#25 Lima Class 47 Ringfield Motor Upgrade - Part A

Welcome back to my in-depth mini-series on upgrades to an old Lima Class 47 loco. This is the fourth video in the series and is Part A of replacing the ringfield/pancake motor with a brand new CD/DVD drive motor. In Part A, we look at dismantling the old motor, removing the gears for cleaning, adapting the plain bearing to accommodate a smaller drive shaft and positioning the new motor ready for gluing. Part B will then focus on fixing the motor into place, creating a small diode array to drop some volts so that the motor is less stressed by higher voltages and then wiring it all up to the DCC decoder. These are detailed, step-by-step videos. If you want a brief overview, you’ll find other options on YouTube and elsewhere. The methods used in this video are not necessarily the only way to do it, nor necessarily the best. --- 00:10 - Introduction 01:00 - Key components for the project 02:39 - Taking the loco apart 06:00 - Motor & grear disassembly 11:44 - Removing the bearing & making a brass bush 16:38 - Refitting the bearing 19:20 - Reassembling the gears & seating the new motor --- The 10mm CD/DVD drive motor should work in most Lima models locomotives of the following OO gauge classes: 08, 09, 31, 37, 40, 47, 52, 59, 60, 66 and 92. Other models may be able to accommodate a larger 12mm motor, but you must check dimensions yourself first. The replacement motor is a 12000rpm, 6V, 0.03A DC motor. The output from a DCC decoder or a DC controller can reach 12V DC (sometimes a little higher) at the top end. In order to avoid motor burn-out and prolong motor life: 1. Diodes should be used to reduce voltage (as shown in the video), 2. DCC decoders should have their CV5 value reduced (if available), and 3. Top speeds should be kept to a minimum and run at higher speeds for short periods only.
