How do you adjust excavator track tension with the proper tool?

Question

VANROCK Track Solutions · Accepted Answer

On most excavators, track tension is adjusted at the grease cylinder behind the idler, and the “tool” is usually a grease gun plus the correct fitting for the tensioner valve. The track should be set to the machine manual’s specification; if it is too tight, wear and rolling resistance increase, and if it is too loose, the track can de-track or jump the sprocket.

Before adjusting, clean packed mud and stones from the undercarriage so you are measuring the true sag. Then check the grease fitting, side access point, or relief valve used on that machine. Add grease slowly to tighten the track, or release grease carefully to loosen it. Never stand directly in line with the track, idler, or tension cylinder while working.

A good adjustment also depends on the conditions. Soft, sticky soil can pack into the track frame and temporarily make the track feel tighter, while wear in rollers, idlers, sprockets, or the chain can make a correct setting difficult to hold. If the track keeps coming loose, the tensioner, seals, or undercarriage wear may need inspection.
