I'm super stoked if you've been following this tracker project we're
gonna wrap this thing up we're going to have this Cummins engine blowing some
smoke
before we install this head let's talk about its gasket there's three common
ways that you can blow a head gasket so if you've got a puddle of antifreeze
underneath your car and your mechanic coaches its your head gasket it's
because your head gasket is allowing your coolant to leak externally or if your
car is overheating due to a blown head gasket chances are you've got a leak
between your cylinder and your cooling system if your car is running bad due to
a blown head gasket you're leaking between two cylinders like all the other
bolts in this engine we'll make sure we litigate the threads and the shoulder
and we'll torque them to the manufacturers specs
it's i mportant to follow the manufacturers set patterns on the head
bolts when torqueing them so we've got our head bolts torqued to three hundred
foot-pounds we're gonna go another 90 degrees well I want its impact gun we're
gonna lubercate the cam bearings and slide the cams in
okay so we've got our cams installed the next step is to set the cam timing
and it's very important to set your cam timing properly because you've got six
Pistons running up and down you got 24 valves over top of those Pistons and if
those things aren't in sync you can have major engine damage we've got two types
of cam timing gears you've got a fixed gear and you've got a tapered gear like
this typically a fixed gear you'll align with timing marks on the gears this
particular engine you're going to use a timing wedge instead what you do is you
slide this down there's a flat spot in the cam it's gonna lock that cam in
place where the factory wants it to be boom your topsides done it's time to
move on to the crankshaft so setting the crankshaft timing position is pretty
simple there's a hole in the block I have a timing pin I'm gonna slide this
into the hole in the block I'm gonna rotate the engine slowly until it finds
a hole in the crankshaft so before we started this procedure we intentionally
left these cam gears loose that allowed the gear to slip on the cam so with our
crankshaft lock down and our cams lock down now we can lock these gears down
our engines in time alright so we've got our bolts laid out and organized our next step is
to install the rocker assemblies
the next step is to install the engine oil cooler but first we're going to take
this coolor apart we're going to take it over solvent tank and we'll make sure
there's no debris left in that cooler
so when this engines running this entire jacket right here is going to be
completely full engine coolant that coats going to circulate through these
oil coolers and cool the engine oil now I've ever seen a fuel pump but this
right here is an enormous fuel pump you got a lift pump you got actuators that
supply the injectors and they've got a fuel shutoff valve it's time to install
the turbo if you're not familiar with the turbo the turbos job is to enable
your engine to burn the maximum amount of fuel exhaust heard is the turbine
side of this turbo it turns a compressor side force feeds your engine with air
and oxygen that allows it to burn more fuel it's also important to pre
lubricate these turbos you never know if I've been pre levitated from the factory or
not it's time to install the lubrication system this is the engine oil pump and
it's very important to prime your engine oil pump especially if you've had it apart
okay so what we've just installed is a coolant manifold and the first episode
we talked about cavitation that could be treated with additive you screw the
cannister with additive it flows through protects your cylinder liners
all right so now it's time to adjust our valve clearance valve clearance is the
distance between our rocker arm and our valve bridge at low cam it's very
important to make sure that your clearance is set properly if it's too
tight your valve might not close you can learn
a valve up if it's too loose a bridge might fall off and fall down into your
engine so the objective here is to measure the distance between the rocker
arm nose pad and the valve bridge and for that we have a 14,000th feeler gauge
what we're going to do is slide that between the bridge and the nose pad and
it's going to tell us our clearance we're getting close let's get the valve
cover put on get our tractor pulled inside
that should do it. it's actually not a bad job now what we're going to do is hook
the driveshaft up we're going to bolt all the accessories on get the wires and
lines hooked up fill this thing with water and oil and make us some smoke
so we've got our engine filled with engine oil and coolant. next thing we
need to do is pre lubricate it we will crank the engine with the
ignition off and until we get oil pressure on this gauge
okay so that' should wrap-up our tractor project this thing's running good sounds
good got good engine oil pressure and if you like this comment below let us know if
