hello hello my crx community and other viewers thanks for tuning in today we're going to be
assembling and measuring the lower rotating assembly on a d
series block this applies for almost every d series out there these are the main bearings
here and we're gonna go ahead and get these put in so i'm gonna clean this area out really well
and make sure it's dry and we're gonna do the preliminary fits right now with the plastic
gauge and everything so what i like to do is i'll wipe these off and these are alc race bearings
let's see if we can get that in focus there where's that
there it is standard race bearings so what i like to do is i'll wipe them off to get all the packing
grease off of them and then there's a little tang right here and what i'll do is i'll align
that tang in the groove there and i'll hold my finger on it and i'll push on the other side
and just slide it on in and what you want to do is you just kind of want to level it out
get it right to where it's setting nice and in the middle make sure they're all flushed out which
they are we got them all installed we're going to wipe the crankshaft off and lay the crank on there
and that everything like i said goes together dry because we're going to do a plastic gauge
check on the oil clearances so let me get the crankshaft wiped off and get it set down in here
okay we got the crank set down in there and as you can see i got the counterweights
pointed up and that's so that the oil holes are not straight up because you
want to get a flat piece of plastic gauge straight across you don't want an oil galley
messing it up or anything so now we'll get the rest of the main bearings in the crankshaft
girdle same process slide them in with the tang we'll set that down get this thing cranked down
okay we have the plastic gauge set up on there let's get this in focus if you see there
we've got a strip of green on each one of the main lobes
and we will place the girdle on very carefully and go ahead and tighten the girdle bolts down to full
torque spec like you were building the motor then we'll remove everything and check the clearances
okay we're trying to get it in focus here
okay so we set the crankshaft cap girdle whatever you want to call it onto the crankshaft and block
assembly tightened everything down with the plastic gauge and we got a reading so
the object and i know it's kind of blurry it's hard to get down in there me trying
zoom in and show you guys the specs are for this engine is point zero zero one three
two point zero zero two four and
that's what we're aiming for in this plastic gauge
go ahead and get down there real quick
all right if you see right there it's a smeared piece of wax it's squished out
and our measurement is zero zero one three to zero point zero zero two four so that's
0.0015 so a little bit less than that all the way up to this one and anywhere
in between would be good so we'll get down there see if we can get a good look at that
too bright
anyways you see you get the picture it's got to be between these two boxes and it is it's a
little bit smaller than the white box and it's bigger than the green box that's between .0015
and .0024 because that's point zero zero two and you would check the rest all the way across
now be aware sometimes some of the plastic age will stick to the girdle
side so check both sides and use your best judgment and now we have to check the rods
all right we got the bearings in we did the same thing lined up the tab put a little tang and slide
it on up we got the speed factory no notch rods for d series we're going to do the same thing put
a strap of plastic age across the journals tighten everything down the spec and check them okay i'm
not sure how good this is getting it but the specs called for no more than point zero zero two
so we're right at about point zero zero one five so we're well with inspect for the rods
so do that and check for the rest your rods and then you'll be ready to assemble the lower end
