328388-98X | Genuine Chelsea® PTO Air Shift Control Install Kit

1. Convenience & ease of use

• No climbing under or reaching awkward levers
• Just flip a switch or push a button
• Especially useful for frequent PTO use (like dump trucks)

2. Improved safety

• Driver can stay in the cab while engaging/disengaging PTO
• Reduces risk of injury from moving parts
• More controlled engagement

3. Faster operation

• Air systems respond quickly
• PTO engages/disengages almost instantly
• Saves time on repetitive jobs

4. Remote operation capability

• Can be set up to control PTO from:
  • Inside the cab
  • Or even outside (with additional controls)
• Useful for equipment like tow trucks or cranes

5. Better integration with modern trucks

• Many trucks already have compressed air systems (like air brakes)
• This kit uses that existing system, making it efficient

6. Enables automation (in some setups)

• Can be tied into:
  • Interlocks (e.g., PTO only works when parked)
  • Electronic controls
• Helps prevent misuse or damage

1. PTO won’t engage at all

• You flip the switch… nothing happens
• Could be:
  • Bad air valve
  • Leaking air lines
  • Failed air actuator

2. Slow or delayed engagement

• PTO eventually kicks in, but lags or feels sluggish
• Often caused by:
  • Weak air pressure
  • Partially clogged air lines
  • Worn air cylinder

3. Air leaks (very common)

• Hissing sound near lines, fittings, or valve
• PTO may:
  • Engage weakly
  • Disengage randomly

4. PTO disengages on its own

• PTO turns off while in use
• Usually caused by:
  • Air pressure dropping
  • Faulty control valve
  • Leaking actuator

5. Stuck engaged or stuck disengaged

• PTO won’t turn off or won’t turn on
• Possible causes:
  • Seized air cylinder
  • Dirty or stuck valve
  • Internal corrosion

6. Clicking or weak actuation sounds

• You hear the valve activate, but PTO doesn’t fully engage
• Means:
  • Air is reaching the system, but not enough force
  • Internal components may be worn

7. Switch works but nothing happens (electric-over-air setups)

• Dash switch lights up, but no PTO action
• Could be:
  • Bad solenoid valve
  • Wiring issue
  • Failed air control valve

8. Inconsistent hydraulic performance

• PTO engages, but:
  • Hydraulics are weak
  • Equipment runs inconsistently
