Repowering old brass

[Attuvian]

Mel,

Would the Mabuchi be a reasonable replacement for an old Pitman in a '70s issue MDC 2-6-2? Also, can you imagine the compatibility with a good back-EMF decoder should this little beast ever be rigged for DCC?

John

Merry Christmas, all!

Thanks, Mel.  I've been following your comments on those motors, and was very surprised by the prices that were on the first Ebay seller's site that popped up when I googled the model number of the motor. 
The seller had included several photos of the motor, but it took me a while before I was aware that there were more photos than the one which was shown - I'm a very infrequent browser on Ebay.

The pins are needed if you keep the plastic endbell.  The plastic endbell can be removed to shorten the overall length of the motor housing.  I haven’t removed the plastic endbell in any of my installs.

 

The pins are shown in the first picture in my first post on this topic.  The pins press into slots on the side of the plastic endbell. 

 

The motors I’ve ordered haven’t listed the pins as an option.  The link below has good pictures of the motor, scroll through the pictures.

EDIT:

 

I would like to add that the Mabuchi SF-266SA motor is “my best find” in the last decade.  The motor is fantastic, equal to if not better than the Canon EN-22.

 

I now have 7 locomotives using the SF-266 motor, all 7 have dual motors and my four super heavy (34oz /11oz drawbar at wheel slip/630ma) E7s will pull the paint off the walls.

Thanks for that suggestion, Mel.  I found them at a really good price, but there's a click-on which asks if I want the motors with pins or no pins.  To what are they referring?

EDIT:  Never mind, the info was there once I took a closer look.

Running them back to back I can’t tell the difference in the Athearn frames.  As my Cab Forwards didn’t have flywheels the dual motor easily makes up for a flywheel.

 

I haven’t installed a SF-266 in a regular steam locomotive but they don’t need flywheels in any of my installs so far.

Thanks Mel,

Good call on those motors. I remember we used those for things in r/c stuff so I don't know why I didn't think of that for repowering. 

I'd like to stick with something with dual shafts for flywheel options but I'll check those out!  Thanks!!!!!

Look into the Mabuchi SF266SA motors.  They are very powerful with a 2mm diameter shaft.  They do not have a skewed armature but they have 6 poles.  The price it right too, under $3 on eBay.

 

 

I have installed 12 so far and got ten more last week.  They are small enough to fit back to back in an Athearn SD40 frame.

 

They work great in Rivarossi articulated.  Below is a Cab Forward and a kitbashed Cab Forward into an AC-9.  Both run great.

 

 

They have tremendous power at very low current.

 

Here is a pair in an Athearn SD40-2 frame.

 

 

I compared them to the Canon EN22 and they are at least as good if not better.  Their low speed torque is great as well as smooth from 0 to max 6000 RPM.

Hi guys,

Looking to repower a beautiful old Westside Brass SP Daylight. I really like the price and performance of the Kato motors but can't find any specs on the HM-5 motors.

Can anyone recommend anything else?  I've looked at Mashima but at $85 a motor, I think I can do better for power with a stock set up out of another mass produced loco like the Kato.

Thanks,

Mike
