What is the MG5T gearbox?

The MG5T (also known as MA5T or BE4) is a 5-speed front-wheel-drive manual transaxle manufactured by PSA Group and used across Citroen, Peugeot, and associated platforms. It is a robust gearbox found in a wide range of compact and medium-sized vehicles.

What causes crown wheel and pinion wear?

Crown wheel and pinion wear is typically caused by operation with low or contaminated differential oil, impact damage from heavy use or kerbing, or natural wear in high-mileage units. Symptoms include whining or growling from the differential area, especially under load.

Does this set include both the crown wheel and the pinion?

Yes — this listing covers the matched crown wheel and pinion pair (Z:13–83). Crown wheel and pinion sets must always be replaced as a matched pair — never mix old and new components from this set.

How do I identify the correct ratio for my MG5T gearbox?

The crown wheel to pinion ratio is determined by the tooth count (Z:13–83 in this case). Different final drive ratios are used depending on the engine and vehicle variant. If unsure, send us your VIN and we can confirm the correct set.

Can the crown wheel and pinion be reused if only one shows wear?

No — always replace crown wheel and pinion as a matched lapped pair. Mixing a new component with a worn one will result in rapid wear and noisy operation due to the contact pattern mismatch.
