Crank Position

Going through VADIS for the head reinstall, I noticed that there is a section about lining up the crank before installation. It says to remove this "blind cover" near the starter, then sticking this tool in there and rotating the crank counter-clockwise until it stops.

My question is, since I can't find the markings on the crank sprocket, can I stick like the end of a wrench in there to find the right timing spot? (The pulley mark does not line up with #1 10 deg BTDC)

Anyone else know anything about this?

so I am going this method...

1. what other tool besides the Volvo tool can I use to rotate the crank counter clockwise till it stops so that everything will be set correctly?

2. by rotating it counter-clockwise till it stops what is that? TDC? BDC? and is this what you do after you set the crank in there and lock in the rods and pistons before putting the head back on?

I used a large flat screw drive to spin the cams with the gears on till they were int he right spot then set the gears to the right spots

if your spining anything make sure you go half turn with the oppsiste so neither will contact the other when spinning the head or the bottom end since if you forget this is a interference engine , you shouldnt do any damage spining by hand but would rather be safe the sory

so when the head is off and the crank is all in with the rods and pistons and rings and torqued down... I insert a big flat head screw driver into the "blind cover" and turn the crank by hand counter clock-wise till it stops.... what is that TDC? and then I can move forward with installing the head?

:huh:

no I set the cams in place once everythign is set.

I use a 36mm nut and breaker bar to turn the crack

and use a long flat screw driver to set the cams.

not really sure what your asking ?

yeah, I am running on 4 hours of sleep and all my books are at home :(

I guess what is the point of inserting the tool into the blind cover and rotating the crank counter clockwise

It's just another way of lining up the crank before you install the lower portion of the head with the gasket to the block. It needs to end up at 10 deg BTDC (Before Top Dead Center)

I didn't do it this way though.

I just followed Justin's advice and found the crank markings. The same way as you would do a timing belt change. And since you have the engine out, it should be CAKE to find. What I did, was to rotate the crank to where i "thought" 10BTDC would be and looked in the teeth before and after the housing mark. Once you find the mark put the head gasket on and then carefully place the lower head. Lube your head bolts and hand tighten. Then go 20nm, and 60nm in order. Then the final 130 deg. Reinstall tappets (lifters) in their original spots.

Then you need to apply the liquid gasket to the upper section of the head, put the cams in and lock them in place. Then take that whole thing and lay it on top of the rest of the head. keep it all lined up as you tighten the 10mm bolts evenly. Its ok if they move a little, but try to keep them straight. After you have them all tightened, it just the last part of a timing belt job that is left.

Are you working on this now? I will have my write up done within a week, so let me know if you need pictars.

I will wait on doing this right now... some other parts need to come in for fitment :D

so basically you can use the counter-clockwise and Volvo tool method to get it at BTDC or I can line up the crank marks with this marking on the Oil Pump?

Yup. Make life easy and just line up the marks ;)
