Key Features of the 1987 JCB 3CX
- Powerful Perkins Engine:
The 1987 JCB 3CX was equipped with the Perkins 4.236 engine, a reliable 4-cylinder unit producing around 85 horsepower. Known for its fuel efficiency and low emissions, this engine made the 3CX a solid choice for operators needing a workhorse for extended hours in tough conditions.
- 4-Wheel Drive System:
The 3CX’s 4WD system gave it superior traction, allowing it to perform effectively in a range of environments—from construction sites with rough terrain to wet and muddy fields. This system is part of what made the JCB 3CX a standout in its category.
- Hydraulic System:
JCB’s hydraulic system is one of the cornerstones of the 3CX, providing ample power for digging, lifting, and trenching. The high-flow hydraulic system made it particularly efficient when using various attachments, such as augers, breakers, or grapples.
- Extendable Dipper Arm:
A hallmark of the 3CX was its extendable dipper arm, which provided greater digging reach compared to fixed arms. This feature allowed operators to work more efficiently without the need to reposition the machine constantly.
- Operator Comfort:
The 1987 JCB 3CX offered improved ergonomics over previous models, with a spacious cab, intuitive controls, and reduced vibration. JCB focused on reducing operator fatigue, making the 3CX a more comfortable machine for long shifts.
- Advanced Transmission:
The 3CX was equipped with a four-speed, mechanical transmission, providing versatility and allowing operators to switch gears based on load and terrain. The mechanical transmission was sturdy and relatively easy to maintain, further enhancing the 3CX’s reputation for longevity.
While the JCB 3CX is generally known for its reliability, the 1987 model is now several decades old, and age-related wear can lead to certain issues. Here are some common problems that owners and operators may encounter with this machine:
- Starting Problems
- Cause: Common causes of starting issues include a weak battery, fuel system problems, or issues with the starter motor.
- Troubleshooting: Check the battery voltage and ensure it’s holding a charge. Inspect the fuel system for clogged filters, air in the lines, or faulty injectors. Verify the starter motor and solenoid for wear or faults.
