What is the input shaft and why does it fail?

The input shaft transmits engine torque from the clutch into the gearbox. Failure is typically caused by spline wear, bearing seat damage, or fracture from shock loading. A worn input shaft will cause vibration, noise in neutral and difficulty selecting gears.

What is the difference between the 23T and 25T variants?

This shaft is machined with a 23-tooth clutch spline on the input end and 25-tooth gear teeth — this is the standard MT-75 specification. Always verify against your gearbox part number before ordering.

What OEM number does this shaft replace?

This shaft replaces Ford OEM reference YC1R-7015-FD.

Should I replace the input shaft bearing at the same time?

Yes — it is best practice to replace the front input shaft bearing (and associated seals) whenever the input shaft is removed, to prevent repeat disassembly.

Which vehicles use the MT-75 gearbox?

The MT-75 is a 5-speed manual gearbox used in Ford Transit, Ford Escort, Ford Sierra, Ford Ranger, LDV Convoy and Mazda BT-50 applications.
