Item Nomenclature
T101 Ground Handling Wheel Set
The ground handling wheel set (T101) consists
of two each dual wheel assemblies, which
support a fully equipped MD Explorer approxi
mately three inches above the ground.
The Wheel Assembly consists of two pneumat
ic tires, rims, spindles, a main frame body,
hydraulic jack, and attach cradle.
B. Tires
The Wheel Assembly has two 14 inch diame
ter, 500 x 5 Cleveland with 10 ply, 65 psi
Goodyear tires mounted on steel rims, with a
load rating of at least 1120 lb at 35 mph.
(1). At regular intervals examine tire
pressure and inflate to 65 psi.
(2). Inspect tires for wear and cuts, none
allowed.
C. Steel Rims
The steel rims rotate on a spindle by means of
an inner and outer tapered roller bearing with
an external grease fitting on the hub for
periodic servicing.
(1). Inspect wheels for cracks and defects,
none allowed.
(2). At regular intervals (yearly) repack
wheel bearings.
D. Main Frame Body
The main body is a rectangular box frame
weldment constructed from 1/4 1020 steel
plate.
E. Hydraulic Jack
A six ton jack is held in place on the main
frame by a support plate.
The jack retains a vertical position, during
raising and lowering of the wheels.
The ram of the hydraulic jack is in constant
contact with the upper cross frame of the main
body, providing vertical pumping leverage
forcing the spindle and wheels down.
(1). At regular intervals (yearly) inspect
hydraulic jacks for proper fluid levels.
F. Attach Cradle
Permanently fixed to the bottom of the main
body is a slotted lock down cradle. The cradle
is constructed from 3/16 steel plate and is
contoured to conform to the MD Explorer skid.
