Camshaft timing marks

Both pistons are at the top of there stroke. Check the timing belt/chain it may be out of time there. Also, piston number should be at TDC when mark on crank is lined up, so it may be on number four. then recheck your work.

If its all okay check out this guide for why it wont start.

Please let us know what you find.

How do you know if the piston is on the exhaust or compression stroke?

They are one and the same once the piston is at the top it can be either.

How do i set the timing on the cams after removing the sprockets from the cams? Also, does number one cylinder have to be top dead center to get car in timing?

Replaced the head from a over heat.

Hello,

Yes the engine does need to be on TDC. Here is a diagram that shows the camshaft timing marks.


Please let me know if you need anything else to get the problem fixed.

Best, Ken

How do I line up the exhaust camshaft sproket to the camshaft? I removed the camshaft sproket while taking the valve cover off. There is no lineup pins on the camshaft. I just need to know how to line it up. It is a 2000 Volvo S40 1.9 Turbo.

Thanks!

Look on the teeth of the cam sprocket for grooves in the center of the teeth. Then there should be markings on the timing cover. Line these up on both sprockets.

The only way to do this is with a special tool. See picture.

Thanks for the answers everyone. mhpautos-after lining up the camshafts on the back do i then turn the exhaust sproket to line up with the front cover?

Problem is i do not know the position of the engine when you dismantled it. you cannot rotate the cams independently of the crank, if you do turn the cam you must do very carefully as to much pressure on a valve touching a piston will cause serious damage. do you know the relevant cam, crank positions before dis-assembly?

Mark (mhpautos)

need the camshaft marking setting that align with the crankshaft.

This is for 1.9 turbo.

How to line up the camshafts?

Did the belt brake or was it removed with out first aligning the timing marks? See picture for alignment points. if it broke you will have bent valves.

How do you do timing on a volvo s40 t4? the cam pulleys do not have marks.

we do not list a Volvo s40 in US, besides if it is ignition timing the computer does that.

There are special Volvo tools required to do this. see picture for a general view.

Want to know which valve opens in the exhaust when its timed, and also want to know which valve opens in the intake when its timed 2001 volvo s40 1.9L. camshaft, timing

The exhaust valve opens first then the intake. If you need to set up timing you will need buy the cam locking tool to set up the timing.

Need the align for the camshaft.

Here you go, hope information helps you.

When timing marks on cams and crankshaft aligns number two piston is on TDC. engine turns over but not starting. when putting number one piston on TDC and cams on mark then it locks against open valves and engine cannot turn over it just moves a bit. what angle and position must cam lobes be when on correct marks?

I do not show an S40 nor a 2.0 engine being sold in the US, so I cannot give you specific instructions. I know many Volvo's I have seen in the pasts require some special hold down tools and if you have already rotated it while out of time, you may already have valve damage.
Not all engines time on number one, many time on a position that has nothing on TDC to prevent valve damage.

When crankshaft sprocket is aligned on crankcase mark, should cylinders one and four be at TDC -or should cylinders one and three be at TDC? If neither, how many degrees + or TDC and on which pair? Engine came to me in pieces. Thank you, in advance for input.

Number one should be TDC.

I bought the tool for the back of the head for the cams, and I used whiteout on the camshaft sprockets b 4 I pulled it out, but, didn't whiteout the crank...the tool lines up the cams, but, the marks on the cam sprockets don't line up with the top cover...do I have to put in the crank tool so the whole thing lines up correctly? in accordance to the timing mark on the crank to the left of the ridge on the engine?

forget about the white out. you need to time the cams and crank and install the belt

Roy

hi i would to get the correct position of the timing marks of the timing belt. (all marks, e.g.: tdc and valves.

motor 1.6

Here are some diagrams and a page that shows you how to replace the timing belt and all the marks.

Attached is diagram

Sorry I believe, KHLOW has the proper diagrams for the 1.6L engine

hi i need to remove the belt (that is not a problem at all!) the problem is that we also need to remove the gears( were the belt moves, and then how do we know what is the correct position of the news ones?. Should be some diagram for that correct.? cheers

If the diagrams are not correct, they are similar. Before removing the belts, make sure you turn the crankshaft till you have the marks lined up accordingly.

After installation, manually turn the crankshaft 2 turns clockwise and recheck the marks. If they are off, it means you have not installed them correctly.

o the disgram is correct, but the geari mention is the crankshaft and the camshaft gears that i need to replace too... :(

Why do you need to replace the gears? If you have to, after removing the gears, reinstall them and turn them to the correct position for installing the belt. No difference.

There is no guide on the cams to install the gears if you remove them. You will need the cam lock tool to lock cams in place. If the cams are not in there correct position you could damage the valves because vehicle is not properly timed. You can look for the tool online but will run you somewhere between $300-$600 dollars. The tool will come with the cam and crank lock. f you are trying to remove the exhaust cvvt and intake cam gear for an oil leak then replace the cvvt hub also along with the seals. Those things always start to leak after 100k miles. I Hope these info helps and good luck to you.

Thanks for the info JIS001, it slipped my mind about the VVT gear.
