ROT A TING SHAFT SEALS
For correct rotating shaft seal proceed follows:
• before assembly , allow the seal soak the oil will sealing for least thirty
• thoroughly clean the shaft and check that the working surface the shaft not
• position the sealing lip facing the fluid; with hydrodynamic take into consideration the shaft rotation direction and position the grooves that they will deviate the fluid towards the inner side the seal.
• coat the sealing lip with a thin layer lubricant (use oil rather than grease) and fill the gap between the sealing lip and the dust lip double lip seals with grease.
• insert the seal its seat and press down using a flat punch seal installation not tap the seal with a hammer
• whilst inserting the check that perpendicular the seat; once make sure that makes contact with the thrust
• prevent damaging the seal lip the position a protective guard during installation
O - RING SEALS
Lubricate the O - RING seals before inserting them the seats, this will prevent them from overturning and which would jeopardise sealing ficiency
SEALING COMPOUNDS
Apply one the following sealing compounds the mating surfaces when specified: SILMA TE® R L OCTITE ® RTV 598 L OCTITE ® I NSTANT G ASKET 587 B LUE . Before applying the sealing compound, prepare the surfaces directed product container follows:
• remove any incrustations using a metal
• thoroughly - grease the surfaces using a locally approved cleaning agent such safety solvent brake parts cleaner
ARE P ARTS
Only use "CNH Original " CNH Parts".
Only genuine spare parts guarantee the same quality , duration and safety original they are the same parts that are assembled during standard Only "CNH Original " CNH can fer this guarantee.
When ordering spare always provide the following information:
• machine model (commercial name) and serial number
• part number the ordered which can found the the Parts Catalogue", used for order processing

PROTECTING THE ELECTRONIC / ELECTRICAL SYSTEMS DURING CHARGING
T o avoid damage the electronic / electrical always observe the following:
Never make break any the charging circuit including the battery when the engine
Never short any the charging components ground.
Always disconnect the ground cable from the battery before arc welding the combine any header tached the
• position the welder ground clamp close the welding area possible
• welding close proximity a computer then the module should removed from the combine
• never allow welding cables lay near across any electrical wiring electronic component while welding progress
Always disconnect the negative cable from the battery when charging the battery the combine with a battery charger
NOTICE: welding must performed the either the combine the header (if the battery ground cable must disconnected from the combine battery . The electronic monitoring system and charging system will damaged this not
Remove the battery ground cable. Reconnect the cable when welding completed.
W ARNING
Battery acid causes severe Batteries contain sulfuric A void contact with eyes
Antidote - EXTERNAL: flush with water . INTERNAL: drink large quantities water milk. Follow with milk beaten egg vegetables Call physician immediately EYES: flush with water for minutes and get prompt medical attention.
