles. Well done man!
Thanks so much for the compliments!
Love it! All the other you tubers just send it with old cam bearings! I’m so glad I finally found your videos definitely got a new Sub and all the likes 👍 I can give
Excellent video, couple things i do different, remove the rear bearing first if i'm taking it off the stand and set the engine up vertically ( less bounce), and after two bearings installed trial fit the cam after each subsequent bearings installed, and don't lube the od of the bearings, but that could be debated to infinity.
Excellent Video, Patience is the key!
Great tips at the end . Great video !
Awesome video! I want to rebuild my Silverado engine and this was extremely helpful
Thank you for telling us about the issue that you had with the old cam! I ordered the summit cam tool a few days ago. Now it's time to watch the main bearing video of yours.
No prob! Good luck!
Did you ever get the cam bearings tool from summit? I ordered one over a month ago and they still haven’t shipped it yet.
@@crawsmith4388 Not yet, They sent a email asking if I wanted my money back or if I still wanted the tool? I replied with It's not a problem waiting since I won't be using until the weather warms up some. Early to mid summer would be fine
@@crawsmith4388 Yes. Call them.
Awesome video! As a fellow Motorcycle mechanic, its great to see the same attention to detail applied to this. So many people out there just wing it and hope for the best. Subscribed!
Thanks!
Looks like the same Snap On hammer I have. Did the same thing ….handle rotted and came off. Snap On rep said they had issues when he made it up. Good video.
Nice job! and Nice tool.... kudos to Summit
Very much so.
Thank you!
That tool is probably the best cam bearing tool you can get for an LS. Its only real downfall is that it won’t work for any other engine. But if you do ANYTHING with LS engines, it is DEFINITELY worth getting.
That type cam bearing driver has been around for years, back in the 50s I worked in a local automotive machine shop and we had a cam bearing driver set made by Hub City that used slugs , the only problem is that you need a slug for each size cam bearing. I have installed thousands of sets of bearings with a tool like that, I have made my own set as I need them.
+1 for honesty.
Do they call for oil between the outside of the bearing and the block. Wouldn't they need to go in dry as to not spin a bearing?
I place the block standing vertically and utilize gravity on replacing cam bearings and camshaft install..
Thanks!
Awesome video thank you!
Great video but I am curious about your remarks at the end. What would have happened if you were reusing the original cam since it did not work with the new cam bearings? Did you ever find what caused the problem with the new cam bearings and the old cam?
Great video, but definitely should not be putting lube behind the bearing surface. You would want lube on the inside of the bearing so your tool doesn't mar the bearing surface. Although, you can put a very small amount of Green loctite behind the bearing to make sure it doesn't spin....which your oil will help it do.
Yeah I came here immediately after seeing that I hope it works out
The owner of a Rod Shop near me (he loaned me his cam bearing installation tool) who specializes in LS told me he always greases the outside of the bearings he installs and hasn't spun a bearing yet. Been in business for many years.
@@renaissanceman7145 Weird, its common knowledge that is exactly what you should not do.
@@alexanderknight7793 Is it?!
As you may, or may not, know Summit Racing produces a video series called "On All Cylinders". April of this year they released a video on this very topic. Here's a link
www.onallcylinders.com/2020/04/21/engine-building-101-cam-bearings-install-on-ls-engine-video/
In the video they lube the cam bearings and were questioned about it in the comments. In their reply they said Dura-Bond and Clevite says to use lube.
I can understand the thought process that concludes, lube between the block and bearing increases the possibility of spinning the bearing. I also understand the thought process that concludes, as hard as I had to pound on that tool to get that lubed bearing installed, it's NEVER going to spin. (Especially if the camshaft spins easily by hand when installed)
Edit:In the same reply they also said to "never use something like anti-seize."
I’ve heard MANY say to NEVER use something like Loctite since it inhibits heat transfer from the bearing to the block.
Always have the line bore checked before installing new bearings to start with especially if it's still stock and your going aftermarket parts with no machine work on a stock block.
Aawesome vid
Wrap a rubber band behind the cone and it will keep cone pushed tight into bearing journal so u don't have to hold it , kinda a 3rd hand
What would you advise for a new cam on old bearings? Got a 5.3 LS with 125k miles and the cam bearings don't look amazing but theres no copper visible on them. I really don't wanna pull the whole motor for what started out as a simple DOD delete.
Did you have good oil pressure prior to disassembly?
Same here I had good pressure.
🤘🔥
I used mahle cleeeeeevite too
where did you get the adjustable table, do they shorter ones?

Who does hvac. Love those scrub wipes
Hvac?
@@HTMR Those are heating and refrigeration wipes. Read the tub
Does the tool have a stopping point for install? Or are you eye balling it?
I don't think any of the tools have a "stop". Get it centered in web as best as possible and then make sure oil holes line up.
My 3rd Bearing spun, I'm adding a cam, question is Does the block need to be machined and need an oversized cam bearing? I know it's all have to be measured, I'm looking for a rough guess with someone who's fixed spun bearings before.
How did it go for you ? I have the same problem
Updates?
Honestly I had a motorcycle accident, all I can remember is if your cam is not damaged and it can be reused, then new bearings will set just fine.
Brake clean?
So if one or more bearing broke off into pieces inside is that a bust ? Or would I be able to just replace 😅
I have buddies that build Lots of LS engines and do their own engine work in the offroad scene and when they are building they run the motor and sometimes end up changing the cam in the vehicle and try different cam they run it maybe a month later change and reconfigure the engine. Its actually pretty easy on ultra 4 stuff no radiator in the front and so on. Did you ever figure out what happened other then the cam being used. So did you attempt to test fit the old cam in the new bearing first? I wonder if one of the bearings was not perfect from the factory.
Not sure, maybe I installed one of the bearings crooked or nicked it. Regardless, cam should spin smoothly once done.
@@HTMR Was that your personal build and how did it turn out.
@@crashedking1931 personal build hitting 10# boost every time I take it out. Been running great for 2yrs now.
@@HTMR Ok that's awesome thanks.
Would it have been better to just have put the cam bearings in a cold freezer so the cold could contract it then used a heat gun to expand it once it was on? Just think hammering it in is iffy just a tad bit
You sound like that fordtechmakuloco guy
Where did you get that table?!!?
czcams.com/video/maCQ4o3OsJ0/video.htmlsi=mzsUk0UeSlEwJ-nX
What if the crank and pistons were still in
What table is that?
czcams.com/video/-v1y437d4fQ/video.html
I have a 5.3 and 6.0, you wanna rebuild the motors? They’re about due.
Get a BHJ cam bearing tool , leave this antique stuff for beginners.
I thought you are not supposed to lube the bearing ??
For test fit or final assembly?
@@HTMR You do not use lube on either...if anything at all you might use green loctite, but you absolutely do not put lube behind the bearing surface.
Final assembly on o.d. of the bearing should be done dry, you would lube a cam in the bearing but not the bearing into the block.
You’re right you do not lube the outside of the bearing that goes into the block.
But you do lube what the cam contacts into the cam bearings. But the bearings installed into the block absolutely do not lube, that portion goes in dry and very clean. Other wise the rest of the video was spot on.
@@HTMR if you lube the bearing that goes to the block that’s a great way to spin a bearing. Do not listen to that part !
Great video but guys and future installers !!! Absolutely do not put oil on the outside of the bearing. Those surfaces need to be very clean and dry before install. Absolutely do not listen to that part of the video. Thanx !
Explain your reasoning?
@@HTMR that’s a great way to spin a bearing. That’s dumb for you
to encourage the in-correct way for install. Those go in dry and then lube the surface that actually has a rotating assembly. That part you’re explaining goes in dry. You and i both know that. Even in a build spec they specify do not do that. Ive built a lot of engines and that’s a great way to spin a bearing.
I'm trying to get a straight answer myself. Oil on aluminum blocks seems standard. I think on the iron blocks #2 and #3 bearings had spin issues so GM dealers and machine shops would use green or blue Loctite?
20:08 kid in background WTF 😂
Lol I have 4 kids right outside the garage
I almost pissed my pants laughing. That was awesome
Cleee vite lol
Good video tho👍🏽
you lost me when you put an old wore out cam in new bearings. thats all i need to know.
