Removing press fit gears
Hey everyone
Just got my DeWalt's from the RMP and need to remove the front gear that is press fit on. Its similar to the RS550's that come with drills, only it seems to be held on more tightly held on. Is there any way to get the gear off without rooting the motor ? _________________ Jeff Ferrara

OK, I assumed you were getting the matching gearboxes
You will need to make or buy a mini gear-puller (Google it...) depending on how much space there is between the gear and the motor, getting the gear off could be quite a challenge.
The best place to start looking seems to be an R/C car shop. _________________ Australian 2015 Featherweight champion

Heat the pinion gear up with a butane torch and then use standard methods of removing the gears. _________________ https://www.halfdonethings.com/

I will have the same dilema when my motors arrive any day now.
As I have stuffed up a few motors in the past, (Mainly Mabuchis as The splined Johnsons are easier to remove) have at the moment the idea of removing the gear by using a small cutting disk on the dremel.
I know it doesnt sound pretty but not going to risk damage and dont have a gear remover so grind the mongrel off I reckon.
Wish I had a gear remover to be honest but there is a slim chance the pinion gear might match as is. yeah right. _________________ Bots that do not destroy you, only make you stronger.

Go and bye a good gear puller designed for small gears. much cheaper than stufing up the motor.
Taking gears of with out the correct tools is a bugger of a job. It can be done, but not wearth it.
The V clamp style would be the best type to use.
A bearing supplier should have one that will do the job, or a good engineering tool shop.
If you find you are still having troulbe getting it of, with the gear puller. get a Black & Decker hair drier, or the $20 one from Bunnings (the type that melts hair.)
have the gear puller set ready to take the gear off and heat up the gear. Once the gear is nice a toasty, start to use the gear puller and take the gear off. _________________ It's all about the destruction.

I cut a slot into a peice of metal just wide enough to take the shaft. This supported the gear. A thin punch was used to tap on the end of the shaft. It was easy.
