Hey Guys, putting the new EA71 in my car and I noticed the last person who had this tried to remove the spigot bearing from the end of the crank and has pulled the guts out of the bearing and left the shell stuck in there with nothing to pull on.  Does anyone have a trick to getting this sorted?  I'm thinking touching it tp with the die grinder and then tapping it with a punch to break it...  Surely someone has done this before?!

A common way with an intact bearing/bushing is to fill the center bore with grease, and then use a cylindrical object that fits tightly into the center bore to act as a piston, tapping it to force the grease to push out the bearing/bushing.  Heat might also be useful.

Depending how thick the shell is, you may be able to take a punch and carefully fold one side in until you have something to grab and pull it out.

Yeah, thanks guys.  I would normally have filled with grease and pushed it out that way, but some monkey who had it before me has butchered it and left the shell.  Will have another go this afternoon and see how I get on.  It's the last thing stopping me from putting the engine in!  On a side note, on the later EA71 that is internally cooled, can I just block off the single coolant line coming out of the block behind the dizzy?  I'm taking the manifold feed from the heater pipe on the nearside of motor...

Odd, I am in the exact same boat as we speak?!

 

 

Never thought of the grease idea.  I was gonna use a dremel and weaken the wall and see if I could get it to fold.

 

Post what you do.

Hahahaha!   Good to know I'm not the only one!  Exactly the same thing as mine!  Miles apart, yet having the same challenges.  Going to have a go tonight so will post up a few photos as soon as I have it out... or not.... :lol:  If all else fails I'll be on the power tools and big hammers!!!

In what sort of vehicle does your motor normally reside?

So fixed the issue OCD, attacked the remaining bearing case with a die grinder until I wore through in one place and then just tapped it with a thin flathead screwdriver and picked it out.  Problem solved.  Although what I didn't think about was that the bolt holes for the flywheel bolts go right through to the crank case and the was swarf coming off the grinder...  It all ended up in the end of the crank because the motor was leaning that way, but one can never be 100% sure that some didn't enter the crankcase through one of the bolt holes.  Oh dear.  Put it this way though, I'm not stripping the engine down and splitting the block to check.  Fingers crossed!!

Oh, and I forgot the camera in my excitement of rushing out to the garage to get it sorted...  My bad.

Ironically I got mine out last night as well, lol.

 

Used the Dremel as mentioned and had no issues.  Squirt some penetrating oil in there first to collect the grindings.  Then it popped out.  Easy as can be. New pilot and seal in and good to go.

 

My engine is out of a 1980 GL Brat.
