138-6674 Bucket Control Pin for CAT 966 and CAT 972 Wheel Loaders

138-6674 Bucket Control Pin for CAT 966 and CAT 972 Wheel Loaders

The 138-6674 Bucket Control Pin is a replacement pin used in the bucket control and linkage system of CAT wheel loaders.

The pin works with related bushings and linkage components and is exposed to repeated movement and load during loading operations. As the pin wears, clearance can increase between the pin and bushing, which may lead to loose movement, noise and faster wear of the surrounding parts.

GT supplies 138-6674 replacement bucket control pins for CAT 966 and 972 series wheel loaders, including 966G, 966H, 966K, 966K XE, 966G II, 972G, 972G II, 972H and 972K.

138-6674 Bucket Control Pin Application

The bucket control pin is part of the mechanical connection within the loader's bucket control and linkage system.

During normal operation, the pin is repeatedly loaded as the bucket moves through digging, lifting, carrying and dumping cycles.

A worn pin can affect the fit between the connected components.

Common signs include:

Excessive clearance around the pin
Loose bucket linkage movement
Knocking or abnormal noise
Visible wear or scoring on the pin
Faster bushing wear
Uneven movement of the bucket linkage

If excessive play is found, inspect the pin, bushing and bore together before deciding which components need replacement.

What is 138-6674?

138-6674 is a Bucket Control Pin used in CAT wheel loader applications.

Which CAT machines use 138-6674?

The part is listed for CAT 966G, 966G II, 966H, 966K, 966K XE, 972G, 972G II, 972H and 972K wheel loaders.

Is 138-6674 a bucket pin?

It is specifically identified as a Bucket Control Pin, used within the bucket control/linkage system rather than simply being described as a general bucket pin.

Does the pin work with a bushing?

Yes. The pin works together with a corresponding bushing in the applicable linkage assembly. Both parts should be inspected when excessive clearance develops.
