I was completely disassembling my EJ22T engine and saw the Douglas Vincent thread on the home made piston pin removal tool. So I made one. And sat in my garage for 10 minutes pounding on it making no progress removing the pins at all.

I remembered reading something about knocking them out from the other side. So I looked through the access holes on the other side of the block and sure enough I could see the back side of the piston pins. I found a very small skinny metal rod in my garage and poked it all the way through the block and used my hammer to push the piston pins out from the back. Worked great! Easy as pie.

You will need the correct size phillips head screw driver. I used one of those punch drivers that you can put a socket on and I put a phillips bit in the socket and used that and a hammer to break the screws on the back of the engine loose that hold the two access covers on. They will be tough so you may need a punch driver.

You will also need a 14mm hex socket to remove the 3 plugs that cover the access holes to the cylinders.






Remove the covers and the plugs. Rotate the crank until the piston pins are lined up with the holes. Get a needle nose pliers (preferably a long skinny one) and remove the circlips that holt the piston pins in the piston. Then go to the opposite side of the block and looked into the access holes and you can see a small gap above or below the rod that you can fit a very skinny metal rod through to tap out the pins. Once the two pins from that side of the engine are out, turn the crank again until the other side lines up and repeat.

Easy as pie! Sure beats messin around with a homemade tool. I thought my tool was gonna work good too but those pins were stuck in there really hard.

Here i was thinking i was the man for thinking of this,i guess we're the man.

lol It wasn't my idea, I can't claim credit for it. I saw somebody (maybe it was you) talking about doing this in the wrist pin thread. They just never explained how they did it.

You could always buy the actual tool from 1stsubaruparts.com for like $144 or something.

Part number 499097500


My local dealership said they don't order tools for some reason. For $144 (probably more at the dealership than on that site, always is) you'd think they would be glad to order it. Probably make quite a bit of money off that tool.

I use both methods. My tool is the first choice, then I go the "backdoor" method.

maybe y got one of these layin' around
works like a charm for the punch
and then you can put 'er back when ur done :!!

Haha nice. Reminds me of using the turkey baster to remove your old fluids...don't put that one back when you're done. And don't let your gf/wife/mother catch you using her kitchen utensils in the garage!
