cal_look_zero Posted October 31, 2012 Share Posted October 31, 2012 18" of 1/4" round bar from a steel shop. Pull the outer (accessible) retaining clips and insert the rod from the backside. Tap it out with a hammer. Very easy. Link to comment Share on other sites More sharing options...
Brat78 Posted October 31, 2012 Share Posted October 31, 2012 I bought a slide hammer set from harbor freight for about $70 when I tore my ea71 down. I don't see the exact set online anymore but they still show some. Made the job real easy. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted October 31, 2012 Share Posted October 31, 2012 I always wondered how that would work, any pics around of this process. I never wrenched that deep on a soob engine - yet. Link to comment Share on other sites More sharing options...
davebugs Posted October 31, 2012 Share Posted October 31, 2012 I used a round prybar from a cheap set that was tapered at the end. But I also took a chunk out of most of the pistons on that blind side. I was scrapping the engines anyways. But it wasn't the best method. Perhaps the flat end makes a significant difference.

Gloyale Posted October 31, 2012 Share Posted October 31, 2012 Pull all the wrist pin plugs. remove the outer clips. Now look all the way thoughthe holes in the block....see something.....the holes go all the way through both cylinders! If you are careful, you can squeeze a dowel or punch past the rod of the "up" piston, and tap the backside of the pin on the "down" piston and just knock it straight out. Rotate and repeat from the other side for hte other piston. Use a long dowel or punch.....but it needs to be skinny......not much thicker than a pencil. it takes a touch of angle, so make sure you aren't gonna wedge it in. Wooden dowels are great for this and cheap from the hardware store. I used to use a slidehammer and a hooked bar......still do for EA's But with EJ's it's just easier to knock em straight out through the opposite hole.

ShawnW Posted October 31, 2012 Share Posted October 31, 2012 Yep. And its not possible to knock them out that way on an EA or ER engine. Link to comment Share on other sites More sharing options...
Subruise Posted October 31, 2012 Share Posted October 31, 2012 i took a j bolt from a battery tie-down and used a vise to squish the hook until i could force it through the hole. i then threaded two nuts and a washer in a sandwich at the other end. clamp vise grips up there and smack with a hammeer. start out tapping and increase kinetic transfer until wrist pin comes out. it wasnt easy, and i couldnt re use the j bolt but ive made a few of these and pulled a bunch of pistons. i now strap my battery in with a ratcheting tie down:D Link to comment Share on other sites More sharing options...
Ricearu Posted November 1, 2012 Share Posted November 1, 2012 I took a thin rod from an of curtain rod and bent it just a smidge. Worked great on two ej's so far. It has a permanent home in my tool box now. Link to comment Share on other sites More sharing options...
