   A - Chain Pin

   B - Carrier Roller

   C - Distance

   D - Fitting Base

   E - Fitting

   The track adjustment procedure should be performed under the same conditions in which the machine is used. Dirt buildup must not be removed from the track, if buildup conditions exist on the job.

   Move the harvester forward a distance of twice its length. Allow the harvester to come to a complete stop when one of the chain pins (A) is centered on the carrier roller (B).

2. Measure the distance (C) between the track chain and track frame.

   Item	Measurement	Specification
   Track Chain to Track Frame	Distance	32—38 mm (1.25—1.5 in.)

3. If track tension adjustment is necessary:

   • If measurement is more than specification, the chain is too tight. Loosen base of grease fitting (D) until grease escapes. Tighten fitting.
   • If measurement is less than specification, the chain is too loose. Add grease to fitting (E) until the proper measurement is reached.
