General repair instructions

The maximum possible care, cleanliness and

proper tools are essential to ensure satisfactory
and successful transmission repairs. The usual
basic safety precautions also apply when
performing vehicle repairs.

A number of generally valid instructions

applicable for the various repair procedures -
which were previously repeated a number of
times at numerous places in the Repair Manual -
are summarized here. They apply to this Repair

Transmission

When installing ensure that the dowel sleeves

between the engine and the transmission are
correctly located.

When assembling mounting brackets as well as

other waxed components the contacts surfaces
must be cleaned. Contact surfaces must be free
of grease and wax.

When changing a transmission fill it with gear

oil to the lower edge of the filler hole.
