PINESMOKER Posted January 23, 2013 Share Posted January 23, 2013 I'm about to start a timing belt replacement. I see every one and there mother has commented on the crank shaft marks. On how not to use the arrow but use the notch on the back half of the crank. Can anyone point me in the right direction of what marks am I lining up. I know the cam marks to I to the top and match the II marks to the cam above it. Need a little help. 96 DOHC 2.5 Legacy Link to comment Share on other sites More sharing options...

PINESMOKER Posted January 23, 2013 Author Share Posted January 23, 2013 Found it..... The arrow on the crankshaft pulley goes to a 90 degree. Time off the the second mark. In the back off the crankshaft gear. Link to comment Share on other sites More sharing options...
johnegg Posted January 23, 2013 Share Posted January 23, 2013 crankshaft keyway goes straight down. Link to comment Share on other sites More sharing options...
dark_thorns Posted January 23, 2013 Share Posted January 23, 2013 don't do what i did and try to clamp down the driver side cam sprockets. apparently plastic likes to snap. -.- Link to comment Share on other sites More sharing options...
carltech2000 Posted November 17, 2016 Share Posted November 17, 2016 Please excuse if this has been covered, I certainly have read numerous posts. I've had the crank woodruff shear in my 96 ej25 dohc. the crank has spun inside the cog leaving the rest of the cam pulleys in time. I have reassembled it with a new key and do not have compression on the left side. is it possible that I have the crank 360 off? Or is definite valve collision? This motor I believe to be interference valve only. At no time did I have any collision noise or difficult hand turning before or after reassembly. Thoughts?

The crank spins twice for every 1 rotation of the cams. I always spin the motor over by hand after doing timing belts to make sure everything lines up after 2 rotations. If your valves were contacting, they'd most likely stop the motor from being able to turn over since the valves and pistons are trying to occupy the same space. I'd say pull the timing cover back off and see where the marks are. Link to comment Share on other sites More sharing options...
carltech2000 Posted November 18, 2016 Share Posted November 18, 2016 I did rotate by hand twice, everything lined back up, (very close) Conceivably, it seems it could be rotated 360 off and still line up. I'll pull today and rotate by hand again, but.... is there another indicator? I.E. Piston # ? Moving down or up? Link to comment Share on other sites More sharing options...
Brighton96 Posted November 18, 2016 Share Posted November 18, 2016 I don't know what the firing order is of the 2.5, you'd have to look that up and find the number 1 piston, it should be top dead center when all the marks line up. I doubt the valves are contacting the piston since most likely it would stop you from being to turn the motor over. When you turn it over the marks should be almost exactly on the timing marks, not perfectly on them but if they are off at all, that means it skipped a tooth.

doublechaz Posted November 18, 2016 Share Posted November 18, 2016 I thought the timing marks have all four pistons about half way in the bore so that valves wouldn't hit when that one cam jumps over from spring pressure while you have the belt off. That is the marks on the timing pulleys, not the mark in the rim of the accessory pulley that you use with a timing light. Link to comment Share on other sites More sharing options...
Brighton96 Posted November 18, 2016 Share Posted November 18, 2016 Now you got me wondering if I remembered right haha, when I did my head replacement a while back, the timing marks were all aligned and the #1 piston was at top dead. Maybe it's different for a non interference 2.2 vs dohc 2.5? Link to comment Share on other sites More sharing options...
livinon2wheels Posted February 24, 2018 Share Posted February 24, 2018 don't do what i did and try to clamp down the driver side cam sprockets. apparently plastic likes to snap. -.- the plastic is rather hard and brittle but you can get away with doing what I did...go to harbor freight and pick up two or three or more of the spring loaded welding clamps made from plastic...they are strong enough to hold the belt in place while you get everything lined up like it should be, and wont break your pulleys...cheap and dirty and it works. They also like to pop off with little warning if you accidently bump them but, if you are careful u can make them work. Link to comment Share on other sites More sharing options...
