Caterpillar aftermarket solenoids
Solenoids turn electric power into mechanical work. By generating a linear electrical magnetic
field that interacts with mechanical components, solenoids help in closing and
opening internal valves, or setting off chain reactions to monitor other
mechanical circuits.
Solenoid construction consists of a thin copper wire wound around a steel plunger. When the power
turns on, the magnetic field activates to pull the plunger back in. If the
exposed end of the plunger contacts another segment of equipment, the solenoid
effectively acts as a start-stop mechanism for the circuit that equipment
handles.
Many solenoids feature dual-coil construction, with one coil regulated the push or pull of the
surrounded plunger, and another controlling the hold function.
Caterpillar solenoids manage several important functions in automotive and diesel engines:
• Run-stop levers: Automatic shutdown and restarting of internal combustion engines while idling to conserve fuel
• Chokes: Managing air and fuel mixture to work in a cold engine
• Throttles: Regulating air-fuel fusion to manage speed and engine air supply
• Clutches: Controlling the starter motors in cars with manual transmission
• Fuel valves: Restricting fuel valve opening to protect damage from high speeds, hot temperatures, and low lube pressure.
Diesel engine solenoids are especially important to keep maintained. Solenoids protect diesel
engines in situations involving high speed or other risky conditions by
restricting fuel flow to the engine's injectors. An outdated or defective
solenoid in a diesel engine’s fuel valve system imposes limits on its power and
speed, which can require emergency measures with the clutch and brake system to
stop the engine. It’s vital to ensure that a diesel engine’s solenoids are
sufficiently connected to power sources to keep them operating efficiently.
PJ Power uses quality Caterpillar aftermarket solenoids as an alternative to original equipment manufacturer parts.
Caterpillar aftermarket solenoids offer a solution for those looking to replace
individual engine components at considerable cost savings.
Contrary to public perception, aftermarket solenoids are not used. They are newly produced
products using components developed by and sourced from established solenoid
companies, like Caterpillar and Woodward.
Since construction integrity is a major concern about aftermarket products, PJ Power takes extreme
care in making sure the aftermarket solenoids are being manufactured to precise
detail. The manufacturer follows strict and precise procedures, as guided by
product specifications outlined by Caterpillar or Woodward. Aftermarket
solenoids are built to be compatible with OEM parts as much as possible, and
PJ Power uses the same kind of Caterpillar-manufactured components to reconstruct
solenoids with optimal structural integrity and performance.
