pressing them out took 350 kilos of pressure



pressing them in took just 200 kilos.



I used a "home made" tool, cant afford the MAZDA one.



here, some pics. (video at the end, sorry its in spanish)

I took Lynn E. Hanover advice and used red loctite.

Nice work..........

I grind off the indexing tab. Since there is nothing to index in the rotor bearing. Then you can push them in or out from either side if you like. The key is a straight start on the push. My pusher is sort of a puller. It has a flange to stop the push at the edge of the hole, and a deep center to keep the push square. The other key is a very stiff press. A less rigid press jerks and stops and jerks and stops. Makes awfull noises. When the push stops, it is more difficult to start moving again, so it sounds that much worse. One of the few places where having way more power than you need actually works better.

a straight push is imprtant, i bent a main bearing last time....

good advice guys



I still need to press out the old eshaft bearings and press in the new ones



Lynn, I took your advice and used red loctite https://www.nopistons.com/forums/pub...#>/biggrin.gif

the dimensions of that tool to press out and in the bearing would be nice for users like my self so pretty please , dimensions of tools so i can try to make one my self

nice work man.



what's going on with your ITB project?

bringing this back from the grave



I was unable to continue work on the 7



I moved, my grandma died, I had to work 12 hours a day...



This january (probably) I will continue working on it.

I know this is an old thread but I wanted to share the tool I made for installing and removing bearings. I came up with a 2 piece tool design for installing and removing bearings that makes sure the bearing goes in straight every time. I have attached a couple of pics of the tool for installing the bearings in the gears, but the tool for installing rotor bearings is the same concept except larger of course and I made this one out of steel to make sure the concept would work before I make them out of brass.



Bearing Removal

Index the stepped end of part 2 in the bearing and press the bearing out.



Bearing Installation

Place the bearing onto part 1 with the tab towards the flanged end of part 1.

Bolt part 2 to part 1 as shown in the second photo.

Slide part 2 into the gear and line up the tab on the bearing with the notch in the gear.

Press the bearing in.



I have used these tools for several engine builds and they make for a perfect bearing installation every time.

nice tool!



looks like mine but a hell lot better made

Is there any interest in the tools I had made? If so I will post them in the market place. Steel is the cheapest material to use but I can have them made of aluminum or brass. What do you guys think?
