Zeiss LWZ.3 Motor Bracket Install Guide

Overview

This kit includes a Motor Mount (2 screws), Heden M26T Eccentric, and Zoom Gear Extension (8 screws). Installation is simple and only requires a single phillips head screw driver.

Installation

Remove the rear cap to allow the zoom gear to slip over the lens body. You can handle that, right?

Gently lower the zoom gear over the original iris and zoom gear, into position on the zoom ring . Keeping it perfectly straight is critical. If the Zoom Gear isn't straight, it'll get jammed. 

Insert and tighten all eight screws provided with the Zoom Gear. 

Align Motor Mount at the top of the lens, between the two "ZEISS" badges. Insert and tighten two screws provided with the Motor Mount. 

Install and align Heden Motor with new Zoom Gear Extension ring. Adjust eccentric ring to snug Heden Motor gear up to the new Zoom Gear. Be careful not to position the Heden Motor too close as this may cause excessive pressure on the Motor Mount and misalignment.
