16Y-11-00001 is the listed part number for this bulldozer pump pulley. The page does not identify the pump it drives or provide groove dimensions. Confirm the assembly position, pulley profile and mounting arrangement against the machine parts catalogue before ordering.
Check the installed drive
Record the machine model and serial, then locate the pulley in the relevant pump-drive illustration. Compare the hub, offset and belt or coupling interface with the installed part. If the pulley has been changed during prior service, the number on the current component may help, but supplier confirmation against the original application remains important. Do not assume a matching diameter is sufficient.
Inspect the mating components
During replacement, check the pump shaft, key or other drive feature and the belt alignment as applicable to the installed configuration. Look for wobble, damaged grooves or evidence of misalignment. Follow the service manual for removal and tightening; no dimensions or torque values are stated on this page. If the original pulley failed, diagnose the cause before returning the machine to work.
