Cam seals on a V70/S60R

[isaac]

So I’m about to do this job on my 04 V70R and am pretty intimidated by the dual adjustable timing gears. Is there a trick to really making sure those things are set right and aren’t misadjusted? Thanks!

First, install Volvo special tool 9995451 through the proper hole in the block to lock the crankshaft in position.

Then install Volvo special tool 9995452 onto the non-sprocket ends of the camshafts to lock them in position. You'll need it to torque the VVT sprocket unit retainer bolts to 120nm (88 ft-lbs). And also to loosen them (feels like a LOT more than 88).

Then do the rest of the complicated and precision stuff.

Honestly, I never lock the crank. In fact, I don't think the VIDA instructions even tell you to lock the crank. Turn the crank until the line lines up and you can get the cam tool on. Then just don't touch the crank.

This, tho had one green-horn mech second guess/not trust the crank mark (which isn't always TDC on #1 except on the 4-hole S40 whiteblock?) & use a chopstick to put #1 @ TDC, do a T-belt & bend uhhh...IDK...something close to all 24 valves?
I couldn't believe the engine started looking back on it/noises it made after the fact!

'murika idiocracy / elroy FTW?

Tho that one was particularly funny to me because it takes a certain kinda foreknowledge/imagination to even think to do that, but also not refer back to the factory manual or check with the spark plugs out that it spun over no resistance/bending of valves or something by hand gently once the t-belt was on IDK?

Poor kid just outta auto-tech school finally fessed up to it.
Nice kid, didn't get fired, but did have to go source a head on his time (pistons survived that little mis-adventure) & recondition it.
One of my favorite bumper sticker slogans applies I think?
"oh no!,
not another learning experience!"

I don't use the crank lock tool, either, but technically I suppose if you use both cam & crank lock tools, you can't get it 'wrong,' easily...tho where there's a will & smarter (deviant/imaginative?) idiots, there's gotta be a way!

Far out. I was gonna keep the car in gear and pull the parking brake.

I was more interested in the variable timing gears since they have to be reclocked on the way back together.

I outsourced that operation myself.

You need the cam lock tool.

Turn the crank until the bottom line lines up and the VVT marks line up with the marks on the cover. Roughly, It doesn't need to be BANG on.

Remove the rear cam sensors and reflector wheels. See if you can turn the crank back and forth enough to get the cam tool on (separate it at the center) then you can mount the two pieces of the cam lock on each cam, rotate the crank until they touch, then lock the center of the tool.

Loosen and remove timing belt.

Remove center bolts for the cam gears and remove cam gears (VVTs) (oil will spill out).

Install cam seals.

Install the cam gears (VVTs). ONLY put the center screws in finger tight.

Install timing belt.

SET THE TENSION on the belt with the VVT cam marks as close as you can get them to the marks on the cam cover as possible.

Once the belt is tensioned, set the torque of the center bolts on the cam gears (VVTs).

Remove cam lock tool.

Reinstall all components.

You're done.

I left out the aux belt, covers, wiring harness you have to move out of the way. But that is all pretty straight forward.

Not sure why not... it's right there in the kit on the top shelf, right between the "clamp the head down straight and level" tools.





And at the moment IPD has a kit On Sale for $219.

You have to remove the starter to lock the crank. Why spend all of that time doing something that you don't need to do?

And again, I'm 99% sure the Vida instructions do not mention locking the crank. But I haven't had to look at the instructions for cam seals in probably 10 years.

I guess working on other people's cars in a shop, we try not to just "wing it" and hope for the best. If there's a procedure called out, we follow it.

So, if our ALLDATA says:

Remove the starter motor mounting screws.
Pull out the starter motor and put to one side.
Remove the blind cover plug from the hole for the adjustment tool.
Turn the crankshaft clockwise slightly.
Install adjustment tool 999 5451 ADJUSTMENT TOOL
Ensure that the tool bottoms out against the engine block.
Turn the crankshaft counter-clockwise until it stops against the adjustment tool.
Check that the marking on the crankshaft timing gear pulley corresponds with the marking on the oil pump.

Then that's exactly what we do.

There's other things like:

Note! Crankshaft and camshafts must not be turned more than is stated in the method description!
If the shafts are turned in any other way the valves may be damaged.

For some reason, the boss man doesn't feel like having to replace a head or an entire engine if something goes wrong because a procedure was skipped. Liability and all that. Plus, I don't feel like getting fired.

But, for an owner working on his own car under a tent, feel free do do it any way you like.

^You're not 'wrong,' but if it's auto-tragic & you don't move the crank/roll it over by hand after or are reasonably confident you can remember that the crank isn't 'locked,' it's fairly low risk to skip the crank pinning, no?

It has a mark behind the crank pulley that's fairly fool-proof, after all, eh?

They still kinda make me nervous / all those neglected beat to hell whiteblocks with rattly VVT gears or clogged solenoids with cheap oil not changed on time to inspect for...various things...now that we're ~30 years into the whiteblock saga...
...& ~20 years into outright Ford controlling share/american business model top-down slow implementation/imposition...
...& ~10 years into the Ford-Geely hand/spin-off...
...what's the next turn in the road?

At least we still have a Volvo-only dealership that's been here since 1957...
...can't say the same if ya got a...SCAAB?

I get the feeling I'll be the "lucky" SOB that gets to do a timing chain on the 2000 9-3 waiting outside.
I assume it's the "SAAB Cam Timing Kit" box a couple of rows to the right.

^All I see is access to ~$50K(+?) in tools?

Bad news: You're low man on the totem pole partnership in grime?
(someone's gotta do the diagnosis & repairs/work)
Someone's gotta know how to deal w/those cars & will be the big weiner of that 'prize' / 'cornered' market.

I'm a Shop Foreman at a Volvo dealership and we follow Volvo's VIDA instructions. Hence why I suggested VIDA has no mention of locking the crank when doing the Cam seals. I don't know what AllData (Halfdata?) says.

Since starting in 2006, we've never had a bent valve without locking the crank.

I am all for following the instructions YOU have at your hand.

EDIT: wanna buy my special tool? $45 shipped and it's yours.

I really appreciate the step by step. This is how I’m gonna do it. Hope I can be in and out without anything breaking and hopefully less than a day.
