Fact

This year I have spent $60 dollar so far on LEGO.

Here is the frame I made to lock the motor in place with some epoxy known as JB weld. This is the most delicate and sensitive part, It requires patience and understanding of the JB weld. Note that there are magnets inside the motor and show what happens when magnets are close even the dried epoxy is has magnetic attraction. So I broke the lift arms of the previous motor to use on this motor. Because those two lift arms already had dried epoxy that saved a day. All I had to do was file down the dried epoxy so the motor and the gearbox fit together evenly. Having the pinion gear on the shaft and connecting it with the gear box made locking the motor in place a little less difficult then having no pinion gear. The most critical aspect is centering the motor shaft and securing it to prevent any movement when applying the liquid epoxy. I used a very little amount of epoxy here so that the motor magnets cant pull to much epoxy in. Now that the epoxy has dried up and locked the motor in place with the liftarms I will do some test. I will also make some pf wire wire connections. One of the benefits on this motor is push in terminals.

I think this would look awesome in teal. Black frame not red. And some chrome pieces.

At maximum efficiency In order to get started on picking a motor I first had to figure out how fast the RPM on the XL "motor" is to give me something to compare to. I pick this motor because it had the same 2mm shaft for the pinion and operated with in a 8-16 volt range. This is the motor that got replaced.

I have not done any empirical comparisons on the torque. So far the motor is half way completed. When the motor is together I will see if everything will work together under a load. That is a interesting comparison you made between the XL "motor" and this motor. I have done a simple torque test with me holding down the drive shaft in between my fingers and seeing if either one of the v1,v2 IR receiver will shut down power to the motor but that did not last for 10 seconds because the axle was hard to hold on to.

Here is another technical data sheet for the motor.

Here is some technical data on the motor below. I have power the motor through both v1,v2 IR receivers along with the AA reachable batteries in the 9v battery box and got around 1500 RPM (6:1 internal gear ratio) on the 5206 Speed computer on both v1,v2 IR receivers.

I have put the 12T Pinion gear from the XL "motor" on the new motor shaft. I heated up the pinion gear glowing hot and slid the cool motor shaft directly on it real quick. I had two metal spacer magnetically stuck on the motor to act as a barrier so that when I quickly slide the motor on the glowing brass pinion gear it will stop before the gear comes near the motor creating a space. I still am figuring out how to lock the gear box to the motor.

Here is a tip don't use your bed as a place to build. Otherwise you will be to tired to clean off your bed for sleep.

@Shadows: The danger message is gone now. Thank you for solving this problem. @Big Cam: Thanks for your help too.

@Big Cam: Yes the Warning is still coming up.

@Kierna: No it is not possible. If the XL motor case was one stud bigger length wise, then you could put a bigger motor inside but not two motors stack on one shaft. I dont know how to change the steel shaft or even know if you could change the steel shaft.

I get this every time I try to open my post up. Can a mod please fix this, here is the link below. http://www.eurobricks.com/forum/index.php?showtopic=78173

I took off the gear on the XL motor and there is a youtube video on how it was done. Not my video but that is how I did it. I did not have the precision of the torch lighter to get the gear off as seen in the video. What I used was a bulky propane torch which got the entire motor hot because of how big the motor was. The motor still works even though it got hot to the touch. Also I had the Motor upside down in the vise so that the pinion gear will fall down under gravity.

Here is the gear train that was used with the modified XL motor in the test. Note that the portal hubs were at a 1:1 ratio. This was made here http://gears.sariel.pl/ @jadedomg: Your welcome. Though the xl motor will not be as fast as the buggy motor, you will get a boost in RPM out of the xl motor by doing this. @allanp: I agree that they will never be as fast as the buggy motor. However the xl motor takes considerably less amount of current to run compared to the buggy motor.

After testing out the XL motor with the 6:1 gear I took apart another XL motor . I have tested both versions of the IR receiver powering this XL motor and with additional gear reduction a single modified XL motor can be pretty fast on four wheels, still not quick as the 5292 buggy motor. I have tried powering this motor with the combined voltage of two battery boxes but two AA battery boxes are to heavy for the single XL "motor". Additionally I have come up with a easy way to open the XL motor case and detailed walkthrough on how to connect the two planetary set together.

So far the crawler is the only set to come with a servo.

What is it that makes the rare parts rare? Is it color, design, or something else. For me the axle with tread and nut are rare and 11 length axles as well.

@allanp Thanks for correcting me on the planetary gear ratio. Appears that I have low battery power. The XL "motor" has some serious power behind that speed for its compact size. I have not tested the XL motor out with the 6:1 ratio yet. I will sure do some test on that before anything else happens here.

@DLuders: Awesome! After looking at that data sheet I wonder if there will be a V2 for the XL motor. Instructions on how to open the XL motor. With out breaking the clips off. If you are trying to upgrade the XL motor just break the clips off. First dig out one side of the clips with a small flat head screw driver... On the other side dig some of the clip out but leave some on there so the case can lock together... Watch the begging part of my XL motor video and try to open the motor like that... You will need to cut three 9mm length pegs from the tooth pick... -------- Wrap about a 0.4mm of the end on the peg with a small strip of tape.. Do not wrap the entire peg with tape because we want some of the peg to slide in on the other half of the planetary set...It is important that the tape is wrap around the peg in the right spot other wise you wont here it snap shut... It does not matter how much excess tape you have at the end that will be some of that will be cut off... The tape layer should not be thick two or three turn is enough... Make sure the pegs fit firm and secure and do not exceed the top of the plate... Make sure you hear it snap shut... If you do not hear it snap shut then the plantar set are not sitting even together.

The best way to handle this is the extra parts box method. This way Lego could revamp the rare parts supply.

Since I have no technical data sheet on the motor I resorted to measuring the motor shaft's diameter and it is 2.0mm. Along with the shaft size I have made some progress with determining the RPM on the motor shaft. I started by calculating the planetary gear ratio which is 1:25. When you multiply the 200 RPM output on the XL motor by 25 is 5000 and that is the RPM for the motor shaft. Now that I have some numbers on the motor I am able to select a motor that could potentially double the output on the planetary gearbox at 9 volts. @allanp: By your method of making it faster the gear ratio becomes 1:5. Have you tested the RPMs your modified XL motor, was it around 1000 RPM. @DLuders: Thanks for that link. That is the easy way opening the XL motor.

Hello, I have just took apart the XL motor to look at some things and see if it was possible to put the XL planetary gear reduction on another motor. The goal is to get more Rpm (@9v) out of the planetary gear reduction by attaching it to another motor. I have setup this tread to document this attempt. I did not want to break the clips off the case so dismantling the XL motor was tough. Currently the motor shaft is a little bigger than the XL motor shaft size. Is there any technical information on the motor that is in the XL.
