2000 V70r Timing Belt Help Needed

[Guest magnato1]

Hey everyone,

Trying to do a timing belt replacement on my 2000 V70R. I am doing it with some brief instructions that Lucky gave me, but they skip a few things that are rather important and I can't seem to find him. Here are the instructions he gave me:

"For that model the only necessary 'special' tools are;

Serp belt tool

Torx sockets

30mm crank shaft socket

Be advised a good manual is invaluable for this job so I highly recommend using one.

For a first timer plan on allotting at least 3-4 hours just so you don't rush it. Cam timing is critical with a CVVT car so follow the steps below closely as they relate to how to properly line up the cam/crank marks.

1. Remove Serp belt, timing cover, etc.. to gain access to the timing belt.

2. Rotate the engine over BY HAND until the crank and cam marks line up.

3. Note the cam mark on the CVVT head will likely be 1 tooth or so off (this is normal) and remember this for later. Digital camera FTW.

4. Rotate the engine clockwise BY HAND a further 90 degrees at the cams

5. Now rotate the engine back 90 degrees counter clockwise BY HAND, now all the marks should line up (both cam and crank marks) properly.

6. Loosen the tensioner and remove the belt, reinstall belt and tension properly.

7. Reassemble rest of the bits.

Now this proceedure is not complete from a timing belt remove and replacement sense, the intention is to cover how to 'unload' the spring tension in the CVVT head and align the marks prior to removing the belt and installing the new one. If you just pull the belt off without unloading the CVVT head, the force will not be with you.

Now as a final test, and with everything but the timing cover reassembled, rotate the engine over clockwise twice by hand and verify that there is no piston/valve interference and that the marks line up in a similar fashion as they did during step 3. If they line up correctly, reinstall the timing cover and start the engine to verify proper operation.

Let me know if you need any further help!"

So, the problem I am having is that I cannot get the crank pulley off. Is there a way to get it off without using an impact wrench? Basically, I need a way to secure the crank shaft so that I can crack the nut with a breaker bar. I thought about putting it into gear, but I don't want to screw the tranny. Any suggestions?

An impact wrench is required unless you have the special spanner wrench that Volvo uses to hold the crank from moving. Keep in mind that when you do get it off with an impact wrench, there is always tightening it back up! You'll need that tool there too unless you come up with a means to hold the crank from turning while torquing that big nut. I improvised since I had gotten it off but hadn't thought it through what I would do to tighten. So I snugged the big nut, then installed 2 extra long bolts (the 10 mm ones), that were grade 8. I ended up using some socket headed ones. With 2 bolts installed to full thread, but not tightened, I used something like a tire iron to wedge into the 2 sticking out bolts and let that swing until the tire iron jammed against the frame, and I was able to tighten. I'm not endorsing this method as there is the risk of breaking one of the bolts off, and if you don't have the skill set to get it out, it might be a really bad idea.
