ADJUSTING TRACK TENSION
Crawler track systems use a grease cylinder to keep each track chain in tension. Screwed into the end of the grease cylinder is
grease fitting enabling grease to be pumped into the grease chamber and released from it, tightening and slackening the track.
• Take care when loosening the grease fitting as it is pressurised.
• If the tracks keep becoming slack, check for any leakage on the outer face of grease fitting.
• Check if there is any grease leakage at the contact surface between the grease tension and grease fitting. Ensure the tension
seals are not damaged.
• Before replacing seals, place a straight edge along the cylinder barrel as shown above to ensure outer sleeve has not swollen
from being overlooked.
• To replace seals, simply unscrew grease fitting push or pull out the inner cylinder to expose the lip seal and inner seal.
• At the side of the track frame there is an access cover, unscrew this to gain entry.
• Check that the grease fitting and grease gun adaptor is clean.
• Connect a grease gun to the grease fitting and add grease until the track tension is normal.
• Drive the screener forward and backward to check if the track is tightened
• At the side of the track frame there is an access cover, unscrew this to gain entry.
• Loosen the track fitting, by turning it in an anti-clockwise direction, using small movements until the grease is released. Once
you have achieved the correct tension, tighten the grease fitting by turning in a clockwise direction.
• Clean all excess grease.
• Remember to track the machine for a while forward and backward in order to assess if the tracks are at the right tension. This
movement will help the grease work through the tracks.
• It is important to be aware of the conditions that the sceener tracks are working in.
• Certain surfaces and environmental surroundings could cause corrosion. Tracks can also seize if they are not moved on a daily
basis. To prevent this, track the machine a few meters in both directions.
