Noise reduction tip for X03 and x04 Triang motors.

- I hate noisy motors. Alot of the noise from Triang stems from vibrating axles of commutators in worn brass bearings. I have found this solution is effective in reducing the growling sound. I use white lithium grease and found it lasts fo 2 hours non stop running so far. I would be interested to know if anyone has come up with other solutions.
The bearings are phosphor bronze, not brass.
The position of the worm, on the armature shaft, determines how much growl the transmission will have. Repositioning the worm forwards or backwards a millimetre, will reduce the noise generated by the transmission. Triang-Hornby were aware of this and changed the axle cogs from brass to delron, then to nylon in an effort to quieten the locos down.
If the loco growls far more than the average Triang-Hornby fare, then the loco was assembled on a Friday just before clocking out time.
The Hornby Dublo R1 0-6-0T can also have a noisy transmission, if the worm is not quite positioned right.
Thanks for the info, I wasn't sure of the bearings. I have watched OO Bill do the adjustment on the worm gear, I have done that to prevent wear on a few motors. But I have found the grease fed into the rear bearing makes a substantial improvement in noise reduction. Thanks for the comment, much appreciated.
More likely wear on the centre or driven axle, you can see it wobbling.
Moving the worm on the motor shaft shouldn't alter anything. Try shimming the centre axle to improve running. The 'cog' is actually in principle a worm wheel, but in Hornby's practice a helical gear.
This is interesting.
Oiling the bearing pads is supposed to lubricate the bearings.
Out of interest, the front bearing pad on your X.04 motor looks clean and dry?
Thanks for the tip.
The hard thing for a lot of us is not having a rolling road to lubricate the armature shaft while the engine is hot and in motion.
Hi mate, you could try removing the motor and putting it in a clamp and then run it. My front bearing was oiled, I don't put the grease at that end as it is not conductive and leaks onto the commutator. I don't soak the pads with oil as it attracts dirt, a couple of drops is plenty. . The grease has enough viscosity to stick around in the bearing for quite a few hours of running time. I hope you give it a go. Steven.
Hi Steven, the noise from these motors is something I have not worried about before but as you will see on Tuesday, I have a 2-6-2 tank that is very loud so I might give it a try. David.
Hi David, it won't be a permanent solution, but can be reapplied as necessary. It has really made a difference to most of my noisy X04s. There are one or two where the results have been not as effective, so I am continuing to investigate the cause. I suspect it could be cooked wiring in one of the poles causing an imbalance when it runs. May need a complete rewind. Steven.
Hi Steven, looks like you found a good solution using Lithium grease on the noisy rear bearing. It is definately quieter and smoother running. Cheers, Paul.👍👍
Thanks Paul, after a bit of experimenting I think I have found an acceptable solution. Steven.
😊I would be more concerned about the middle drive wheel .
I have looked at it and decided to leave it for now. If I ever get hold of some new insulators, I will replace it. But as this loco spends most of its life in a cabinet, I may die before I get around to it.
Hi Steve I,v always put oil on the rear bearings, but I think grease would
Provably be a lot better. All the best butty. Carl.
Hi Carl, give it a crack mate, I am finding it works quite well. It's a cheap fix. Apply very sparingly if you do the bearing near the commutator. Steven.
Hi Steven.
Good solution but the question is, how often will one have to apply grease?
Paul. 🤔
Hi Paul, well that may depend on the number of hours the motor is used and how worn the bearing is. The grease I used seems to stick pretty well to the gearshaft and bearing. The phosphor bronze bearing is porous so it should absorb into that as well. I haven't had to repeat the treatment yet, so I'm not sure how long it will last. Steven.
Awesome video m8.. Ive never seen anyone explain tgis before not even OObill or sam on sams trains. I only bought some white lithium grease just like you did somI will go,through my x03 x04 motors and check them..
Can you still buy the brass bearings for the x03 x04 motors and do they have a R.??? Number for them as I have already bought the plastic bushes for the triang axles.
Thanks again for good video.
Cheers from John in Australia
Hi John, I'm in Brisbane mate, so I'm not sure about the bearings still being made. But if you look up Mr Snooze's channel, his latest vids address this very topic about replacing bearings with substitutes. He does an excellent job as well. I'm glad the vid helped, it's just a simple method that can help reduce the vibration of the shift in the bearing. Steven.
check peters spares
Just look at the front and centre wheels spinning up and down (eccentric)
I see what you mean, this is usually from the plastic insulators on the axles softening, or wear in the axle bearings. It's an easy fix, if you can get the insulators.
It looks more like a Pittman motor than a triang motor.
Definitely an X04, but both look very similar.
@@stevenpeaketrainsandstuff3682 Yes, definitely! in fact it's almost a dead ringer, oh. by the way, thank you for answering my comment.
@@michaelquinones-lx6ks No worries mate, have a good day. Steven.
