Hydraulic Heaven

Perhaps a scratchbuilt chassis is going to be the answer. You could look to see if any of the US N diesels have a suitable chassis but would still have to convert it. In the 'to fix later' box I suppose I have quite a few things in mine.

I recently had a Hymek on the workbench to try and fix it and encountered exactly the same issues. Removing the circuit board caused the chassis to fall apart. and after looking at it I concluded it was down to poor design and casting. The dummy loco route was tried, but proved an expensive dead end as the chassis in these is plastic and doesn't have all the gears either.

 

Eventually I managed to glue the original chassis back together aided by plasticard, but also hit the gear meshing problem. Turns out there is just too much gearing play everywhere in the gear train, but especially here, the worm shafts almost going their own way within the worm housing. The answer was to sleeve the bores with brass tubing to remove the play since there wasn't the room withing the chassis to use top-hat type bushes in the housing.

 

Non of this was ideal but got the loco up and running to a fairly reasonable level, and you may be able to do the same. However to be honest the body deserves a decent chassis/better motor combo if it should prove possible, but this would take some time and effort to produce even based around the current bogies as finding anything with the same 10' wheelbase might prove difficult..

 

Good Luck!

Hi, BR Lines are listing wormwheels in stock. Have a look in the Dapol section. Andy.

I'm thinking that some sort of repair is probably the way to go but it'll need to fix the meshing issue as well as making some sort of splint for the broken chassis half. I did consult my Kalmbach book of US diesel drawings (purchased a long time ago in the US for exactly this sort of question) but as far as I can see there is nothing stateside with such a long wheelbase 4 wheel bogie (truck) and the Hymek wheels are pretty huge too.

Thanks... and commiserations too. Thanks for the steer on the dummy loco. Until the recent issues, I've always found my loco to be a good runner so I don't have too many worries about the motor.

So they are! Last time I asked them I was steered in the direction of DCC Supplies who are now the official Dapol spares people (but don't have anything in stock to solve this problem). Thanks for the tip!

Oh no!!  :-(

 

Which one's the Hymek? :-) - they don't have a pipe coming out the top for the smoke and shiny brass bits adorning their upper works so they all look the same to me :-)

Which one's the Hymek? :-)

It's the one that isn't quite typical for a layout set in Cornwall in the mid 1960s....

 

No, wait...

I just transpose the "6" and the "0" when I'm operating :-)

Hello D869

If you still have this locomotive, please contact me.

If it's n gauge, then I have the parts. If it's OO gauge, then I'd be interested in buying it.

All the best,

Rick
