Buckets and Ground Engaging Tools
(GET). The 990H offers a variety
of bucket types and available GET
configurations to properly configure
the machine based on material density,
impact and abrasion.
Depending on your material densities,
there is a 8.4 m
3 (11 yd 3 ) Spade Nose
bucket with teeth and bolt-on segments
for improved performance and edge
protection available.
Increased full turn static tip load,
horsepower and hydraulic capabilities
allow the 990H to effectively utilize the
8.6 m
3 (11.25 yd 3 ) and 9.2 m 3 (12 yd 3 )
bucket size in lighter materials such as
limestone. All buckets feature the well
proven shell-tine construction.
To better match your 990H to material
conditions, contact your Caterpillar
dealer for specialty bucket needs.
K-Series GET. Features reliable tip
retention as the retainer locks securely
to stabilize and tighten. Opposing inclined
side rails on the adapter stabilize the tip,
improve back loading resistance and
reduce strain on the retainer. A tight
fit between the tip and adapter limits
movement and reduces wear. The adapter
nose is stronger with no hole for the pin.

Bucket Selection Guide and Matrix
Changes in bucket weight, including field installed wear iron, can impact rated payload. Consult your Caterpillar dealer for
assistance in selecting and configuring the proper bucket for the application. The Caterpillar Large Wheel Loader Payload Policy
is a guideline intended to maximize wheel loader structural and component life.
