What is your favorite Pinion Puller/Press?

[MoparGreg]

I use a hudy puller. Its been good but sometimes the gear is to close to the motor & the ends of the hudy wont fit in the gap. Otherwise its all good.

For a press I use my bench vise. Works well

well, after hanging around with Dickie, i thought pullers were lawn tractors!
and as for pushers, well, ref: Steppenwolf. or maybe those trucks with the wooden bumpers and the hook on the back, that sometimes bang into your rear push bar so hard on a dirt track, it snaps your darn neck. oh wait. they were called Presses. anything to do with a bench? or a full court?
sorry about that, Chief.

but seriously, though, i've accumulated at least a dozen Gear puller/pushers over the years. the best one is the hudy because of the aformentioned alignment, if it fits where you want it to and i haven't ever bent a shaft with it or slid an arm in the can.
but i do have a set from the 60's that looks just like those black metal hoodie ones at the top of the post. i use them a lot because they're easy to use, always ready (no reconfiguring) and they just plain work, although sometimes the pin in the puller is a little tight and it's hard to fix.
with a couple exceptions, the others are mostly junk, and like Marty says, they're not serious tools and usually do as much damage as good.
so i guess i''d recommend the separate tools first and then the high-maintenance italian actress when you can afford her.

I've been using the Ninco cheapo for 3 years with no problems. Only got frustrated with it for the first time recently when working with the motor from Daytona Coupe. Darned motor shaft. Too long when on the motor. No way to accommodate it without the motor. Gave in and put the plastic pinion back on held in place with a little super glue.

Would love to be able to invest in a decent puller/press. But just can't justify the outlay. Heck... I've not even bought cars lately. The bulk orders of tyres have been sourced for someone else.

I know some of the Aussie guys swear by the MB Slot tool. But that's even more exxy than the Slot.it.

It sounds rather like Maurizio has got it right again with his offering.

For years I used a Parma puller and a bench vice as a press.....These worked but I did wreck a few pinions and some motors in that time....I called it learning.

Now days I use the Hudy puller and press.

I saw a previous post mentioning the problem of a pinion too close to the endbell or can bearing for even the slim jaws of the Hudy.
I solve this by crushing the pinion with sidecutters or linesmans pliers...........What?.... my name munter !!

The danger with a poorly designed press is that the motor or the screw will get a little sideways and the motor shaft will get bent. A number of the presses that I have seen have a small diameter screw that is not machined properly. About twenty years ago it was snowing when I got up one morning and I called work to see what was up. A recording said that it would be a regular work day, but when I got there the security guard said that work had been cancelled. Instead of going straight home I spent some time in the machine shop making this press. It was designed for 1/24th motors, but it also works great with 1/32nd motors.

Just an observation . . . .

Most of the gear pullers utilize a design where the pin is rotating while pulling the gear off. However the design also locks the gear in a stationary position so there is friction between the pin that provides the force necessary to remove the gear and the motor shaft.

Many of the gear presses use a similar design - rotating surface against stationary surface - when pressing the gear on.

I did see that Mrslotcar also offers a 1.5mm pin for their puller as well as the regular 2mm version.

I guess I'm in the minority here. I haven't used a press or puller for several years now. I used to use them a lot until I started drag racing, and I was informed that I shouldn't press them on anymore as it distorts the gear just a minute amount. I thought why would it do that? So I was shown what happens when you press them on. Uncle Frank as we called him went on to demonstrate. He bought 2 press on pinions. One pinion he pressed on, then measured with a digital micrometer it was sort of an oval shape out about .002- .003. The other pinion he took a 2mm reamer and reamed it out and soldered it on, it was only out about .0003- .0004. He said pressing them on makes it difficult to keep them round as that metal has to go somewhere and it causes friction. Friction in turn slows the car down. These were 64 pitch gears, but helps other pitches too. So I always solder on my metal gears. :)

I have used a Ninco for about 4 years without to much drama I read what FootScoot wrote & that seems to complicated for me so I will still use the Ninco nice & simple

If i could find a 2mm reamer! Locally.

Took me long enough to find a set of 2mm taps.

I believe Sloting Plus are the only one doing pinions with set screws at the moment.

But, if you're worried about the poofteenth of distortion from pressing a pinion on, surely you'd also be concerned about the imbalance caused by drilling a hole and filling it with a screw of a different metal.
