DESCRIPTION:

New Holland Boomer 8N Compact Tractor Service Manual (84307374)

• This service manual provides the technical informa- tion needed to properly service the New Holland Boomer 8N CVT transmission.
• Use this manual in conjunction with the operators manual for complete operation, adjustment, and maintenance informa- tion. On New Holland equipment, left and right are determined by standing behind the unit, looking in the direction of travel.
• GENERAL
• The Boomer 8N tractor has been built using metric hardware.
• NOTICE: Be sure to use the hardware specified when using tapped holes, as trying to install a metric bolt in an inch thread, or an inch bolt in a metric thread, will damage the thread. Certain hardware must be tightened to specific torque specifications.
• If specific torque specifications are not noted, tighten the hardware to the standard torque chart specification listed in this manual.
• Hardware used on New Holland tractors is plated with zinc chromate (gold color). Gold colored hardware has different torquing requirements from unplated or zinc plated (silver color) hardware because of the difference in the coefficient of friction of the plating material.
• The torque charts in this manual list the correct specifications for gold, silver, and unplated bolts.
• Whenever possible, the nut should be tightened, not the head of the bolt. When tightening using the bolt head, the clamp load can be lost because some of the torque applied twists the bolt instead of tensioning (stretching) it. The tension on the bolt is what holds the joint together.
