blaze Posted November 3, 2007 Share Posted November 3, 2007 Rebuilding a 2.5 DOHC Outback 1998, It has 197000 miles on it. Bought new OEM Main and Rod Bearings from the dealer. Rod bearings are way smaller in size and are going back. The Main bearings have a different part number on the back? The old ones read S8BK X4, the new ones are S6CI E4? Are these the same size? Did a Plastigage oil clearance test, and it reads .002, this is out of specs. Book states .0016 is max. Normal is .0004 - .0012 . Haven't miked the crank yet, I'm sure its worn down, if these are the correct bearings. Part number on the box is correct for standard size 12209AA200. Can anyone explain the numbers on the back of the bearings? Quote Link to comment Share on other sites More sharing options...

blaze Posted November 4, 2007 Author Share Posted November 4, 2007 Thanks a million, I was hoping they made a mistake with the main bearings as they did with the rod bearigs Does anyone know the correct part number for the rod bearings? The ones they gave me (12108AA530) are for another engine, maybe 2.2? Thanx again for the info, you guys rock OH YEA, mine was built in 4/98.

blaze Posted November 4, 2007 Author Share Posted November 4, 2007 Must be wrong part (rod bearings) in box? Because these are about 3/8 inch shorter? And 1/16 inch narrower:-\ Thanx Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted November 5, 2007 Share Posted November 5, 2007 Hm..not sure. Maybe since your '98 is a relatively late build they switched to the '99 parts; not sure? 12108AA290 BEARING SET FOR CONNECTING ROD FOR 1999 LEGACY OUTBACK & SUS 2.5 Quote Link to comment Share on other sites More sharing options...
