TM 5-3895-383-24 2. Make sure that the manual directional control valve (4) is in the neutral position. 3. Disconnect electrical connector (2) for the neutral start switch (1). 4. Clip the multimeter leads to the two pins in the electrical connector (2).  Switch the multimeter to the position that will measure continuity. 5. Loosen   locknut   (5)   that   is   holding   the   neutral   start switch. 6. Turn  the  neutral  start  switch  until  the  beep  from  the multimeter  cannot  be  heard.    Turn  the  switch  in  the counterclockwise direction until the beep is heard. 7. Hold the neutral start switch and tighten the locknut. Charge Relief Valve - Test and Adjust SMCS Code:  5117-025-PX; 5117-081-PX Table 13 Required Tools Part Number Description Quantity 8T-0855 Pressure Gauge 4000 kPa (580 psi) 1 Personal injury or death can result from sudden machine movement. Sudden  movement  of  the  machine  can  cause  injury  to persons on or near the machine. To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine. Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped.  Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool  before  removing  any  components  or  lines.    Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. NOTICE Care  must  be  taken  to  ensure  that  fluids  are  contained during  performance  of  inspection,  maintenance,  testing, adjusting and repair of the product.  Be prepared to collect the   fluid   with   suitable   containers   before   opening   any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose  of  all  fluids  according  to  local  regulations  and mandates. NOTE: A charge relief valve is located in both the propel pumps.  The charge relief valve in the drum propel pump should be the controlling relief valve (lower pressure   setting).      If   the   setting   for   the   drum charge   relief   valve   does   not   change,   the   axle charge relief valve may be set too low.
