Hornby R072 OO Gauge BR Class 25 CDrom Motor Upgrade, Pickups and Cabs

[calvin Streeting]

Ok
So i had a pair of old Hornby class 25 (well more like 1.75 class 25's). bothe with burntout ringfield motors

and wanted to see if i could save one and upgrade one to dcc an improve its runnings by:

1. changing the motor
2. removeing traction tyres
3. adding more pickups (all wheels)
4. add lights
5. add cab details (as had none).

 

Motor 1:
I sourced some replacement cd rom motors and rather than using a 6v replacement i found a 12v version on aliexpress

MABUCHI RF-300FA-11410 D/V 13.0 DC 
https://www.aliexpress.com

 

and designed a bracket to fix it in place

 

 

Wheels 2:
As i had 2 (ish) i noticed that I could scavange the unpowed boggie wheels from both locos and combine into 1 set of non traction tyre versions. i know i loose some traction ut will add a bit more wieght to help that.

 

pickups 3:
Designed a bracket for the unpowerd boggie that i could put in bronze wires to top of wheel (would Have gone with side pickups, but the boggie has a metal frame and i wanted to avoid shorts. this method was also added to the motor mount (and a small piece for the gear side, to be glued in pace)

As a by product I had to remove the nub on unpowed bogie end, but that helped solve the lean. and i now have 8 wheel pickup

 

 

Lights 4:
Got some by colour (red/yellow, with common anaode) led's for headlights and yellow for cab and headcode light (which i cut a hole in the window glass so headcode and cab can be one light and folowing this guide https://loco-updates.uk/class-153-2/index.htm and added directional led's to front (one red/yellow and other side just yellow wiried up.

 

 

Cabs 5:
Ok i had none in the 2 (ish) loco's so out can cad and a few mins latter i had a set. (notice the motor end version is shorter due to gears, but i can live with that as some is better than none.

 

 

Done:

on the layout :) and alot better.

Next:

next need to sort some headcodes and some weathering to grim the to 1960's grime. and sort some headcodes, and onto a tender driven 8F that i wont to convert to loco powered.
