This page is the first site listing for a guide pulley with part number 16Y-11-00012. The original “(1)” suffix is retained as a record label, not presented as an engineering variant. Confirm the pulley’s catalogue position and the machine serial before ordering.

Verify where the pulley is installed

The product record does not name the assembly or provide dimensions. Check the machine parts diagram for 16Y-11-00012 and compare the mounting arrangement with the installed part. If the item has been removed, record its markings and position before cleaning. Ask the supplier to confirm whether the listing is for a single pulley or a larger assembly.

Resolve the duplicate reference

A second site record also uses 16Y-11-00012 and includes “(2)” in its original title. No evidence here shows a difference between the two items. Ask the supplier whether the records refer to duplicate entries or distinct supply configurations. Do not select one over the other based on the suffix alone.

See the second 16Y-11-00012 guide-pulley record for comparison; both need the same catalogue confirmation.
