Removing piston gudgeon pin

[Ryan]

Any ideas on how to pull out the piston gudgeon pins when they are in the block without the OEM Subaru tool?

Tis easy..

Don't pull but rather push it out.

If you try to remove the pin from piston 4 do it by pushing through the gudgeon pin access hole for piston no 2.

Do this by positioning piston 2 such that it is just before or just after TDC and you can see no 4 gudgeon pin through the no 2 hole.

Use a long thin flathead screw driver, butt it up against the gudgeon pin and gently tap it out.

Be careful that the no 4 pin dosen't catch on the top of the no 4 access hole as it slides out - this will happen if you are too far from TDC on no 2.

No 2 will be easy to remove now doing the same thing just starting from no 4 access hole - con rod will not be in the way this time.

Repeat for other side.

And pre-empting another question of removing pistons...

Once the pin is out rotate crank a full revolution.

Both piston 2 and 4 will be at TDC.

Push no 4 down the bore and rotate it a minimum of 45 degrees at the same time.

Then do another full rotation of the crank - rod will push the piston out.

Another way is with a large flat head nail. File the lip a bit thinner and then slide it down the inside of the pin, while holding it with vice grips. It can then be pulled out easily
