A quick, foolproof method of removing these two blind bearing races from the housing.

 

Simply run a bead of weld all the way around the inside of the race. As it cools it will contract and the bearing races can be lifted out.

 

Done.

I really don't like being a party pooper, but it's not a good idea.

 

It can (and usually does) distort the Cover. The Bearing Ring may feel like it goes in OK, but it may not be round, though, the worst of it is, as it's right on the edge of the Flywheel Housing (on the other side), it usually cocks over a little and so is no longer square in line.

 

The factory also caution against this too;-

 

One type of tool that's fairly popular and quite inexpensive to do this job with is a Collet or Internal puller. Most work with a Slide Hammer.

DON'T use the type with a collet expanded by a bolt that passes through it and presses on the bottom of the cover because it can split the bottom away from the cover  (which then needs fixing with Plastic Padding)

Hmmmm, the jury is out on this one as far as distortion is concerned.

 

The ally casting is so large the heat will just leach away. 

As far as the 1st motion shaft is concerned, there is a fair amount of slop in the nose roller bearing so I'm not overly worried there. Installing a new race isn't a guarantee of squareness, regardless of extraction method. i'm running roller bearing drop gears so the needle bearing isn't an issue.
