D7G tractors … PM link for linkage

PS: The Preventive Maintenance Monthly, Jan, 2005

Operators, here are some quick pointers that will link you up to the right PM on the dozer's throttle linkage.

A Stuck Lever

Moisture and mud corrode the linkage for the governor control lever (throttle). Enough corrosion causes the lever to push or pull sluggishly, erratically or not at all. A stuck lever isn't much good when you need to increase or decrease engine speed during construction operations.

Wipe off the dozer's throttle with a brush or clean rag. Then spray a shot of lubricating spray, NSN 9150-00-458-0075. Work the throttle lever back and forth a few times.

Make sure to spray the linkage at every scheduled service. Lube puts the slide and glide back into the linkage for smooth operation.

No Step Here

The throttle linkage looks like a convenient footrest while working on the engine.

Problem is, all that weight will bend the linkage and its swivel arms. The end result is erratic movement--not good! If you see wear marks on the linkage, it's the tell-tale sign that someone's hoot v, as there.

So keep your boot off the linkage when cleaning or doing maintenance or a PMCS check.
