They are 5mm thread I believe, good luck on your search...

very common - hobby shop likely has em

Does anyone know of a cost effective way to reverse a motor shaft. The drill presses and other tools are too expensive. There has to be a safe way to do this without spending hundreds of dollars on these large tools. By the way, I went to my LHS in Indianapolis today and asked the air department guys if they could repair a couple of my spare motors that are having issues, and they don't offer that service. I have an Eflite parkzone 450 that is making a rattling nose...(sounds like a ball bearing problem???) I can hear the noise when I shake the motor. Anyone have a good tutorial to fix this problem???

Thanks,

John

John,

If you can't afford the tools then don't buy motors you need to modify. You need some way of pressing the shaft and banging on the shaft with a hammer is not going to work.

For the Eflite motor problem call Horizon Customer support and ask if they can warrant of repair the motor. Often they will say send it in and give you a replacement.

Buy a vise , if you dont have one you should have , big enough to take the motor and a piece of tubing to take the lenght of shaft...easy

Prof,

I'm not sure that price is the real issue here. I went to Lowes today and the drill presses are a couple hundred bucks. I also went to the hardware store and didn't see anything that would do the job. I obviously want to do it right and if you have any ideas of what type of press I need or where I can shop for one let me know.

No worries! I feel dumb for not "getting it"

I already told you......get a vise...you gotta take my ADvise and ADD a vise

I don't see how a U-shaped Vise will work, but I will give it a try. What do you mean by "piece of tubing to take the lenght of shaft". I do understand the concept, but need to see how this would work. The vise would need to exert uniform pressure to move the motor shaft to the opposite side, so how do you not bend the shaft? I do appreciate the help.

It's not a 100% way but I take big nuts on the side where the shaft is supposed to go and try to put the motor at the right angle into the vise. Then press until the nut's end is reached and insert another nut. Usually it works. The nut plus the motor side give me enough alignement to get it straight.

You'll figure it out...........I think...

I still do the maintenance on both of my cars and that includes changing the distributor when necessary (includes setting the timing), adjusting the valves etc.

Oops, that's what I did... I removed the bell and put it on a hard and flat surface with a hole in it. And then carefully knocked it through.

Motor runs very well, but probably it helps that it's a 5 mm shaft.

A good C clamp can be modified to do small electric motor work. We started using em on slot car motors (pressing gears) many years ago
you need a GOOD C clamp- and you will have to make a hole or dish in one end for centering the shaft
uing CA and putting a small drilled block , centered on one end will work

I cannot find the distributor on my Honda Odyssey or my MB 300 turbo diesel.
When I was a boy, I could see .018 easily- No need for feeler strips setting ignitions
