Installation
Installation is carried out in the reverse order of removal, taking into account the following.

Check that the propshaft flanges are free of grease. Remove the protective film from the gaskets and install the gaskets on the flanges with the sticky side to the cardan shaft.
Raise the main reverse gear so that you can attach rear drive shafts to the flanges of the main reverse gear. Screw in, but do not completely tighten the bolts securing the drive shafts to the flanges of the main reverse gear.
Raise the main reverse gear, put it in place and fix it with bolts 1 and 2 on the rear transverse beam (see fig. 11–8).
When installing the cardan shaft, to eliminate imbalance, align the marks on the flange of the cardan shaft with the marks on the flanges of the gearbox and final reverse gear (see fig. 11–3).
Screw in bolts of fastening of the cardan shaft to flanges of the main reverse gear.
