EXTRAORDINARY JOBS
DISASSEMBLY
Before carrying out any maintenance work the outside of the transmission must be cleaned with a jet of
steam. Seal all openings before doing this so that water and dirt cannot get inside and damage the
fundamental parts.
To disassemble the axle parts the axle itself has to be taken off the vehicle first. This also entails
removing the wheels and the hydraulic pipes from the braking circuit as well as draining the oil from the
differential and hubs, removing the plugs.
When disassembly is finished, carefully remove the dirt from each single piece, throwing away all those
parts that (due to their nature) when assembling, have to be replaced with others in perfect condition:
gaskets, seals, worn bearings, screws with worn thread
ASSEMBLY
More than 90% of the bearings break due to dirt which is always abrasive. Dirt can get inside the
transmission during assembly or be transported by the lubricant during operation. Dirt can also get inside
by way of the seals, outlet plugs or even by means of the containers for filling up and changing the oil.
Prior to assembly each piece must be cleaned thoroughly and those parts that require it oiled. The
components that need oiling must be lubricated with new oil before being assembled.
NOTE: When reassembling it is essential to replace all the seals. Take care NOT to pinch the oil retainers
during assembly.
