DESCRIPTION:

New Holland TC5070 Tractor Service Repair Manual (84270070)

• This SERVICE MANUAL was drawn up and produced by CNH Latin America Ltda. to meet the New Holland Dealer Network field personnel and mechanic training needs by updating – them with the latest technical information pertaining the New Holland TC5070 model Combine line and versions thereof in Brazil.
• All the information in this Manual are updated up to the date of publication. Any changes incorporated later on to the product will be disclosed either through Service Bulletins, which complement the information printed herein, or through periodic reviews of this same Manual.
• Follow the instructions listed below at the end of every season or when the machine has to remain stopped for a long period of time. This ensures the harvester is maintained in good general state and ready for the next season.
• Wash thoroughly the machine inside and outside removing all protection and inspection covers. After that, start it up and place it on a slope for a few minutes in order to remove all the water that may have remained inside it. After washing, uncouple the straw elevator with the header to check all locations that may have material built up. Ensure the machine is completely dry.
• Remove the grain, straw and tailings elevator chains smearing them with a mixture of lubricant oil and fuel; use the same mixture to smear the elevator boxes and reinstall the chains adjusting them to normal tension.
