Frequently asked questions

What is the gearbox mainshaft spring pin used for?
The gearbox mainshaft spring pin locates and retains a component on the mainshaft of the R380 five-speed manual gearbox, at the 5th/reverse position. It's a sprung-steel pin driven through aligned bores, holding the part against axial movement on the shaft without a separate fastener.
Which gearbox and models does this spring pin fit?
This spring pin fits the R380 five-speed manual gearbox used in the Defender, Discovery 1, Range Rover Classic and Range Rover P38. On the Defender it applies to gearboxes from serial number (G)410128J onward, so check your gearbox serial if your vehicle is borderline.
Should the mainshaft spring pin be replaced during a gearbox rebuild?
Typically this spring pin is renewed whenever the R380 mainshaft is dismantled, since driving the old pin out usually relaxes its spring tension. It's an internal gearbox part, so it's normally only accessed during a full gearbox strip or 5th/reverse repair on these Land Rover models.
