2.1 General instructions
Important caution
All repair and maintenance works described in this manual must be carried out only by the AGCO Service
Network, strictly complying with the instructions given and using, whenever required, the special tools.
Anybody who carries out the above operations without scrupulously complying with the instructions shall
be held personally liable for any damage caused as a result of their actions.
Adjustment shims
During any adjustment, select the adjustment shims by measuring them individually with a micrometer and
then adding up the values obtained: Do not rely on the incorrect measurement of the total shim pack or on
the nominal value given for each ring.
Rotary shaft seals
For correct rotating shaft seal installation, proceed as follows:
• before fitting the seals, soak them for at least half an hour in the same oil they will be sealing;
• thoroughly clean the shaft and make sure that the shaft working surface is not damaged;
• move the the sealing lip towards the fluid; in the case of a hydrodynamic sealing lip the grooves must
face in such a way that, considering the shaft rotation direction, the fluid is taken back towards the inner
part of the seal;
• smear a thin layer of lubricant on the sealing lip (oil rather than grease) and fill the gap between the
sealing lip and the dust lip with grease on twin lip seals;
• fit the seal in the relevant housing by pressing it or using a drift with a flat contact surface; do not beat it
with a hammer or a mallet;
• during driving, make sure the seal is perpendicular to its housing and, when driving is finished, make
sure it touches the shoulder;
• to prevent the sealing lip from getting damaged by the shaft, lay down suitable protection when fitting
both parts
O-rings
Lubricate O-rings before fitting them in their seats to prevent them from rolling over and twisting during
fitting, thus jeopardizing their sealing action.
Sealants
Before laying the sealant on the mating surfaces, prepare them as follows:
• remove any scales with a wire brush;
• thoroughly degrease the surfaces with one of the following cleaning agents: trichloroethylene, oil or a
solution of water and soda.
Spring pins
While fitting split spring pins, make sure that their groove is directed towards the effort direction, stressing
the pin. Spiral spring pins do not need any orientation during fitting.
Notes on spare parts
Only use genuine AGCO parts.
Only genuine parts guarantee the same quality, life and safety as original parts because they are the same
as those fitted as standard.
Only genuine AGCO parts can offer this guarantee. All spare parts orders must be accompanied by the
following data:
