Snowman Posted January 24, 2004 Share Posted January 24, 2004 How do YOU remove piston pins when taking apart ea82s? I know subaru has a special tool that looks a lot like a slide hammer, but I couldn't find one, so a friend and I made a tool for it. We just took a large bolt about 5 inches long and ground down the head so that it could reach in and grab onto the pin from the other side. I then pryed up on the bolt and yanked the pins out. I am wondering if I should be worried about damaging the piston or pin by removing it in this fashion? How can I tell if it is damaged (i.e: what sort of scratches or marks should I look for?) Also, I read in the FSM that you need a product called ThreeBond 1215 to seal between the block halves and between the heads and cam cases. So far, I haven't been able to find this stuff. Subaru sells their special silicone sealer for this, but it's $40 for a little tube that would probably seal one or two engines if you're lucky. Where can I get ThreeBond? Is it even sold anymore? What else have people had good luck with as a substitute? My diesel professor suggested anaerobic silicone sealant, as it is used in the same way on Detroit Diesels. Anybody know if this stuff would work? Quote Link to comment Share on other sites More sharing options...
rallyruss Posted January 24, 2004 Share Posted January 24, 2004 anaerobic sealer comes in a lot of different types. what I would sugest is permatex ultra grey. it meets the import specs for sealant. I have had good luck with it. go easy applying it to the case halfs espically near the oil pump. and yes it is a type of anaerobic sealer. as for the piston pin tool. I made my own as well. you just dont want to scratch up the piston pin bore when removing the pin. The pins are really tough it would take a lot to damage them.

garner Posted January 24, 2004 Share Posted January 24, 2004 snowman my local parts guy tells me threebond 1215 is a Felpro product. I would assume it's 3-m product by the three portion of it's name. Ultra grey is good stuff I too made a wrist pin puller that I was quite proud of. I could post a picture if anyone would like to see it. Sounds like your deal worked just dandy. How about those clips? those are a pain Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 24, 2004 Share Posted January 24, 2004 I would love to see your piston pin pulller garner - I'm going to be doing this soon. GD Quote Link to comment Share on other sites More sharing options...
Snowman Posted January 24, 2004 Author Share Posted January 24, 2004 I'll try to post a pic of my "custom puller" too. I talked to another professor who has resealed a bunch of subaru motors in his day, and he recommended the same stuff that my other professor did. I can't remember exactly what it's called, but this stuff is red. He says after using that stuff the motors never leaked. So I think I'll use that.

toybuilder Posted January 24, 2004 Share Posted January 24, 2004 This is the one that I made: As for sealant, I also use the Permatex Ultra Grey. It was recommended to me by Rick at CCR Inc. Quote Link to comment Share on other sites More sharing options...
