All units received into the workshop are cleaned before being stripped. One of our skilled engineers will then carefully dismantle and inspect your unit free of charge.
Our inspection is followed up with comprehensive findings report and competitive no obligation quote for any required work.
As part of the repair process, all damaged and worn parts will be replaced, along with all bearings and seals. Mating faces will be reworked, and the unit will be thoroughly cleaned before being rebuilt back to OEM specifications. As standard, any unit received with fittings will be returned to customers cleaned and all O-rings will be replaced.
The unit will then be tested on our custom-built test rig. Our test rig has been designed specifically for purpose and has the flexibility to test the majority of products available.
Whilst JCB manufacturer their own hydraulic units, you will also find the following Manufacturers are used:
There are some key signs that your JCB hydraulic pump or motor is in need of a repair. This can be anything from loud whining or knocking noises during use, visible oil leaks or excessive heat in the system. Then there are performance issues like failing to lift certain loads, jerky movements or slow or sluggish operations. Worn-down internal components, broken seals and more could also cause these issues.
There are five most common causes of JCB hydraulic pump failure:
Oil contamination – This can occur because of dirty/contaminated oil making its way through the system or old oil that has oxidised and thickened up, thus starving the pump and causing a blockage
Hydraulic overheating – Overheating will happen either from internal friction that has caused wear and tear on seals, from blocked cooling systems or from broken down components, causing the rest of the pump to work harder
Mechanical/human error – Whether through using the wrong parts, refilling with the wrong oil or when a pump suffers a sudden shock load
Cavitation – This can also be seen as flooding the system. When a pump pulls in more fluid than it can handle, it will cause vacuum bubbles that implode, causing misfires and damage in the system
Aeration – If air gets into the pump system, you will start to hear loud knocking or squealing. This will typically happen when oil levels are low, suction clamps are loose or you have damaged inlet hoses
Once your equipment has been repaired and rebuilt, it is important to thoroughly test said equipment to ensure that it is working back to optimum levels. For a hydraulic pump or motor, the primary way of doing this would be to conduct volumetric tests, pressure tests and flow monitoring. This will all be done on our purpose-built rig system for complete verification.
On all repairs conducted by the experts at CJ Plant, we provide a full, free strip and inspection with detailed diagnostics. We will then work out a quote for full repairs, which are then protected by a comprehensive 12-month warranty.
Final drive repair is our speciality, and we also offer repairs for hydraulic motor and pump units. We work fast to minimise your downtime and return your parts in good condition
