16Y-40-09000 is the listed part number for this bulldozer track roller. A roller works within the undercarriage, so the buyer should confirm the machine model and serial as well as the roller position and track-frame configuration. This listing does not provide dimensions or a model range.

Inspect the undercarriage before ordering

Record where the roller is installed and compare that position with the machine’s parts diagram. Check the existing roller’s mounting points, shaft and flange arrangement, but use the catalogue reference for final identification. Track-frame wear, damaged brackets or abnormal track alignment can affect service life; inspect those conditions rather than assuming the roller alone explains the wear pattern.

Fitment and maintenance considerations

Ask the supplier to confirm 16Y-40-09000 against the machine serial and undercarriage revision. During replacement, follow the service manual for lifting, machine support, fasteners and safety controls. Keep dirt away from the bearing and sealing areas, and complete the manufacturer’s post-installation checks. Do not apply a generic torque value or interchange recommendation from a different machine.

For other bulldozer parts in this group, consult the 16Y-15-00009 shaft-coupling listing only if that separate component is also part of your repair; it is unrelated to roller fitment.
