Outer axle needle bearing removal and install

[The Tuul Crib 7,336]

 I tore down a three speed today and noticed that the outer needle bearings on the case we're toast. What is the best way to press these bearings out without beating them up.

I use a socket and extensions in the hydraulic press to remove and replace the bearings. One inch impact socket works great on 1 1/8" bearings.

The above method works great if you have needle bearings left in the bearing case.  I stick the extension in the reverse side of the socket because the back side of the socket is usually sharper and a better fit.  The socket can, if it is not a real good fit, slide by and get stuck.  A punch with a good square end a ball peen hammer always work when all else fails.  You do not need to beat it to death.

I dont have a press or access to a good one. I really didnt want to beat on em 

too much.

You do not need a press.  You can just tap on the extension and socket, or work your way around the bearing case with a punch.  You do not have take full swings.
