Defender Stumpy R380
The stumpy R380 is a shortened version of the 300tdi R380. Its a direct replacement for an LT77. It will not fit TD5 or V8 engines.
All the gearboxes built at Syncro Gearboxes are completely stripped to a bare gearbox casing so that each and every part can be inspected. Every ‘consumable’ part is discarded and the core parts are retained.
After which the casing along with all relevant parts is dipped into our decarbonising fluid bath to burn off all traces of oil, grease and paint. A choice of specification is decided with the customer and then the gearbox is assembled with all tolerances and torque settings checked and set along the way.
The original helical gears are checked and replaced if required. The gearboxes synchromesh hubs are stripped and fitted with new springs, the gear selector forks are checked for wear or damage and replaced if necessary. Any parts that are found to be damaged or warn are replaced and the rebuild continues.
High Ratio 5th Gear
If you are running a non V8 R380 you have the option to upgrade your 5th gear to a higher ratio variant. The higher ratio will give better cruising and reduce revs when you are on the motorway. The higher ratio 5th gear is normally fitted to the v8 R380 offering a 0.73:1 ratio rather than the lower 0.77:1 as fitted to the diesels. A nice upgrade if you are doing a lot of motorway mileage.
