JCB Gearbox Test Rig
Home > Projects
Project overview
JCB Transmissions, a long-standing partner of Incotech, required a new end-of-line test rig for a newly developed gearbox.
The challenge was to create a fully loaded, high-torque gearbox testing machine capable of simulating real-world operating conditions while capturing comprehensive performance data — all while integrating with the Transmission Control Unit (TCU) for automated operation and monitoring.
the solution
Incotech delivered a fully engineered gearbox test stand tailored to the new product line:
-
Full Load Simulation – Input motor sized comparable to a JCB Loadall engine and two output motors simulating front and rear axles, capable of stalling the gearbox under high torque.
-
Energy Recovery – Power from the output motors is fed back into the system, improving efficiency during testing.
-
Automatic Coupling – Input and output flanges/yokes connect automatically within the test rig for consistent setup.
-
Integrated Control & Data Acquisition – VMC control system communicates with the TCU via CANBUS, capturing pressures, speeds, vibration, torque, and temperature.
-
Oil Management – Gearbox oil is continuously cleaned during testing to remove break-in debris, with oil cleanliness measured and recorded.
-
Full Project Management – Incotech managed the project from design to commissioning, delivering on time and within budget.

DARREN FLETT: SYSTEMS LEAD, DRIVE TRAIN
‘I just wanted to send you a message to thank all at Incotech for their support and dedication to the leak test fixture that you have delivered against our very difficult timing plans. The customer was very pleased with the fixture that you produced and we had good feedback on our process. Once again thank you all at Incotech for their hard work on this.’
MARC PIDGEON - COMMODITY BUYER
‘I want to personally thank you all for your efforts and the work that has been completed both on the test stand design, implementing the great changes to the current rig design process, the validation of the test stand, both within India, and the UK. As well as the smooth transport and installation in India.’
‘I just wanted to thank you very much for the excellent response to our ‘plea for help’. Your swift response to repair our Middlemarch Dyno, meant we were able to carry out some extra testing for our crucial customer deadline on a Friday evening. This made a huge difference to the data we submitted and I am very grateful for your support to achieve this.’
