ProSteering ® Additional gear identification methods Frame mounting pads The gear housing is one of the easiest methods to use in the process of identifying a gear part number. The gear housing is generally what makes a gear unique or different from other gear part numbers. This method is easy and helpful; however, it is not 100% accurate as some gears have RH or LH internal components, different input shaft connection, relief valves, etc. Looking at the frame pads is a simple and helpful guide to identifying the gear part number. Typically, a steering gear will have 3 or 4 mounting pads on occasion there are 5. Looking at the number of frame pads, location of the frame pads, and thickness of the frame pads then comparing to the pictures included in Appendix I of this technical guide will help determine the gear part number. It is especially important to read the casting number on the gear housing for the TRW type steering gears when trying to identify a gear part number using this method.
