Note: The RAVE contains exploded view diagrams of the two versions of transfer cases, with details.
From the RAVE workshop manual, transfer case:
General
The LT 230SE transfer box is mounted at the rear of the gearbox and transmits drive via high or low reduction ratios
to the front and rear axles via the propeller shafts. The high/low ratios are 1.211:1 and 3.32:1 respectively.
Transfer boxes fitted to this model have the prefixes 41D and 42D to the unit serial number. Prefix 41D denotes that
the unit is not fitted with interlock whilst 42D denotes that interlock is fitted.
Vehicles up to 03 model year –
Whilst similar to LT230Q transfer boxes fitted to other models, the LT230SE transfer
box has certain engineering modifications incorporated which are as follows:
l
Uprated torque capacity
l
Modified front and rear output and cross shaft housings
l
Intermediate gear bearing pre-load now controlled by a selective, non-collapsible spacer
l
Speedometer drive and driven gears not fitted for this application
l
Modified high/low sleeve
l
Modified front output flange and mud shield
l
Differential lock fitted to certain vehicles, but no longer driver operated
l
Fixed setting of differential lock warning lamp switch on vehicles fitted with differential lock
Vehicles from 03 model year –
The LT230SE transfer box is as described above for vehicles up to 03 model year
with the following modifications:
The following items are introduced on vehicles from 03 model year
l
Ribs added to main casing to reduce operating noise
l
Revised machining process for intermediate gears to reduce operating noise
