7. Inspect wheel tie bolts for cracks, bending, thread damage, or excessive corrosion, any of which is
cause for rejection.
The tie bolts are subjected to fatigue type loads and should be replaced whenever there is any
question as to their serviceability.
8. Test the wheel tie bolt nuts by installing them onto the bolts. If the nut can be turned by hand past the
self-locking section, it must be replaced.
9. Inspect brake disc for excessive wear, scoring, or corrosion, cracks, warpage, or other physical damage
which is cause for rejection of the part. Replace the disc if the disc thickness has worn more than
0.025” from new.
These dimensions can be found by visiting www.groveaircraft.com
Minor corrosion and surface irregularities can be blended using 220 grit sandpaper
Any corrosion on the non-braking part of the disc should be removed and then painted and/or treated
for corrosion resistance
Reassembly of Wheel
Reassembly of the wheel is basically the reverse of the disassembly process. Assemble the wheel on a clean,
flat surface being careful to not nick, scratch, or damage the protective finish of the wheel
Reinstall the Bearing Races
Conduct if applicable. Heating the wheel and/or cooling the bearing race is of minimal benefit in the installation
process
1. Clean the wheel bearing race bore and apply a thin coat of wheel bearing grease
2. Place the bearing race in the wheel bore, being careful to ensure that it is aligned properly and not
cocked
3. Place the wheel half in the press as shown in the following figure being sure to support the wheel half
at the bottom of the bearing seat. Failure to do this may result in breakage of the wheel casting if too
much force is applied
4. Press the bearing race into the wheel until it is fully seated
5. Remove the wheel from the press and visually check to see that the race is fully seated and that it is
tight in the wheel
Mount Tire on Wheel
1. Ensure that the wheel is clean and dry. Particular attention should be paid to the bead area to ensure
that it is clean, dry and free of grease or other contamination which may cause the tire to spin on the
wheel as the brakes are applied.
2. Replacement tires: 5.00-5 10-ply
Rated Load: 2150 lbs.
Rated Speed: 120 MPH
Replacement tube: 5.00-5 tubes with 90° valves
Insert the inner tube into the tire. Align the red dot on the tire (its lightest point) with the white or
yellow dot on the tube (its heaviest point). If the tube does not have a white dot, align the red dot on
the tire with the valve stem of the tube. In order to allow the tube to move freely within the tire, it is
recommended that you coat the tube and inner part of the tire with talc powder.
3. Inflate the inner tube to approximately 10 psi, allowing it to take the shape of the tire
Deflate the tube to the point that it just retains its shape.
4. Place the tire and tube onto the outer wheel half carefully inserting the valve stem through the hole in
the wheel half.
5. Insert the inner wheel half into the tire with the tie bolt holes aligned and using care not to pinch the
inner tube.
6. Place the wheel and tire assembly on a flat working surface with the inner side of the wheel facing up.
Install the brake disc in the inner wheel half and align the bolt holes with the wheel half. Insert the tie
bolts through the brake disc and wheel.
7. Rotate the wheel from the working surface in order to be able to attach the nuts to the tie bolts
Hand-tighten a nut with washer on each of the tie bolts. Care should be taken to ensure that the wheel
halves are in contact with each other and not pinching the inner tube.
