I (tried) to replace timing belt on my S60 -05 with B5244S engine. All went good until I had to remove the crankshaft nut to get the vibration damber out.

I did made my own 'special tool' to hold the vibration damber with those for bolts and it wasn't thinnest material I made it from yet it started to yield before the crankshaft nut opened.

So I started wondering that is the nut threaded left handed? I couldn't find any info about it saying that it would be so I assumed that it would be normal right hand threaded, but boy it is stuck. I also tried with impact, but no help either. Could it be locktited in or just that tight?

First time I had to take timeout when changing timing belt.

 

The times I did it was with an impact but make sure not to use any extensions, it only weakens the impact force. It is a normal nut, so left loosey.

 

Yeah, I had no extension on impact and I even went and got shorter air hose to limit the losses there, but nothing. Hopefully last guy didn't cross threaded it!

 

I hate to be that guy, but I don't bother pneumatic tools anymore for the most part. The Milwaukee I got puts out so much more torque it's crazy. Although I don't have any quality air tools and only a basic compressor so that could be it too.

I am not a fan of it, but I have seen people use the starter to get that nut off by cutting off the fuel and setting up the wrench/socket and cranking the engine. But like I said, absolutely not a fan and its sketchy lol. Plus you run a potential chance to damage the engine after the nut comes loose

 

I'm still stuck(?) with pneumatic tools. Haven't gotten to invest to electric (yet).

Yes, I am aware of that starter trick but never actually used it myself since I've managed to open that bolt/nut always before without that trick, but for some reason it is really stuck now. But now that I know it's normal not and nut left hand threaded I'll have to think something else. Maybe see if I can borrow beefier air impact and/or electric. Of course this would be perfect excuse to buy own electric impact.

 

For electric tools, they always have sales going on. I wait until I see a decent one so you can get a tool with extra batteries or a charger that comes with tools and batteries. I spent $350 and got the better Milwaukee 1/2" impact, a 6 and 2 amph battery, the 12v/18v charger combo and a impact driver tool. The next tool I will get is the 1/2" stubby impact

 

I already have Ryobi's electric drill so I have those batteries and charger, but seems that Ryobi's electric impact is bit on the weaker side based on the specs.

Oh well, have to think something. At least I didn't break anything today so that's a win. I understood to stop before I broke something. Not always the case.

Thanks, anyway.

 

Well, belt is changed now. I went and bought electric impact gun. Even though in paper it has half as much torque as the air impact the crankshaft nut opened without any problems. Should have bought it way sooner.

And engine started after belt change so not too bad!

 

Awesome, glad to hear! Best investment you'll ever make
