Introduction
This kit provides a second driven sprocket on the reel drive. With the optional 52-tooth driven sprocket, the operator can
switch from high torque to high speed for operating in light crops at increased ground speed.
This document explains how to install the kit. A list of parts included in the kit is provided in Chapter 2 Parts List, page 5.

Conventions
The following conventions are used in this document:
•Right and left are determined from the operator’s position. The front of the header is the side that faces the crop; the
back of the header is the side that connects to the combine.
•Unless otherwise noted, use the standard torque values provided in the FD2 operator’s manual and technical manual.

WARNING
Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury. It may also be
used to alert against unsafe practices.
CAUTION
Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury. It may be used
to alert against unsafe practices.

•Wear close-fitting clothing and cover long hair. NEVER wear
dangling items such as scarves or bracelets.
•Keep all shields in place. NEVER alter or remove safety
equipment. Make sure driveline guards can rotate
independently of shaft and can telescope freely.
•Use only service and repair parts made or approved by
equipment manufacturer. Substituted parts may not meet
strength, design, or safety requirements.

Figure 1.5: Safety around Equipment
•Keep hands, feet, clothing, and hair away from moving parts.
NEVER attempt to clear obstructions or objects from a
machine while the engine is running.
•Do NOT modify the machine. Unauthorized modifications
may impair machine function and/or safety. It may also
shorten the machine’s life.
•To avoid injury or death from unexpected startup of the
machine, ALWAYS stop the engine and remove the key from
the ignition before leaving the operator’s seat for any reason.

Figure 1.6: Safety around Equipment
•Keep service area clean and dry. Wet and/or oily floors are
slippery. Wet spots can be dangerous when working with
electrical equipment. Be sure all electrical outlets and tools
are properly grounded.
•Keep work area well lit.
•Keep machinery clean. Straw and chaff on a hot engine are
fire hazards. Do NOT allow oil or grease to accumulate on
service platforms, ladders, or controls. Clean machines before
storage.
•NEVER use gasoline, naphtha, or any volatile material for
cleaning purposes. These materials may be toxic and/or
flammable.
•When storing machinery, cover sharp or extending
components to prevent injury from accidental contact.

Figure 3.10: Reel Drive
IMPORTANT:
There should be approximately 38 mm (1 1/2 in.) of play on
one side (A) of the chain, while it is tight on the other
side (B). This level of tension and play in the chain is
required to skip one notch on the chain tightener.
4. Once the chain is tight, rotate the wrench upward to
properly engage the teeth from the lock/latch into the
tightener teeth. If the tightener will not skip a tooth before
tightening, do NOT force the tightener to the next notch.
IMPORTANT:
Do NOT overtighten the chain. If overtightened, the chain
will put excessive loads on the sprockets, causing motor
bearings and/or other components to fail prematurely.
