Oxford Rail Class 415 Adams Radial : Repair Request (Part 1)
HTML-код
- Опубликовано: 13 окт 2022
- I got sent this Oxford Rail Class 415 Adams Radial locomotive from Anthony as it was a non runner although the motor seemed to spin with power applied directly.
This repair took longer than expected so I have split it into two videos. Part 2 will follow soon.

Just started watching your channel.. and the sponge! Wow! Just great idea!!
Just purchased a beautiful but exactly as problematic Adams Radial with factory weathering from ebay. Unfortunately not only was the DCC socket/blanking plate burnt out, but the motor also seems to be one of the defective ones. It cant remain at a consistent speed at the same voltage, gets slower and worryingly hot at the same time. Going to replace the motor in it when I get the chance. But glad to see your repair videos as guidance!
Very interesting, I have watched both parts of you fixing this. I recently purchased the same locomotive in KER green. It had serious traction problems. At one point of my track the loco was standing still with the driven wheels slipping. Had never seen that happen before. There is a spring under the front bogie. It was too long, so it lifted the front of the loco up, lessening weight on the driven wheels. I shortened the spring to 1/3 of the original. Front bogie problem solved. However, the rear pony wheels were riding too low also, lifting weight off the driven wheels. I removed the rear pony axle and the extremely tiny springs under it. I then filed the U-groove for the axle about 0,5 mm deeper and reassembled everything. Now the loco is able to "seesaw" a little on the two driven wheels when pressing the front or rear of the loco downwards, so most of the weight is resting on the wheels it should. All in all well worth the effort, the loco runs beautifully. I do not recommend it for people who do not like to tinker with their locomotives, however.
I love how you just fix everything❤ Regards Elizabeth
Hi Bill
A bit of information on the socket. Socket pin 1 should be connected to the motor + and pin 5 to the motor -. The right rail pickups should go to pin 8 and left rail to pin 4. The blank plugs just bridge pins 8 to 1 and 4 to 5 (and sometimes pins 2 and 6 are connected through diodes for directional lights in DC) so the loco should never work without anything in the socket. There should never be a direct connection from rail to motor if a socket is installed.
Oxford themselves have admitted that there have been some bad motors that do just as you have discovered, I'd say the motor has gone bad and is drawing way too much current and is probably why the small device on the sockets board has burnt out.
You should get yourself some pinouts for the DCC sockets so you can understand how things should be connected for DC function.
Cheers Rob.
Great Trouble shooting on this model.
Very informative video.
I've said before - if you worked for the Model Makers (Oxford, Hornby etc.) they'd be manufacturing world beating models!!!
If there was a wire directly from the pickups to the motor then its been rewired at some point, and incorrectly, because for DCC the motor is completely isolated from the rails. You should have orange and grey from the pick ups to the DCC socket. And red and black from the motor to the socket. Then the blanking plate just connects red to orange and black to grey.
Another good one Bill. Looking forward to part 2!! All the best Rob
Nice bit of detective work on a number of faults. I do think DCC is witchcraft too! Seeing how far the front bogie swings out, I can't help thinking these newer locos aren't designed for minimum/tight radius points and curves.
That's a very nice looking locomotive, looking forward to seeing the next video
Lovely engine and running so quietly. Well done Bill
a very elegant locomotive👍
I had a 33 class with dcc fitted and as I only will be running dc so i ripped out the dcc board and hooked all the wires up and rund like a brand new bought 1....
Cheers from John in Australia.
I have gone through comments. Oxford did provide replacement bogies. Always a troublesome model. Hornby made a better one
A two parter.... so far so good.... 👍👍🤞
I love your show
I have one bought from a Trader, looked as new, later on discovered it had no motor fitted.
Oxford Rail do not supply spares !
I am stuck as can not find any one who can help to supply a new motor or fix it.
One of my favourite Tank engines .
Regards JD in Kent.
I've been anticipating, and at the same time dreading the day you would be working on one of these.
Because on the one hand, I think you're one of the few that could probably make one of these notorious mechanical failures work.
But on the other, part of me thinks that this is going to be the one model that ultimately just isn't worth the effort, because of how many faults it has. I think Sam's Trains has had three motors burn out in one of these.
It's why most people avoid them like the plague, even when they're only about £50 - £60 to pick up.
good vid on channel thanks keep up the good vids thanks lee
Nice looking loco but clearly has an inherent fault somewhere, its coming to something when you have to redesign the loco on behalf of the manufacturer just to get it to stay on the track
An interesting loco - seems that some were loaned to the Highland Railway during the first world war. I may look out for one to convert into an LNER C12
I have had the same problem with a hornby b12 dcc socket; It also had a burnt out surface mount component on the socket board (capacitor?) Solved the same way. Sam's trains has experienced motor problems on both this loco and the hornby 5101. They appear to use the same motor.
Hi Bill, I’m thinking there shouldn’t be any direct connection from the wheels to the motor. The wires must first go to the chip then onwards to the motor. That’s most likely the reason for the chip to burn out. However as you wired the loco and bypassed the chip completely It should work unless there is now too much power to the motor. Just a thought.
H Bill I have only just seen the video and at time 13:58 I have seen that you have no spring and plastic washer on the front bogie as I have on mine.
Nice little loco
Shame about the dcc socket
Nick Australia
hi bill
hope you are well?
the oxford rail adam radius tanks and few dean goods have well know motor issues
that could be the issues i think
keep safe arp
Really great episode, interesting, and that front bogie issue, did it come from the factory like that, or has a load spring been lost at some point
This is a common fault with these and the Dean goods I just remove the fuse and rewire. The locos once electrically sorted run fantastic I have done this to around 20 Oxford locos
I think they've had issues with the motor Bill
hi bill i reckon you should run oxford rail. cant believe all these faults with the bogies,dont the clowns test a prototype before production.try contacting them for a motor, good luck, i am told hornby own them now, ! think i will seek comfort from Teddy,
There has been issues with the front bogie and the motor bill on other RUclips channels
Shame that there is an issue with the running speed,do you think someone rewired it up like that or was it a factory error,the 8pin socket should have been wired between the pick ups & motor.
Hugely frustrating. You’d hope they would test them properly before release but alas no.
Hattons says that this model has a minimum of second-radius curves, though Oxford's maintenance sheet doesn't seem to mention that. Were the derailments on first-radius?
It derailed turning out through points mainly. The model doesn't like 1st radius curves and tends to stop on them which is poor for this wheel configuration. I suspect narrowing the wheel spacing might help but I wasn't going to mess with that.
@@oobill It's certainly ironic that they'd make a model of this specific locomotive that doesn't like first-radius curves. The only reason that three of these (including the one modeled) survived 32 years longer than their 68 class-mates was that something was needed for the unusually tight curves on the line to Lyme Regis.
Hot air gun for heat shrink?
Machine mart do a good one suitable for this type of application, not much bigger than a lighter
How do I get in touch with you
Hi Bill. I own a Oxford class 415. Which I bought from a main dealer. Sadly after 5 minutes I lost the 4 chassis screws to the wife’s hoover. Could you or a viewer inform me as to their size. Customer Service is not that great from the supplier as the locomotives is not damaged. Thanks Sam
Look on Amazon or Ebay for M1 electronic screw kits. I don't know what size those screws are but they are likely to be less than M2s I think. So long as you get a kit of same type of screws I'm sure some will fit.
The radial tank always looks a a odd ball loco, tanks too short, large coal bunker, large over hang over the leading bogie + front splasher on the leading drive axle. As for Oxford I have a Yorkshire Janus loco. runs on track - but not on a rolling road! 🤔
the adams radial is a poor oxford model as are some of their dean goods thinks got so much better with their n7 tank and there j27 0-6-0
Nice one...I love mine❤🎉it runs beautifully @Tauraco00
