Product Information

We can supply both the earlier (26th tooth) and later cross-drilled (26th and 28th tooth) input gears.

To identify which type you need you will need to look at the your transfer case serial number. The last letter of this will denote whether your vehicle is able to accept the later cross-drilled type. A transfer box with the suffix A or B will only accept the earlier 26th tooth, non cross-drilled type (FRC5428). A transfer box with the suffix C onwards will accept the later cross-drilled type. See below to find the serial number :

This gear is the first gear in the LT230 transfer box and the LT77/R380 output shaft engages into it. As it is prone to wear we recommend that this part is inspected when changing either the LT77 or R380 gearbox. The later cross-drilled type was modified from the earlier type to aid oil lubrication of the gearbox. If you have a 200 tdi Discovery or Defender, or any R380 your vehicle can accept the later cross drilled type. For other vehicles, in order to identify the correct gear, we will need to know the serial number from you transfer box to identify the correct gear (see transfer box section to identify this number). The earlier transfer boxes suffixed A & B are unable to accommodate the cross drilled input gear and we would only be able to supply the earlier type, FRC 5428.  If you do need an FRC5428 then you can add additional lubriction by fitting a oil feed plate

If you are fitting a cross drilled gear to a LT230 which is fitted to an 4 speed automatic you will need to check the length of the spline on the automatic gearbox output shaft, note the cross drilled needs a longer spline on the
