Has anyone used SKF 4913 as a replacement for the OEM part 65019?

I really hate crank seal installation. I really haven’t figured out the trick yet....,I have changed the seals on two saws now and it’s been a disaster each time.

What happens?

I have destroyed 2 seals before I get one driven straight. I find that I just can’t get them to go in flat. Usually one side will drop in lower and then the other side will bind up on the casting which will bend it out of shape.
Tried using a 12mm socket on the mini.

I use a large flat washer under the socket so I can watch if it's going straight.
Patience is the trick. Just go slow and build up any steps in the crankshaft you have to go over on the clutch side.

Don't feel bad, I've wrecked a few myself. Sometimes it doesn't matter how careful you are. But Fossil's washer trick is a good one; it helps ensure even pressure to help drive it straight.

If a seal starts crooked it will be very hard to straighten it by driving it further. Take it out and start again. Use light gentle taps, like fossil said, "patience" is a virtue.

Patience is virtue and swearing makes it more bearable!

I found that throwing the bent and destroyed seals against the wall while swearing helps a little as well! Unfortunately it did not alter the outcome whatsoever.....

You need to hold your tongue right as well.

Well....more lessons learned from the school of hard knocks. I swear I’m cursed to never use a Super Mini. Long road to get this thing to the point that it would even cut some wood. Know it’s back to the bench. Oh boy. I really should fire my mechanic! I have found that I’m talking to myself more than usual lately so thought I’d record some of my misadventures. Here’s a test run.....and failure. Started out ok....ended not so good. youtu.be/WwviLSydX9M

You have luck like I do.I'll work on a saw,sometimes for days,then when I think it's all set to go it craps on me just like that.Very discouraging.

Nice work. MUCH better than a rod cap problem, eh?

Yup. Much better fer sure. I literally just put the thing back together. Last thing I want to do is tear it apart again. This was supposed to be an easy runner (I hoped).
I destroyed the crank shaft while removing the flywheel for a general clean up of the saw after it arrived at my house. Never imagined you could do that kind of damage to the end of a crank shaft while using a puller. Flywheel was stuck good. Completely destroyed the end of the shaft. That lead to a complete tear down. Luckily I had a parts saw on hand.
Always a few surprises with an old saw I suppose. Who knows his long it’s been sitting or what someone else has done with it.
And to be honest I’m a novice at best when it comes to small engines!

For someone who's just a novice,I think you did a helluva job!

I guess I’m living proof that you can learn to do anything if you really want to try and learn and aren’t afraid to fail a bit. Lots of helpful information and people on this forum as well.

Finally got this saw figured out...,,,I think! I’ll run it in some wood tomorrow to confirm. This one has been a real challenge! Got the seals in thanks to the advice of fossil an Sweepleader and others. Thanks for the tips. It’s sealed up perfect and passes the tip test now.
I thought that I had fuel system problems for sure. Turns out that the prestolite coil was the problem. It would fire and run as seen in the video....then die out like it was running out of fuel or flooding. After tearing the carburetor apart a few times and changing fuel filters a couple of times nothing seemed to make any difference.
Today it finally stopped starting at all. I thought I had a bad plug. Changed it and still no fire. Aha! You dang blue coil of death! Gotcha.
Swapped it out for a known good one and sure enough she fires and runs smooth.
I really thought that a coil would just die and not work at all. I never imagined that they would just progressively die out.
What a saw! Definitely a challenge. Started out as a good looking cheap EBay saw that needed a clean up to a total tease down to the crank and rebuild then a wild goose chase due to Prestolite blues. Booooo Prestolite!

Celebrated too soon. Ran for a couple cuts. Couldn’t get it to tune properly and then it just died and no fire now.
Question;
Are the flywheel keys different on a points ignition system vs an electronic ignition?
I put a crank shaft from a points saw in this one when I put it together but kept the electronic flywheel and coil.....
