Rivarossi seemed to alter mechanisims quicker than packaging, but if
yours is like mine (central motor - cardan shaft - tower gearbox on one
bogie - gears to axles - cardan shaft between bogies - etc) then you
just toss the Rivarossi motor where it will never be seen again (keep
the universals from the motor shaft!) Mount a new motor such as a Sagami
(or anything chunky, it has to be better than the Rivarossi) using odd
bits of Plastruct and silicon sealant and fit the universal onto the
motor shaft. That fitting is the difficult bit, because more than likely
the shafts will be different diameters. Probably the replacement motor
will be larger than Rivarossi's, so the universal will need opening out.
If you don't know how, then ask. Your local hobby shop will probably
know someone who can do it for you.
The only replacements you'll find are in old Rivarossi locomotives.
Rivarossi hasn't used that old motor for quite a while. AHM imported
them, so when you search for these old locos on eBay, you should also
take a look at AHM locos.
You might want to look at NorthWest Shortline.
Give them a phone call (number is on the web site) (Area Code is 360 IIRC -
US Pacific time zone) if the really really extensive on line catalog
NWSL probably has a good can motor rplacement and great gears and worms.
The Rivarossi mechanism may need a fine tuning.
Greg and others...appreciate your input...despite being forewarned (and
after 40 years fixin' up H0, I should have known better) I foolishly took
apart the motor and found the ball bearings have a mindset of their own and
I lost half of them. Other sources advised me that the exact number need
be installed else motor will not run smoothly. Checked one site that sells
machine tools & parts etc and for 1 (ONE) 1 mm stainless steel bearing
they wanted almost $16.00 or 10 tungsten carbide ones for $16.50.
I may just have another icon for my display case. :)
