zackdeha Posted January 22, 2009 Share Posted January 22, 2009 Hi im here looking for help. i am in an intro to power mechanics class and im rebuilding a subaru engine the only identifying number i could find was EA71. im looking for any kind of information possible about this motor. i dont know what year or model it came out of. i figure if i can read up on it as much as possible than i can dissassemble and rebuild it efficiantly. for the assignment it is not required to run when its reassembled but to me that defeats the purpose. but any information will help thanks Link to comment Share on other sites More sharing options...
the sucker king Posted January 22, 2009 Share Posted January 22, 2009 the basics are that it is a 16oo cc horizontally opposed, water cooled, pushrod 4 cylinder. You can get the factory service manual on ebay for under $20 usually and that will walk you through dismantling it and reassembling it. They are pretty simple engines. You will have the time of your life. Also gasket kits are available on ebay, which you will want if you really want the engine to run. Have fun!

subystomper Posted January 22, 2009 Share Posted January 22, 2009 Subaru used that motor it all their 70's and up to 81 Wagons, cars, and Brats both 2 and 4 wheel drives. Hope that helps. Good luck with it, John Link to comment Share on other sites More sharing options...
zackdeha Posted January 23, 2009 Author Share Posted January 23, 2009 hey thanks guys.... its weird just knowing what cars it was used in and the basics helps make it feel more comfortable while working on it. ill definately invest on the shop manual tho for all the specs and timing.

mcbrat Posted January 23, 2009 Share Posted January 23, 2009 you could get them up through the mid 80's actually... we could tell an age range from the bell housing and starter position (top center, or drivers side upper) also, are there any stickers on the valve covers signifying whether or not it has hydraulic lifters....? is the EA71 stamp on the front part of the block by the disty, or the rear of the block by the oil fill tube?

moosens Posted January 23, 2009 Share Posted January 23, 2009 There are 2 versions of the EA71 - keep that in mind always. Great engine,either one. 1st verse - called narrow case , has top starter all years. 2nd verse - called wide case or fat case , has top starter in early years ('79-81) You'll find the starter at driver's side upper begining around 1980 thru any 1600 for the USA onward - 1987?? or so. Chorus - like Sucker King said you'll have a great time. Personal opinion from many is that these were the best for reliability and simplicity. Enjoy! If you're not in a hurry wait on eBay and a factory manual will come around for $5 or so. Otherwise $20 ain't so bad either. Link to comment Share on other sites More sharing options...
zackdeha Posted January 24, 2009 Author Share Posted January 24, 2009 there were no stickers indicating whether or not it is hydrolic lifters or not. last night i tore just about everything off of it so now it is just the case and heads. i want to wait till the service manual gets here or i know more about it before i try cracking it open..... i heard the pistons were the biggest pain in the arse to get out though? somehing about lining up perfectly? well anyway the stamp was in the front right on top towards the pully system Link to comment Share on other sites More sharing options...

The tool is like a puller with a slide hammer. Some guys on this board have made their own tools to get out of tracking down the real deal, with great success. perhaps somebody will post a pic of a homemade wrist pin puller? No hyrodrolic lifter stickers means it should have solid lifters. The significance of the location of the ea71 stamp is that the ones stamped on the front of the block are year 1980 and newer. Before that they were stamped on the block above the #4 cylinder. Also significant is the location of the starter mounting hole on the bellhousing. Is it Center top or more towards the drivers side? The latter has a larger flywheel and can be mounted to newer transmissions. Keep us posted, we are full of advice, or at least full of something....

zackdeha Posted January 26, 2009 Author Share Posted January 26, 2009 well today we took the heads off and that was about it. apparently my partner dosent want to be patient and take it slow, because she had the heads half way off before i was there and mixed all the parts up! no worries i sorted them out and figured out which rods and arms came from which side. im guessing she is gonna want to crack the case open on wensday so i guess if i could get some tips on battling the piston heads would be nice. from what i understand you have to pull the plug that is on the side of the case and undo a snap ring? thank you for helpin me out with some info by the way.

4x4_Welder Posted January 28, 2009 Share Posted January 28, 2009 (edited) My custom tools: And patience. Hook the nail in the back side of the pin, pull it towards you until the built up crud stops it, then tap it back in and pull again. Three or four tries and the pin is out. On edit: If you don't have a proper allen wrench for the plugs, then find a bolt head that fits, and weld it onto a socket. For the rears, the bellhousing comes off, and the holes for the pins are right there. Edited January 28, 2009 by 4x4_Welder Link to comment Share on other sites More sharing options...

bratman18 Posted February 2, 2009 Share Posted February 2, 2009 remove bellhousing and wrist pins read the manual I don't think he has the manual yet, he was waiting on it to show up. Link to comment Share on other sites More sharing options...
zackdeha Posted February 3, 2009 Author Share Posted February 3, 2009 i did remove the bellhousing and the wrist pins. i read the manual and it says to remove the bolts behind the gear connected to the cam shaft. then pull camshaft toward the back. but thats it. ive double checked over and over again if there were any bolts forgotten but we have gotten them all. it seems as tho the manual skips over the splitting the case step. its very vague for a service manual i would say. but ya i dont know what the deal is, figured maybe you guys have run into this problemo before Link to comment Share on other sites More sharing options...
the sucker king Posted February 3, 2009 Share Posted February 3, 2009 Make sure you have removed the bolt that held the oil pump feeder tube on the bottom of the crankcase. It joins the two halves. The case can be tuff to separate even once all bolts are out. Link to comment Share on other sites More sharing options...
the sucker king Posted February 3, 2009 Share Posted February 3, 2009 Actually I forgot, There is one other uber-hidden bolt. Look on the #1/#3 side of the block. In between the cylinders and just below them: see the recessed bolt? betcha that's it. Link to comment Share on other sites More sharing options...
