I am trying to make a gear puller for my Bosch 36 V cordless drill
motor. I must use that motor with a different gear. A DeWalt 18 V
right angle drill motor gear will be used in its place.

I would really rather buy a gear puller. Is there anything for
pulling small DC motor gears off?

If not. Is there an easy way to make a small gear puller like
that?

Thanks.

Sure, visit just about any RC vehicle parts site and you will find
pullers for small stuff.

The RC hobby is a great source of parts.

Check out their battery options for when that Bosch cordless drill
needs new batteries.

TMT

A short section of heavy wall tubing (round or rectangular) can make up the
frame/body of a small puller, by adding a slot at one side, and a tapped
hole located 180 degrees from the slot.
I've seen small round frames that have a flat cut from the OD where the slot
is located to allow the "jaws" (now tapered) to fit behind a gear with very
little clearance space behind it.

A locking shaft collar (setscrew type) will make a sturdy frame, and already
has a tapped hole.

Add a screw to fit the tapped hole.. bazinga, a small gear puller/miniature
screw press.

Filing/grinding the tip of the screw, or better yet, reducing the diameter
of it to slightly smaller than the motor shaft size in a lathe, and the gear
will pull off almost effortlessly.
If the fabricated frame is durable, it may be worthwhile to make more screws
with other tip sizes for other purposes.

In the R/C world, the small gear on the motor shaft is referred to as
a pinion. If you search for "pinion puller", you'll get lots of useful
information. Here's a picture from one of the hits:

It's probably faster to make than to buy.

Like the nut cracker I made several years ago from a piece of 2" heavy
wall tube, drilled and tapped 1/2 - 13 for an extraneous hood pin.
Eventually the threads on the hood pin wore out so I substituted a
high quality (#5, #8) bolt; it is still in service. much less damage
to the kernel.
