Special tools
For a complete list of special tools used in this workshop manual,
see ⇒ "Workshop equipment and special tools" .
Gearbox
♦ Do not run engine or tow vehicle with sump removed or when
there is no gearbox oil in the gearbox.
♦ Thoroughly clean all joints and surrounding areas before dis‐
mantling.
♦ When installing, ensure that the dowel sleeves are fitted cor‐
rectly.
O-rings, seals, gaskets
♦ Always renew O-rings, seals and gaskets.
♦ Oil seals are also called radial oil seals.
♦ After removing gaskets and seals, always inspect contact sur‐
face of housing or shaft for burrs resulting from removal or for
other signs of damage.
♦ Thoroughly clean housing joint surfaces before assembly.
♦ Lightly lubricate outer circumference and sealing lip of oil seals
with gearbox oil before installing.
♦ Coat O-rings with oil to prevent pinching of rings during as‐
sembly.
♦ Never use any other types of lubrication in the gearbox oil
section. Otherwise there is a risk of malfunctions in the hy‐
draulic gearbox control.
♦ The open side of the oil seal faces the side with fluid filling.
♦ Press in new oil seals so that sealing lip does not contact the
shaft in the same place as the old seal (make use of insertion
depth tolerances).
♦ Observe rules for cleanliness
