Do you think it would be ok to use 2 of the old ones in conjunction with 2 of the new ones in a 4 wheel drive system or would it be better to use 4 new ones if the power difference isn't that much?
Edit: saw it was a different poster with the above q.
Yohooshi, do you mean the old Argos drill and a new Argos drill?
I do not know the differences in the old gearbox of the previous Argos drill motor, therefore cannot say. If the output speeds vary then your robot will always turn to the slower side.
if the speeds differ, best to get 2 new drills and save the old 2 for a 2 wheel drive bot...
If you mean the old style end cap:
"
It would just be the design of the bit of metal making the back plate, the coils should 99.999% of the time be the same, therefore should be fine."
Past experience with lots of dc 12/24v motors with multiple designs are the basis of my knowledge.

As I mentioned in my post the old motors are slower with a 36:1 ratio vs ~28:1 ratio in the new drills. You can't really use 2 old and 2 new together. You could use different size wheels to make up the difference but frankly that's just awkward. :POriginally Posted by Yohooshi
ALSO, since I have you here. I have this a very old Bosch 14.5v

It has the same back plate as the new Argos and doesn't stay connected to the gearbox/chuck.
The old style mounted easily. I'm struggling to find a way of mounting this.
suppose I should add, I can't remove the chuck part, ive tried!! but I have managed to connect a sprocket and the clutch will be handy as it'll power a flipper/lifting arm.
thank you again!
Do you have a 3d printer? i have made some mounts shown in the video i have on the esc pages -
It has the motor sat on it - the black block, its a version 1 mount but holds the gearbox firmly. I have a mount for the motor can too, but that is not shown in the video. I can send you some if you want? send me a PM
Sadly no!! But by watching you video, the motor itself looks like it does connect to the gearbox. I must have misread your review and was panicking over how to secure them both together. (the problem I have with this Bosch motor)!!
Might just get one to have a proper look myself. But don't go away, I might still end up getting some mounts from you!! mounting the old style did get rather annoying!!
The motor is attached to a plate in the gearbox but that plate just twists off, you can see this in the pictures on the review. I didn't remove ANY screws from the gearbox to disassemble it like that.
Where are you located? i could scan the motor and gearbox and produce a mount for you, but i would have to take it from you and scan at my workplace. Could you send it or make a drawing? i may even have a bosch somewhere... will take a look. What is the model?ALSO, since I have you here. I have this a very old Bosch 14.5v

Whitchurch, Shropshire. No where near Hampshire!! As for the model, I will have to get back to you. The case is lost in the shed!! Main problem is stopping the motor spinning itself in the normal mounts pictured above. AND keeping it secure in the gearbox!!
On the first page to the thread its the same as the picture on the right!! Two little notches, (which the case would keep still.) but it also has the back end of the axle sticking out. (assuming that needs to the keep clear so it can rotate freely!)
AND yes, I tried to remove the reverse thread screw! But the 3 bits that hold onto the drill bits wouldn't separate enough to let it out. So I've managed to get a small chain sprocket in and I'm happy with that now!
image.jpgimage.jpgI meant can you send a picture of the gearbox with motor end on, so I can see it's profile, not the end cap of the motor.
If it is the same as mine not the one I have pictured then I could help and design something for you with your measurements.
The mounts I have lock around the case of the motor and slot into its external cover locking it into place stopping it from rotating out.
