Cam seal may need replacing. 2001 S40

AlanS · Post by **AlanS** » 22 Mar 2011, 15:45

I need to change the cam seals and timing belt on my 2001 S40...the S40 forum is no help. Any ideas? Is it basically the same as my 1995 850? I never changed seals before...they are leaking. I might as well change all the seals. The mechanic wants $400 for the deal (without parts). I figure that, maybe, I can do it, and have some new tools in the end (crank puller?, pulley stabilizers). I am a tad fearful.

The 4 cylinder white block motors are not much different from the 5-cylinder. The annoying thing that you're going to have to deal with on the S40 is the VVT camshaft.

I've attached instructions from VADIS below.

My computer has decided that it doesn't want to export PDFs tonight. I'll get you the print-out in the morning.

Here you go.

The instructions also include how to set the timing on the VVT camshaft once you set the belt on.

Now I am really scared. What is a VVT camshaft? ...I fear screwing up timings. If I mark carefully, really carefully, can this job be done with success?
Also, it has been recommended that since I am in there, change the CRANKSHAFT seal. More timing issues!!!! But I want to save the $400 in labor that the shops want.

Not a big deal. Your S40 has variable valve timing on the exhaust camshaft. It simply means that you have to do more than line up the timing marks like on the 850 motor to make sure the timing is set right - read through the last few steps of the procedure and it will explain it better than I can.

I will look up and attach instructions for the crankshaft seals as well.

OK...but I am stressing out about this. Questions: How do I remove the crank pulley, because I want to change that seal also. PLUS...I do not have an impact driver. I have a small compressor. Also, if I remove the top pulleys to do the cam seals, how do I assure that they don't move? When doing the belt alone, I would use the pulley stabilizer that locks the two...but taking the gears off...ahhhhhh! And then assuring that the crank doesn't move!!!!
I WILL do this job (hell, I did the A/C evap last summer...removing the entire dash, etc., have done two heater cores, suspension, etc....I can do this job!)

Hi, I have a 2001 S60 Volvo (with VVT). I removed the cam shaft on the intake side to change the cam shaft seal. How do I line up the valve timing on the intake side with the cam shaft pulley? Thanks

So long as you remove the cam gear and put it back on in the same position as you took it off, I can't see where you'd have a problem. Find something and make a good mark on the engine and cam gear before you remove it. After that, you'd follow the procedure back and forth to center the tensioner at the correct position.

Carefully turn the crankshaft clockwise until the timing belt is tensioned. The belt must be tensioned between the intake camshaft pulley, the idler pulley and the crankshaft
-Hold the belt tensioner centre screw secure. Turn the belt tensioner eccentric counter-clockwise until the tensioner indicator passes the marked position.
Then turn the eccentric back so that the indicator reaches the marked position in the centre of the window
-Hold the eccentric securely. Tighten the centre screw. Tighten to 20 Nm.

As you said before, the S40 section of the board doesn't get a whole lot of traffic, and I don't have a car that has a VVT motor. I would suggest that if you have further questions as to the whole process to send moderator JDS60R a PM and ask if he can respond in the thread - he has worked on many of the newer models and can offer you better advice than I can from looking at these instructions and applying them to what I know.
