of the transmission       and extends into the driver’s compartment.
    d.             To supplement the gear ratio of the transmission,
a two-speed transfer       is mounted on the rear of the transmission.
The transfer      provides additional gear reduction for negotiating
difficult terrain, a power-take-off       for the winch, and a means of
transmitting     power to the front axle. The transfer             is manually
operated by the driver through a set of transfer             gearshift levers
on top of the transfer.        The levers extend into the driving com-
partment to the right of the transmission            gearshift    lever.
    e.                                   The front axle is a full-floating,
single-reduction-type       with hypoid drive gears. Incorporated               in
the front axle are constant velocity-type           universal joints at the
steering knuckles. A propeller shaft provides a connection from
the front axle to the transfer          for the transmission         of power.
Power through the transfer         is controlled by a transfer        gearshift
lever in the driving compartment.            Suspension of the front axle
consists of two semielliptic springs, shackled to the frame at the
front of the spring, secured to the frame at the rear of the spring
by pivot bolts, and attached to the front axle by U-bolts.
   f.                                   The rear axle is a semifloating,
single-reduction-type       with hypoid drive gears. The rear axle is
connected to the transfer        by a propeller shaft for the transmis-
sion of power. Suspension of the rear axle consists of two semi-
elliptic springs shackled to the frame at the rear of the spring,
secured to the frame at the front of the spring by pivot bolts,
and attached to the rear axle by U-bolts.
    g.                    The service brakes are actuated hydraulically
using full-floating     brake shoes. Service brakes are on all four
wheels and are operated by the brake pedal in the driving com-
partment.     The hand brake is a mechanical brake at the rear of
the transfer     and is operated by pulling the hand brake handle
outward from the instrument           panel. A ratchet holds the handle
in a locked position which can ‘be released by a quarter turn in
either direction.
    h.                         The electrical system furnishes           current
for ignition, lights, sending units, etcetera.            Current     is gener-
ated by a 24-volt, belt-driven generator, and stored in two 12-volt
storage batteries connected in series.

Section     II.   LUBRICATION      AND   PAINTING


66.    lubrication         Order
   Lubrication     Order 9-8012 (figs. 14 and 15) prescribes cleaning
and lubricating      procedures   as to locations, intervals, and proper
materiels    for this vehicle. The official lubrication      order will be
carried with the vehicle at all times. In the event the vehicle is
received without a copy, the using organization         shall immediately
requisition    one. See DA Pam 310-4 for lubrication         order of cur-
rent date. Lubrication        which is to be performed        by ordnance
maintenance      personnel is listed on the lubrication       order in the
“NOTES”       (fig. X), and in a few instances are contained in the
pertinent   section.

67.    General       Lubrication     Instructions
     n. Gencml. Any special lubricating  instructions  required for
specific mechanisms or parts are covered in the pertinent sections.
    6. Usual Conditions. Service intervals specified on the lubrica-
tion order are for normal operation        and where moderate     tem-
perature,     humidity, and atmospheric   conditions prevail.
    c. I,ub7ication Equipwent. Organizational     maintenance tdol sets
contain lubrication     equipment adequate for maintenance.      Clean
this equipment both before and after use. Operate the lubricating
guns carefully and in such a manner as to insure a proper dis-
tribution of the lubricant.
     d. Points    of Application.
        (1)   Lubrication   points are shown in figures 16 through 19
              and are referenced    to the lubrication order. Clean fit-
              tings and surrounding    surfaces as prescribed  in lubri-
              cation general notes (fig. 14).
        (2) A :jI,<-inch red circle should be painted around all lubri-
            cating fittings, oil can points, and refill plug holes.
        (3) Clean and lubricate unsealed bearings as in (a), (b),
            and (c) below.
          (a)    Wash all the old lubricant   out of the bearings and
                 from the inside of the hubs with volatile mineral
                 spirits or dry-cleaning  solvent and dry the parts
                 thoroughly.
                    Cnutiorc: Bearings must not be dried or spun with
                  compressed air. See TM 37-265 for care and mainte-
                  nance of bearings.

50                                                                   AGO   10167B

all of these checks that are pertinent to any item (including sup-
porting, attaching,      or connecting      members)      will be performed
automatically,      as general procedures,      in addition to any specific
procedures given.
       (1) Inspection for “good condition” is usually visual inspec-
            tion to determine       if the unit is safe or serviceable.
            “Good condition” is explained further           as meaning:      not
            bent or twisted, not chafed or burned, not broken or
            cracked, not bare or frayed, not dented or collapsed, not
            torn or cut and not deteriorated.
       (2) Inspection of a unit to see if it is “correctly           assembled
            or stowed” is usually a visual inspection to see if the unit
            is in its normal position in the vehicle and if all its parts
            are present and in their correct relative positions.
       (3) Inspection of a unit to see if it is “secure” is usually a
           visual, hand-feel,     pry-bar,    wrench, or screwdriver          in-
            spection for looseness in the unit. This inspection will
           include any brackets,         lockwashers,      locknuts,    locking
           wires, and cotter pins as well as any connecting tubes,
           hoses or. wires.
      (4) “Excessively      worn” is understood to mean worn beyond
           serviceable limits, or likely to fail if not replaced before
           the next scheduled inspection. Excessive wear of mating
           parts or linkage connections is usually evidenced by too
           much play (lash or lost motion). It includes illegibility
           as applied to markings,         data and caution plates, and
           printed matter.
      (5) Where the instruction          “tighten”    appears    in the pro-
           cedures, it means tighten with a wrench, even if the
           item appears to be secure.
      (6) Such expressions       as “adjust if necessary”         or “replace
           if necessary”    are not used in the specific procedures.           It
           is understood that whenever inspection reveals the need
           of adjustments,     repairs, or replacements,       the necessary
           action will be taken.

74. Cleaning
   a. General.  Any special cleaning instructions    required for spe-
cific mechanisms or parts are contained in the pertinent          section.
General cleaning instructions    are as shown in (1) through            (5)
below.
      (1) Nameplates,   caution plates, and instruction     plates made
          of steel rust very rapidly. When they are found to be
          in a rusty condition, they should be thoroughly         cleaned
          and heavily coated with an application of lacquer.
                                                                      AGO   10167B

                          and inspect spark plugs (par. 145). In-
                          spect distributor cap, rotor, and breaker
                          points and test operation of centrifugal
                          and vacuum advance mechanism by hand.
                          Test distributor shaft for looseness by
                          hand feel. Test ignition coil and distribu-
                          tor capacitor with high-tension ignition-
                          circuit tester, if available, according to
                          instructions accompanying the test instru-
                          ment. Using neon timing light, observe
                          if ignition timing (figs. 58 and 59) is
                          correct (par. 142) and if spark advances
                          automatically   as engine is accelerated.
                          Test generator regulator with a low-volt-
                          age circuit tester following instructions
                          accompanying the test instrument.

                           145). Check distributor    breaker points
                           and adjust gap (par. 143), (figs. 57 and
                           61). If points are badly pitted, repIace
                           both points and capacitor.

                          items. Look particularly    for signs of
                          leakage at manifold gaskets. If heat con-
                          trol is automatic, see if shaft operates
                          freely and if bimetal spring controls it
                          properly. If it is manually controlled,
                          check seasonal adjustment.

                                     lines. Inspect these items notic-
                          ing particularly if the shafts and linkage
                          operate freely and are not excessively
                          worn. Observe if the choke valve plate
                          opens fully when the choke control is
                          released and if the throttle valve plate
                          opens fully when the accelerator is fully
                          depressed.

(‘3) Faulty engine vacuum. Peform         engine vacuum test as
             follows-disconnect        fuel and vacuum pump vacuum line
             at elbow located on exhaust manifold, and install vacuum
             gage adapter in elbow (fig. 22). Start engine and run
             at idling speed until minimum operating            temperature
              (160” F.) is reached. Make sure the carburetor           is ad-
             justed properly.     Adjust if necessary     (par. 127). With
             engine operating       at normal idling speed, vacuum gage
             should show a reading of 18 to 21 inches of mercury. A
             pointer fluctuating      between 10 and 15 inches of mer-
             cury may indicate a leaking valve or defective cylinder-
             head gasket. An abnormally low reading with the pointer
             steady may indicate a leak at the carburetor.        Accelerate
             and decelerate engine rapidly. Vacuum should drop to
             approximately      2 inches of mercury with rapid accelera-
             tion, and should rise to 24 inches of mercury as accelera-
             tion is decreased quickly.
                Note. Above readings are for sea level operation. Vacuum read-
             ings will be lowered approximately i inch of mercury for 1,000
             feet increase in altitude.

          on the end of the line into the fitting in the cover.
          Start the engine and run it for a few minutes to fill
          the oil filter assembly and check for oil leaks around
          the flexible oil line connections and the filter.
             Note. The oil filter inlet flexible oil line is slack enough to
          permit the engine fan blast to force the line into constant contact
          with the manifold elbow. To prevent damage by burning, move
          the oil filter clockwise within its mounting bracket to shorten
          the line enough to keep it clear of the manifold elbow.


      (1) Disconnect the oil filter inlet flexible oil line assembly
          and fitting from the oil filter head with cartridge as-
          sembly by unscrewing the nut from the fitting and un-

       (8)    Make a record of replacement      on DA Form 478.


       (1)             The cooling system      (fig. 39) is fully sealed
           and pressurized.    The system consists of a water pump,
           water pump bypass, fan, drive belts, radiator,         thermo-
           stat, and connecting hose. Water is drawn down through
           the radiator    to the bottom thence through        the water
           outlet hose to the water pump which forces it through
           the cylinder block, cylinder head, and the water inlet
           hose to the top of the radiator. Air, for cooling the water,
           is drawn through the radiator by the fan. Correct op-
           erating temperature      is maintained    by the thermostat.
       (2)                       and 32). The radiator is the cellular-
           type, with upper and lower tanks. The filler cap has a
           spring-loaded    seal to maintain     a pressure  of approxi-
           mately 4112 psi when the engine is running. The cap seal
           acts as a safety valve by lifting off its seat to relieve
           excessive pressure.

type, sealed at all control and adjustment     points. The
      float chamber is also fully sealed. The carburetor      as-
      sembly is mounted over the center of the intake manifold.
(4)                                       The fuel and vacuum
      pump is the diaphragm-type,   providing constant        of
      fuel to the carburetor  when the engine is running. The
      vacuum pump is incorporated     to assist the windshield
      wiper motor action. The pump used in early model
      vehicles was equipped with a hand priming lever for
      manually pumping fuel to the carburetor.
(5)                          (P, fig.       The fuel shutoff valve
      is located at the left of the steering gear assembly. This
      valve shuts off the fuel supply from the fuel tank to the
      fuel pump.
(6)                                   The fuel tank is located on
      the left side of the vehicle, under the driver’s seat. The
      filler cap is located in a recess in the left side of the
      body panel. The fuel tank level sending unit assembly
      is located on top of the fuel tank. The fuel filter assem-
      bly is located in the top of the fuel tank. The fuel tank
      is equipped with a relief pressure          valve which will
      permit pressure to build up in the tank to a maximum
      of 4 psi. The cap (fig. 5) is a solid-type pressure cap de-
      signed for        only with this vehicle and should not
      be interchanged    with the vented-type    pressure cap, used
      with s/h-ton trucks, which open and release excess pres-
      sure. The solid-type cap used with truck M38 (fig. 5)
      has a cup about 31/2 inches in diameter,         inside of the
      shell, with a rivet in the center of the cup and a safety
      chain           about 1 inch off center. The vented-type
      filler cap used on the $&-ton trucks is of a spoke-like
      design, has a 31/2-inch diameter cup inside the cap with
      a vent hole approximately      r/!-inch in diameter     in the
      center, and a fastener              out to which a chain clip
      is attached. The cap used on the truck M38 is marked
      either embossed letters or decalcomania         with the word
      pressurized   and instructions    to open slowly while the
      vented-type   cap is stamped with the words PRESSURE
      CAP.
(7)                                   Fittings and solid and flex-
      ible lines connect the various parts of the system. Vent
      lines from the fuel tank and carburetor      are connected
      directly to the air cleaner assembly.
