crank pulley shifted???

01 2zz. following TSB to do lift bolts (removing cams, pushing out rocker shafts).

rechecked timing before reinstalling chain tensioner and noticed that crank pulley was no longer at 0 for top dead center, now closer to like 7. however cams are at top dead center and all my timing marks line up.

is something wrong here? how could it have moved? DO I NEED TO REMOVE CAMS AND SET CRANK TO 0 AGAIN?

UPDATE: i relaxed a little and think i found my solution.

gonna pull exhaust cam back out to allow enough slack in the chain to separate it from the intake cam too so that the chain is only on the crank sprocket. i’ll turn the crank pulley back to 0 while someone holds the chain, making sure it doesn’t slip.

the only thing moving should be the crank.

once the crank is back at 0, i will reinstall the exhaust cam and set the chain back on the cams. everything will be connected again. then i’ll have to check timing by checking crank pulley, cam position, marks on cam, and # of links between cams.

make sense or no?

is there any better way to realign cams and crank after they have moved independently of each other, besides tearing the engine apart?

Make sure that your crank pulley is lined up and set the cam shafts as close as possible to their marks, try to get someone to help you turn the cam shafts while you put the chain on! As long as there's no slack in the chain on the intake cam side and the links in the chain match the sprockets, when you pop the tensioner on, it should be ok! I'll try to get my old pictures on here if it helps!

Just get the all the marks lined up, then you can angle the camshafts downwards to slip them in or you can take off the exhaust side sprocket, finagle it in, then bolt it on.

Good luck
