Hi Again Cole!
Does anyone have a layout or diagram of how the engine is put together on
an 82 Subaru GL-10 with the 1.8L Front wheel drive engine?
It can be trying to fit one back together, especially if you didn't
see it come apart; the factory manual devotes an entire section to
dis/reassembly of the engine, it's not trivial.
If you are just doin' it for grins, fine business; if you primary goal
to get the car to run, I'd highly recommend finding an _intact_ EA-81
motor somewhere, and using that. All are basically the same, but there
may be differences in the intake manifold and exhaust/air suction
valve configuration. These differences are relatively easily dealt
with by swapping parts around.
That said, here is a brief procedure for the engine:
Everything should be spotless. Unless the parts are clearly labeled as
to where they came from, you will need to gauge every bearing set to
insure proper clearance.
Assemble rods to crank.
Set the case half with the tapped holes on bench. Install beaning
halfs, crank, cam, and seals. Install sealer, set other case half in
place (should be a couple "locator" pins), install case bolts, and
tork appropriately. One of the bolts requires a cap to be fitted as
well.
Install pistons, and fit wrist pin and clip thru access holes. Install
plugs.
Assemble cam gears, set valve timing, and locking tabs. Install rear
case.
Install lifters (a few had hydraulic lifters; most were solid, may say
on valve cover), and push-rods. Assemble heads, and install. Set valve
clearance.
Install oil pan, oil pump, water pump, intake manifold, alternator/AC
brackets, oil fill tube, alla the rest of the brackets, engine wiring,
and carb.
Install flywheel (use sealant on bolts), and clutch parts. Coolant is
routed thru the intake manifold to the base of the carb; be sure to
hook this up. Also, don't forget the EGR pipe.
I'm sure there are at least a dozen things I've omitted; having access
to the factory manual will be helpful, but again, if you didn't see it
come apart, you will likely experience several false starts before you
get it right. (True even if you _did_ take it apart in my experience
;-)
ByeBye! S.
