There have been past threads on these tools and a number of the links referenced no longer work. Here is one from Micro-Mark and I am curious if anyone has tried this. Thanks for suggestions or thoughts.

Many threads on this subject, however, I have that Micro Mark tool set, and it’s kinda cheesy,….not one of their shining stars IMO, ….if you’re in the market for a wheel puller, I’d suggest looking into PE Design’s wheel puller ( and other tools he offers) I have quite a few of his tool sets, these are made in Paul’s home shops, these are all made from the real deal “tool steel”

I have the Frank Timko wheel puller, it works well for me.
I also have a Great Planes Gear Puller, it's the ticket for smaller gears and worms. For this one, I cut a bunch of steel tubes to be able to accurately position the screws, and I also have several sizes of screws for various sized worm gears.
One issue I had was bending the pin on a stubborn work gear, Pat (Harmonyards) here made me a pin with removable tool steel inserts that should solve that problem. 
For any gear/wheel puller, lubing the jackscrew well is key, it makes things go smoother.

I did a pretty good review of pulling the wheel and replacing a gear. The review also covers the wheel puller I bought and used.
Take a look at this thread.
Does anybody know if either of these pullers will work to pull the gear off of the armature gear on humpback motors? I have been cutting them off with a dremel tool but have to be very careful.It looks like both pullers above might be too big to fit or if the gear is too close to the frame that jaws will not be able to get under the gear

I use the micro mark tool only for light duty jobs such as pulling the coupling hub off of a Hudson (783,784,785) worm shaft. It will easily bend using on drive wheels or any gearing. Go with the suggestions above if you are going for gears or wheels.
Thanks for the feedback. @Renovo PRR I missed those threads in my search- heavy duty work you did! I should have been more specific, I am simply trying to see if I can re gauge some rolling stock wheels but it never hurts to have capability like that.
Pat, I googled PE designs and that is a nice one for sure...and it appears it is $59 or so. I wanted to compare prices with the one GRJ recommends from Timko. I had looked at Timko's web site previously but I could not find any tools for sale. I plan to send him an email to see if he still makes those. Looks like if I am going to make this leap, might as well get a good one as Rod notes.
Thanks again, I will pass on the micro mark one and I will repost when I hear from Timko.

Jim, I think you will find PE Designs has a specific tool for just about every job needed to repair post war trains and newer. Very well made and clever in design. Well worth the price tag.

My Timko wheel puller was $39.95, and shipping was $7.15 for Priority Mail. You have to call Frank to get it, it's not listed on the website. The Great Planes Gear Puller was actually cheaper, but I added a bunch of stuff to it to make it more useful.

The old saying rings true even in our hobby: good tools aren’t cheap, and cheap tools aren’t good…..😉

Update- heard from my email to Frank Timko and, although not on the web page, he is still making the pullers. Tough call on which of the recommendations to get but I went with Timko.
Thanks to all for the help.
The Timko puller is very good. You'll still want to consider a different style if you're pulling small gears or worms, that's why I went with the Great Planes gear puller as well.
I might have missed it where would you get the TIMKO - I end up destroying the gear on the armature everytime so far

Dave, pulling worm gears is the most difficult job you'll likely encounter. If you want to get a gear off a dead motor, just cut the shaft and you can set the gear on a block and pound the shaft out. If you're trying to get it off a good motor, then heat the gear with a heat gun nice and toasty warm and then apply the pressure with the puller.
