I am about to do this too.

Here's my question,

On ebay i see TWO motors.
One with just a round shaft for .99 cents
NEW / replaces Mabuchi FC 280PC-22125 and FC280PT-22125 - eBay (item 270717876995 end time Mar-16-11 13:11:13 PDT)

and one with a "Collar" on it for 8.90
MABUCHI MOTOR FC-280PT-22125 DOOR LOCK ACTUATOR REPAIR - eBay (item 120686174761 end time Mar-18-11 23:49:58 PDT)

Nobody has really addressed this collar? Do I want the 8 dollar one here, or is that collar going to come off the old motor?

I also read that someone completely swapped the old shaft in place of the new shaft.

Just though I would ask first.
:rebel:

^Just get the first one. If you look at the picture I posted (Post #17) There is a worm gear that goes over the shaft. So the other collar would be pointless really, I think. They are both the same price anyway so I don't think it really matters which one you get, so long as the collar is removable.

Go without collar

It's removable (press fit) but why deal with the hassle? Get the motor without.

Just be aware of what posted above

Now on to the Mabuchi motor. I could not find a motor with a flat shaft on eBay (even though it was reported to be the case) So I wound up just dismantling the old and new motor and swapping the shafts. So old shaft goes into the new body. It worked just fine for me. I suppose you could try swapping the brushes themselves out, but this seemed like an easier approach.

i got 2 motors of ebay and both came with round shaft. emailed seller he said they do not have it nor anyone else has them (that he knows about). bought a file for $4 and 15 min later (taking my time) it was perfect fit.
it was easier than getting the actuators out of the door. I tried not to mess with it too much, just unscrew and move as little parts possible, put it right back.
things work!
total cost $17 for 2 door locks. (including $4 file :)

glad this is helping people fix their door locks and saving them money.

i updated my post to remove reference to the motor with the flat-shaft. It appears to be causing trouble/confusion. and it seems like no one has actually found one that works.

it seems using the dremel or hand-file makes the most sense because it has been tested.

Just fixed my bad actuator due to this awesome post.


Now on to the Mabuchi motor.

So old shaft goes into the new body. It worked just fine for me. I suppose you could try swapping the brushes themselves out, but this seemed like an easier approach.
Was it pretty straight forward swapping out the shafts? How hard was it to do? I just received my new actuator motor for the lock and if i can just swap out the shafts that be a whole lot better for me.

should be straight forward. but if you are at all worried, just grind the shaft.. just do it slowly until the gear fits in...

Thank you, Thank you, Thank you for these threads. I could not have made this fix without all of this valuable info.

Here is a decent pic of the clips n rods insatlled


To secure the motor housing, I used 5-minute epoxy. I just put it in 5 locations around the seam.


This helped me a lot. I just put one of the bold in and I held the door lock module up while I worked on it.


I did have some challenges along the way.

This is when this tuned bad.......see the 2 cracks, this part was bad. What to do.....


I decided to try and fix it. So I made this part to replace the rod mount.


Here is my new rod mount.


and here it is with the clip in it.


Thanks again to all that have made these threads, it was a great help to me.

Due to the issue rms2k ran into above, I have to go back in there once my new (used) door handle gets here tomorrow..and once put everything together and tried to lock the doors there is an extremely loud buzzing sound coming that door. Is this because that housing .is coming loose or did I put something together wrong ?

I've read about gluing or zip tying that piece, I'm hoping that's the issue

Just tackled this project today, took me about 2-3 hrs from start to finish. The rod that was attached to the white clip was the hardest since the rod has more of a ball like shape at the end compared to the other rods. With some force it finally came up, luckily i didn't break anything. The second time consuming thing was shaving the mabuchi motor since I don't own a dremel. All it in all easy fix for only $5 bucks and a few more dollars in a couple tools, beats having to pay $100+ for the whole part. Thanks for the write-up.

Well, I tried to fix my passenger door lock following this instructions. I must've put the parts back wrong, because when I closed the door, now I can't open it anymore from the inside or the outside. I feel like a complete idiot right now. Anyone can help me out? I feel like I made a really boneheaded mistake, the linkages are not aligned correctly which is why the locking mechanism that locks onto the latch is not releasing anymore... I think I'm going to have to pay through the nose to open it up again huh?

Either the rods that connect the lock assembly to the handle was reassembled incorrectly, or the linkage between the actuator and the lock assembly was reassembled incorrectly.
