Track tension (Initial)
WARNING
Pressurized fluid can penetrate the skin and cause severe injuries.
The grease in the track tensioning mechanism is under high pressure. Keep face and body away from
grease nipple. Never loosen the grease nipple more than one complete turn.
Failure to comply could result in death or serious injury.
W0959A
Clean the tracks and undercarriage as required or at the end of the work shift. Park the machine on a level surface
to prevent distortion of the track seals. If the temperature is cold, park the machine on a surface that will not freeze
to the track shoes.
Check the track tension at 100 hours when the machine is new during the initial run-in period or if the track has been
replaced. Check the track tension frequently when you operate. Check the track tension more often when working in
extreme conditions. When material packs and collects on the undercarriage parts the tracks may become too tight.
Correct track adjustment will help control undercarriage wear. Maintain correct track tension.
Prior operation:
Keep all unauthorized personnel clear of the area. Park the machine on level ground, in neutral with the parking
brake applied, and the attachment lowered to the ground. Make sure that all residual pressure is relieved from circuits
before beginning maintenance.
Track tension check
1. Move the machine backward the length of the track,
and then forward the length of the track. This will make
the bottom of the track tight. Bring the machine slowly
to a stop. Do not use the brakes to stop the machine.
2. Stop the machine so that a pin
(1)
in the track chain is
over the front carrier roller
(2)
— the roller nearest the
front idler. Park the machine on level ground, in neu-
tral with the parking brake applied, and the attachment
lowered to the ground. Turn off the engine, and remove
the key.
3. Stand on the tracks between the front and rear carrier
rollers, and then between the front idler and the front
carrier roller.

4. Place a straightedge over the track, and measure the
track deflection (sag) midway between the front carrier
roller and the idler wheel. Then place a straight edge
over the track, and measure the track deflection (sag)
midway between the two carrier rollers. Average the
two measurements and adjust the track to average be-
tween
44.50 - 58.00 mm
(
1.75 - 2.25 in
).
