I have an example of "Renown", in original condition but in a Rivarossi box, that I bought in Switzerland!

I have a Peco Jubilee that has been turned into a GWR County , two crankshaft pins are missing.
I bought this early this year and put in a new motor supplied from Peter`s Spares.

Do you mean a coreless ?

Worth checking to see if it is an early Jubilee from the first batch with driving wheels coupled by gears between the frames (turn upside down to check) if it is, then it only actually has the rods connected to centre and rear driving wheels (the rear pin sit in an open ended fork). The front end of the coupling rod has an impression of a pin which is stamped in it, but isn't connected to the wheels and relies totally on the gear-coupling to keep the front wheels in synch..

The Jubilee has a coreless motor , fitted in quite nicely .
The wheels are all gear driven and the coupling rods are not connected to the driving wheels under the cab.
The loco does run well.

is the coreless drive quieter than the original ? 
I need to do several--either dead or very noisy.

Only the first batch of Jubliees had the driving wheels gear-coupled, later ones did not, relying on rods alone. Yes, apologies my memory is obviously fallible, it is the rear-set of driving wheels that have no crankpins and rely on the gears alone to keep them in synch, the ones at the front go into the "forked" section of the rod, presumably to allow some movement to compensate for "slop" in the gears.

I have heard good things about coreless conversions, but never seen one personally, also, although requiring hardwiring and a bit of filing of the tender weight to make room, they appear quite straightforward to convert to DCC.

my main concern is fitting the worm at the correct distance on the shaft.

the only coreless conversion ive done is the TFK one to a minitrix dock tank--i fitted the worm too low i think and although smooth and quiet in forward--it hops up leans over and grinds along in reverse. Looks ridiculous.

I guess it depends how the kit deals with this part of the process?  Do you get a new worm to fit or do you have to remove and re-use the old worm? Does it use a shaft adapter sleeve? 

Just go slowly and gradually tap/press the worm onto the shaft a fraction at a time, keep re-checking until it's in the correct position.

Too low as in it's catching the rail tops or something? Or is the motor not fitted centrally?  The old Minitrix dock Tank / T3 mechanism was known for the axle bearings wearing to the point where the gear meshing became sloppy and the rear axle became wobbly, this was especially noticeable in reverse.

Too much free play in the motor output shaft between it and the worm  . No idea where the worm needs to fit so I guessed it .. wrong

i'm hoping to load pics of a couple of green Jubilees i bought --very reasonably--on ebay. Both were "non runners"--but luckily they run fine. I can only think the sellers didnt realise the locos and tenders must be clipped together to work !






apologies they are sideways--but i must applaud the talented modellers who painted and lined them.  Was it anyone on here ?

Usually I'd edit and rotate etc. before uploading.  However you can do it to your uploaded image.

Find the image in your gallery.  Edit it, then use the Customise Image "Add effects/Crop image" link and that will open a new window where you'll find there's a "Transform" button and then a "Rotate" button. Rotate the image then "Apply" and "Save" it. 

I just tried it on one of my images and it worked


1: Edit the existing image


2: Add effects


3: Transform


4: Rotate


5: Apply


6: Save


7: Done!
