Default Special tool for pulleys

Hi,

What is the special tool required when removing and installing the auxiliary shaft pulley and camshaft pulley?

I already have the special tool for the crankshaft pulley.

Shouldn’t these just come right off? I have never used a tool to remove them after busting the bolt loose.

The correct tool for busting them loose is an impact wrench by the way.

People think Volvos are good cars until they drive cars that are actually good.

We use a tool like this to hold the cam gear when torquing the cam and aux shaft bolts.

I use the Volvo special tool to remove the bolt and torque the bolt at reassembly.

Oh yeah I just use an impact on them. The aux gear spins more freely so I use the old timing belt to hold it in place.

Sure impact is great for removing stuff. But you need something to hold it when torqueing the bolt to the 36ftlb it is supposed to be. Other wise it could be overtightened and in extreme instances it can damage or even ruin the cam or IMS.

So at least get one of the suggested tools to help have a happy reassembly.

This is probably true, but having done 15+ in the past couple years, I have a calibrated impact wrench and x amount of dugga duggas gets her done. No come backs yet, and LOTS of miles logged

FWIW, my iPd crank holding tool also holds the cam gear and aux gear because the spacing is the same. However I’ve noticed this isn’t always the case on older cars aux shafts

I use the holding tool from IPD along with an impact wrench. Works just fine and is a worthwhile investment IMO.

Remember this is tb. People are going to choose the path of least resistance. It's quite possible the bolt will break and then the cam or IMS will need replacing.

My impact has a maximum of 140-160 ft-lbs i think, i really don’t think it has enough torque to snap that hardened bolt, but I never even go until it stops anyway. I just blip it a few times.

Take an extra few minutes to torque to a specific number. it's one of the locations on the engine that should be.

+1 on that. Years ago we were warned to never tighten cam bolts with impact because people had broken off the ends of cams that way. This was on pushrod Volvo's.

Edit: those have threaded ends and a nut. Could be a different outlook for breakage.
