all right i wanted to make a video showing the different styles of thrust bearings and how to
install and properly set uh each of the popular styles so i'm going to go through the showing
you what the different bearings look like and the process of installation check it out
okay so here we have the most common style of trust that you're gonna find
in your early you know domestic v8s this is an ls uh so obviously more modern stuff but like
small block ford big black forward small black chevy big black chevy they all have this style
flame style thrust where the thrust surfaces are part of the main bearing surface
in the later generations of stuff like the uh say the coyote are in multiple different import
versions you have half the thrust is your standard style where the thrust surface is attached to the
bearing surfaces here and then on the other side you have this floating thrust surface
this will just lay in the block i'll show you a video how that lays in the block on the coyote
here in a second uh so your goal when setting the thrust specifically when you have two halves
right like this is to make sure that when you install these the reason you got to do
this is you want to make sure they are lined up perfectly in this direction you don't want them
to be offset by a couple thou you need them to be perfect and how you achieve that is by moving
you know you torque how i do it i torque all the bearings i'll loosen the the bearing cap that the
thrust bearing is on um we'll just you know like i said torquing it so it's set free
it up and then we'll move the crankshaft back and forth the idea is is that the surface the
thrust surface of the crank will align these two bearing hands now in something like the
the uh coyote here um you have to align obviously this is only on one half of the
one side of the bearing there isn't another half of this it is one thrust surface this is typically
on the flywheel side of the engine uh so what happens is you're only aligning this with the
back half so you only have to push the crankshaft in one direction to get this bearing half in the
correct location uh to line up with this when it's pressed against the block that's your
your goal is to press this against the block and have this pressed to the same spot so that
they're aligned perfectly when installed and that cap is torqued for the final time same process
just different deal so those are the two common tile styles of thrust bearings we see in here
i'm gonna go ahead and throw this crankshaft in this coyote and show you how to set it actually
before i do that i'm just going to show you real quick how this straw surface sits in the
block on the coyote they sit right in the back and it's literally gonna oh if i don't drop it first
hold on sorry it sits right there so it's got a tang the tang sits on that side of the block
to stop it from spinning and it just sits there uh i'd be i'm always sure to oil these surfaces
on both sides of the bearing both the thrust surfaces before i install it but you get the
idea that this sits in the block like so and it floats in there and you're trying to line
that surface up with the surface of the the thrust surface of the bearing that's in the cap
so i'm going to go ahead and fill this crankshaft in here and show you how i do that part
okay so now that i've got the crankshaft in and torqued and the rear main which the remain on this
one is the uh thrust bearing right so i've got that untorqued i've got my dial indicator set up
um i'm going to try to get a shot of this thing without all the glare on right here
um but it's moving that's zero it's moving i know it's hard to see this right so bear with me but
it's moving three thou right now i haven't put a a pry bar or hit it with a hammer some people will
do that obviously again referring to our previous video before the prank was in this um the thrust
bearing is only half on this it's a floating bearing on the block side uh which means we only
push the crankshaft in one direction when setting the thrust so if you move it both directions
you're really not accomplishing anything other than moving the thrust surface on that bearing
potentially in the wrong direction so you got to make sure you push the crankshaft forward
uh pretty much every time so i'm going to
do that uh real fast and then i will show a video of the after
okay now that i move this thing around with a pry bar
check this thing out it's not zero right now gosh that glare is horrible here maybe that'll
help okay so if i pull it forward we get about one negative push it back or three the other direction
so it's moving forth now so we moved it without a foul which means there was just a foul offset
from when that blockside thrust bearing was flat against the block to where the the captured or
whatever the flange thrust bearing was on the main campsite i'm really struggling to talk
um but that's that's how you set these up the dial indicator on it check it record your number
um you know for your notes and then go from there
all right you saw how i did the coyote thrust with the uh with the pry bar uh this one i'm gonna do
it a little bit differently um i'm gonna show you uh basically that it doesn't move now this
thing has a horrible glare i know so just watch the dial indicator that try to move this thing
nothing it's literally not moving
half a thou maybe save recorded without anyway nowhere near enough uh so what i'm gonna do with
this is a little bit different than the pry bar thing i'm gonna do this actually with a hammer and
this this is a plug just a block of nylon basically just a cushion
obviously you don't want to hammer against the end of the crank with a hammer that would be
dumb uh so we're gonna use this sometimes i use i have like a like an all plastic uh dead
blow that i'll use for a cushion i'll hit that dead blow with another hammer
um but uh not you saw that zero i've already got these caps torqued and the thrust one
loose so i'm gonna smack this thing a couple times and then i will show you the dial indicator again
obviously i have to pull it off to do that so i'm gonna do that all right so rather than doing a
time lapse of this one because it's just gonna take me a minute let's go with the camera roll
you can hear it sound different if i can pick that up in the camera but one more time just to be good
let's set the indicator back up here the reason i typically prefer doing the pry r over the hammer
thing is just it's way less violence right which is uh just i just prefer that this way
does work and it is common practice so i thought i would be just demonstrate demonstrated because
it was something you guys might want to see all right so now that i've done that check this out
got what three and a half foul so right on the right on the money there for where it needs to be
so i'm going to go ahead and torque the mains all that or the center main down again
and call this thing good so that's uh ran through the thrust setup on both the
coyote which is a floating thrust half and then ls which is not a floating half like
you saw earlier in the video so if any questions on how to set the thrust up
um just leave me a comment or if you want to see videos on different ones like some of the
specifically mitsubishi seven bolts where the whole cap the whole cap slips a girdle
and you gotta move that whole girdle to set the thrust correctly which often gets messed up and
is usually why they have crank walk issues so i could do a video on that if you guys would like
if you want that uh please just comment on the video and i will make it happen thanks for
watching
you
