the intermediate gears the centre differential assembly The front and rear output housings are bolted to either side of the main casing. Mainshaft Input Gear The transmission output shaft is splined into the mainshaft input gear, which is supported by taper roller bearings. Input gear bearing pre-load is achieved by the use of a selective shim located in the bearing housing. Intermediate Gears The intermediate gear cluster is supported by the taper roller bearings located at each end of the cluster and runs on the intermediate shaft, which in turn, is supported at the front and rear by the main casing. Intermediate gear bearing pre-load is achieved by means of a collapsible spacer positioned between the bearings, the amount of compression applied to the spacer is by means of a nut on the end of the intermediate shaft. The bore of the intermediate gear is machined with a shoulder at each end to locate the bearings.
