Rear tire off a Case backhoe after repair.A flat tire can shut
backhoe work down and cost a lot of time and money to fix. Here
are some steps to help you fix it yourself if you don't have time
or the money to call in professional help.
!! Steps !!
Ensure safety first. Always support any vehicle safely when removing
or installing wheels.
* If possible, get a helper. Tractor tires are heavy to work with.
If you're able, get assistance.
* Be conscious at all times that pry bars can slip and cause serious
injury. Use with great care.
* _ Using the backhoe stabilizer to raise the flat tire off the
ground. Prying the tire off the wheel with a tire iron.Lift the
tire off the ground. On a backhoe, the stabilizer can be used for
this job on rear tires, or the loader bucket will do for front
wheels.
* Using a pneumatic impact wrench to take out lug bolts.Remove
the lug bolts. Using a pneumatic impact wrench can speed up this
process.
* Remove the wheel from the tractor and lay it down on level ground
(if possible).
* Using the backhoe bucket to press the tire off the bead.Press
the tire off the wheel inner rim bead so it can be taken off. With
a backhoe, you may be able to complete this step with the digging
bucket. If necessary, use a tire hammer to break the tire's beam
loose.
* Flip the tire over and break the bead loose on the outside of the
wheel.
* Using a block of wood to lift the tire so it will rise up free
of the bead when pried off the wheel.Place a support on the side
of the tire. Use a wood block so the tire will rise up from the
rim as it's pried off.
* Using a tire iron to pry the tire off the wheel.Use a tire
iron or a pry bar to pry the tire's bead off the rim. Start near
the valve stem and work around the tire, heading *away* from the
stem to keep from pinching it.
* Here the tire bead is completely off the rim.Continue to work
around the tire until the whole tire is pried off the rim. Then
block the tire up higher so the tube (if the tire has a tube) can
be removed.
* Removing the tube valve stem locknut.Remove the valve stem and
stem locknut from the tube.
* Pull the tube out of the wheel beginning at the valve stem and
working around the rim.
* Here, the inflated tube sits on top of the tire aligned so
damage can be observed in the tire.Place the tube on top of the
tire so it is in the same position it was in when it was inside
the tire. This will allow you to look for problems with the tire
itself when you locate the leak in the tube.
* Inflating the tube to look for the leak.Replace the valve stem
and inflate the tube so you can look for the leak. Using a spray
bottle with soapy water will help you find small punctures, but
obvious damage may not require this technique.
* Deflate tube and place it on a comfortable, flat working surface.
A truck tailgate or a worktable is good for this.
* Tire repair patch and tire boot for sidewall repairs.Get out
(or go purchase) your patch kit. Make sure you know exactly where
the damaged spot on the tire is, then buff an area with a buffing
tool to roughen up the rubber. Work around the puncture or damaged
location so the patch will fit within the roughened area.
* Using a buffer to roughen the tube for the patch.Apply rubber
cement to the area you've buffed, then wipe off the excess glue.
Allow it to dry until it's no longer glossy. Do not wait too long
to apply the patch, or the glue may completely lose its adhesion.
* Peeling the protective cover off the adhesive side of the
patch.Peel the patch backing material off the patch. Take care not
to touch the surface of the patch underneath it.
Placing the patch over the damaged spot on the tube.Place the
patch over the damaged spot on the tube, being careful not to
allow it to wrinkle.
* Push the patch or roll it with a patch roller to make sure it's
well bonded to the tube.
* The inside of this tire's sidewall needs repair before the
tube is replaced.Check the sidewall near the location where the
tube was damaged before replacing the tube. You may find an old
nail, wood splinter or other object still embedded in the tire, or
you could see a damaged area that will need attention before
replacing the tube.
* Boot installed inside the tire.Install a boot_ on any large
holes or split sidewall areas of the tire. This will prevent the
tube from being damaged when the tire is reinflated.
* Reinstall the tube in the tire. Make sure the valve stem is
aligned with the hole in the rim where it will fit. Push the valve
stem through the hole made of it, and replace the retaining nut
that will hold it in place as the tire is remounted on the rim.
_ Prying the tire back onto the rim with a tire iron.Use your
tire tool or pry bars to pull the tire back onto the rim. Start
near, but not directly in line with, the valve stem, then work
around the rim moving away from the valve stem to prevent
pinching the tube.
* Continue around the tire until it is reinstalled completely on the
rim.
* Replacing the valve stem in the tube after the tire has been
remounted.Replace the valve stem core and inflate the tire. You
will hear air escaping from the cavity between the tube and tire
as the tube inflates, but don't worry about it, as this is normal.
* Watch the tire's bead as it rides up the rim so it is centered
properly on the rim.Make sure the tire's bead is in line with the
edge of the rim as the air pressure forces the bead into place on
the rim. This will help prevent a blow-off_, where the air
pressure might accidentally blow a part of the tire off the wheel
assembly.
* Aligning the lug bolt holes with the rim so the bolts will go
in straight.Lift the tire back up and roll it close to the axle
hub where it will be mounted. Adjust the height of the tire so the
wheel will fit the hub, then align the lug bolt holds and install
the lug bolts.
* Using the impact wrench to tighten the lug bolts.Tighten the
lug bolts securely. To make sure the wheel fits the hub properly,
criss-cross the hub tightening bolts across from each other rather
than working a circular pattern.
* Using an air chuck with a built in gauge to inflate the tire
completely.Check the tire pressure with a gauge. Let the tire back
on the ground, and clean up your tools.
!! Tips !!
* Standing, or having someone stand on the tire bead will make
removing it easier.Pressing down on the tire on the opposite side
from where you're prying with the tire tool will give you slack to
make removal easier.
* Wiping lubricant on the tire bead makes installing the tire
easier, and helps the bead to seat properly.Lubricate the tire
bead before reinstalling it. Do not use a petroleum based
lubricant, as it may cause the tire rubber to deteriorate.
* Using a torque wrench will insure the lug bolts are adequately
tightened.
!! Warnings !!
* Here, the tube was pinched, but not damaged during
removal.Take care not to pinch the inner tube when removing or
reinstalling the tire.
* Tractor tires are heavy to work with. If you're able, get
assistance.
* Pry bars can slip and cause serious injury.
* Rubber cement may be extremely flammable.
* Always support any vehicle safely when removing or installing
wheels.
