Fixing a 9v Lego train motor with a PF lego motor (Part 2)

[Lazarus]

Hello All.

For more info you can view my first thred but this is a bit of an add on to that Plus some extra stuff.

(Story)

I bought a damaged 9v off Bricklink last week as I knew I could fix easy and cheap 9v motors are hard to get. I opened up the 9v and PF motor as I have done 15 times already and start the fixing process.

What I noticed was something that i did not expect, there was a diffrent internal motor. At a quick looks you cant tell but what I found just made my life so so easy.

(What I found)

So if you look at my first thred there was a comparison between the 9v internal motor and PF motor and how to modd it to make it fit into the 9v Case. And every motor I have done to this point have all been the same.

But this 9v motor had the same internal motor external case as the PF external case. What this means is this version of the 9v motor you can just streight swap a dead 9v internal motor with the PF no modding needed.

Pics below.

On the left side is the normal internal PF motor on the right is this new what I am calling the Uncommon 9v as this is the first out of the 15 9v motors I have that is like this.

We have two 9v motors above left is what I call the Uncommon and Right is the common, Only diffrance is the plastic (shell) just behing the gear as you can see it is the same as the PF shell where the common 9v is smaller and thus the 9v case it self is diffrent and the PF motor wont sit right as explaned in my first thred.

------------------

NOTE #1:

I am also going to be looking closly at the outer case of the common and uncommon 9v motors to see is the is anything on them to tell the diffrance without pulling the motor apart.

NOTE #2:

I am also working on making it so I can run these motors off the PF remote and it drawing power from the 9v rail and no a Battrey box.

I have made a protype that is working well, I am now working on a clean version that will have pics soon.

Well just did a bit of huntting and found this info what we all know and just think they are the same motor.

So i think 10153 is the "uncommon" and the 5300-1 is the "common'

10153: Train Motor 9 V

- Out between 2007-2009

5300-1: Train Motor 9 V

- Out from 1991 with train sets

So are there actually any external differences between these two types of train motors, or do you just have to know when they were made or when you bought them?

Still working on find that info when I get home from work :-)

Thanks for your continued hard work. I am slowly amassing a collection of dead 9v motors. I haven't opened one yet, but I figure I will start following in your footsteps in a few years.

According to Bricklink, the 10153 set was released in 2002. I know that towards the end of the run the 9v sides were replaced with the RC sides that have the notch for the technic axle. It is quite possible that about that time Lego switched the internals over too. At the time I was not paying too much attention to the subtle differences in train motors, but I have a vague recollection of folks on Lugnet discussing how the seal on the bottom of the 9v train motor changed somewhere around 2004-2005. That could have also been when they changed the internal motor. They do have a history of changing parts like this and keeping the same part number (e.g., version 1 and version 1.1 of the PF receiver... though that time they did tell the AFOL community because it also had a slight change in functionality).

Thanks about the pins I will look at that, should get around to doing stuff 2nite, kids and wife getting in the way :-).

I know the casting of the top half of the body at least would of been remade or changed due to the above differences.

I will also test out the PF gearing in this one to see if I get the same slipping issue i was getting with the other 9v motor.

Ok bad news, no external differences between the two versions :-(.

Kinda sucks coz I just completed my 2nd PF controlled 9v and it came out very clean and runs really well.
