He recommended 2 specific Bosch part numbers 0 332 002 150 for the 60A inductive SPST hydraulic pump relays 0 332 204 150 for the 15A inductive flap relays the number on the 15A unit has been changed to 0 332 209 150. The contact information which he provided is outdated, so I thought I'd provide the updates for those of you who might be looking to substitute these items for the Lancair supplied parts. If you don't remember why he suggested the change, this is what he told me: >>> I used the Bosch relays to control the hydraulic power pack because: 1. They were smaller and lighter, and 2. They were more reliable. (They were specifically designed to handle inductive loads, and are life-cycle rated.) <<< The manufacturer can be contacted at Robert Bosch Corp Automotive Group 2800 S. 25th Ave Broadview, IL 60153 708-865-5200 The number that he gave for Twentieth Century Marketing is no longer in service, (it was where he obtained data sheets from), but I do have a good number for a distributor in PA who will sell these things directly. They are readily available from Brandon Products 800-422-3274. The 60A units are US$13.27 each, and the 15A ones are $2.57.
