Land Rover Transfer Box

As you probably know some Land Rover gearboxes always suffered from mainshaft/input gear spline wear. This is due to the fact that oil isnt able to get the the splines to keep them lubricated and reduce wear. On later models of the LT230 transfer box rover fitted cross drilled input gears. These gears simply had holes drilled into them allowing oil to reach the splines. Also, oil feed plates were fitted to get important lube to splines.

You can fit a cross drilled input gear to most LT230 transfer boxes, with a few exceptions. However, it is a lot easier and cheaper to fit an oil feed plate, which is compatible with all LT230’s. Be aware that the oil feed plate only works with the aluminium PTO cover plates, not the pressed steel ones, so you will need to swap that at the same time. Below is a quick guide to the job, and at [...]

Picking the right oil for your Land Rover gearbox is important for various reasons. Things like wear and tear, gear changes, and noise are but a few. Each gearbox was designed with a specific oil in mind, and if you choose to use a different oil in your gearbox it may not perform as it should.

For example, Land Rover gearboxes fitted with bronze bulk rings will want the right kind of oil to allow them to work correctly and be able to grip the gears. At the same time, the oil needs to be the right viscosity to be easy for the oil pump to shift and slippy enough to lubricate all the bearings. In extreme conditions the oil needs to be even [...]
