Can you guys / gals tell me what size allen wrench is used to remove the plug that facilitates piston pin removal? Can you think of any other special tools I need for engine tear-down / building that are Suby-specific? Thanks in adavance!

Thanks anyway folks....it's a 14mm:)

Hey, it's a 14mm. :D

And the cam gears are 10mm.

The really tricky part is getting the *&%$@#*& wrist pin out if you don't have the Subaru tool!

Yeah, I thought about that..how'd you guys do it? I'm thinking of machining a tool steel insert and using vacuum (?)...I dunno:) or... (a novel concept) buy the tool from my local dealer. ($$$)

14mm hex socket, not to be found anywhere. Not Napa, Sears, local hardware, Pepboys, Autozone, Lowes....

Sounds pretty interesting. If you get it done please post how you did it thanks.......

It can be done with a really long screwdriver and a friend holding a flashlight. :D

I'm not saying it will be easily, just that it is indeed possible. :huh:

i bought mine at autozone it cost 11 dollars after tax came in a set of 3... 12mm 14mm and 17mm

just to follow up on this, take a 14mm bolt and put 2 nuts on the other end to lock them together. stick the head of the bolt into the hex you're trying to remove and put a wrench on the inside of the two nuts and crank on it. if the nuts are locked together it'll work perfect.

That's quality.

After you do that you need to remove the piston pin

You need the special tool 499097700

How do I get the tool or use of one?

So far this is what I've found

Click (http://subaru.spx.com/index.asp)

easiest way to get the wrist pin out is with a 2 foot (or around that length) very thin screw driver. If you wanted to take out the driver front pin, you will stand behind the driver rear pin. Rotate crank until the driver front pin is in front of its access cover. Slide thin screw driver in and rest it on the back of the wrist pin. Lightly tap it until it comes out.

like turboL said or take 1/4" steel/chromoly rod heat the tip up an smash it flat...then keep hot and put tip in the vice and bend a crook at the tip for grapping the backside o the wristpin...quench it when done

I like metal work :D

Other than using a long thin screwdriver, I have also used a simple wire hanger straighten out with last 1/4 inch bent at a 90 degree angle. Just hook the far edge of the wrist pin and pull. This will only work if the pin has not pounded the circlip distorting the piston pin bore. If that has happened it will take some force to get it out.

what i have done in the past is you take two 16 penny nails... framing nails... weld the points together so you have the nails in a straight line with the heads on the ends. (You might have to make the diameter of the head smaller on one nail.) Remove your access covers and the outer wristpin clips. Then insert the head of the nail that you grinded down a little bit until it pops out the other side of the wristpin. Then insert a screwdriver next to the nail so it is offset in the hole and the head will now grip onto the other side of the taper inside the wristpin.. then just pull it right out.. it actually works really well... beats buying a hundred dollar tool

I use a wire clothes hanger.

I used a piece of chain link fence wire, had to make 3 of them....they kept bending.

Whenever I do it again, I will buy a $3 screwdriver, heat the end up, and bend the last 1/8''-3/16'' 90 degrees over to make a hook.

Screw buying the $100 plus dollar tool, make your own.


EDIT: If you go to home depot or lowes, or whatever, try to find a small piece of wooden dowel, looks kind of like a closet coat rack "bar". (the part the hangers hang on) Take your EJ wrist pin with you, works like a charm for re-installing the pins. Sometimes the thumbs get sore.

try around $300
no kidding

just a long beak pliers suffices

For ST 499097700 :confused:

rotate the crank until the wrist pin of cyl#1 is in view and remove wrist pin. You may want to rotate it so the rod on cyl#3 is slightly above or below so you can insert a 1/4" rod through service hole #3. Taking the LONG 1/4" rod.....punch out the wrist pin of cyl#1 by running the rod through cyl#3's service hole. The END of your rod will come in contact with the wrist pin of cyl#1. You use a hammer and punch out the wrist pin of cyl#1. Do the oppisite with cyl#3 by inserting the rod through cyl#1's service hole.

all done and said. You're all welcome!

yeah....not too sure if I was just lucky or what. I used a set of needle nose pliers. Put it in the access hole and opened them, and the pins came right out...took 5 mins.

easiest way to go about it, seriously...Go to a local suby dealer with a maintenance department. just ask them to pop it for you. i messed around with mine for atleast 2 days before i said, "well suby mechanics have to have this tool" they opened a brand new wrist pin tool box, popped them out for me and i was on my way. being the nice guy i am i tipped them :banana:

Video I made. This is for ej22 and ej25 only though, because the WRX 2.0 has those funky pins....

i've used a long screwdriver, a socket, and some electrical tape. Slide the socket onto the screwdriver shaft and then wrap the screwdriver tip in electrical tape. Use enough tape so that you have to tap the taped end into the wrist pin. Now use the socket like a slide hammer by banging it against the handle of the screwdriver. Don't forget to take the retaining clip out of the piston.

cheap and works well with the factory wrist pins.

I ****ed around for an hour trying to make the special tools everyone suggested when I tore down my first subaru motor. Then I came across this method. It is so easy!

rotate the crank until the wrist pin of cyl#1 is in view and remove wrist pin. You may want to rotate it so the rod on cyl#3 is slightly above or below so you can insert a 1/4" rod through service hole #3.

To bring the thread back, I got myself a $30 tool today that works awesome.

It's a set of legs for a GM steering wheel puller, KD Tool part number is 3510

I had to grind about 1/8" off the end of it, but apart from that it slips right in, then you can use a prybar to jimmy the pin out. Took me about 90 seconds to pull each pin. I intend on modifying it a little more to include an attachment for a slide hammer
