Changing coarse wheels for fine on old rolling stock

[Jimbo1707820979]

Apologies for bringing up this very mundane subject. However, I badly need some advice as I have several coaches to convert, including the exposed-axle, split plastic covered ones on the Triang Intercontinental range. I already converted several Triang "shorty" Pullmans with the "non-exposed" axles - easily done using R 8096 12.6 mm wheel/axle sets.

Unfortunately many of the Triangs have exposed axles so not a straightforward job. I watched John (chambs123) video on uTube which was exteremely helpful but as I am completely deaf left some questions unanswered :

1. What diameter drift needed and if there is a way to loosen the axles. Mine are seized pretty tight and I don't want to break the mountings.

2. John appears to use "Romford" pinpoint replacement bearings. Should I use the "shouldered" or plain type ?

3. To secure the new bearings Jon appears to use Blu-Tack, finalised with super glue. Is my understanding correct ? Or is there something better.

4. What size wheels should the new ones  be ?

P.S. If you are wondering why I didn't switch on the CC (sub-titles) these are worse than useless as horribly garbled on most uTube videos -unlike TV, which are good. Thanks for any advice as I,m groping in the dark.

Hi jim, i too have watched his video, he uses both the shouldered and plain, the plain ones he uses with open axle boxes, and the shouldered ones he uses with the closed boxes, have you left any comments on the video page, you need a you tube account to leave comments, he uses the bluetack to set the bearings and the superglue to hold it all in place, the way that he has done means that if they need to be changed for some reason, they are easily removed, hope this helps,

Hi

12.6 mm are the right size for trucks and coaches in trans con range and other Triang rolling stock.

Yes you need to carefull when kocking out the axels. The best way I found was to find the fixed wheel on the axel (there is a two small wings on the axel which holds it in place in the wheels bogie frame) put the coach or truck on itd side with the fixed wheel at the bottom then gently tap the axel out. (tip) Get a piece of wood and drill a 3mm hole into it put the axel over the hole and knock the axel shaft in to it. On some trucks I have done the axel wings are been on oposite sides.

I used shoulder bearings, on the plastic bogie frames I found a smear of petrolum jelly held the bearings in place whilst fitting the new wheel sets, I have yet to do the metal bogie framed ones thinking of using both shouldered and plain in opposite pairs.

Many thanks to Dynax and Tony. Of course, I meant "Trancontinental" - Intercontinental clearly a throwback from my

export travelling days. Ah, nostalgia creeping in ....ouch !

Anyway, your advice really helpful and this old relic will proceed with saving a few more now.

To find the "fixed" wheel on the axle. (Sleeved axles, Open Axleboxes)

Hold one wheel, while turning the other on on the same axle.

Look at the axle ends in the axle boxes.

The wheel that turns the axle is the fixed one, which is engaged on the "Splines".
