Default Remove Pinion gear

ok I have 550 motor that I am trying to remove the pinion from the motor and I was wondering how do you get it off? Does not have a grub screw. it is just on the shaft if wondering the motor comes off a starter box. Does require a special tool?

That's a permanent fit. I suppose you could try a torch and heat it up some and use a vice and crowbar. But I would remove the armature from the can unless you have spare bearings.

Yeah most of those are slip fit so they are usually locktighted on or some might be pressed on. If you don't need the pinion gear anymore then you can use lock cutters to cut the gear in half and it will fall off. Just be carfull not to caut the shaft.

That's a great idea! Use the metal cutter Dremel bit.

No need to put excess force on bearings this way.

Use a pinion gear puller. Those are press fitted.

Ok I will give that a try this week by my motor burn out so I order another one from tower hobbies. The funny thing is that the motor that came off the starter box was already set for the pulley inside meaning it had a lip on the pinion so the belt wants slip off ok. The new motor from towers has the lip opposite side of the pinion so I figure I guess they want me pull it off and invert it back like the one that came off the starter box. So that is why I am asking you guys what tool to remove so I can put it on the the way the first motor was. Kind of wierd don't you guys think.

It sounds like its a pressed on gear, you will need a pinion puller.

Here is a link what it looks like, that you could make.

They are available...but you can make one easy enough.
