How To Install and Set Up Roller Lifters, Roller Rockers, and Pushrods

by birtanpublished on September 3, 2020

Greetings viewers i am eric the car guy and i want to thank you for tuning in today i'm also going to start by saying that this video is actually taking from a larger longer video about the assembly of the engine that went into this 1990 c 1500 that's behind me I took the 350 of

It was in it turned it into a 383 and this video covers the installation of the lifters the push rods the rocker arms and all those things that work in the valvetrain I got all my stuff from Comp Cams I'll

Link that down in the description for you the procedures as I showing here pretty much cover those those little details and things that you might want to know if you're assembling the valvetrain on your engine in particular

A small-block Chevy but I believe a lot of this information will carry over into other engines as well anyway I'm done talking let's get to the action already in progress we'll catch up at the end see you that as per instructions my

Lifters have been living in a bath of engine oil actually for two days now it wasn't an overnight deal but now it's going on a little bit longer than that they were cleaning everything before they went in the oil and now they were

Ready to be installed but I think you'll see why these have to go in before the cylinder head heads because I stick up too far make sure that the link is facing away from the cylinders you don't have to pump these up or

Anything just the soaking will do so what makes this a roller cam as these little wheels on the bottom here or what's coming in contact with a cam reduces friction and frees up horsepower off-camera I just tried it I tried to

Get these lifters out without removing his cylinder heads and I was able to do so in this this has a nine inch deck height I believe and my Ford has like an eight and a half so that half inch might be the difference so that's where that

Comes in as long as we're talking about valvetrain parts these are not the valve springs and retainers and keepers that came with these cylinder heads these have actually been switched over to comp cams stuff and as I believe I mentioned

Earlier the pocket has been machined a little bit wider so they can accommodate a the washer that goes underneath the spring here hopefully it was only wider and not deeper because AFR is very specific about this not going any deeper

Than it already is new push rods new locks for the rocker arms rocker arms are soaking in oil right now they were cleaned and all that stuff was done previously these are the retainers for the push rods these are the rocker arm

Studs and these are also AFR I'm gonna install the rocker studs with the push rod retainers loosely I'm not torquing them down yet because I have to align the push rods first I'm also going to use a little bit of this air pea

Assembly lube on the threads of these as well and these look like ya believe these are 3/8 and I'm pretty sure that the AFR heads came with like 3/8 rocker studs already our towel is a work something like this

And once you've got these that seems awfully tight once you've got these installed they say to weld it together you can like TIG weld these together why am i screwing this up set okay our means are Eric so our goes like this

Pay attention stop talking to the camera and actually do build the engine alright so as I was saying what they do is after you get these have movement so you can basically figure out the exact placement so once you've got everything in place

And everything is locked down what they talked about was like TIG welding in here which I'm not going to do I thought about this and I'm like alright well the only time that's gonna matter is when you go to remove and hopefully that's

Not on the car so if the heads off the car you can weld it then and TIG welding won't leave like slag or anything flying around like a MIG welder would but that's what they recommend so once you've got these in place or whatever

You weld it down then when you take it off you can also mark what cylinder this went to and you can just put this back on as an assembly instead of having to adjust this every time you do this but this is the first time so we got to do

It well there were just a little stiff gun in it first I'm just going to Snug these up for now not taken to the final torque I want them so I can like I said I can move these around like in and out

Why would you prefer screw in studs over press and studs normally what they do at the factory is they'll press these studs in rather than have them thread it in like this it's not a high horsepower application it doesn't have as much

Stress being put on these components because the push rod on a higher lift camshaft especially is pushing up really hard the strings the springs are also harder are also stronger and pushing back so there's a lot of forces being

Exerted onto this and if it's just pressed in and come right out so I'd say even if you're using stock heads and they don't have threaded rocker studs get yourself some threaded Roger stuff the best setup of all I believe though

Is like a shaft rockers setup and that means like most if not all of the rocker arms are on a shaft mounted system and that really locks them down it's expensive though super expensive also the size of that stud these are 3/8 I

Think the other studs are 7/16 breathing inside we're really actually because like I said when you first start running these down it doesn't feel right but it seems to get past the first couple of turns is okay and Leija these are

Expensive and I don't have time to fix them here are my push rods also from Comp Cams they don't have a top and bottom if they did they would be marked like upper top or something like that and you get a

Push rod and you get a push rod and you get a push rod and you get a push rod and you do get a push rod I think you get the gist make sure they're in the lifters basically that hole that runs down through the middle of that is where

The oil comes out of the lifter up through this push rod and lubricates the inside of the rocker arm which as it exits the rocker arm lubricates the valve and everything else so it's kind of a vital component in the oiling

System and you get a push rod and sure I am the pushrod fairy spreading pushrods throughout the land and no longer run twenty w50 in the Fairmont so this makes for a really good assembly Lube or soaking things like the rocker

Arms that I told you about they're full roller rockers so they have rollers here and roller at the tip and I talked to the people at Comp Cams aluminum rocker arms are sort of falling out of favor for these steel versions so

They they prefer these steel rocker arms over aluminum ones and they do like make this stuff for a living and I think they know a couple people when racing you know stuff like that I guess what I'm trying to say is I think their opinion

Has value and the argument is apparently the aluminum has more of a tendency to break even though it's lighter even though these steel ones are heavier they're stronger they hold up better and the rocker arms are just rocker arms

They aren't like intake and exhaust at least on this engine you see how these two rocker arms are sort of splayed out like this we want the angle of attack to be directly on the tip of that valve so that's what

These push rod guides are for so watch what happens when I slide the guide around in here see now those are more directly in line but then I want to come over and look at the push rod and make sure that that is also where I like it

To be and then once it is where I want it I'm going to tighten it down with my wrench sneak in underneath and then I'll just slide the rocker off torque it down to spec and move on and then we'll set

Everything else open the valve train that's going to hit the inside of the head sadly I don't really want that don't want a rubbing there I'll just go a little bit in on this one all the way over and then in just a bit if I can get

In here with the wrench or I'm just gonna have to pop that off of there I want the tip of that roller to hit that top of that valve square that's my whole goal with all these

The ones on the end seem to be the ones the hardest to get to behave and I think that's the way chevy design there so they got to exhaust ports right next to each other if they were spread out evenly maybe that would be different but

Just because of everything that's going on inside the cylinder head there seems to be less room for adjustment on the ones on the ends and there isn't the ones in the middle yeah I can't get this one over any farther the same with all

The money ends now my plan is to go through torque them all after they're torqued rechecked them and but then I'll put the locks on and then recheck them again we'll just keep checking and rechecking until we're done checking

Until we're sure well we're never sure until we start it up and it runs and it doesn't explode then everything's as right as it can be one more thing I should share with you about these rocker arms it was hard to show you when they

Were covered loyal were you notice inside the roller part there's a side that has a flat then the side that has the round so you want to be sure when you install these that the flat side is up and not the round side flat side so

These are the locks that go on top of those studs right now they're down towards the bottom I'm just going to run them up towards the top of the adjustment before I install them and make sure like I said all the flat sides

On those rockers are pointing out because that's what these rest against if I mention how much I like this socket on the crank it's really great now I need to go through and adjust all of these for proper well preload on the

Lifters and to do that you need to adjust them to zero lash and then a half turn more it's how that's done and I'll demonstrate that here in a minute but you want to rotate the engine around and I'm just doing this just to see stuff at

The moment how stuff is moving the valves are opening oh yeah I was afraid of that so back these off we're gonna go through one cylinder at a time and probably the easiest way to convey this to you is I'm

Gonna start here at number one cylinder the minute one valve starts to open so the minute one belt starts to move you can adjust the other one so we'll keep an eye on these two and look for one of them to move okay this guy's starting to

Move so this guy's on its base circle so we can adjust that one to perform the adjustment spin the push rod and also you want to make sure that the push rod is seating seated down inside the lifter and seated

Up inside the bottom of the rocker this is imperative because if you get this wrong well everything's gonna be wrong from there on out all right spin the push rod start cranking down the adjuster nut the minute the push rod

Stops moving then turn it 1/2 turn more so take this and go 1/2 turn past tight right there lock it down as far as the torque spec on these snug is great that valve is officially adjusted now we'll keep

Turning the engine over until this one starts to move and we know that this one's on its base circle there it is so we know this one's on the base circle same procedure let me just keep doing this on down the line looks like I had

To back these off just a wee bit more ok so spin it it's okay to do it a couple of times ok it's stopped moving right there zero lash count cam says to like move it up and down my machinist said spin it

Just gonna go right there something I want to drop in here real quick is that half turn adjustment I found not to be sufficient in fact a full turn is what I recommend on both the Ford and the Chevy I've used hydraulic roller lifters from

Comp cams and both engines and both instances I started things up after the fact with just the half turn adjustment and the valve train was noisy I had to go back and adjust the Ford to one full turn of adjustment I did the same thing

On the Chevy the Chevy ran for a little while got a little noisy at the top end I went back in and did that adjustment one full turn after doing that there been no issues and the top end has been quiet so my recommendation to you if

You're making this adjustment go one full turn not a half turn and if they're all looking the same that's a good sign if you got one of these that's way off scratch your head look at it let's do it again

Alright this whoops I broke it this one here just started to move I can tell because I can see the lifters on this side so I'm going to adjust this one next stop moving half turn

She's some of these like this guy right here I can't go a half turn something I've discovered is turn these like extra far out because when I went to tighten it before it was actually closing in on the lock but I know I'm on the base

Circle so spinning spinning spinning spinning it stops half turn OOP no problem that time by the way these are hydraulic it's a totally different procedure with solids solid valve trains you want to get it as

Good as you can but it's not like exact its hydraulics so there's a little bit of fluff a little bit of movement in there don't sweat like a couple thousandths of an inch going these be all adjusted now

Let's watch it work and listen it's got drawing air push it out well for those of you that made it this far thank you so much for watching as stated at the beginning of this video this video is actually taken out of a longer video

About the Assembly of the engine that I built for this 1990 C 1500 that's behind me I took the 350 though it was in it turned it into a 383 and well you saw at least the valvetrain component assembly that I did in this video the one real

Take away with this is when you're doing that adjustment go full turn instead of a half turn I installed pretty much the exact same components on my Ford engine and had the exact same problem when I went a half

Turn I ended up with a noisy valve train until I went back and did that adjustment at a full turn after that everything was hunky-dory and I haven't experienced any issues in either engine since they've been assembled as far as

Valve train noise is concerned that being said I'll put links in the description to additional videos information tools parts all that stuff that I use so please check the description if you have any questions

About things that you saw in this video also if you have automotive questions that weren't covered in this video I've got something for you and that's Eric the cargo calm also link down a description please like comment
