so following through the procedure now do inspecting check warning clearance
for the and play in the bottom end of the engine
we need to use his diary indicator we have a magnetic base
we have the apparatus arms and here's the link an adjusted to set it on to the
engine
and then we have a diary indicator
that can read the value that we're looking for and we will
people look at that in comparison to manufacturers specifications
now the subtle box here campaigns for us
a bunch of the areas links and various hands
configuration of bands
that will help us
do the measurement process we can adjust all this onto the and of the dial
indicator
so that we have the crack
to be able to get into the block
warner an appropriate position to actually do the and play measurement
the eventual they can be used
there are fewer gauges
duffy litigators
their as accurate as a person that using them
and again the term philippines determinism
technician that's actually doing the work
so my ten thousand clearance
mayfield tighter or lucerne to another technician
it all determine its all determined by the technician that's actually doing the
measurements and the process that he
but here's to you
island every application of using a feeler gauge whether it's points
top and setting and thrust setting can then float setting
and a bunch of various other ones i mentioned
case of taking the dial indicator magnetic base
putting in an appropriate position on the block
and then
blocking the magnet
and then positioning the dial indicator
so that we have
a positive and negative reading
so that i can read it sakhalin
i'm looking to attain and that's crankshaft
and float clearance
so we'll take a look at the measurement
that or the clearance that i am trying to establish in a moment how in moving
the crankshaft first thing i want to do is just move it back and forth so that i
couldn't make sure that might be due zero than if i get my deed right to zero
that we're going to move the crank back and forth
to determine how much clearance we have
perfect take a look at how far this is moved because this skill works in one
ten thousand seven-inch four point zero zero one engines
and we're reading just over
six
so we have six
to ten thousand so we have six valid and float and two ten thousands or point
zero zero six two inches
something so manufacturers specifications were taking a look at the
crankshaft and play where there were any inquiries that we have for permissible
and flow
the manufacture prescribes here that they can be anywhere from six thousand
seven inch to a maximum of twelve thousands of image
so if we fall within that range
then we fall within the prescribed and float clearance
and i've already established through the measurement process
we have
six into tears
and for all intents purpose we can call the sixth hour
and we still have
unavailable
five innate tents or roughly another six hour of permissible amount of whereas
which allows these bearings to slowly where
increasing crankshaft envelope up to a maximum of twelve thousands of an inch
so when many fat when engines are manufactured in when engines are
rebuilt
we want to try to be here to the minimum end of the specification to get the
minimum running clearance
which provides a lot of longevity off
new and hopefully not beyond the maximum specification for that particular
measurement
kate checking the trade shaft and play one is a simple is using a screwdriver
to push back and forth on the train chapin if you notice any using a bit of
finesse
i'm not trying on it if i prioritized can actually meet increase clearance
measurement and i don't want to do that i just want to read
exactly what i have
based on train shot and
so now we're going to do is take a look at the position of the bearing in the
engine
and how we can actually do have a feeling beads measurement if you do not
have a diary indicator we take a look at the bearing itself we can see the
ended for thrust flanges on the split shell bearing
and we can actually see them
in position
on the engine here
end here
so what we want to do with v
feel icky jews is again that move the creature back
and then we're going to again move the creature
forward so that we have a clearance between the end of the crankshaft and
the thrust
way into the bay area
and the manufacturer says
six to twelve thousand
and we've established through the dial indicator measurement that we're around
six thousand seven inch
sulfite sets might feel irritated that states that wanted so taking a look now
with the purity we've established that we have a sixth hour of the and playing
running clearance
and we are about six and two tenths of just over six thousand civilians
so i'm gonna take my feeling each and here's what we drop it down in here
in between the end of the train chapter in the thrust bearing itself
begins that i have been there right now is six thousand it's bad a little bit
it's not miss duit it's got a decent dragged to it
but i'm going to say it's slightly larger dam
so we're going to go to put a seven gage in there and see how it fits and again
it's very close
so it's a good indication to me that with the dial indicator
that the six and two tenths of running clearances is the most accurate but this
is relative if we do not have
dial indicator to check the and clearance quickly taking a look at the
crank shaft
uh... site clearance abroad to crankshaft site clearance the
manufactures spec is twelve thousand plus or minus four and a half hour
so we have a wide range then we can fall within their to have the correct amount
of crankshaft side clearance on the connecting rod breaks a lot of the times
of technicians install bearings what they're looking for is clearings here at
all the connecting rods and you can hear on this one that we do have clearance
here's what we need to do is measured to find out if we have the correct amount
that's just seeing that we have some may not fall within permissible values
and the value we looked at the twelfth out plus or minus four and a half so we
can roughly run anywhere from around the foul
to around sixteen falafel ears
if i can get except where the manufacture prescribes it as a running
not at all about and that twelfth out
that's right like the set
so we take the feely gauge
which is
twelfth out
then we move the rod all over
and then
little bit of oil
we should be able to slide this down beside
the brought
and when it slides down in there we have no clearance and it's a good feel we
pull it out but it's a good indication that we have that value based on what
the fumigate strip indicates
son indicates twelve
falls right within the spectrum and looking for
so i can leave them
if it's too tight
the rocks need to be machine so they're slightly smaller
to increase the clearance
if it's too
tight or pardon me too small
that we may need to install either in new brought
or have the crankshaft machined and an oversized bearing or partner undersized
bearing
and and in connecting rod could get and reestablish the running clearance in the
engine
