As stated. I tried to remove the pilot bearing and couldn't get it out so now the oil seal is mangled and now I have no choice but to replace it. Tips and info on how to get the thing out of there would be appreciated. Is there a tool somewhere I could buy? I thought I seen one years ago,

Thanks in advance guys

 

A proper bearing removal tool is the best, I use a Mazda pilot bearing puller, I’m sure you can get one from NAPA or other stores that offer tools out for do it yourself repair.

 

Alright, I look into what they have available. I'm going to mazda on Friday to order a rear main oil seal so while im there ill ask about the puller nd go from there. Thanks!

 

The Mazda puller is very expensive....try to borrow one

 

Brutal. Maybe in some sort of miracle the dealership does infact have one that I could borrow or rent. I was thinking maybe I should of just left it alone but since I have it all apart now, regardless of what shape it WAS in, I should just replace it anyways.

 

grinding a groove on the standard ones helps, but definitely worth getting this

Pilot Bearing & Dowel Pin Installer & Remover...

$ 155 better than mazdas $ 480

 

I have the Mazdatrix Pilot bearing removal tool and the installation tool.
(I actually have a lot of rotary specialty tools.. we need to fend for our selves out here.)

Not sure where in NS you are located.

 

I guess ill see what mazda has and if nothing then ill have to buy one. the one for 155 seems half decent. much better then 480!!

And also im currently living in regina, sask. I'm still resorting to building all my own tools lol

 

I just grind a groove with my Dremel and it pops right out. A little chisel is sometimes needed if you don't go all the way through. Just did one yesterday.

 

Where exactly are you grinding this groove at?

 

I just grind from front to back after I take all the needle bearings and retaining cage out. It is hardened so get a good bit. That relieves the tension on it. Kind of a backyard mechanic way to do it but for the few times I have had to do it, I couldn't justify the money on the tool. To install I have used a socket before and a bearing installer my buddy has. Both work.

 

I did exactly the same thing!
I couldn't get a puller in town and the guys were saying "Partsource in Ottawa" as some of the worked there.
I go to Ottawa and grab the puller,drive back 70km and find out the damn thing was worn beyond use.,..Ah FUDGE!..so Get out the Trusty Dremel,knock the cage and needle bearings out,use the 1/8 bit that you can cut stuff with and made a line up and down the length of the pilot bearing.You hit the Edge of it(between the E-shaft and the bearing) and it will "fold in on itself".Then you just use a set of needle nose and Pull.

 

Regina? Well, you have a whole other set of problems we can't help you with...

 

So basically ill just mangle the ole girl and rip it out lol sounds legit!

And also yes, I came here for a 3 month shut down here in regina and they trapped me into stayin for now over 3 years ! ahahha oh well, its all good

 

Shove bread in it and use a socket or a clutch alignment tool to keep packing it in. Pack enough bread in and it will come out

 

If you get the Mazda tool it makes the job take 30 seconds.

I got mine from a member online, one of the best investments for rotary related tools if you can get it used from someone.

I think I paid $70 for the puller and installer.

 

The tool is quickest and easiest but if that isn't an option, This method worked for me to get mine out. Cost was free and it helped to have my engine sitting on the table when I did it

I bought a standard and cheap universal puller like mazda's but not a sliding hammer type, ground down the INSIDE on the 3 'arms' so they woukd fit into the hole, and sharpened the 'grabbing edge' and turned ot out...

Link to tool I modified a tiny bit too work

Awesome! Thanks guys, I'll have a look at these tools. I think it would be wise for me to buy one since I can see myself needing it again and again.

 

Follow up- I bought the universal bearing puller from Princess Auto. I modified it a bit like I was told and it worked pretty decent. I ground down what I needed to make it fit inside the hole and sharpened the "hooks" on the end. Cheap and easy.



The new pilot bearing is now in but I realized that in all of the oil seals I bought I didn't get one for the pilot bearing area. I'll give Mazda another call and get that ordered.

But... while trying to install the new flywheel I had trouble with the little lock key on the eccentric shaft. It was pitted somehow so I tried lightly sanding it down too smooth out the surface. tried it again but the edge caught whatever was left of the pit and made a nasty notch in the lock key. SO, ahaha any tricks and tips on this one? Should I buy a new lock key and try again? It's been about 6 years since I last did a flywheel swap and I just cant remember at all what I did to make it all go together so smoothly.

 

Bump, still looking for info on reinstallation of flywheel. Thanks guys

 

I'd just replace the key. With the "nasty notch" as stated it is more likely to fail (not saying it will). But for what is probably $5 from the dealer, why not replace it.
