Spigot bearing removal by "Hydraulic" pressure

This is easy if you have a vernier and a lathe to make a shaft to fit up the inside of the spigot bearing.

I used a bolt that was lying around that was the same diameter. As shown in the pics.

'''Step 1.'''

Pump or fill the inside with grease until it starts to ooze out (as shown in pic)

You want to replace all the air inside the cavity with grease, the air compresses and will not work if you don't.

'''Step 2.'''

Put your bolt/shaft in down the centre of the spigot bearing holding it with something that's not your fragile fingers, then hit it with a hammer. 

The shaft will pressurize the grease behind the bearing pushing it forward, repeat this if you don't get it the first go.

That's the Bush/Bearing on the bolt.
It took me 2 goes to get it out.

=Dynabolt Method=

k guys, recently I did a manual conversion and I got stuck on the spigot bush.  There is no specific way to get it out and the tech info leaves a lot to be desired.  I tried drilling holes n smashing stuff but it never happened.  Then next morning I see a dynabolt lying on the floor, and I'm like 'goddam'.

So off to bunnings to buy the biggest one there, and a big washer to go on.  See pic below.

So I go home, put the washer on, and hammer it in (it's a tight fit).  Then I tighten it like a mother fucker and get two extension bars from a socket set and use it like a slide hammer, and BAM! it works.

==With a weight==

This is a extension on the dyna-bolt method for removing the auto spigot bearing, which is required for a auto-manual conversion. I believe the dynabolt method usually uses a chisel to provide the the grunt, I've found this way a lot quicker, easier and more successful.

===What you'll need===

#M20 dyna-bolt, as long as possible $4
#Hammer $you should have one already
#A weight off a barbell/dumbbell, I used a 10kg (needs to have the 1/2" hole in the middle)


===Procedure===

*Hammer the dynabolt into the bearing until about 1cm of the sleeve is inside the bearing.  The M20 should be fairly snug in there.

*Once that's in, tighten the dynabolt so that the head is drawn into the sleeve, the tighter you can do it = the better the grip.

*Once you're satisfied it's in there tight, remove the nut on the end, slide the weight on, replace the nut.

*Use the weight like a slide hammer and presto!!! she's out!
