SINGLE SCREW

RELEASE


SINGLE SCREW RELEASE OPERATOR INSTRUCTIONS

Sauer System utilizes a single-screw release in order to ensure that the full bore of a component's hub remains tangent with the shaft during operation. Mounting, clamping, re-positioning, and removal can all be achieved with minimal time and effort by a single operator using a single hand wrench. This effective design affords flawless operation when these instructions are adhered to.

Definitions: The release screw is marked with a nearby "open" sticker. The permanent holding screw is opposite of the release screw. This screw should only be loosened when completely removing the component from the shaft. The upper half is the piece of the component that features both counterbores for the release and permanent holding screws. The lower half is the piece of the component with the screw threadings.


1

Install the upper & lower halves on the shaft, joining the halves at the split-line key (See Photo A). Insert screws through counterbored upper half into the threaded lower half. Once halves are seated together loosely, tighten the permanent holding screw.

2

Move the component to the desired position on the shaft, and tighten the release screw, designated by an "OPEN" sticker (See Photo B). The single screw release system is designed to be easily engaged by any operator with one quarter-turn of a hand wrench (clockwise to clamp; counter-clockwise to release). A power tool is not recommended for this step as it may damage the release screw.

3

To remove component from the shaft, first loosen the release screw one quarter-turn as described in step two. Next, loosen the permanent holding screw, noting the specifications from step one. Remove the upper and lower halves from the shaft and re-assemble matching halves with both screws loosely threaded.

Single Screw Release Checklist: +800-444-8458 +800-444-1349

DO tighten the permanent holding screw first. This ensures that the release screw will clamp and un-clamp the part as intended.

DO store manual set parts (off the machine) with both screws tightened properly to prevent damage and mis-matching.

DO NOT overtighten the release screw. Overtightening may cause damage to the threading and wear out the part over time.

DO NOT use shims at the bore to secure the component in place. Shims may lead to inconsistent scoring definition due to an outof-round component.
