Hi guys. Does anyone know how to re-gear Hornby engines? I am thinking specifically of the J94 and Terrier, that are fitted with low gears. I would like to be able to run them at higher speeds. Does anyone produce the conversion drive, or should I just try various bits and hope? Thanks.

Hi Fireline, I am sorry i do not know or even think that you can change the gears on those locos but like Brian said why would you want to make those engines that are normally used for shunting and short distance running go a lot faster!!.


Sorry i couldn't help but still enjoy the forum i know i have already got a lot of pleasure and information from here.


Kind regards

Paul

I don't want to massively increase the top speeds, but as I model a preserved line, I would like to be able to run the engines from one end of my line to the other a lot quieter than I can now with the present gearing. All I want is to be able to create a similar gearing to the recently updated Jinty. I certainly don't want to model 100mph running with a Terrier!

Have you tried lubricating the gearing. I also have sometimes with louder locos put plasticine in side the body to deaden the sound (if you can fit some in).

Try using some vasaline to lubricate the gears that might help.

Kind regards

Of the two models mentioned, I only have the J94. For such a basic mechanism it can actually be got to run quite sweetly and quietly under DCC control (Lenz silver in my case) with extra weight on board; most of the cast ballast having been replaced in lead. As an aside, unless your preserved line is the GC section near Loughborough, top speed n the UK is restricted to 25mph under the light railways act. And the maximum speed of the model as supplied well exceeds what the prototype would be capable of, mine would get up to a scale 90mph.

To improve on the drive, it would be possible to replace it with a fold up gearbox and better motor. Branchlines, Comet, High Level, and doubtless other makers; all will have combinations of box, gearing, and motor to fit and deliver whatever improvement you seek. That would likely come in at similar cost to the purchase price of the complete loco. There may even be a kit to build a replacement etched chassis, with more accurate wheels as well, if you want to go the whole hog on the mechanism.
