Terry,

Snip

I had problems with my Pacific soon after I bought it, because the motor melted the mount

Snip.



A few months ago I actually opted for a much cheaper motor. This is the motor that is used in the IHC GG1, and it's actually smoother and quiter. It has a low top RPM, so that the speed range is realistic even with the original gearing. I had to lay in a cab floor, and hog a tremendous amount of plastic out of the boiler and firebox. There was barely enough clearance for the screws that hold the firebox together, as I had to grind a lot off the the screw bosses as well.

 

You've done alot of work there and it looks  like you added some weight

Nice Job !

The motor mount on one side of mine was heated to the point of being brittle

I'll have to reinforce it some how

Also when i took the old motor apart one of the brushes was all but gone

I don't really know how it even ran

 

I am mainly after the less current draw

Hope this motor will be as advertised

Terry,

Nice tutorial. Cv-backshop has some nice retrofit kits, and his instrutions look great. Being cheap, I would just use one of the own motors I've salvaged and drill holes in the plastic mount and screw the motor to it without cannibalizing the old one.

I had problems with my Pacific soon after I bought it, because the motor melted the mount. Years ago I put this Sagami in it, but it was a high RPM motor, and was too noisy.

Once you drilled out the old bushing you can use some silicone

glue to glue the new motor in side the old shell

Included in the kit is a new drive shaft

Using a dremel I cut it to length and the universal joints

 just tap on with a hammer

 

You can get these kits on Ebay

I got mine from

http://myworld.ebay.com/cv-backshop/

The instructions are good and easy to read

the work can be done in under 1 hour

You also remove the Magnet ring

and use a 3/16 bit to drill out the old bushing

Part of the conversion involves remotoring the loco as the newer motor draws far less current

The new motor fits right inside the old motor housing

The Motor is held together by 2 bent tabs on the side of the housing

 

 

After Prying them straight You remove the insides to make room for the new motor

Not much room in the Vandy tender for a speaker

I've been searching the web for a "How to guide" with pictures

for this project but so far no luck

I did find this link for Rivarossi drawings on the HO seekers site

http://www.hoseeker.org/ahminstructions.html

And a remotor how to on the NWSL site

Tonys trains has some links for how to sites

on page 7

http://www.nwsl.com/Catalog/pg047-cat4-19-v0605.pdf

But nothing for a Rivarossi Heavy Pacific

One of the sites has lots of locos

But again nothing for the Pacific

So it looks like i'll be flying blind on this one
